Evaluating Your Site For Solar Energy
There are two basic questions to answer to determine if solar can work well at your location: Does your location get enough sun? Do nearby obstacles (trees, buildings, etc.,) at your location block too much sun? The first question depends on how cloudy your weather is. Within the US, almost all locations get enough sun to successfully use solar energy, but some are better than others. This one page solar resources map gives a rough idea of how good the solar resource is in your area. More detailed month by month information on the sun available at US cities.
