I've had a solar grid inter tie set up here in California for a number of years, so I have had a tad bit of experience. The cost can be somewhat deceptive. I have heard prices of $20,000 to $30,000 banded around. At installation there is a healthy rebate from the California Public Utility commission, many other states have similar set ups. Then there are tax credits for Federal. California recently dropped their state credits. Plus, usually even a small installation, while not bringing you down to zero cost electrically, does bring your peak into the lower tiers of cost. Out of pocket mine cost me about $6,000. And it is working great. No, I do not have to clean them off every month. My monthly electrical bill is about $25. I am now in the process of adding a wind turbine to the mix. So look at the entire mix, ie cost, rebates and credits, and effects on the bill. Just my 2 cents 73 Mike WA6ARA
Since Satellite design is heavy into Solar power, and I talk about that a lot, you may have heard me compare my Solar car to Solar panels on the roof of your house as not economical, I WAS WRONG. I was overlooking many recent changes in the environment:
- Solar panels (PV) are 1% of what they cost in 1970
- PV dropped 40% this year due to 2007 Energy Boom and 2009
economic bust 4) $5,000 to $20,000 tax and cash back incentives for YOU 5) Grid-tie systems operate at 95% efficiency compared to 70% of
