## How Much Does Solar Panel Installation Cost in Kerala?##
Solar energy has become one of the smartest investments for Kerala homeowners and businesses. With rising KSEB tariffs and strong sunlight across the state, the question most people ask first is simple: what will it cost?
Here is a complete breakdown of solar installation costs in Kerala for 2026 — by system size, with and without subsidies.
## Solar Installation Cost by System Size in Kerala##
| System Size | Price Before Subsidy | MNRE Subsidy | Estimated Final Cost |
|---|---|---|---|
| 1 kW | ₹60,000 – ₹75,000 | ₹30,000 | ₹30,000 – ₹45,000 |
| 2 kW | ₹1,10,000 – ₹1,40,000 | ₹60,000 | ₹50,000 – ₹80,000 |
| 3 kW | ₹1,80,000 – ₹2,10,000 | ₹78,000 | ₹1,02,000 – ₹1,32,000 |
| 5 kW | ₹2,80,000 – ₹3,30,000 | ₹78,000 (capped at 3kW) | ₹2,02,000 – ₹2,52,000 |
| 10 kW | ₹5,00,000 – ₹6,00,000 | Not applicable (commercial) | ₹5,00,000 – ₹6,00,000 |
*Note: Subsidy figures are for residential on-grid systems under the PM Surya Ghar Muft Bijli Yojana. Subsidy is capped at 3kW capacity per household.*
## What's Included in the Installation Cost?##
A complete solar installation quote in Kerala typically includes:
- Solar panels (monocrystalline or bifacial)
- String inverter or microinverters
- Mounting structure (rooftop or ground)
- DC/AC wiring and protection devices
- Net metering application and KSEB synchronisation
- 5-year AMC (varies by vendor)
Always confirm what is included before signing any agreement.
## Additional Charges to Know##
- KSEB net metering connection fee: ₹3,000 – ₹8,000 (varies by sanctioned load)
- Net metering deposit: ₹500 – ₹2,000
- Structural assessment (if roof is old or RCC check required): ₹1,000 – ₹5,000
## Does Solar Save Money in Kerala?##
Yes — significantly. A 3kW system generates approximately 12–14 units per day in Kerala, saving ₹60,000 – ₹80,000 per year on electricity bills depending on your tariff slab. With MNRE subsidy, the typical payback period is 3.5 to 5 years, after which generation is virtually free for the remaining 20+ years.
## How to Get the Best Price##
Getting 2–3 quotes from MNRE-empanelled vendors is essential. Prices can vary by 15–20% for identical systems. Flarize connects you with verified solar installers in Kerala so you can compare quotes and choose confidently.
A 3kW solar system in Kerala typically costs ₹1.0–1.3 lakhs after the PM Surya Ghar subsidy and delivers full payback in under 5 years with KSEB net metering.
Eligibility
Do not pay more than 20% of the total project cost as advance before receiving the KSEB sanction letter and signed installation agreement.
