    How we estimate

    The maths behind the numbers

    Simple, transparent assumptions. Your site survey replaces them with real measurements.

    Your units

    Monthly bill ÷ average tariff (₹7.5 per unit) gives your monthly units.

    System size

    Units ÷ (4 units per kW per day × 30), rounded up to the nearest 0.5 kW.

    Saving and subsidy

    Saving = units covered by solar × tariff. Subsidy follows the PM Surya Ghar slabs for homes.
