About our solar calculators
Rooftop solar is an investment decision, not a purchase decision — and it turns on four numbers: your consumption, your usable roof area, the subsidy you qualify for, and your local tariff. These calculators work those through transparently so you can compare an installer's quote against an independent estimate before signing.
