Residential solar calculator
An order-of-magnitude estimate of the photovoltaic power and storage suited to your home — five inputs, instant on-screen result.
This tool provides an order-of-magnitude sizing estimate, for public pre-diagnostic use only. It does not replace a feasibility study (actual yield, shading, roof constraints, applicable ANRE regime) carried out by department D3.
Your indicative sizing
—
kWc of recommended photovoltaic power
—
kWh/year — estimated annual production
—
% — actual consumption coverage rate
—
kWh — suggested storage (BESS) capacity
—
MAD — indicative investment (PV + storage)
—
MAD/year — estimated annual savings (electricity + avoided fuel)
—
years — estimated payback period
—
MAD/kWh — estimated cost per kWh of solar produced (over 15 years, excluding maintenance)
