If You Install Solar Yourself, What Still Has to Go Through Permits and the Utility?
Summary
Doing the work yourself does not skip permitting or inspection. DOE says rooftop panels generally need a local permit before installation, an inspection by a local government official afterward, and then the utility connects the system to the grid. SolarAPP+, the online system that issues permits instantly, is open only to licensed contractors.
Where a DIY project differs
DOE describes permitting as something local governments generally require installers to obtain, with rules and fees that vary by jurisdiction. SolarAPP+ serves more than 350 jurisdictions and issues a permit on the spot for code-compliant applications, but registration requires business and city licenses.
On the utility side, DOE's Energy Saver tells buyers to contact the utility about grid-connection requirements before purchasing any part of the system. An interconnection agreement usually follows, with possible permitting fees, engineering and inspection fees, metering charges for a second meter, and stand-by charges.
Warranties can differ too. REC's Alpha Pure-RX carries a 20-year standard product warranty that becomes 25 years when an REC certified installer puts the panels in and registers them.
