Open EIA sourceWhy the rate matters
The calculator estimates bill savings from self-consumed solar at the selected residential rate. A higher rate can shorten payback, while a lower rate makes installed cost and export credit assumptions more important.
What to verify next
Utility plans, time-of-use pricing, net billing, fixed charges, and export credits can differ from a statewide average. Check your bill and utility tariff before treating a planning estimate as a quote.
