Solar Panel Price in India 2026: 1kW, 2kW, 3kW, 5kW & 10kW Cost

Short answer: In India in 2026, rooftop solar costs roughly ₹60,000–₹70,000 per kW before subsidy for a quality on-grid system. After the PM Surya Ghar subsidy, a 3 kW system (the most popular home size) lands near ₹1.0–1.3 lakh net and pays back in about 4 years. Here’s the full price list by size.

Solar panel price list in India (2026)

System	Before subsidy	Subsidy	Net cost	Daily units	Suitable for
1 kW	₹60,000–70,000	₹30,000	₹30,000–40,000	~4	small home
2 kW	₹1.1–1.3 lakh	₹60,000	₹50,000–70,000	~8	2 BHK
3 kW	₹1.7–2.1 lakh	₹78,000	₹1.0–1.3 lakh	~12	typical home
5 kW	₹2.8–3.4 lakh	₹78,000	₹2.0–2.6 lakh	~20	large home + AC
10 kW	₹5.5–6.5 lakh	₹78,000*	₹4.7–5.7 lakh	~40	villa / small commercial

*Residential subsidy caps at ₹78,000 above 3 kW. Prices vary by panel type (mono vs TOPCon vs bifacial), inverter brand, and roof.

What decides the price

• Panel technology — mono-PERC is the budget standard; TOPCon/bifacial cost more but generate more.
• Inverter — a quality string or micro-inverter is where cheap quotes cut corners.
• Mounting structure — must survive local weather; under-spec’d structures fail early.
• Balance of system — cabling, earthing, lightning + surge protection.
• Site complexity — RCC vs tin-shed vs elevated, extra civil work.

Which size should you buy?

Size to your actual electricity consumption, not your budget. A rough guide: every 1 kW generates ~4 units/day in most of India. Match your monthly bill:

• ₹1,000–1,500 bill → 1–2 kW
• ₹2,500–3,500 bill → 3 kW (also earns the full subsidy)
• ₹5,000+ bill or heavy AC → 5 kW+

Savings and payback

A 3 kW system generating ~400 units/month saves most homes ₹2,500–3,500/month — a payback of about 4 years, then 20+ years of near-free power under the 25-year panel warranty.

Common mistakes

1. Sizing by budget, not load — undersizing leaves you still paying big grid bills.
2. Cheapest quote wins — the saving hides in the inverter, structure, or cabling.
3. Ignoring the subsidy step — money left on the table.
4. No written bill of materials — you can’t verify what you’re buying.
