I put a review in 1 year ago that was positive now I can put in a better informed review from my experience of producing solar for a year Before I bought I asked about my 255 watt panels production raj Patel told me there tested in ideal controlled conditions and I should get that on good days in which I do , on perfect sunny cool days they max out at 271 watts better than expected after one year my electric bill is 9.19 a month and I have a 1665 kWh credit with the electric co This far exceeded my expectation after studying solar for 3 years my only regret is I didn't talk to Raj Patel and gogreensolar solar Sooner than I did They were great to work with and made it easy can't say enough good things about co and support
