"We will enable, help and secure the development of a sustainable future with clean energy supply for our children". Does this sound familiar to you? The websites of the solar investors and sustainable and solar energy funds all declare this great ambition. But, in the end, what counts are the financial numbers. "We need at least 12% ROI on the project. Certainly with all the risks involved". There is this great chorus line, saying "it’s all about the money...".
Better than 2% at your savings account
Have you ever seen a solar fund promoting an offer of a 6-7% guaranteed return on your deposit? It would still be a much better alternative to the 2% on your savings account at the bank, and I bet there is a great future for such an initiative. No one would become very rich, but it would enable solar project developments for private people at a decent return. It would make green and clean solar power development attractive for many people.
The green or the greedy?
Investors could be put aside as greedy people/companies. But the reality is that they accounted for maybe even around 50% of the global market volume and development in the last 10 years. Without the ‘greedy’ investors probably only a handful of large scale projects would have been built. This means the global market demand would have been much smaller. And the market volumes and industry dynamics would have been different. Module and system prices would definitely have been substantially higher. If it was just aimed at the green sustainable-inspired people and customers, the global PV market development would be focused on residential PV applications, on many small PV systems, with just a few exceptions for companies looking for a green image. So, who will help the development of the solar industry and markets more - the green or the greedy people?
Higher returns now lead to quicker competitive prices
The higher the returns offered to investors now, the faster the global market and industry will grow, and the sooner module and system prices will decline due to economies of large scale production; and the sooner green people can buy their clean energy at low prices. Besides this, the investors and financial institutions and banks will get used to solar as an easy, reliable, predictable, trusted, low maintenance technology - a reliable asset with interesting returns. This will be helpful when solar energy becomes competitive and when further market development requires the involvement of big companies, investors and banks.
Global energy hunger
The more investors are facilitated with good returns [RJW1] on their large scale projects now, the faster the industry will grow; and the sooner this will lead to lower production costs and, finally, competitive price systems. Thus, we can sooner reach grid parity where incentives are no longer needed at all. And the investors will have found out that solar PV is a superb, reliable and sustainable asset for further investments, even if the returns are less. They will stay in this growth business because the world’s energy hunger can only increase.
Money makes the PV world go around
Money does not only make the world go round. With solar energy, higher subsidized returns speed up achievement of grid-parity, where government support is no longer needed. A 'quick money shot' with good returns will fire up the PV market and keep it running forever. This 20 year period of FiT-payments will still be ‘nothing’ compared to the incentives, tax advantages and environmental tax exceptions that the fossil fuel industry received over the last 70 years. The PV industry will be like a gasoline engine. The initial ignition takes some (money) fuel. But once it runs, it’s hard to stop. And with solar PV it will never stop as the energy source is infinite and the cost competitive.

Solar module prices come down another 20% in just five months
Growing industry and government budget cuts force prices to drop
Solar modules prices have dropped by another 20% during the first five months of 2011. Top-brand modules are now available at $1,40 per watt and sometimes even less. Half-way through 2008, the sales price still stood at around $4 per watt. Why are prices plummeting and where will this end?
A decade of continuous growth
Last year, the global solar PV market grew an astonishing 100%. For any industry in the midst of a global economic crisis, this is not a bad result. And it was not the first time this spectacular growth had occurred - it first happened back in 2008. Only in 2009 did the global crisis hit the PV market, slowing growth down to around 15%.
Since 2001, the global PV market showed an average growth rate of 50% of new installations per year. No wonder the solar industrial players invested heavily in capacity expansion. After a decade of continuous growth, it does not look as if there is any turbulence ahead for the solar PV market. After all, governments will continue to seek sustainable energy solutions and fossil fuel independence. And as for the end user, the majority would definitely prefer clean solar energy if available at competitive prices.
Still more industry entrants
Even more stimulated by the glorious market demand figures we saw in 2010, the solar industry invested heavily in capacity expansion. This will bring down cost and sales prices, helping it to reach the holy grail of grid parity even sooner.
