Short answer: No. Pennsylvania has no plug-in solar law. A bill, HB 1971, has sat in the House Energy committee since October 2025. Until one passes, a kit needs your utility's interconnection approval.
The bill waiting in committee
- HB 1971 was referred to the House Energy committee on October 28, 2025. The official page shows no votes.
- As written, it allows up to 1,200 W, certified by UL or an equivalent lab, with no interconnection application, fee, or prior notice, and no credit for power sent to the grid.
Sources: HB 1971. Read October 26, 2026.
What applies today
Pennsylvania's interconnection rules (52 Pa. Code, Chapter 75) cover "customer-generators with small generator facilities ... designed to operate in parallel with the electric distribution system." A plug-in kit is one. 52 Pa. Code § 75.31.
Many people plug kits in anyway. That doesn't make it allowed, and your utility could ask you to disconnect.
Renters and HOAs
- HB 1971 says nothing about landlords. A separate HOA solar-access bill, HB 1239, passed the House on July 1, 2026, and is in a Senate committee. HB 1239.

Already have solar on the roof?
Before you buy a plug-in kit, find out whether your house is already sending power to the grid at midday. If it is, a plug-in kit mostly adds to that export instead of cutting your bill. The WattHacker monitor shows your rooftop production live, panel by panel. It plugs into the SunPower or Enphase gateway you already own.
- Home use is shown too where your system was installed with consumption meters. Without them you see production only. Your utility's hourly usage download also shows export.
- A plug-in kit is a separate inverter. Your rooftop gateway will not count its production, so neither will we.
- Free to see your panel data, with no subscription. The monitor is a one-time purchase with a 30-day money-back guarantee.
