The solar power panels cost in India ranges between ₹40,000 and ₹60,000 per kW without subsidy. A complete 1 kW rooftop system, including panels, inverter, and installation, typically costs between ₹45,000 and ₹80,000. Prices vary based on panel type (monocrystalline, polycrystalline, or bifacial), brand, system size, and location. Government subsidies can reduce costs for residential systems by 40–60%.
In India, solar energy has emerged as a highly affordable and sustainable energy source. As electricity prices rise, more homeowners are turning to solar power panels to save money and reduce carbon emissions.
But one of the most common questions people ask is, “How much do solar power panels cost in India?”
The answer depends on several factors: the type of solar panel, system size, installation method, and government subsidies. In this blog, we’ll break it all down so you can confidently plan your solar investment in 2025.
Understanding Solar Power Panels
A solar power panel converts sunlight into electricity through photovoltaic (PV) cells. Multiple panels form a solar system, which can power homes, offices, and factories.
The electricity generated is either
- Used directly (in grid-connected systems)
- Stored in batteries (in off-grid systems)
- Or both (in hybrid systems)

Average Solar Power Panels Cost in India (2025)
Here’s a breakdown of solar power panel costs in India based on system capacity:
| System Size (kW) | Cost Without Subsidy | Approx. Cost With Subsidy | Ideal For |
|---|---|---|---|
| 1 kW | ₹45,000 – ₹80,000 | ₹25,000 – ₹45,000 | Small homes |
| 2 kW | ₹90,000 – ₹160,000 | ₹55,000 – ₹95,000 | 2–3 BHK homes |
| 3 kW | ₹140,000 – ₹210,000 | ₹95,000 – ₹130,000 | Medium houses |
| 5 kW | ₹220,000 – ₹320,000 | ₹160,000 – ₹210,000 | Large homes |
| 10 kW+ | ₹400,000+ | Custom Pricing | Commercial use |
Note: Prices vary slightly across states due to installation charges, equipment quality, and region-specific subsidies.
Cost per Watt of Solar Power Panels
In 2025, the average cost of solar panels per watt in India is
- Monocrystalline panels: ₹35 – ₹45 per watt
- Polycrystalline panels: ₹25 – ₹32 per watt
- Thin-film panels: ₹20 – ₹28 per watt
- Bifacial or PERC panels: ₹40 – ₹50 per watt
If you’re researching [How Many Types of Solar Panels] or [Different Types of Solar Panels], you’ll find that monocrystalline panels are more efficient but slightly pricier, while polycrystalline panels are more affordable and ideal for spacious rooftops.
Key Factors Affecting Solar Power Panel Costs
a) System Size
Larger systems cost more upfront but have a lower cost per kW and deliver higher long-term savings.
b) Panel Type
- Monocrystalline: Highest efficiency (18–24%) and premium cost.
- Polycrystalline: Mid-range efficiency (15–18%) and cost.
- Thin-film: Budget-friendly but lower efficiency (10–13%).
c) Inverter and Mounting
The solar inverter converts DC to AC power and can add ₹15,000–₹25,000 to the total cost. Mounting structures, cables, and installation labor also influence pricing.
d) Location and Roof Type
Solar systems in metro cities or areas with high labor rates may cost slightly more. Similarly, complex rooftops require additional mounting.
e) Brand and Warranty
Top-quality brands often offer 25–30 years of performance warranty, ensuring long-term reliability.
Government Subsidy on Solar Panels in India (2025)
The PM Surya Ghar: Muft Bijli Yojana and the National Rooftop Solar Scheme (Phase II) offer generous subsidies to homeowners.
Residential Subsidy Breakdown:
- Up to 3 kW: 60% subsidy on benchmark cost
- Above 3 kW to 10 kW: 40% subsidy on benchmark cost
- Beyond 10 kW: No subsidy for additional capacity
Example:
If a 3 kW system costs ₹1.5 lakh, the subsidy covers about ₹60,000. You’ll pay only around ₹90,000.
These incentives make solar systems highly cost-effective. For businesses and industries, consult [Suppliers of Solar Panels] or [Solar Panel Suppliers] for updated commercial subsidies and net metering benefits.
Maintenance Cost of Solar Panels
Once installed, solar systems require minimal maintenance.
- Cleaning: Every 15–30 days to remove dust.
- Inspection: Twice a year to verify wiring and performance.
- Average yearly cost: ₹2,000–₹4,000.
(*Note: All costs mentioned above are estimates and can change with time.)
ROI and Payback Period
The return on investment (ROI) for solar panels in India is impressive. Most homeowners recover their investment within 4–6 years, while panels continue generating free electricity for over 25 years.
If your monthly electricity bill is ₹3,000, switching to solar can save up to ₹36,000 annually—making it one of the smartest investments you can make.
