Yes, most solar panel installations require permits. Whether you're installing rooftop panels or a ground-mounted system, local building departments typically require permits to ensure safety, code compliance, and proper grid connection. However, there are specific exceptions and variations. . These tools are great for getting started, but make sure to work with a solar installer for a custom estimate of how much power your solar energy system is likely to generate. For its analyses, NREL uses an average system size of 7. 15 kilowatts direct-current with a 3-11 kilowatt range. However, any electrical connections to the power grid must typically be completed by a licensed electrician.
