The fact that solar circuits can be used to generate electricity and power electric circuits as well as store electricity is a result of transistor technology just as the computer. The cost of producing these solar cells and arrays has dropped from tens of thousands of dollars 30 years ago to a few dollars today. The technology is advancing just as computer technology has advanced in the last few decades. We are also doing a cash flow as well as energy flow study of the solar structure.
