Solar Panels has suddenly become one of the biggest industrial consumers of the Silver Metal in 2010.The massive growth of the solar industry has surprised analysts and forecasters alike and caused surprising demand in the most unlikely of places.With 15-17 GW of Solar Panel Production estimated in 2010,the silver consumption will be around 65 million ounces or 1800 tons.With production of around 21000 tons,the Solar Industry is now responsible for around 9% of the global Silver production.Note Despite Silver touching new record highs,it has not affected the solar prices much which have continued to decline by almost 50% in the last couple of years.

Renewable Energy Certificate (REC) Policy is starting in India tomorrow which will allow Green Energy Generators to earn additional tariff.Note the REC Mechanism is also present in different forms in Italy,USA and Australia and has proven a good incentive to promoter Renewable Energy in those countries.India's Electricity Regulator (CERC) has been actively implementing different orders to boost Green Energy Generation.CERC had earlier mandated a 6% Renewable Energy Percentage from Alternative Energy which would go upto 15% by 2020.The REC Policy will help in achieving those targets by providing a pseud market linked mechanism to inentivize Green Power Producers.
Who will Benefit
Renewable Energy Companies and Green Utilities are set to benefit the most from this Policy.Suzlon has already welcomed the policy saying that Financing will ease for Renewable Energy Projects.Orient Green Power,the largest Green Focused Utility will also be a big beneficiary.Local Indian Wind Turbine Companies should also benefit from the Scheme.It also provides companies outside the JNNSM to get decent returns from solar generation as the REC band for Solar REC has been set between Rs 12-17/Kwh.India need to increase Renewable Energy Capacity by at least 50 GW in the next 10 year to meet the 15% CERC Target

Solar Energy in India represents one of the best Energy opportunities in the 21st Century.However the growth at least in the initial stages will be geographically unequal.This is due to the fact that Solar Power requires strong government support and subsidy currently.Without a proactive administration which smooths out the process of setting up a solar plant,growth of solar energy is almost impossible.The Indian Federal Government has already given it a strong push targeting 1000 MW by 2013 and 20 GW by 2022 under the JNSSM.While the Subsidy Program is facing some initial hurdles due to debt financing and aggressive project bidding,the long term secular growth story remains good.Some states have also been aggressive in supporting solar energy namely the western states of Gujarat and Rajasthan.

India's 150 MW Solar Allocation to PV Technology has seen overbidding upto 10 times and the winners will be decided based upon the discounting on the Rs 17.91/Kwh (40c/KwH).The discounting promises to be clearly be irrational and loss making as Large Conglomerates and Integrated Solar Companies fight with each other to win projects at any cost.Feed in Tariffs across the world has only worked out well where there is no discounting or bidding mechanism.In case of bidding,especially in immature nascent markets,the winners of the projects end up as the losers.Renewable Energy also ends up on the losing side as many of these projects are not completed or have to be restructured defeating the entire purpose of the Subsidy Scheme.India's Solar Energy Sector promises to be one of the biggest energy opportunities in the 21st Century.However this will require a very smart subsidy strategy by the government

First Solar,the US based Cadmium Tellurium (Cd-Te) is the lowest cost panel producer in the world today if you don't include any penalty for low efficiency.Even if you penalize the Cd-Te Technology for its lower efficiency vis-a-vis the higher efficiency crystalline technology,First Solar is clearly the leader with a core cost of 74c/watt.The company has a roadmap of reducing the cost to 52c/watt by 2014 and given its track record it seems quite achievable.In Cd-Te,some new competitors have claimed even lower costs than First Solar but they have yet to prove it in large scale production.General Electric,Abound Solar are some of the other Cd-Te players which are planning commercial production in a year or two.But with around 2 GW of capacity,they will have a lot of catching up to do.

