What Is Karnataka Solar Subsidy 2026? (Simple Explanation)

Karnataka does not provide a separate state-only subsidy. Instead, Karnataka homeowners get the benefit under the Central Government Rooftop Solar Subsidy Programme, currently implemented through MNRE (Ministry of New & Renewable Energy) and routed through respective electricity supply companies (DISCOMs) such as:

BESCOM – Bengaluru
MESCOM – Mangaluru region
HESCOM – Hubballi-Dharwad region
GESCOM – Kalaburagi region
CESC – Mysuru region

So when people say “Karnataka Solar Subsidy”, they are referring to the Central Rooftop Solar Subsidy applicable to Karnataka residents.

Karnataka Solar Subsidy Amount 2026 (Expected Range)

2 kW	Medium homes	Fans + lights + appliances	Government financial support applicable
3 kW	Most common	Full home base load	Government financial support applicable

Types of Rooftop Solar Systems in Karnataka

Before applying, you should understand the type of system.

1️⃣ On-Grid Solar System (Best for Subsidy)

✔ Connected to the electricity grid
✔ Net-metering enabled
✔ Excess power exported to grid
✔ Bills drastically reduce
✔ Eligible for subsidy

This is the most recommended category.

2️⃣ Hybrid Solar System

✔ Grid + Batteries
✔ Works even during power cuts
✔ More expensive
✔ Limited subsidy support traditionally

3️⃣ Off-Grid System (Battery Only)

✔ Stand-alone
✔ Not connected to grid
✔ Works even when BESCOM power fails
❌ NOT eligible for subsidy

How Much Does Rooftop Solar Cost in Karnataka (2026 Estimate)?

Cost depends on:

System size (kW)
Brand of panels
Inverter type
Installation quality
Roof type
Vendor pricing

Indicative Cost Trend (Before Subsidy)

Capacity	Estimated Cost Range (₹)
1 kW	₹55,000 – ₹75,000
2 kW	₹1,00,000 – ₹1,40,000
3 kW	₹1,60,000 – ₹2,20,000
5 kW	₹2,50,000 – ₹3,50,000
8–10 kW	₹4,00,000 – ₹7,00,000

After Subsidy

The effective cost reduces significantly depending on the approved slab and policy at time of approval.

A properly installed system usually pays for itself in 3–5 years through savings and thereafter generates almost free electricity for the remaining lifespan (typically 20–25 years).

Karnataka Solar Subsidy Application Process (Step-By-Step Guide)

Once approved → installation can begin.

Step 5: Solar Installation
