timely issue that I\u2019m dealing with right now with PV Power Purchase
Providers.&nbsp; 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.&nbsp; I am EXTREMELY uncomfortable to any such clause in any
contract that I would sign.&nbsp; I have strong confidence in my PV design
capabilities &nbsp;and engineering support and in my professional crew to
install a top-quality PV system.&nbsp; 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.&nbsp; 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.&nbsp; I\u2019m leaning strongly against agreeing to any such
clause.&nbsp; Way too bad a precedent to set.&nbsp; Way too much of a liability.<o:p></o:p></span></p>
