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.

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.

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.

Applied Materials which was the 800 lb Gorilla in the a-Si Thin Film Equipment raking in Billions of Dollars in Orders from established Solar Leaders like Q-Cells and Suntech also found itself in trouble.With its SunFab Division leading Millions of Dollars and fast losing its economic viability,AMAT was forced to conduct Euthanisia.Its customers like SunFilm,Moser Baer,Suntech also have pretty much shut down their factories writing off large investments.However Oerlikon is not giving up like AMAT

Although the global financial crisis has pushed governments to sharply cut aid to the renewable sector, it has had little effect on costs in the solar mirror power sector compared with the photovoltaic (PV) sector, which uses solar panels to generate power.

“We’ve see some reduction in prices, but nothing like in the PV sector. Costs per megawatt are between 4 and 5 million but they can reach up to six depending on the kind of power storage system you use,” Seage said.

Sector analysts put the average cost of CSP per megawatt at about 5 million euros before the global financial crisis, about six times more than for conventional gas-fired power generation.

The high cost of CSP makes it unlikely to be competitive with conventional energy until the next decade, and that also depends on reasonable charges for carbon dioxide emissions.

“We see CSP power becoming competitive between 2020 and 2030, depending on a country’s levels of radiation,” Seage said.
