Once you decide your house must use the more complicated forms of solar heating then it comes down to deciding whether to use that for heating your house or if solar PV makes more sense in your climate. Here's the PV power for various climates in the USA in December:http://www.nrel.gov/gis/images/map_p...er_dec2008.jpg

PV has a big advantage then because PV utilzes the higher wavelength photons. Think of the xray principle where the photons are such a short wavelength they can even penetrate solid objects. Ikea even is getting into the business in Britain utilizing PV panels that work on ultraviolet wavelengths that work well in cloudy places like Great Britain.

I leave it you to research if places like the Pacific Northwest might be good places for solar PV now with these new panels. I don't know.
