Solar panels (Photovoltaics) are a clean and environmentally safe means of harnessing energy produced by the sun, and converting it into electricity. These panels are typically made of crystalline silicon, but the highest quality panels are constructed of solid silicon ingot. Solar panels on the market that use silicon that is not cut from solid silicon ingots tend to offer lower efficiencies, poorer tolerances or lesser warranties. That is why at The Solar Supply Store you won’t find solar panels made of anything but the highest quality material and by the most respected solar panel manufacturers in the business.