But, besides the rapid growth of the existing industry leaders, many new players have been attracted too by the growth figures and market forecasts. New small companies and very large (Asian) corporations have started to produce silicon, cells and solar modules. And why not? Market saturation is nowhere to be seen. It does not look as if the solar energy market will stop growing some day - apart from the odd temporary slow-down.
Government budget cuts
At the same time, governments of leading markets saw budget claims for Feed-in-Tariffs in 2010 go through the roof. In the light of general budget cuts and economic problems, Germany, France, the Czech Republic and Italy therefore decided to cut back the FiTs and other grants for 2011. The purpose of this move is to cool down the explosive market growth and excessive budget claims. Not only did they lower the tariffs (subsidies); the revised schemes mean that smaller and roof systems are favoured over big ground-mounted power plants.
The subsidy reductions are forcing the solar industry to reduce cost and system prices in order to remain attractive to its customers, ensuring it still provides an attractive return on investment. Besides, the shift from fewer large-scale power plants to more smaller-scale systems will be a more costly job in terms of sales efforts.
Governments cutting budgets to cool market growth
The result of a rapidly expanding industry on the one hand, coupled with budget cuts on the other have led to a rapid fall in prices. The industry is growing at full speed, and facing more competition in the major leading markets. Germany, France, the Czech Republic, Italy, etc. are being cooled down with seriously lower incentives. This parallel development produces a cocktail which will bring about a rapid price decline for solar modules, inverters and total solar PV systems....
In order to control further budget cuts, these countries will calculate their FiT levels for 2012 in accordance with market growth in 2011 or on solar module price development. It is even possible that these leading markets will (slightly) shrink in 2011 (Germany, the Czech Republic, Italy) compared to the record year of 2010. Although the dynamics are hard to forecast, the promising emerging markets (India, China, etc) are yet not big enough to make up for any slower growth in these leading markets. Nevertheless, with system prices going down rapidly, it might very well be that we can expect another year of global growth.
Spiral of declining prices
Of course, new markets are popping up. But governments closely follow the leading markets, introducing FiTs and incentives according to the latest market prices. In the UK, the incentives for large-scale power plants were drastically cut, even less then a year after their introduction.
Inevitably, this spiral of developments leads to (rapidly) falling system and component prices. And the dynamics are hard to control. The existing leading industry players will fight hard (i.e. lower their prices) to capture and increase their share of the market. New players will fight hard to enter the market. And if the market continues to grow substantially, governments will lower the FiTs even more in order to control the overall budgets.
Where and when will this spiral end? Well, not until solar system prices have reached a point where subsidies, grants or FiTs are no longer necessary to make solar energy competitive with other energy sources. And in some markets, this is already a close call for certain market segments. Germany and Italy, with high electricity prices, are serious candidates to reach grid parity for residential customers next year.
New era of strong growth on the horizon
Industry leaders and experts forecast that solar modules will be sold for under $1 per watt three years from now. An average decline of module prices of around 7-10% per year. Large solar PV systems and power plants could then become feasible at $2 per watt. This will lead to competitive prices for solar electricity, without any government support.
Inevitably, this development will change the business models. In the near future, solar PV systems will be sold as energy and cost saving devices - whereas currently they are sold as profit generators based on government subsidies. With regular electricity prices likely to increase, and as solar system prices continue to decline in the near future, an infinite market is appearing on the horizon. The solar industry can prepare itself for an era of continuous tremendous market growth. But first it needs to fight to get itself through the coming years.

Solar Power Plants Are a Future Goldmine
Solar energy too expensive? It depends how you make the calculation. How long will a PV power plant last? The general practice is for investors to base their calculations on a 20- to 25-year period for a megawatt ground-based PV system, using a fixed structure to calculate the return on investment. Does this give a correct calculation? Why not base it on 60 years and consider the replacement of inverters every 10 years and modules every 20 years?