However Solar Capacity in the Industry has increased rapidly particularly in Taiwan and China.Besides Semiconductor and LCD Heavyweights like AUO and TSMC have made huge investments into Solar Production.Korean Companies are too making a strong entry into the already crowded segment.Despite some capacity build in the wafer and module parts of the supply chain,Taiwan remains largely a cell producer.Compared to the integrated Chinese producers like Trina,Yingli,LDK and others,Taiwanese Solar Makers are vulnerable to sharp price cuts.They depend on European customers who are largely uncompetitive and would face huge pressures with the decline in the German market.Chinese producers have much lower costs due to their vertical integration which currenly most Taiwanese lack except Motech.Taiwanese Cell Capacity is set to increase manifold next year from the current 5 GW.Most of the Tier 2 Cell Producers would be running empty while even Tier 1 players will see a sharp decrease from this year.

Solar Energy Future Growth has been vastly underestimated by policy makers and analysts but private companies are recognized the huge potential.India's JNNSM Policy which is meant to jumpstart India's Solar Energy has drawn huge interest from both domestic and foreign companies.The number of Solar Companies in India are growing at a rapid pace attracted by the huge opportunity.While starting troubles like project financing of debt etc are present,the long term growth potential of Solar Energy in India is tremendous.Global Industrial Giants like GE,Siemens have already established or in the process of investing huge sums of money to capitalize on this Green Trend.Now French Giant Areva has joined them.Note Areva is the global leader in nuclear equipment technology and is not known for its prowess in Solar and Wind Energy.However the company is making a play in Solar Thermal Technology where it hopes to use its existing skills and knowledge.Areva had acquired US startup Ausra which had fallen on hard times earlier.However Areva has not won too many Solar Thermal Projects in the recent past.However things may change starting with India

Australia has shortlisted 8 projects with 4 Solar PV and 4 Solar Thermal Projects for its Solar Flagship Program which will be decided in 2011.BP Solar with 150 MW and Suntech/Infigen with 195 MW are on the shortlist.The other 2 companies are energy utilities which are proposing to use Cd-Te Panels ( I think from First Solar).Note both of these energy utilities are small and might face problems in fund raising and execution.The firms shortlisted for the Solar Thermal Projects don't inspire much confidence either.The selection procedure and how the subsidy will be disbursed has ran into controversy with accusations of bias and partiality.WA has not gotten any projects while Queensland province has gotten most of the projects.The firms shortlisted have also come under fire as they don't have much experience.Not much information on how the firms were shortlisted but these companies are definitely not the best or cheapest by a big margin.Australia has generally made a mess of promoting renewable energy with New South Wales cutting feed in tariffs sharply after giving an overly generous subsidy.The Solar Flagship Program looks like an expensive mistake in the making if it comes to fruition.

Solar PV Technology have made a huge advance in the last 2-3 years leading to a demand explosion with more than 100% growth forecast this year.Crystalline PV Technology as well as Thin Film Technology like CIGs and CdTe have reduced their costs drastically.While Solar PV still requires generous government subsidies for their growth,grid parity has come very close.Solar PV Technology has become economically competitive in parts of Italy where a unique combination of high electricity rates and sunshine have made Solar PV Technology very attractive.Costs are being reduced at more than 10% per year which would make Solar PV competitive in 2-3 years in most parts of the world.However mainstream and reputed forecasters and companies like Boston Consulting Group remain blind and ignorant to this.BCG in a recent report has said that biofuels and Concentrated Solar Thermal (CSP) Technology will become competitive.I have issues with both of these technologies.

AUO is investing massively in Solar Energy to build a multi Gigawatt capacity in partnership with US Solar Efficiency Leader Sunpower.Not only is AUO building a huge factory in JV with Sunpower in Malaysia,it has also made plans to set up a 2 GW Solar Crystalline Solar Cell Fab in Taiwan.This will be a 50:50 mix of multi and monocrystalline technology.Note the solar market despite seeing a massive 100% jump in solar demand in 2010 faces a huge supply overhang from a number of new large players.TSMC,Samsung,Hyundai,Saint Gobain,BYD are just some of the heavyweights ramping up their solar expansion plans.AUO faces a tough time in this crowded market which already has Chinese incumbents establishing gigawatt capacities.A new player needs to differentiate himself in the increasingly commodity market that solar modules have become.

