Verified Performance

Is your solar system generating what it should?

Your installer's app tells you what your system made — but not whether that's good. We're neutral, so we'll compare your actual generation against what a healthy system of your size should produce, and tell you plainly if something looks off.

Which state is your system in?

We use your state's average solar yield to work out what a healthy system of your size should generate.

How big is your system?

The installed size in kilowatts-peak (kWp) — it's on your installation invoice or net-metering agreement.

kWp
What has it actually generated?

Enter the units (kWh) generated in one or more recent months — from your inverter's app/display, or your net-metering bill. Two or three months gives a far more reliable read than one.
