Solar Installation Cost in India 2026: Complete Price Breakdown

A complete solar installation in India costs ₹55–₹75 per watt all-inclusive before subsidy — or ₹60,000 for a 1kW system to ₹6,50,000 for 10kW. After the PM Surya Ghar central subsidy (up to ₹78,000 for 3kW), a popular 3kW residential system costs ₹1,15,000–₹1,40,000 out of pocket. This includes panels, inverter, mounting, wiring, labour, and DISCOM paperwork.

Labour cost varies based on several factors specific to your property:

• Roof type — Flat RCC roofs are simplest and cheapest. Sloped tile roofs need specialised clamps. Metal sheet roofs require specific fasteners. Each adds ₹2,000–₹5,000 per kW.
• Building height — Multi-storey buildings require more cable, additional safety equipment, and longer installation time. Expect 10–20% premium over single-storey.
• Roof condition — If the mounting area needs waterproofing repair or structural reinforcement, that is an additional cost before solar work begins.
• Shadow obstacles — Water tanks, parapet walls, or adjacent buildings requiring creative panel placement increase design and labour time.
• City tier — Metro cities (Delhi, Mumbai, Bangalore) have higher labour rates than Tier 2–3 cities. Difference can be 10–15%.

A pre-installation checklist helps identify these factors early so there are no surprises in the final quote.

A transparent installer will itemise everything. But if you are comparing quotes, check for these commonly excluded items:

1. GST (13.8%) — Composite supply of panels + inverter + installation attracts 13.8% GST. Some quotes show pre-GST pricing to appear cheaper.
2. Net metering fees — DISCOM application fees and bi-directional meter cost range from ₹2,000–₹8,000 depending on your state. Not always included.
3. Elevated mounting — If your roof is flat, standard tilt structures are included. But if you need elevated mounting (for parapet walls or waterproofing access), it costs extra.
4. Earthing and lightning arrestor — Basic earthing is standard. Full lightning protection for larger systems (5kW+) may cost ₹3,000–₹5,000 additional.
5. Cable length — Standard quotes assume the inverter is near the panels. If your meter room is far from the roof, additional DC/AC cabling adds ₹1,000–₹3,000.

Always ask: Is this quote all-inclusive with GST, net metering, and mounting for my specific roof type?

If the upfront cost is a barrier, several financing options make solar accessible:

• Solar loans — Banks like SBI, HDFC, and Canara Bank offer dedicated solar loans at 7–10% interest with tenures of 3–7 years.
• EMI plans — Many installers offer zero-cost or low-cost EMI through NBFC partnerships. Monthly payments of ₹2,000–₹5,000 for a 3kW system.
• Subsidy + loan combination — You can use PM Surya Ghar subsidy along with a bank loan. The subsidy reduces your loan principal once disbursed.