Planned Czech Solar FIT cuts will heavily favor subsidies to Small Distributed Rooftop Installations
Czech has seen the biggest Solar Growth Explosion compared to its size powered by extremely generous feed in tariffs.This has made Czech one of the top solar installers in the world and led to a huge public backlash.The Czech government has responded by proposing to bust the Solar Energy Bubble by drastically cutting down the Feed in Tariffs.The administration is also trying to reign in the ballooning subsidies from existing solar plants by imposing taxes on solar plants and carbon credits.This is being done as the Czech consumers face a 15-25% increase in electricity prices next year.The country had little option as its very badly designed tariffs had led to a situation where Czech Industry faced the prospect of becoming uncompetitive.

Solar Energy is currently the amongst the costliest form of energy generation and except in niche applications is not economic without some sort of government subsidies.However growth in solar energy has been one of the fastest in the past decade upwards of 50% CAGR as costs have declined and technology improved manifold.Solar Energy forms just 0.1% of the the total energy supply of the planet currently and analysts and decisionmakers don't think that Solar Energy can form a big chunk in the future as well.However I differ strongly in that aspect.The main reason for my very bullish opinion on Solar Energy is based on the simple fact that Solar Energy is the only form of Energy whose costs are declining rapidly on a secular basis.In a world facing the prospects of "peak commodity",solar energy remains vastly abundant and it remains upto human technology to capture it at the lowest costs.

Malaysia is set to become one of the largest solar panel producing nations overtaking much larger rivals USA and Japan as world class companies start/expand capacities in Malaysia.Every country is trying to promoter Green Industry in the fight for leadership of this new age industry and to create high paying green jobs.Billions of Dollars in Green Stimulus has been doled out by governments but with varying degrees of success.USA has managed to squander most of its Green Subsidies despite possessing a very strong technological base as US Companies shutter US factories to outsource production to Asia and Mexico.European Countries have seen a similar phenomenon as their high costs force domestic companies to shift to Asia for their survival.China and Taiwan are the largest solar cell producers in Asia due to their low costs,good infrastructure and massive government support.Taiwan has also been able to leverage its semiconductor strengths with companies like TSMC and AUO expanding into solar energy.However Malaysia has been a surprise winner as well.It is important to understand the reasons behind Malaysia's success as it has beat countries with much larger solar energy markets like USA and Japan.It also has no massive semiconductor industry like Taiwan which can redeploy its skills.It has only recently introduced a Feed in Tariff Policy to promote Renewable Energy

Putting up Solar Panels on prominent landmarks is an easy and cheap way to promote Green Energy.In the last few years, a number for prominent places in the world have been installing solar energy in an effort to reduce GHGs and to publicize the clean economy.It advertises the advantages of putting solar panels in powering buildings which account for 40% of the global energy usage.'s Sydney's Opera House,India's Golden Temple are some of the other landmarks that have installed solar panels to cut fossil fuel use and encourage the use of renewable energy.White House has also decided to install solar panels next year after a prolonged campaign by green activists.Note White House had earlier installed solar panels during the time of Jimmy Carter and the OPEC Oil Embargo.These has been decommissioned by Reagan reflecting changed energy fundamentals.India's Parliament House has now decided to go green using solar panels and biomass plants to drastically reduce its carbon footprint.The Indian Parliament generate a huge amount of food waste which will help in powering the biomass plant.

