Monthly generation ≈ kW × daily sun-hours × 30.4 × 0.78 performance factor. Monthly savings are capped at your monthly consumption valued at your selected tariff.
Does not estimate export credits, fixed charges, seasonality, exact bill slabs or taxes. This is an educational planning tool.
Approximate planning only; actual yield, bill offset, subsidy and payback may differ significantly. The 0.78 performance ratio is a modeling assumption.

Sunlight & shade
Location, tilt, orientation, seasonal cloud and shade all change real generation.
Your energy usage
The value of electricity self-consumed can differ from exported units. Your tariff structure matters.
Installed cost & subsidy
Actual cost and final eligibility decide net investment and payback.
