St. Peters FAQ
How much solar production can I expect in St. Peters?
PVFig models St. Peters at ~1288 kWh per kW installed per year, derived from Missouri's NREL PVWatts v8 state value (1290 kWh/kW) adjusted for the city's latitude. This is a modeled estimate — a site-specific PVWatts run with your exact roof azimuth, tilt and shading will differ. Actual output also depends on panel quality and local weather.
What is the estimated solar payback in St. Peters?
At a typical 2.80/W installed cost and 12.8¢/kWh electricity, a 6 kW system in St. Peters has an estimated payback of about 16.1 years. That is a long payback — solar is hard to justify unless strong state incentives apply.
Does Missouri have net metering and a solar tax credit in 2026?
Missouri uses full-retail net metering. There is no state income tax credit for residential solar in 2026. The federal residential credit (Section 25D) expired Dec 31, 2025 and does not apply to 2026 installations.