Is a 25-year depreciation period realistic? What is possible with a PV power plant after 25 years? You could replace the modules by super cheap new modules. The inverters will have been replaced 5 years earlier and will still be doing fine. The rest of the system - concrete, cables, steel structures - are not likely to be eaten by rabbits or ants. Permits and grid connection are most probably still valid as well, since the world is desperate for electricity. So, by replacing the modules with new efficient cheap blue gold panels, available for - who knows - maybe as little as $0.50/Wp, the megawatt power station will be as new. Ready to produce electricity for a further 25 years.
One thing is sure: If a PV power plant is completely depreciated in the first 25 years, the production cost for electricity in the next 25 years will become extremely low. Making it a serious contender to compete directly with electricity from coal and nuclear power plants... And who would believe that electricity on the market will be cheaper in 25 years? In other words, the renewed PV power plant will, once again, become an extremely profitable electricity production site...
It is like renovating your house or building. Replace the windows, but keep the walls and structure intact. Maybe a new kitchen and a lick of paint will give the house a value even higher than ever before. So why, in a world of growing energy needs, would a PV power plant be worth less after 25 years? Isn’t it more likely that the plant is worth even more?
Why would coal and nuclear power plants be depreciated in 50 years and PV power plants in just 25 years? Don't coal power plants present higher risks? Who will be able to estimate what coal prices will be in 25 years' time? Or the costs involved for CO2 emission rights? Or, indeed, other emission reduction measures which may be introduced? These figures certainly seem to be less predictable than what the cost of solar energy will be in 25 years' time. However, it will be difficult to ascertain just how much cheaper modules will be 25 years from now...

10 Myths About Solar Energy
“Solar panels are unsightly, have low efficiency, cost tons of subsidy money and have a high carbon footprint. “
Edwin Koot writes about the 10 major myths about solar energy.
1. Generating Solar Energy Is Only Possible In Countries With A Lot Of Sunshine
The fact is, the energy of the sun is the most evenly spread source of energy in the world. In any part of the world where there is light, solar panels will work. The world’s biggest market for solar energy is … Germany, a country not particularly blessed with long days full of sunshine, but a country with a smart government nonetheless. In the summer, more than 10% of the household electricity in the south of Germany is generated by solar panels.
Of course, when you’re living in the Sahara region, your ROI will be higher, but there are many other factors playing a role, such as the presence of a grid, the local consumer price for electricity, your energy usage pattern, the political stability in a your country, your need for independency from external sources of energy, and many more. As an example, in Northern Alaska it is smarter to invest in solar energy than to pull a cable from a far away power plant or grid connection point.
2. Solar Panels Are Only Attractive In Niche Markets
Solar energy is an attractive product in any place where people need electricity, which nowadays is anywhere in the civilized world - globally. That is a much larger market than just large-scale solar plants in desert areas, which are very competitive markets, because they need creation of new grids, are competing with wholesale prices for electricity and are crowded with many other power-generating enterprises.
When you concentrate on solar panels for household or entrepreneurial use that can be mounted on a rooftop, you can compete against the local consumer and corporate rates for electricity. You can compare this with the market for compact fluorescent lamps, where the consumer at the end of the day saves money by investing a small sum of money. The ROI is made at the end-consumer level: the height of the electricity bill. The investments are very simple, and no new grids or other types of costly infrastructure are needed.
3. Solar Energy Needs A Lot Of Public Financial Support And Could Never Become Competitive
“People will never buy laptops.” “Flat screens televisions are too expensive for the general consumer market.” “Mobile communication is too expensive in comparison with landlines.” These are some of the opinions that we have heard in the past, and how untrue they were! Laptops, flat-screen televisions and mobile phones are now everywhere, because people wanted them, needed them and were willing to pay for them, and finally the prices went down because of mass production methods that could be applied for the innovative products. The same is now happening with solar energy systems.
In the past three years, the prices of solar panels have gone down by half, as a result of the introduction of large-scale production methods. Marketing research shows that innovative consumers want solar energy now. In 5 years, your average consumer worldwide will want his solar panels, just like he wants his smart-phone and laptop. Your consumer will want them, because the solar energy from those panels will be cheaper and greener than the electricity from the grid.