California and the Federal Government have recently approved a number of big Solar Thermal Plants totaling around 2800 MW.These plants utilize Concentrated Solar Thermal (CSP) Technology and uses mirrors and towers instead of normal PV panels.The haste with which these plants are being permitted and approved is mainly due to the expiry of the Treasury Grant Scheme by end of 2010.According the the American Stimulus rules,only Green Projects which have broken ground or spent 5% of their costs would be eligible for the 30% Cash Subsidy.6 Huge Solar Thermal Plants have been approved with the biggest Blythe plant being the most recent.The capital costs for these plants are extremely high at around $6/watt which makes me question their economics.PV panels can be installed at around $3-3.5 /watt which is around 40-50% lower.Despite the higher capacity factors for Solar Thermal Plants and their ability to store energy for a short period,the cost difference is too large.

BYD the Chinese battery and electric vehicle producer made famous after Warren Buffet made an investment has been facing rough times recently.Its falling auto growth,problems with land acquisitions in China and an incoherent strategy has hurt its profits and stock price in 2010.The Company has put on too many hats with investment in various green technologies besides its bread and butter car business.The most ambitious plans of BYD undoubtedly lies in the Solar Energy Business though little details have been revealed.The company is planning to spend 22.5 Billion Yuan on Solar Energy over the next 5 years for which it has already secured financing.The company has started a 100 MW cell plant in the Shaanxi province and plans to expand to 5000 MW by 2015.However its recent travails had made one think that they would have put their aside Solar ambitions .However that does not appear so.

Solar Power in India is growing at a rapid clip with the strong government support through the ambitious Jawaharlal Nehru National Solar Mission (JNNSM).Rapidly Falling Costs,Massive Power Deficits,Huge Growing Energy Demand and Peak Oil all make Solar Energy in India one of the biggest energy opportunities in the 21st Century.People are slowly recognizing this large Green Money Making Opportunity with companies like Suntech,Siemens and Trina Solar entering into partnership with local players.Suntech has tied up with independent power producer IPP while Siemens has tied up for solar thermal energy with the Adani Conglomerate.This is just the initial trickle with large foreign companies waiting to flood the Indian market.There have been some initial hiccups in Debt Financing of Solar Energy in India but I expect the long term secular growth story to be unaffected. Solar Power Companies in India can be divided into various categories based on solar equipment manufacturing,independent power producer,renewable arms of large power companies etc.I have already covered the Top 10 Solar Module Production Companies in my Solar Panels in India article.Here is the list once again.

Concentrated Photovoltaic (CPV) Technology Gaining Ground
Concentrated Photovoltaic (CPV) Technology has found some favor in 2010 with some major projects and investments coming its way.CPV Technology which is a poorer cousin of its more illustrious PV Technologies like c-Si and Thin Film has found some attention with its low cost and high efficiency.US Startups like Amonix,Solaria have found some traction bagging some big projects backed by financial investors.Concentrix Solar backed by European Specialist Wafer Producer Soitec has recently announced a partnership deal with US Energy Efficiency Leader Johnson Controls.With c-Si Technology fast reaching its Efficiency Limits,CPV is looked upon as the way forward for the Technology to progress.CPV Technology works by concentrating the energy of the sun through optics and has the potential to dramatically cut the costs as it uses much less materials.The Technology slowed down because of the polysilicon price crash but has found increasing attention in the past few days

Solar Frontier is a subsidiary of Showa Shell Sekiyu and is listed on the Japanese Stock Exchange.The Company has big plans for the Solar Energy Market planning to increase its capacity by more than 10 times in 2011 to around 1 Gw in total.All its 3 plants are located in Miyazaki in Japan and uses previous plasma plant of Hitachi.Solar Frontier claims 11.5% efficiency for its CIS modules which are expected to go upto 14% by 2014.The Company is spending around $1 Billion in Capex for building the 1 GW capacity implying roughly $1 capex/watt which is not exactly cheap though not very expensive either.Note Thin Film Competition is hotting up with Saint Gobain-Hyundai,TSMC,Miasole,Oerlikon Solar,Sharp,Nanosolar all making plans for huge capacity expansion in the next couple of years.Solar Frontier has signed some small deals for supplying 1-3 MW in Thailand,Japan and Australia Recently.However the cost structure of the company is not known till now just like Sharp.While Solar Frontier looks good on the capacity and partnerships front,it has still to prove itself on costs to really push the Chinese Solar Companies which are dominating the Solar Scene right now with their low cost polysilicon panel production.Note 60% of the Solar Panel Production in Q210 was estimated to be done by Chinese based manufacturers.

The JV with the Adani Group is a win-win for both companies.Adani Group is setting up 16000 MW of Thermal Based Plants in India over the next few years and has also planned a 100 MW Solar Plant in Gujarat.It has started a company Adani Renewable Energy to take forward its Green Energy initiatives.The tie-up with Siemens will allow it to access cutting edge Green Technology while Siemens will get a huge customer for its Energy Equipment.Renewable Energy in India is a huge growth opportunity considering that India will have to increase its Renewable Energy by almost 45 GW over the next 10 years if it has to meet 15% of its Electricity Requirements from Green Sources as mandated by the CERC.

Haryana is one of the richest states in India strategically located near India's capital of Delhi.Haryana cities like Gurgaon and Faridabad have benefited hugely from being part of India's National Capital Region (NCR).However Haryana only generates 0.5% of its 4000 MW of Electricity from Renewable Energy Sources.The state has negligible Wind or Biomass Energy.Despite a Department of Renewable Energy being setup to specifically promote the use of Alternative Energy Sources,the state has not had much success.Haryana is richly endowed with Solar Energy Resources with 320 days sunny days.The State has managed to win some allocation from the centre's JNNSM scheme.It is also promoting the use of solar energy through disseminating solar kits amongst 2000 schools and providing solar lighting in around 500 villages.Note India had already made it mandatory for 6% of the Energy to be generated from Renewable Energy Sources.Haryana has a long way to go and might have to buy a huge amount of expensive Renewable Energy Certificates (RECs) unless it gets its act together.

The HPUC has given a FIT rate which is quite low for solar energy and has failed to implement a policy for installations between 500-5000 KW.Also the FIT rates for Concentrating Solar Power (CSP) does not make sense at all for under 500 KW installations.Don't think there exists a single decent producer of such small CSP plants.The FIT Policy was passed despite stiff opposition from the island's utilities who questioned the Feed in Tariff as a good Green Incentive.The huge success enjoyed in Europe by FIT did not make a big impression.Note 80% of the world's solar installations depend on Feed in Tariffs.While there have been bad implementation cases of FIT in Spain and Czech,there have been huge successes in other countries like Germany and UK.HPUC rightly decided to go ahead as trial and errors would be needed . It won't lead to a huge boom in solar in Hawai due to poor returns however it should lead to some boost to existing solar producers or those who were going to install solar anyway.

1) Tax on Solar Subsidies - The Czech Government which used to give a tax holiday to solar energy revenues will be withdrawn and a new tax rate will be introduced.
2) No more Free Carbon Credits - The administration will generate revenue through selling the carbon credits rather than giving it free to Renewable Energy Producers.This will remove another source of return for solar investors.
3) Rent for Power Plants on Agricultural Lands - The Government also plans to impose a Fee on Solar Power Plants that are built on Agricultural Lands.
Czech is facing a massive economic problem due to the increase in electricity prices at a time of Fiscal Compression.This has been mainly an outcome of huge subsidies being given to the solar energy producers.With almost 1.6 GW of Solar Energy being installed by 2010,the government had no other option than to clamp down and clawback some of the super-normal profits being given to solar investors.

