However construction costs are a major expense for solar power. Here is a partially completed panel that is being made with the least expense possible. Primarily because the photovoltiacs came from the liquidation auction of BP Solar.
Ultimately these will form an array of 9 panels for a power generating capacity of more than 3kW and a return of investment of about 25% to 30% a year. It is really hard to find an investment that pays better than this.
A rather interesting problem I have had to solve is that photovoltiacs have a thin surface coating that can be damaged by fingers and moisture. The solution I have found is to paint the face of the photovoltiacs with transparent glow in the dark paint. My experimental results show that this protects the surface coating without effecting performance in any noticable way and besides the green glow in the dark is fascinating. However I would not recomend this for direct weather exposure.
There will be more to come in the days ahead.
