Interesting. Germany has only slightly fewer hours of sunlight per day than Newark NJ. Both considerably more than Seattle. (My hometown)

This doesn't really answer my question on ROI. Just like I don't accept the 'clean coal' clowns arguments on cost based on subsidies they receive, I am interested in the actual ROI for renewables.

Solar THERMAL seems to be better. Wind seems to be better.
Why the focus on PV to the point they under-budgeted and have to halt the subsidies? That tells me the subsidies were not in line with ROI, and should be spread among other generation sources.

I don't like anecdotes, but the thing I wake up to every morning, is the neighbor across the street. Again, I live in Seattle, so, the hours of daylight proposition is slightly worse, but the neighbor has lost his ASS on his PV install. Even with subsidies. (Granted, his is primarily competing with the cost of hydro, not coal or nuclear, where the value proposition of PV would be somewhat better)

He would have been money ahead installing his solar thermal kit, and been done with it. Adding the PV stuff was just a horrible mistake. If the panels don't last longer than 40 years, he'll never recoup his costs, and that was his expectation going into it. To say nothing of decaying inverters, which one can reasonably expect to happen on decades-long timelines.

No matter how I look at it, Rooftop PV just never seems like the winner to me, at these latitudes. There are better renewables.

Closer to the equator? Want to link power generation to cooling needs? By all means, rock out with your PV panels out.
