1. Karnataka Rooftop Solar Pricing & Subsidy Matrix (2026)
Governed by Karnataka Electricity Regulatory Commission (KERC) regulations and the PM Surya Ghar Muft Bijli Yojana, Karnataka homeowners can wipe out high commercial and residential slab bills across BESCOM, MESCOM, and HESCOM. Here is the 2026 cost matrix:
| System Size | Gross Turnkey Cost | PM Surya Ghar Subsidy | Net Consumer Cost | Annual Bill Savings | Estimated Payback |
|---|---|---|---|---|---|
| 1 kW | ₹58,000 – ₹68,000 | ₹30,000 | ₹28,000 – ₹38,000 | ₹11,000 / year | 2.9 Years |
| 2 kW | ₹1,15,000 – ₹1,28,000 | ₹60,000 | ₹55,000 – ₹68,000 | ₹22,000 / year | 3.0 Years |
| 3 kW (Most Popular) | ₹1,65,000 – ₹1,85,000 | ₹78,000 | ₹87,000 – ₹1,07,000 | ₹33,000 / year | 3.1 Years |
| 5 kW | ₹2,60,000 – ₹2,90,000 | ₹78,000 (Capped) | ₹1,82,000 – ₹2,12,000 | ₹55,000 / year | 3.5 Years |
| 10 kW | ₹4,80,000 – ₹5,40,000 | ₹78,000 (Capped) | ₹4,02,000 – ₹4,62,000 | ₹1,10,000 / year | 3.8 Years |
2. KERC Net Metering Policy & BESCOM Banking Cycle
Karnataka operates under progressive KERC rooftop regulations that allow domestic consumers to offset their retail electricity bills at the full slab rate:
- 100% Load Feasibility: You can install rooftop solar up to 100% of your sanctioned connected load without requiring special substation transformer augmentation approvals.
- Annual Banking Period: Energy banking operates from April 1 to March 31. Any surplus units left over at the end of the year are settled at the average cost of power purchase.
- Elimination of Gruha Jyothi Tariff Spikes: For families consuming more than 200 units who do not qualify for free power subsidies, rooftop solar brings monthly electricity bills down to the mandatory fixed meter charge.
3. Regional ESCOM Coverage Across Karnataka
Karnataka's power distribution is split between five regional electricity supply companies:
⚡ BESCOM (Bengaluru & Surrounds)
Serves Bengaluru Urban, Rural, Tumakuru, and Kolar. Handles the highest volume of tech-park villas and gated community rooftop solar installations with online digital meter approval.
⚡ MESCOM (Coastal & Malnad)
Serves Mangaluru, Udupi, and Shivamogga. Requires corrosion-resistant anodized aluminum mounting hardware to withstand humid, saline coastal sea breezes.
⚡ HESCOM, CESC & GESCOM
HESCOM serves Hubli-Dharwad and Belagavi; CESC serves Mysuru and Hassan; GESCOM covers North Karnataka (Kalaburagi, Ballari) with massive solar insolation levels exceeding 5.2 kWh/m²/day.
