How much solar production can I expect in Lewisville?
PVFig models Lewisville at ~1396 kWh per kW installed per year, derived from Texas's NREL PVWatts v8 state value (1421 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 Lewisville?
At a typical 2.55/W installed cost and 16.1¢/kWh electricity, a 6 kW system in Lewisville has an estimated payback of about 13.2 years. That is a long payback — solar is hard to justify unless strong state incentives apply.
Does Texas have net metering and a solar tax credit in 2026?
