Estimation Tool
Solar Savings Calculator
This calculator produces an indicative estimate based on standard assumptions for irradiance, module performance, and system losses. Actual system size, generation and payback depend on your specific site, load pattern, tariff, roof or land condition, applicable subsidies and financing choice. A site visit is required for a binding commercial proposal. Nothing on this page is a savings guarantee or financial advice.
How this estimate is calculated.
Uses standard regional irradiance data and typical solar performance assumptions to provide a first-order estimate for planning — not a substitute for a site-specific engineering study.
-
Regional Irradiance
Standard regional solar-resource data for the project location.
-
Module Performance Assumptions
Typical module output and degradation over the plant design life.
-
System
Standard system losses — wiring, inverter conversion, soiling and temperature.
-
Financial Model
Tariff offset against indicative system cost to give a first-order payback.
Model outputs are indicative only. Not financial advice. Actual project economics depend on your site, tariff and financing structure.
