I'm starting to install a ground mount solar array in Pennsylvania and I'm really scratching my head over the permitting process. I spoke to my township supervisor, and they told me I don't need any permits for my solar array. However, my electrical utility mentioned that I must get an inspection from a PA-certified electrical code inspector before I can connect my system. When I contacted a local inspection service (Bureau Veritas), they insisted that I do need permits, citing the 2018 IRC and 2017 NEC codes available on the ICC's website. I'm really confused about what the rules are—do I actually need permits, and if so, who is requiring them?

I totally get your confusion! In my state, utilities need to inspect any grid-tied setup since they control the permission to operate (PTO). If you're within city limits, you typically need a permit and an inspection. But if you’re outside city limits, often no permit is needed. It's best to check your local rules to be sure!
From what you described, it seems like you do need a permit unless you can find a way to get a PA-approved inspection without one. Utilities usually require some level of inspection to ensure everything is safe when connecting to the grid.
It sounds like whether you need permits depends on how you plan to set up your solar array. If you're going for a grid-tied system, then yes, the utility will definitely need to inspect and approve it. If you're thinking of going off-grid, you might be in the clear and not need any permits at all.
