What this means for you

✓ What you can do

  • Apply for interconnection like any small generator (Level 1 certified inverter <=10 kW), typical fee $100.
  • Use portable panels with a power station, never connected to house wiring, with no permission at all.
  • Install conventional rooftop or ground-mount solar through the standard interconnection process.

✕ Not yet / not allowed

  • Plug a grid-tied kit into an outlet without an interconnection agreement; it can breach your service terms.
  • Expect a permit or wiring exemption; none exists without a law.
  • Count on HB 1971 this year: Referred House Energy 10/28/2025; no action; session ends 11/30/2026.

What the rules say

Pennsylvania's bipartisan HB 1971 sits in committee; PECO/PPL interconnection rules apply.

Before you plug in: Pennsylvania checklist

  1. The rule that applies is Pennsylvania Public Utility Commission's interconnection process: 52 Pa. Code Ch. 75 Subch. C.
  2. A plug-in kit falls in the smallest tier (Level 1 certified inverter <=10 kW). $100.
  3. Permits: UCC 2020 NEC (1/1/2026); municipal permits; lockable visible-break disconnect required (75.36).
  4. Only consider kits with a UL 1741-listed inverter (UL 3700 preferred); a non-listed inverter will not be approved anywhere.
  5. What exports are worth: Retail net metering <=50 kW; annual excess at price-to-compare.
  6. If approval is slow or costly, a portable panel and power station (never connected to house wiring) needs no permission.
  7. Watch HB 1971: Referred House Energy 10/28/2025; no action; session ends 11/30/2026.

Your utility's rules in Pennsylvania

No utility in Pennsylvania publishes a rule that specifically allows or bans outlet-connected generation, so the general interconnection agreement is what applies. Here is what the largest residential utilities say and require.
