Simply, you've no more but the following two alternative options only:

Opt.A. You select CIGS thin-film photovoltaic solar panels―the cheaper solution, low cost insta-llation, the last word of the advanced hi-tech, the solar cells of the future; less efficient ―with a sunlight to electricity conversion efficiency of 19.9 percent (20% is the certified lab result! How amazing!).

Opt.B. You select crystalline silicon cells―solar cell with a sunlight to electricity conversion efficiency of 24.2 percent... (Level of efficiency in lab) [more]. That's amazing considering the theoretical maximum is 28%. It is also topping out at about 25%. A new world record for large area silicon wafers achieved by our prospective supplier, and has been con-firmed by the U.S. Department of Energy's National Renewable Energy Lab (NREL). And get lower in cost each day.

"The choice is yours. Bur it's not an easy one. We can advise you both―about the best engineer facility selection based on many factors, including the investment strategy and the manner of project financing.

Our Californian partner is a pioneer and leading manufacturers of Copper Indium Gallium Selenide (CIGS) thin-film photovoltaic solar panels. Through a distinctive manufactu-ring process, they have established CIGS as one of the lowest-cost, highest efficiency thin-film solar panels in the world – thus advancing the extraordinary potential for harnessing solar power as a com-petitive, sustainable energy source. Unlike many competing solar energy technologies, CIGS uses no crystalline silicon to make cells. [Learn more]

Following the results of Chevron testing the solar technologies Traditional silicon-ba-sed materials are the standard right now, though research firm iSuppli expects the market for thin-film solar panels to more than double by 2013.

Multiple foundation options and a preassembled, modular design facilitate rapid deploy-ment. Requiring only half the land area to produce the same amount of energy as conventional dual-axis trackers, the T20 Tracker minimizes the environmental impact. Real-time, remote monitoring and control is enabled via the Supplier's Advanced Tracker Controller, and seamless integration with power plant SCADA systems ensures low-cost operation.
