PowerFilm PowerShade Fixed Site Solar System Cost Reduction Plan.

摘要

Power film and its partners have developed a Generation II PowerShade which meets or exceeds the goals of this development contract, increasing power and improving the ROI of the power shade significantly while improving a number of the human factors. Comparing the Gen II 1.8 KW PowerShade to the equivalent power Gen I unit (Gen I Medium), The cost has been reduced from $38,000 to $28,000 or by 26.3%. This is as compared to the Threshold goal of 20% and Objective of 30%. Output power per unit area increased 36% from 2.04W/sq ft to 2.78W/sq ft compared to a Threshold goal of 10% and Objective of 20%. The Specific Power (KW/lb) increased 74% from 3.9W/lb to 6.8 W/lb. While the weight reduction per Watt was not a stated goal, it is an important metric for usability. Lifetime has been increased from 3 years to the objective of 10 years. When all these improvements are taken into account and the PowerShade is used in optimum conditions, the crossover point relative to diesel generators comes at approximately $3.61 cost for the diesel fuel. This would give the PowerShade a positive return on investment for a wide range of installations.
