I was referring to the need (sales) of a battery bank to go along with that energy charging potential. The cost of the panels isn't squat compared to what the batteries and infrastructure needed to handle it is going to cost.
California now has hundreds of acres of privately owned co-generation and electrical kWh growth is flat lining. Hundreds and hundreds of acres MORE worth of rooftop panels are in the planning works stage and now utility companies are suggesting they will have to RAISE rates to remain viable energy entities.
Electrical power down "here" costs about .05 kWh for the first 150 kWh from there it tiers to near fifty cents per kWh on DAC rates. 500 kWh every TWO months is considered to be splurging.
I've seen RV's that consume more kWh per day than a 5 bedroom 4 bath house. Try living on SEVENTY FIVE kWh PER MONTH. I dare you.
The Chinese are now said to be producing seven and a quarter MILLION solar panels a MONTH. It used to be laughable their claim to shoot for producing A BILLION total panels by the end of 2015. Manchuria is going to be a vast toxic wasteland by then, raw materials are coming from Australia, and you are going to be reading headlines in the USA. MAJOR UTILITY COMPANIES FACING CHAPTER 13. FEDERAL FUND BAILOUTS URGENTLY NEEDED.
