Rooftop Solar Estimate
See what your own roof could do with solar — panels, yearly power, and a plain, no-sales-pitch estimate of the savings. No sign-up, nobody calls you.
Solar gets sold hard in Southern California — door-knockers, robocalls, pressure to sign tonight. This is the opposite. Type your address and see what your own roof could actually do, read from Google's aerial imagery and a sun model, with every number behind the savings shown in plain sight. No sign-up, no salesperson, and nobody calls you.
What goes into the numbers
Your electricity rate — Southern California Edison
Southern California Edison powers Westminster. Its average home rate is about 34 cents a kilowatt-hour in 2026 — but you pay more in the late-afternoon peak (around 58 cents from 4 to 9pm on the common time-of-use plan) and less off-peak. We use the average; your own rate depends on your plan and how much you use. Check your own rate.
What you’re paid for extra power
Since California's Net Billing Tariff (NEM 3.0, from April 2023), SCE pays the full retail rate only for the solar power you use yourself. Power you send back to the grid earns a much lower export credit — on average around a quarter of the retail rate, and the exact amount changes hour to hour. That is why the savings here are a best case, and why a battery, which lets you use more of your own solar, can change the math.
Incentives
There is no longer a federal tax credit for a solar system you buy in 2026. The 30% Residential Clean Energy Credit ended for systems completed after December 31, 2025, under the 2025 federal budget law. If anyone still quotes you a 30% federal credit on a purchase this year, treat it as a warning sign. (A lease or PPA is taxed differently — the company that owns the panels may still claim a credit and fold some of it into your price.)
