Rooftop Solar Costs in India 2026: ₹50K–70K vs ₹35K–40K per kW
Compare real costs of traditional rooftop solar (₹50K-70K/kW) with digital solar (₹35K-40K/kW). Understand hidden costs and which gives better ROI.
Key Takeaways
Traditional rooftop solar costs ₹50K–70K/kW before subsidies, plus ongoing maintenance.
Digital solar costs ₹35K–40K/kW with zero maintenance fees — everything included.
Over 15 years, digital solar's total cost of ownership is 40–55% lower than traditional rooftop.
Traditional solar requires rooftop ownership, months of installation, and ongoing upkeep.
The lower digital solar price reflects commercial-scale efficiency, not inferior quality.
Traditional Rooftop: What ₹50K–70K Gets You
Solar panels: 40–50% of cost (mono-PERC or bifacial modules)
Inverter: 15–20% (DC to AC conversion)
Mounting + wiring: ~20% (structure, switchgear, meters)
Installation + approvals: Labour, DISCOM net metering (2–6 months)
Annual maintenance: ₹3,000–5,000/year (cleaning, repairs, inverter replacement at year 10)
After PM Surya Ghar subsidy (up to 40%), effective cost: ₹30K–50K/kW. But you need a rooftop and months of paperwork.
