Consider adding a "Force Majeure" clause to your contract to cover "Acts of God" and other aspects not under your control.
On the other hand, auto manufacturers evade this issue with "Your mileage may vary."

How is the situation of the reduced performance due to the volcano (or other "acts of God" or the like) approached in the Power Purchase contract? Perhaps this could be titled "Reduced Solar Production As a Result of Reduced Solar Input". TIA, Bill Loesch Solar 1 - Saint Louis Solar PS As I remember, the last time I bought a new vehicle, back in the Dark Ages, the auto manufacturer's warranty deferred to the tire maker's warranty (for tires), etc. Any similarity? ----- Original Message ----- From: Marco Mangelsdorf To: 'RE-wrenches' Sent: Sunday, April 25, 2010 10:02 PM Subject: [RE-wrenches] Volcanos,reduced solar production and kWh performance warranties 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?
