Low Light Solar Panels?

[Giantsbane]

Are there solar panels that are effective in limited light scenarios? We only get about 6 hours of daylight (on a good day!) beyond the wall. It will only get worse, winter is coming.

Yeah but not really worth it as they will take years to recover initial outlay. best to combine these with other alternative energy solutions for a better return.
