  • What certificates are needed to open rooftop solar energy

    What certificates are needed to open rooftop solar energy

    If you want to add a solar panel to your home, you need to file for a building or structural permit, an electrical permit, and a solar photovoltaic (PV) permit.


    FAQs about What certificates are needed to open rooftop solar energy

    Do you need a license to install rooftop solar panels?

    Some states, like Colorado and Idaho, allow homeowners to perform electrical work on their own homes without a license, but in most cases a permit is still required to install rooftop solar panels.

    Do you need a permit to install solar panels?

    Generally, local governments require a homeowner's solar installer/contractor to obtain a permit for rooftop panels before they can be installed. After the PV system is installed, a professional from the local government will inspect the new array to ensure all building, electrical, and safety codes have been followed.
