Will my Delhi home's wiring handle 10 kW solar?

10 kW requires a 3-phase connection. Single-phase connections need an upgrade through BSES/TPDDL first — typically 3-4 weeks and ₹15-25k.

How much subsidy do I get on 10 kW solar in Delhi?

PM Surya Ghar caps at ₹78,000 regardless of system size above 3 kW. Delhi adds ₹30,000. Total: ₹1,08,000 — same as 3 kW.

What roof area do I need for 10 kW?

Around 650 sqft of shadow-free roof for 18 × 580 Wp panels. Elevated structures help if you want to keep the area underneath usable.

10 kW rooftop solar system installed in Delhi

10 kW in Delhi means you're past every residential sanctioned-load default and into a 3-phase connection. Eighteen 580 Wp panels need ~650 sqft of clean roof, which is realistic on independent builder floors in South/West Delhi but not on standard 100 sq yd plots. Net metering still applies 1:1 up to sanctioned load under DERC rules, so the payback math holds. PM Surya Ghar caps at ₹78,000 — the marginal panels above 3 kW are unsubsidised, but cost-per-kW drops at this scale so you're still 7-9% better off per kW than a 3 kW system.
