That is correct, the data shown in post #26 don't hold true for PA, due to the much lower solar energy levels there, solar cell performance will be much lower than the national average and lower than show in my table. (source)
"And the pricing of the panel, listed at $699, can be much less if you are a careful shopper."

Correct me if I'm wrong, but the losses due to the angle of the sun can be negated pretty simply by tilting the solar panel up, can't they? I can't think of any good reason to have all these solar panels installed perfectly horizontal.
OTOH, the more northerly areas tend to have a lot more cloud cover, and snow on the panels will certainly negate their usefulness, although if they have a slick surface and the panels are tilted up at 45 degrees or more, I suspect most snow might just slide right off.
