One of the first questions every homeowner asks when considering solar is: how much will it actually cost? The honest answer depends on several factors — but in this guide, we'll break it all down clearly so you can plan with confidence.
Average Solar System Costs in Kerala
Under the PM Surya Ghar Muft Bijli Yojana, subsidies are capped at 3 kW (₹78,000 max). Systems larger than 3 kW still qualify for the 3 kW subsidy amount.
What Affects the Price?
Several factors influence the final cost of your solar installation:
- Panel brand & quality — Tier-1 brands like Adani, Waaree, and Vikram cost more but offer 25-year performance warranties.
- Inverter type — String inverters are most common. Microinverters cost more but perform better in shaded conditions.
- Roof type & accessibility — Sloped tile roofs are easier to mount than flat concrete roofs. Difficult access adds labour costs.
- Battery storage — If you want a battery backup system, add ₹50,000–₹1,50,000 depending on capacity.
- Installation complexity — Systems requiring additional civil work or long cable runs cost more.
