Switching to solar isn’t just a trend in Kerala, it’s a smart financial move. With electricity prices rising, a 3kW solar plant is the “sweet spot” for most families, offering a perfect balance between high energy generation and the maximum possible government subsidy.
If you are tired of those high bimonthly bills, here is everything you need to know about the 3kW solar panel price in Kerala 2026 and how to get your subsidy.
Overview of 3kW Solar Panels
A 3kW solar system is the most popular choice for mid-sized Kerala homes (typically 2-3 BHK). It is powerful enough to run lights, fans, a refrigerator, a washing machine, and even one or two air conditioners intermittently.
- Generation: Expect roughly 12-15 units of electricity per day, or about 360-450 units per month.
- Space Needed: You will need approximately 250-300 square feet of shadow-free rooftop space.
- Setup: Most residential systems in Kerala are on-grid, meaning they are connected to the KSEB grid and use net metering to track your energy credits.
Current Market Price of 3kW Solar Panels in 2026
In 2026, the cost of solar equipment has stabilized, making it more accessible than ever. Before any government help, a high-quality 3kW system typically ranges from ₹1,89,000 to ₹2,20,000.
| Component | Estimated Cost (3kW System) |
| Solar Panels (High-efficiency Mono PERC/TOPCon) | ₹75,000 – ₹95,000 |
| Solar Inverter (On-grid/String) | ₹20,000 – ₹45,000 |
| Mounting Structure & Accessories | ₹12,000 – ₹22,000 |
| Installation, Cables & Net Metering Fees | ₹20,000 – ₹40,000 |
| Total Price (Before Subsidy) | ₹1.89 Lakh – ₹2.20 Lakh |
Factors Affecting the Price of Solar Panels
Not all quotes you receive will be identical. The final price depends on:
- Panel Technology: Newer N-Type TOPCon or Bifacial panels cost more but generate more power in low light (perfect for Kerala’s monsoons).
- Mounting Structure: Since Kerala faces heavy rains and winds, using high-quality, corrosion-resistant galvanized iron (GI) structures is essential and may add to the cost.
- Inverter Brand: Premium brands with better warranties (like Deye or Growatt) will slightly increase the initial investment.
- Roof Type: Installing on a flat concrete roof is generally cheaper than custom structures for slanted or tiled roofs.
Government Subsidies for Solar Energy in Kerala
The primary incentive for Kerala homeowners is the PM Surya Ghar: Muft Bijli Yojana. This central government scheme provides a fixed subsidy that is credited directly to your bank account.
For a 3kW system, the subsidy is capped at a generous ₹78,000.
The “After-Subsidy” Math
- Market Price: ~₹2,00,000
- Government Subsidy: – ₹78,000
- Your Net Investment: ₹1,22,000
Eligibility Criteria for Government Subsidies
To qualify for the ₹78,000 subsidy in Kerala, you must meet these requirements:
- Domestic Consumer: The subsidy is strictly for residential properties, not commercial or industrial ones.
- Ownership: You must be an Indian citizen and own the house where the panels are installed.
- Electricity Connection: You need a valid electricity connection with KSEB (or your local DISCOM) in your name.
- Approved Vendor: The system must be installed by a vendor empanelled with the National Portal/ANERT.
- On-Grid System: Only grid-connected systems with net metering are eligible for this subsidy.
How to Apply for Solar Panel Subsidies in Kerala
The process is now fully digital and transparent. Here is your step-by-step roadmap:
- Register: Visit the National Portal for Rooftop Solar (pmsuryaghar.gov.in) and register using your KSEB consumer number and mobile.
- Feasibility Approval: Submit your application online. KSEB will check if your local transformer can handle the extra solar power and give “Feasibility Approval”.
- Select a Vendor: Choose an empanelled vendor from the portal list to handle the installation.
- Installation & Net Metering: Once installed, your vendor will help you apply for a net meter. KSEB officials will inspect the site and commission the system.
- Subsidy Claim: Upload your bank details and a cancelled cheque on the portal. The subsidy is usually transferred within 30 days of commissioning.
Benefits of Installing 3kW Solar Panels
- Huge Savings: You can save between ₹4,700 and ₹5,200 on every bimonthly KSEB bill.
- Quick Payback: With the subsidy, most Kerala families recover their investment in just 2 to 4 years.
- Energy Independence: You are protected from future electricity price hikes.
- Eco-Friendly: A 3kW system significantly reduces your carbon footprint, contributing to a greener Kerala.
Common Myths About Solar Panels in Kerala
- “They don’t work in the monsoon”: While generation is lower on rainy days, solar panels still produce power from ambient light. Modern panels are designed to handle overcast conditions.
- “High maintenance”: Solar panels have no moving parts. A simple cleaning with water once or twice a month is usually all they need.
- “They will damage my roof”: Professional installers use waterproof chemical anchoring to ensure your roof remains leak-proof.
Conclusion and Future Outlook for Solar Energy in Kerala
By 2026, Kerala has emerged as a leader in rooftop solar adoption. With the PM Surya Ghar scheme aiming to power millions of homes, the infrastructure and support systems in the state are stronger than ever. Investing in a 3kW system today means paying roughly ₹1.22 Lakh (after subsidy) for a system that will provide free electricity for the next 25 years. It’s not just an appliance; it’s a long-term asset for your home.
