Wrenches,
PVWatts does not accurately predicate Unisolar and Sunpower module performance
because it uses a generic single crystal silicon solar module power temperature
coefficient (I think -0.4% per degree C). Does someone have the technical paper
that specifies PVWatts module temperature
It seems to be -0.5%/degC:
