There are different types of solar panels.
One type converts sunlight to electricity, at whatever efficiency--I think
they're up to 15-20% now?
The other type simply captures the sun's heat, w/ much higher efficiency
(theoretically near-100%) using stuff like "selective surfaces", which get
super-hot in the sun.
These, being hot, would not be affected by snow, and could proly provide
most of your winter heat--assuming enough sun.
The ideal array would then be some *ratio*
of solar electric to solar heat
square footage, which would vary with latitude--mostly solar electric in the
south, mostly solar heat in the north.
HD is now hawking solar electric panels, $25K-50K installed.
