As an integrator providing turnkey PV systems of X kW, I\u2019m 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\u2019s been spewing since 1983, a volcano that could get a lot worse on any given day. I\u2019m leaning strongly against agreeing to any such clause. Way too bad a precedent to set. Way too much of a liability.</span></p> <p class="MsoNormal"><span style="color: rgb(31, 73, 125);"> </span></p> <p class="MsoNormal"><span style="color: rgb(31, 73, 125);">Anyone else had to deal with this bugger of a performance warranty demand?</span></p> <p class="MsoNormal"><span style="color: rgb(31, 73, 125);"> </span></p> <p class="MsoNormal"><span style="color: rgb(31, 73, 125);">Thanks,</span></p> <p class="MsoNormal"><span style="color: rgb(31, 73, 125);">marco</span></p> <p

With the normal trade winds, the vog (volcanic smoke + fog) gets blown south past the volcano, around the south tip of the island and <b><i>then back up</i></b> 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.
