What solar rebates, tax credits and other incentives are available in my area? Is my roof good for solar? What should I do before I get solar? And what the heck is a solar renewable energy credit, anyway?
It goes without saying that solar electric systems do well in sunny climates. All else equal, the more sun, the better. Regions that get the most sun, however, often come with a lot of dust, which can be a drag on solar panel efficiency. In the absence of rain showers -- which typically do a fine job at rinsing panels -- what's a solar energy system owner to do? A group of clever scientists, which yesterday presented a report at the National Meeting of the American Chemical Society, may have the answer:
