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.
