New to plug-in solar?

Plug-in solar lets anyone generate free electricity — no roof, no permit, no contractor. A single panel on your balcony can meaningfully cut your bill, especially as rates keep rising.

What to Expect If This Passes

🔌

Up to 1200W, no permit

The bill as drafted would allow systems up to 1200W AC connected to a standard household outlet — no permit, no utility approval required.

⚡

No net metering

The bill does not include net metering for plug-in systems. Excess generation would not be credited. Self-consumption maximization is key.

🏠

Renters included

The bill does not restrict installation to homeowners. Renters would still need landlord consent, but no permanent installation is required.

ℹPanels typically last 25–30 years with a 25-year output warranty. Microinverters carry a 10–25 year warranty depending on brand. Battery modules degrade faster — expect 10–15 years before capacity drops below 80%. The 25-year savings figure above assumes the panel and inverter run for the full window; budget ~$200–$400 for an inverter swap around year 15 if needed.
