[QUOTE="Nesikep, post: 1213383, member: 9096"] Looking at the latest battery technology, just for the power storage, I'm going to take the Lithium Ion 18V Makita cordless drill battery, which costs about $100 I've found the average life of them to be about 100 charges. So working it out to KWh, it's 18V x 3AH * 100 charges = 5.4KWh, or about $.50 worth of electricity.. so just storing the power is costing 200x more than buying it.. A 100W solar panel generates less than $.01 electricity per hour of GOOD sunlight.. they cost about $100, so it takes 10,000 hours of sunlight to pay for that. (about 10 or 20 years) Now comes a good inverter for $500. Meanwhile for $20,000 and a bunch of work, you can set up a 20KW generator on a creek (you gotta find that) that runs 24 hours a day all year, so at $.10/kwh it's still generating $2 per hour, or $16,000/year..
