With the government subsidy under PM Surya Ghar Yojana (up to 40% for systems up to 3kW), your actual solar panel price can be significantly lower than the figures above — see the subsidy section below for details.
Factors Affecting Solar Panel Price and 3kW System Cost
Some factors affect the cost of installing solar panel systems:
- Solar Panel Type – Monocrystalline panels are pricey but are more efficient
- Inverter Type – String inverters are cheaper, whereas microinverters do better.
- Battery Storage – Off-grid ones need batteries which further add to the cost.
- Installation Charges — A solar installation company in Tamil Nadu ensures that the system is installed correctly, but the cost is then passed on to the owner.
- Mounting Structure – Specialized mounting structures for rooftop installations would incur additional pricing.
- Wiring & Accessories – Quality components will ensure longevity, but this increases initial costs.
Government Incentives: Subsidies to Lower Your Solar Investment
Encouragement for solar installations is provided by the Indian Government, and some incentives are provided under diverse schemes. The Ministry of New and Renewable Energy (MNRE) continues to aid such projects for installing solar systems in residential buildings:
- Residential Projects Subsidy: 40% or up to 3kW.
- Subsidies by the State: Additional benefits may be offered to residential homeowners switching to solar.
- Net Metering Benefits: There could be credits for feeding excess Solar Power to the grid.
Enroll with a solar installation company in Tamil Nadu for guidance on applying for subsidies and reducing the overall investment.

| Component | Estimated Price Range |

| Mounting Structure and Accessories | ₹10,000 – ₹30,000 |
| Installation and Labor | ₹20,000 – ₹50,000 |

On-Grid vs. Off-Grid Solar: Which Option is Right for You?
The two types of solar systems that a homeowner must choose between would be:
- On-Grid Systems: Connected to the local electricity grid, with excess energy being sold back through net metering. Cheaper systems for locations found in urban areas.
- Off-grid systems: Work independently of the grid and rely on battery storage; thus, they become very expensive on battery accounts for remote locations.
- Consulting a solar installation company in Tamil Nadu like ours can help you determine which system best suits your needs.
Estimating the Long-Term Savings and ROI of Your Solar System
Investing in a solar system is not only about upfront costs but also about long-term savings. A 3kW solar panel system would reduce the electricity bill by ₹2k-4k a month, depending on the panel output. Therefore, over 25 years, homeowners could save ₹10-12 lakh in energy costs!
The normal payback period for a 3kW solar plant in India is 4-6 years, providing about 20 years of free electricity.
Factors to consider before buying a solar panel system:
- Your Energy Needs – Study your average consumption of electricity.
- Available Roof Space – See if there fits one 3kW system.
- Budget and Finance – This shows you the way to exploring subsidies, loans, and EMI.
- Professional Installation – Hire a good solar installation company in Tamil Nadu.
