How we estimate

We size a system to offset roughly your full electricity usage, then price it at 2026 national averages (~$2.80 per watt installed). Note the 30% federal tax credit no longer applies to purchased home systems as of 2026 — so we show the real out-of-pocket cost. Production varies with your sun exposure, so we adjust output by region, and savings assume you offset about 90% of your bill. Real quotes vary — use this to budget and compare installer bids.
