SuryaDrive

Charge your EV from the roof. Pay ₹0.50–₹0 per km.

India's first focused solar + EV savings calculator — grid costs ₹1–1.5/km; rooftop solar under PM Surya Ghar can drive that to near zero after payback.

Why solar EV charging matters now

PM Surya Ghar is live. Industry coverage from Heaven Green Energy and EVINDIA keeps landing on the same gap: no India-specific solar + EV tool in top search results — until this one.

  • Grid EV is cheap. Solar EV is cheaper.

    Home charging on DISCOM power usually lands around ₹1–1.5 per km. Rooftop solar brings effective cost to ₹0.50–₹0 per km once generation offsets your units.

  • Net metering does the night shift

    Panels export by day; you charge the car at night. Banked units cancel the EV draw — the practical path to near-zero running cost without expensive off-grid batteries.

  • Size beyond the 3 kW subsidy cap

    Keep the ₹78,000 central grant, then add 2–3 kW for the car. Most EV households land in the 5–7 kW sweet spot for home + commute.

PM Surya Ghar central subsidy

Residential rooftop systems get a direct bank transfer after DISCOM commissioning. Cap is ₹78,000 — the same whether you install 3 kW or 10 kW.

System size Central subsidy
1 kW ₹30,000
2 kW ₹60,000
3 kW and above ₹78,000 (capped)

Estimates use ~₹60,000 per kW all-in rooftop cost, 0.8 performance ratio, and 25-year levelized solar cost during payback. Actual tariffs, irradiance, and vendor quotes vary by state and DISCOM.
