GreenSun solar panels

Using jewel-toned plates, the solar concentrators capture from a wide spectrum of light. Even on a cloudy day, they'll produce electricity, although less than on a sunny day with direct light. They're even cheaper than traditional panels, since they don't use as much silicon as standard panels.
