[RE-wrenches] Volcanos, reduced solar production and kWh performance warranties

[Dan Fink]

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?"
