This thread brings up a very timely issue that I’m dealing with right now with PV Power Purchase Providers. As an integrator providing turnkey PV systems of X kW, I’m being asked to contractually agree to a minimum performance warranty for said PV systems. I am EXTREMELY uncomfortable to any such clause in any contract that I would sign. I have strong confidence in my PV design capabilities and engineering support and in my professional crew to install a top-quality PV system. I have a lot less confidence in an inverter manufacturer being able to get to a site on a Hawaiian island in the middle of the Pacific in a super timely fashion as the lost PV kWhs rack up. And as I mentioned in a previous post today, we have an active volcano here that’s been spewing since 1983, a volcano that could get a lot worse on any given day. I’m leaning strongly against agreeing to any such clause. Way too bad a precedent to set. Way too much of a liability.
Anyone else had to deal with this bugger of a performance warranty demand? Thanks, marco ProVision Solar Marco: Our production schedule has been in tatters - lowered by perhaps 30% because of the rain.... can't plan, can't do. Then I pay overtime on good days to (try to) catch up. We have a number of systems online and I had not thought to actually review and compare from this year to last. I'll let ya know. We'll get a call like - "My bill is higher than last year (edison has a bar graph of monthly consumption for the past 13 months) and I'd like you to look at my system" or My meter is not going backwards, should I call edison?" The weather is so consistently wet this winter (think Hilo) that we usually just need to ask- "Been outside lately?" But everywhere is so green and the desert bloom is outrageous......... http://www.desertusa.com/wildflo/ca.html Pat Redgate Ameco Solar In a message dated 4/25/2010 12:24:53 P.M.

On the Big Island of Hawaii, we’ve had a very active volcano doing its thing since 1983. With the normal trade winds, the vog (volcanic smoke + fog) gets blown south past the volcano, around the south tip of the island and then back up along the west side of the island. Which means that Kona-side residents can be in a yucky vog zone for days and sometimes longer. Think L.A. on a smoggy summer day. And as far as percentage decrease in solar output, I really have little accurate clue. Marco ProVision Solar Kicked out butts, in fact.
