What an 800W kit would do in Utah
Assuming ~5.5 peak sun hours per day and typical system losses, a standard two-panel 800W plug-in kit in Utah produces about 1237 kWh per year. At the state’s average residential rate of 11.3¢/kWh, that’s roughly $119 per year off your electric bill if you self-consume most of it. A typical 800W kit costs $500–$1,200, so simple payback lands in the 6–10 year range. Run your own numbers →
What this means for renters and condo owners
Plug-in solar was legalized in Utah precisely for people who can’t put panels on a roof: renters, condo owners and anyone with a sunny balcony, patio or backyard. Buy a certified kit under 1200W, plug it into a standard outlet, and it quietly offsets your daytime consumption. Get written landlord/HOA approval for mounting hardware on balconies.
FAQ
Is plug-in (balcony) solar legal in Utah in 2026?
Yes. Utah passed HB 340, allowing systems up to 1200W. Signed March 2025 — in effect since May 7, 2025.
How much can an 800W plug-in solar kit save in Utah?
With about 5.5 peak sun hours per day and residential electricity at roughly 11.3¢/kWh, an 800W kit produces around 1237 kWh per year — worth approximately $119 per year if you use most of that power yourself.
Do renters in Utah need an electrician to install plug-in solar?
No. The point of Utah’s law is that certified plug-in systems under 1200W plug into a standard outlet — no electrician, no rooftop permits. Renters should still get landlord approval for balcony mounting.
Does Utah pay for extra electricity a plug-in system exports?
Generally no — plug-in solar laws are built around self-consumption, not net metering. Any power you don’t use typically flows to the grid uncompensated, which is why sizing the system to your daytime usage matters.
