Is your solar system actually performing?
The only independent benchmark for solar homeowners. We compare what your system produced against what physics says it should — using real weather data, not 30-year averages.

Looking Ahead
Next month, we expect your solar resource to be 97% of typical based on seasonal patterns. April is historically your system's 4th strongest month — expect production to increase as days get longer.
Why Solar Benchmark
PVWatts gives you a rough estimate. We give you a diagnosis.
Homeowners use PVWatts to manually check their solar each month. Here's why that's not enough.
We don't compare your January to 30-year averages.
We compare it to what the actual sun over your roof delivered.