Public funding was created in the past to accelerate this process of acceptance by the general consumer. In the largest markets, the subsidies are now in the process of being terminated. By next year, in Italy and Germany solar energy without any form subsidy will already be cheaper than electricity from the grid. The other European countries will follow this trend soon.
And other countries worldwide will follow, for the simple reason that the global market is getting bigger and bigger and solar systems are getting cheaper and cheaper. That is one thing for sure. The other side is that nobody knows what the costs for traditional energy will be in 10 years. Today, new nuclear plants won’t be even build without substantial government funding, because their future is so insecure.
4. The Efficiency Of Solar Panels Is Still Too Low
True, it could be better. Like cars getting more economical every year, solar panels are getting more efficient every year. Are the current panels not good enough? No, the technology is mature and the panels are good. What is at stake now, is not the efficiency of panels, but the price per generated kilowatt-hour. It is no longer about the type of motor in a car, but about how much fuel the motor consumes per mile.
There will still be new types of solar panels developed, with better efficiency, but the real success of solar energy in the future will lie in large-scale production matters and growth of the global market. A low purchasing price for a solar panel will be the determining factor for low-cost generation of solar energy for the consumer.
Are you waiting with buying a car because the models will be better, faster and greener in 2 years? Not if you need a car right now … In the same way, people need solar panels right now and buy them now, because they help them realize certain goals, such as independency from the grid, lowers costs for electricity and a carbon footprint shift. No new technologies are needed to create a breakthrough for solar panels. They are the breakthrough.
5. Solar Panels Have A High Carbon Footprint And Are Not Sustainable
Solar panels are usually made from silicon. Silicon is found in sand, one of the most widespread natural elements on earth. The ovens used to transform the sand into silicon use a lot of energy - that is true. But the payback time for the energy used to produce a solar panel is only 1 to 2 years. This means that in this time the panel generates the total amount of energy that has been used for its complete production - thanks to the free energy of the sun.
All power generated after the payback time is pure green profit, while solar panels can last 25 to 40 years! Other sources of energy have much longer payback times. Specifically, nuclear power plants have extremely long payback times, so long that it is questionable whether all the power that was generated during their lifetime is enough to pay for the energy used to build and disassemble them.
6. Solar Panels Are Unreliable, Because On Cloudy Days And During The Night They Do Not Work
Right now, the market for wind energy is (still) bigger than the one for solar energy, although the sun is a more reliable source of energy than the wind. But solar energy will soon surpass wind energy, firstly because solar panels can be used anywhere and secondly because they can be implemented in a modular way. This means that is very easy to expand the solar energy system in the course of months or years.
The combination of solar and wind energy is a nice option, but the future lies in the combination of solar energy with energy storage on a local and on a central level, especially now that the market for transport of electricity will grow further.
The market for central storage of energy is also going to be a phenomenal growing market. Central storage of energy in batteries creates the possibility to store the power generated during the day and use it in the night. An example is charging your electrical car at night. Energy storage is already a hot item - you only have to think of laptops, iPods, iPads and electric scooters and bicycles - but solar energy will give this market a big boost. The combination solar power generation and energy storage for later use is a perfect one.
The markets for central storage of energy and for solar energy systems will stimulate each other mutually, because when storage gets cheaper, it becomes cheaper to generate solar energy with the purpose of storing it and using it at a later time.
7. The Big Energy Corporations Do Not Believe In Solar Energy And Thus It Can Not Be Good
Shell finished their engagement with solar energy already. Exxon does nothing with solar energy. Many large energy corporations prefer to invest in coal power plants. But, don’t expect a wholesale slaughterhouse to specialize in gourmet green meat products. Shell has oil in its blood and their business is based on it. Large multinationals are like large tankers on the ocean: they are very difficult to maneuver and cannot make quick changes in course.