Solar Panels despite being mostly a commodity comes in a wide variety of types,technology,prices,size and colors.You can read an introduction about the lowest cost panels here.With there being no global index of Solar Panel Prices and with Prices of Solar Panels forming very quickly,its a difficult problem in acquiring the cheapest solar panels.The problem is compounded for solar panel buyers because these panels are typically sold by wholesalers and distributors who charge fat margins without providing any additional value.Also due to the lack of knowledge about the quality and the properties of solar panels,buyers generally get fleeced.Also panels are seldom sold separately as it is generally part of the overall package of the complete installation of panels,inverters,wiring,connection and integration.Here is a quick overview of which are the companies which make the lowest cost solar panels on the planet at a good quality and the most recent prices which they are selling at.Notice that the European and Japanese solar panels are of much higher price despite there being very little to differentiate themselves from Asian solar panels.

Note Solar Panels prices differ widely depending on the technology,power,brand and quality.Thin Film Panels in general cost lower than crystalline silicon panels.Higher Power Panels have a higher price as they generate more electricity.Good Brands also have a higher price tag while cheap imported Chinese panels cost less.Solar Panel prices have decreased by almost 50% in the last 2-3 years and now sell for around Rs 1800-2500 per panel internationally and should fall to around Rs 1000 in the next 3-4 years . However for small installations on house of 1-5 KiloWatts,panels sold by distributors is more expensive and can cost you almost 50% more.Also Solar Panels form only a part of the total Solar System Cost.The total cost of installation,equipment and wiring can cost upto Rs 30,000/Kilowatt.

GE is now looking to dethrone the No.1 Solar Energy Producer First Solar using its all round strengths.GE had invested in a Cadmium Tellurium Startup Prime Solar which is ramping up production.Note Cd-Te is the same technology which is used by First Solar.GE has said that it has managed to attain 15% efficiency on commercial glass.Don't know how much of it is true since First Solar only manages around 12% efficiency despite around 10 years of dedicated R&D.However if GE can even manage to get near to that level then it would surely give First Solar a run for its money.GE has also tied up with Japanese Solar Frontier to market its CIGs based modules.Note Solar Frontier or Showa Shell is building a massive 900 MW plant in Japan.This would make Frontier Solar one of the biggest Solar Players in the world.GE is offering an integrated solution comprising of modules,inverters,services and other BOS equipment to get a leg up on competition.

With most of the low hanging fruit of polysilicon costs already gone,the industry has to focus on efficiency to cut down on costs.Selective emitters,microinverters,DC-DC optimization and other technologies are already finding takers.A Number of microinverter companies like Tigo,Enphase Energy etc are tying up with global heavyweights like Suntech and Sunpower to increase their penetration and cut costs.National Semiconductor has also tied up with Suntech to integrate its products with Suntech Modules to improve efficiency and reliability.The Balance of Systems costs for Solar Panels and their Performance are not usually paid a lot of attention.But with every cent now making a big difference,these technology could make or break a company in this commoditizing industry.While the value addition and costs of these new products are still subject to market acceptance,its a major change for the industry.This is the next phase in the evolution of the solar energy industry as it looks to additional ways to cut costs and bring solar energy to grid parity.Look for M&A in this space as well since the industry is fragmented with a host of VC backed startups.

Saint Gobain like Semiconductor Giant TSMC is betting on Copper Indium Gallium Selenium (CIGs) Technology rather than the mainstream crystalline silicon technology.CIGs is getting the most significant investments these days compared to other thin film technology.Yesterday Ascent Solar (ASTI) got an IEC certification for its flexible modules which would enable it to target the mainstream rooftop market from niche applications earlier.Miasole has improved the efficiency and costs of it CIGs greatly while Nanosolar can't be counted out because of its strong backers.Solyndra however remains mostly in the shadows despite around $1 billion in private investment.Stion is another strong contender partnering with TSMC and also thinking of opening a plant in Taiwan on its own as well.Saint Gobain is already a big player in the solar market as it suppliers glass to a lot of solar companies for their modules.Getting into panel manufacturing will further allow it to get a foothold of this new potentially giant industry.Du Pont,Dow Chemicals,Corning all have considerable presence in the solar equipment market as well.
