Solar savings estimator

See the commercial case before detailed design.

Use editable planning assumptions to estimate system size, annual generation, savings and simple payback. Final results still require a site survey and engineering review.

Planning assumptions are editable and are not utility quotations.

The usable roof area supports the preliminary size.

Estimate only. Final sizing depends on hourly loads, shading, equipment efficiency, battery strategy, local tariffs, taxes, installation scope and applicable standards.