Solar energy is a sport for fast and flexible entrepreneurs, with a preference for innovation and sustainability. The market is volatile and ever changing, like the wind in the sails of an elegant and fast sailing ship. An entrepreneur in solar energy has to be like the shipper of such a sailing ship, sometimes tacking in headwind, sometimes easy-going down the wind, but never windless …
And as such, electronic market giant Sharp, a worldwide market leader in solar panels, shows us that some large companies do believe in solar panels. Sharp understood that mass production of solar panels would lower their price, and that ‘mass = cash’. The mass market for solar panels is about to come into existence – and not just in Japan.
Shell has predicted that in 2040, 50% of the worldwide energy will be generated by sustainable sources. Chances are big that sooner or later Shell will buy one of the consolidated winners in the solar energy market. Some of the ‘small’ solar panel producing companies have already grown into large corporations, with thousands of employees and turnarounds of a few billion dollars per year.
Google grew in 10 years to become one of the largest companies worldwide, so why not a company in solar energy systems?
8. Solar Energy Has No Role In The Global Generation of Energy
At this moment, solar energy contributes to only 1% of the worldwide need for energy. But, this contribution could be growing surprisingly fast. Germany is the guiding country, where it is expected that in 5 years, 10% of all energy used will come from solar panels.
And what Germany can do, other countries can do too. For emerging economies, it has already become useless to build large coal or nuclear power plants when solar panels are getting so cheap so quickly. You can compare this with the introduction of the mobile phone in India and other countries that didn’t even have a mature landline grid.
Those grids were never further developed and will never be, because they were made redundant by the introduction of the mobile technology. The same thing could happen with the introduction of solar energy on the markets of the emerging countries. The building of new, large power plants will become redundant, because individual, decentralized power generation is cheaper, more efficient and much more flexible.
The photovoltaic world market has grown in 2010 with more than 100% compared to 2009, and it already started to grow in this way in 2009. If this logarithmic growth percentage of 100% continues, then solar energy will cover the entire global energy needs in less than 10 years!
9. Solar Panels Are Unsightly And Take Up A Lot Of Space
That really depends on taste. Of course, there will always be people who believe a smoking chimney of a coal power plant is the apex of industrial technology and esthetics. Other people don’t mind showing that they are generating their own electricity and therefore have solar panels on their roofs. Anyway, there will always be enough space on earth for all solar panels ever needed.
Mind you, only a relatively small desert area of 200 by 250 kilometers (125 by 155 miles) filled with the solar panel technology of today would be needed to fulfill the total need for electricity of Europe. But, luckily, we don’t have to enter into those beautiful desert landscapes, because there is enough roof area available in Europe to realize this supply. And on a lot of roofs, the panels won’t even be visible.
Also, more attractive panels will be introduced on the market as production methods and innovations proceed. Compare it with the cars of today, which are so beautiful, compared to the vintage cars of the ‘60’s and 70’s … or not?
10. Solar Energy Systems Are Unreliable And Require Maintenance
Solar energy systems do not have moving parts and therefore require no or hardly any maintenance. The most fragile part in a grid-connected solar energy system is the inverter, which converts the DC from the solar panels into AC equal to the voltage of the grid.
An inverter costs about 10% of your total energy system costs. It consists of some pieces of micro-electronics, can last about 10 years, and can easily be replaced for a then probably even low price.
Only in dry and dusty climates, it can become necessary to clean the panels regularly with a little water. If you live in an environment where it rains often, you don’t even need to do that.
A recycling program for solar panels has already been put in place in many countries, so if after 25 years of loyal service you would need to replace your solar panel, the solar energy sector has processes to recycle all panels for 100%. And no coal power plant can beat that.

At this moment, solar energy contributes to only 1% of the worldwide need for energy. But, this contribution could be growing surprisingly fast. Germany is the guiding country, where it is expected that in 5 years, 10% of all energy used will come from solar panels.
