What is the solar payback time?
Reviewed by SolvSolar · Last reviewed:
Rooftop solar typically pays back in 3–6 years in high-tariff, high-irradiance markets and 6–9 years in lower-irradiance ones. Commercial and industrial systems usually sit at the fast end because unit rates are higher and daytime load matches generation. Modules keep producing for 25 years or more, so most of the asset life is effectively free energy.
