Monthly units take priority. When units are not entered, bill ÷ tariff is used for an indicative consumption estimate.
From your electricity bill to a practical estimate
We separate consumption, location, roof feasibility and financial assumptions instead of giving one generic number.
Consumption
Monthly units or bill are converted into annual energy demand.
Location
State and city/district are used for the indicative yield assumption.
Roof fit
Panel requirement is compared with practical planning area.
Finance
Cost, savings, CFA and simple payback are displayed separately.
