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.
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.
