For full details please read my blog post: www.thediyworld.com/blog/?p=1417 Ok, a full day and a night of testing the solar powered air conditioning system proves that it can and does work. My stuff costs about $2,000. You may pay a bit more depending on where you look. In this video I show you where to get solar panels as low as 50 cents per watt. Yes, it is true. You may find that after shipping its $1 per watt. That is cheap and good. Its still cheaper than the full retails of $5 to $10 per watt. My solar panels are off craigslist at 50 cents per watt. 800 watts = $400 My charge controller retails for about 500 The batteries are about 100 each = $600 The inverter retails for about 500 but you can get a tiger claw pure sine wave inverter off amazon for about $179. I read lots of good reviews about them. Check craigslist for second hand or discounted, scratched or dented solar panels. Check sunelec.com for low priced solar panels. The charge controller is an mppt type tristar controller from www.solar-electric.com/
