Solar PV Energy Yield Calculator

Estimate daily, monthly and annual PV energy from installed kWp, peak sun hours and performance ratio.

How it works

Estimate daily, monthly and annual PV energy from installed kWp, peak sun hours and performance ratio.

Formula:
Daily energy ≈ kWp × peak-sun-hours × performance ratio.

Before you use the result: Do not use simplified thermal or moisture estimates as a substitute for a complete building-physics assessment.

Practical use

Use verified material data and project geometry. Treat results as planning estimates and compare them with the energy/thermal requirements that apply to the project.

Keep units consistent with the source information.
Use project-specific densities, pack sizes and coverage rates where provided.
Round purchasing quantities to supplier packaging and delivery rules.
