If you think providing a PV energy output warranty is scary, imagine
trying to provide one for a small wind turbine!
Fortunately, the Small Wind Certification Council will be giving us
wrenches a big boost over the next few years as their turbine
certification program moves forward.
At least turbines will be certified that they perform up to their
claims, and poor siting issues will become more apparent.
And when your customer demands a small rooftop VAWT in lieu of half your
planned PV array, you can ask "is that turbine certified?"

Bill,
If, a big*/ IF/*, I were to agree to a performance warranty, I would
want to agree to an annual production figure 90 or less percent of the
estimated output along with a bunch of caveats, like the one you
suggest, to render any performance warranty relatively toothless.
Otherwise, I see it as way too big of a liability and a really bad
precedent.
