1. Kerala Rooftop Solar Pricing & Subsidy Matrix (2026)
With high residential power tariffs reaching up to ₹9.40 per unit in the upper slabs, Kerala rooftop solar offers one of the fastest paybacks in India. Under the PM Surya Ghar Muft Bijli Yojana, homeowners across Kerala State Electricity Board (KSEB), the state's sole DISCOM can claim up to ₹78,000 in direct central subsidy:
| System Size | Gross Turnkey Cost | PM Surya Ghar Subsidy | Net Consumer Cost | Annual Bill Savings | Estimated Payback |
|---|---|---|---|---|---|
| 1 kW | ₹60,000 – ₹70,000 | ₹30,000 | ₹30,000 – ₹40,000 | ₹12,500 / year | 2.8 Years |
| 2 kW | ₹1,20,000 – ₹1,35,000 | ₹60,000 | ₹60,000 – ₹75,000 | ₹25,000 / year | 2.9 Years |
| 3 kW (Most Recommended) | ₹1,70,000 – ₹1,95,000 | ₹78,000 | ₹92,000 – ₹1,17,000 | ₹38,000 / year | 3.0 Years |
| 5 kW | ₹2,75,000 – ₹3,10,000 | ₹78,000 (Max Cap) | ₹1,97,000 – ₹2,32,000 | ₹65,000 / year | 3.3 Years |
| 10 kW | ₹5,10,000 – ₹5,70,000 | ₹78,000 (Max Cap) | ₹4,32,000 – ₹4,92,000 | ₹1,30,000 / year | 3.5 Years |
2. KSERC Net Metering Framework & Banking Rules
The Kerala Electricity Regulatory Commission (KSERC) administers net metering guidelines designed to maximize bill savings for residential rooftop owners:
- Sizing Up to Connected Load: Systems can be approved up to 100% of your sanctioned load (or contract demand). If your sanctioned load is 4 kW, you can install up to a 4 kW rooftop plant without paying infrastructure upgrade fees.
- Financial Year Settlement: Units fed back to the grid are banked every month. The banking cycle runs until March 31 of each financial year. Unutilized energy credits at the end of the year are settled by your utility at the commission-approved generic tariff (as per KSERC norms).
- Tiered Tariff Slashing: In Kerala, consumption over 300 units per month incurs highest-tier charges. By generating your own power, solar offsets your top-tier units first, saving you ₹8 to ₹9 on every kilowatt-hour generated.