And what Germany can do, other countries can do too. For emerging economies, it has already become useless to build large coal or nuclear power plants when solar panels are getting so cheap so quickly. You can compare this with the introduction of the mobile phone in India and other countries that didn’t even have a mature landline grid.
Those grids were never further developed and will never be, because they were made redundant by the introduction of the mobile technology. The same thing could happen with the introduction of solar energy on the markets of the emerging countries. The building of new, large power plants will become redundant, because individual, decentralized power generation is cheaper, more efficient and much more flexible.
The photovoltaic world market has grown in 2010 with more than 100% compared to 2009, and it already started to grow in this way in 2009. If this logarithmic growth percentage of 100% continues, then solar energy will cover the entire global energy needs in less than 10 years!
9. Solar Panels Are Unsightly And Take Up A Lot Of Space
That really depends on taste. Of course, there will always be people who believe a smoking chimney of a coal power plant is the apex of industrial technology and esthetics. Other people don’t mind showing that they are generating their own electricity and therefore have solar panels on their roofs. Anyway, there will always be enough space on earth for all solar panels ever needed.
Mind you, only a relatively small desert area of 200 by 250 kilometers (125 by 155 miles) filled with the solar panel technology of today would be needed to fulfill the total need for electricity of Europe. But, luckily, we don’t have to enter into those beautiful desert landscapes, because there is enough roof area available in Europe to realize this supply. And on a lot of roofs, the panels won’t even be visible.
Also, more attractive panels will be introduced on the market as production methods and innovations proceed. Compare it with the cars of today, which are so beautiful, compared to the vintage cars of the ‘60’s and 70’s … or not?
10. Solar Energy Systems Are Unreliable And Require Maintenance
Solar energy systems do not have moving parts and therefore require no or hardly any maintenance. The most fragile part in a grid-connected solar energy system is the inverter, which converts the DC from the solar panels into AC equal to the voltage of the grid.
An inverter costs about 10% of your total energy system costs. It consists of some pieces of micro-electronics, can last about 10 years, and can easily be replaced for a then probably even low price.
Only in dry and dusty climates, it can become necessary to clean the panels regularly with a little water. If you live in an environment where it rains often, you don’t even need to do that.
A recycling program for solar panels has already been put in place in many countries, so if after 25 years of loyal service you would need to replace your solar panel, the solar energy sector has processes to recycle all panels for 100%. And no coal power plant can beat that.

Imagine the “Impossible” PV Growth Scenario
Without a vision there is no mission; without a mission there is no action. The vision of a world being powered by solar energy might seem impossible - but it makes sense to seek a way to make it possible.
Man on the Moon
In most cases, the impossible is in fact feasible, if we just try. If you had asked in the 1950s whether it was possible to send a man to the moon, people would most likely have laughed in your face. Only a little over a decade later it happened. Although there are some skeptics who still believe it all happened in a Hollywood studio... but who can blame the disbelievers? In the USA anything is possible.
Now, let’s take a look at solar PV. All of the last decade’s forecasts in global market growth have been surpassed. With the exception of the somewhat modest growth experienced during the “crisis-year” 2009, 2008 to 2010 saw the global market growing an astonishing 100%. Numerous markets, for example Italy and Germany, have demonstrated that a growth rate of over 100% is indeed very feasible. So, if they are in a position to do so, more countries will hopefully follow suit. It is a proven model. The solar industry is growing with increasing speed - so fast, in fact, that analysts are worried about an oversupply situation this year for solar cells and modules.
The “Impossible” Scenario
Now, let’s think of “the impossible.” Let’s envision a scenario of a yearly market growth of 100% for the next decade. How impossible is that in fact? It has been done before. What would be the result within one decade?
Well, that would lead to an annual market size of 30,000 GW (yes, gigawatts, not megawatts) in 2021, just a decade ahead. Conservatively estimated, that is equal to the output of around 8,500 GW of new coal fire plant capacity, or equivalent to 8,500 coal plants of 1 GW capacity each. Not bad. And enough to cover up to seven times’ the forecasted growth in global electricity demand till 2020 according to IEA studies. This means we would cover the growth and part of the current electricity demand. It means in fact closing down fossil power capacity for solar power. If we did just two years at 100% growth - and indeed the industry is eager for growth - it no longer seems so “impossible” after all...
