What permitting do I need?

In most cases, you will need a simple building permit issued by the city or county where you live. In some areas, especially on the East Coast, you will be issued a combined building and electrical permit for your solar installation. As more U.S. homeowners switch to solar energy, a few things might happen. On one hand, delays might occur simply because there’s a bigger backlog of applications. The good news is that with more demand, the process should become more streamlined and efficient.