33 Trillion Kilowatt Hours of Solar Energy
According to the IEA, the electricity consumption forecast by 2030 will be around 33 trillion kWh. In order to provide this totally by solar PV, based on an average of 1,600 kWh/kWp system yield (assuming most of this power is installed in sunny regions such as India, China, the Sahara, etc.), this would require 20,600 gigawatts of cumulative installed solar PV power. According to the 100% year-on-year growth scenario, this cumulative amount of solar power will be installed by 2020...
The conclusion can therefore be drawn that a continued rate of 100% year-on-year growth until 2020, which has proven possible during the last three years, will be sufficient to cover the entire world electricity consumption in 2020 and onwards. Imagine... this would not only mean unlimited, clean, cheap, reliable, predictable green power for everybody in PV, but also in grid management, energy storage, etc.
Nike and McDonalds
Like the global market, the Germans, Italians and several other countries have demonstrated that 100% year-on-year growth is possible for a few years in a row. There are over 150 more countries to follow suit. The solar industry proved it is possible in 2010, with 118% cell production growth. And I bet the industry is ready to take up this challenge for another decade. The task is to prove that the “impossible” scenario is in fact possible. We are investing in sending people to Mars - it makes sense to clean up the mess on Planet Earth home first, within the coming ten years.
Nike said it in an advertisement campaign: “Just do it!” And to add another famous slogan to that one: “I’m loving it!” too...

Does it make sense to subsidize large scale power plants?
More and more markets in Europe are seriously reducing the feed-in tariffs for large scale power plants. It seems like a trend and the focus is to stimulate residential PV application.
That in itself makes sense. Solar electricity produced on your private roof competes well? with relatively expensive electricity from the grid. In many European countries the cost of electricity for a household is almost twice as high as for commercial customers. Hence, it makes sense to stimulate the application of PV by private home owners. And especially in countries like Italy and Germany with relatively high grid electricity prices. In these countries the residential market segment will be the first that achieves grid-parity.
Volume is what we need
Nevertheless, the success of European PV market growth is partly based on the many megawatts installed in large scale PV power plants. Think of the thousand-plus large scale power plants in Spain. Think of the many multi-megawatt ground-based projects in Germany, The Czech Republic, France and Italy, and the big roof projects in Germany and Belgium. These power plants helped to generate volume in system and module sales. And volume is what this industry needs. To get lower production costs we need economy of scale in module production. In order to make big steps quickly, we need large projects. After all, it could take one experienced EPC less than one year to design and build one 50 MW project. But 50 MW in the residential market equals more than approximately 17,000 PV projects of around 3 kWp. That takes slightly more effort and a few more small contractors to sell, design and install all these systems. These hundreds of small PV contractors are not created, educated and ready to install overnight. It needs a good strategy to create jobs, but it is still more difficult to create a voluminous market quickly.
Big investors exhaust the budgets; not the best message to your voters
So why are governments changing the rules during the game, cutting back earlier and more strongly on the FiT for big projects? The main reason is that the markets are growing too fast and available budgets are exhausted too soon. The total cost spread over the rate payers increases too much. And most big projects are investments by big (foreign) investors making an attractive return on investment. So, rate payers’ money flows into the pockets of big financial parties - these days not the best selling proposition towards your (potential) voters.
Financial institutions should learn to embrace and love PV
Nevertheless, we need these big projects - for the creation of market volume and thus rapidly growing industrial production volume, which will lead more quickly to lower production costs and system prices. For the future we also need banks, investors and the financial world to build up a broad experience with big PV projects. We need them to embrace, love and trust solar PV. Once they love big projects, they will start to streamline their processes to do smaller and smaller projects as well. And on the other hand, once they learnt to do a subsidized 50 MW power plant, they will sooner do an unsubsidized 100 MW plant. And so we will see much bigger projects coming up.
Need for cheap quickly installed PV power
And, we should not forget that the market for big projects will soon grow quickly. It’s not just in the USA that utility scale project development is taking off. China, India and, soon, (South) Africa and South America will embrace big PV power plants. It will be the major PV market segment. These countries are very hungry for new power to meet the rapid growth in electricity demand. They need more energy soon, quickly installed, green and cheap. Large PV plants are and will be the best solution.
Big money makes the PV world go round
If Europeans don’t build up the experience (engineering, financing, management, etc) and business infrastructure in their home markets, they might lose the opportunity to compete with the Americans when offering their services elsewhere in the world. Europe needs to have big financial investors, funds and banks all getting used to PV. We need them to educate and develop our domestic PV business infrastructure and our market. This way we can soon sell our experience and services in much bigger markets beyond Europe. Money makes the world go around. And big money makes the PV market grow quicker, makes cost and prices go down quicker and will sooner bring us bigger PV business.

What Do They Know That We Don't?
Last week, another ambitious Chinese vertically integrated manufacturer, which entered the supply chain last November, published its modest target of 2.5 GW production capacity within 3 years. At full capacity, this company alone would be sufficient to supply the entire US PV market.
And this company is not the only new entrant. You only need to visit a Chinese PV exhibition to get the distinct impression that more solar modules are being sold worldwide than cell phones. With a difference though. In the cell phone business, there are only a few brands. Alongside all these new entrants on the market, the existing top-tier manufacturers are focusing on capacity expansion and forecasting planning ramp-up as well - determined to expand their share of the global market.
European Markets Under Discussion
We all know that the global PV market boomed a tremendous 90% in 2010 compared to 2009. All reports predict a bright future for solar energy. So, from that perspective, it seems logical for new entrepreneurs and major business corporations to step into the lucrative solar industry right now.
Nevertheless, I can’t help but wonder what these new entrants know about the current market dynamics and forecasts in Europe, which in 2010 took 80% of the global market. Indeed, despite the great opportunities, there are nevertheless a few uncertainties which must not be overlooked. Last year’s number 5 market, the Czech Republic, might disappear from the top 10. Indeed, Spain already did so - and there are no signals this market will pick up again in the near future. France is facing a market cap of 500 MW. The UK and Belgium are discussing a ban on large-scale projects. Germany will most probably reduce its FiT by another 15% in July. And this week the Italian cabinet concluded that the FiT Program worked out so well that the original target of 8 gigawatts’ installed capacity might be reached this year. So they need to take stock and think carefully about the next Energy Law, the 4th Conto Energia. Most likely, they will decide to reduce the FiT a little faster and earlier. Luckily, they did not decide to introduce market cap.
Born Pessimist?
Now, I might be a born pessimist, but these developments don't seem indicative of another major boom in Europe this year and the next. So, where will all the modules go? Perhaps I am just missing the bigger picture and developments elsewhere. Maybe the US market is ready to boom and secure global market growth. Or perhaps new Chinese market stimulation programs are still off my radar screen but ready to kick in. Or maybe I am underestimating new markets and new FiT programs such as that in the Philippines, for example.
Or perhaps history will repeat itself, like when the Spanish market collapsed in 2009 and Germany covered all the loss in Spanish demand. Will further new markets perhaps cover up any hiccups which may occur in Europe? Will modules find their way like a river finds the ocean? Would these new manufacturers put their money on this happening again?
Missing Strategic Insights?
In addition to all of this, the price of oil is rising very rapidly. Could it be that we are approaching the peak oil tipping point, with the price of oil only increasing from now on? If so, solar will become competitive even sooner, with solar modules becoming more in demand than ever before. Could it be that these new Chinese producers have strategy reports containing these insights?
The question spinning in my head is: What do these Chinese manufacturers know that we don’t? Or is it perhaps: What do we know that they don’t?
