How Much Does a 3kW Solar System Cost in Rajasthan? (2025 Guide)
If you're a homeowner in Sikar or anywhere in Rajasthan with a monthly electricity bill between ₹2,000–₹4,000, a 3kW rooftop solar system is usually the sweet spot. Here's exactly what it costs, what subsidy you'll get, and how fast it pays for itself.
3kW System Cost Breakdown
| Component | Approx. Cost (₹) |
|---|---|
| Solar panels (3kW) | ₹90,000 – ₹1,05,000 |
| Inverter | ₹18,000 – ₹25,000 |
| Mounting structure & wiring | ₹12,000 – ₹18,000 |
| Installation labor | ₹8,000 – ₹12,000 |
| Total (before subsidy) | ₹1,28,000 – ₹1,60,000 |
Government Subsidy Under PM Surya Ghar Yojana
For a 3kW system, eligible homeowners can receive a central government subsidy of approximately ₹78,000 (as per current PM Surya Ghar Muft Bijli Yojana slabs, subject to change — always confirm current rates before booking).
📌 Net cost after subsidy: Roughly ₹50,000 – ₹82,000 depending on your equipment choice and installer quote.
How Fast Does It Pay for Itself?
A well-installed 3kW system in Rajasthan (which gets excellent sun exposure most of the year) typically generates enough electricity to cover a ₹2,500–₹3,500 monthly bill almost entirely. Most homeowners recover their investment in 3.5 to 5 years, and the system continues producing free electricity for 20-25 years after that.
What Affects Your Final Price?
Three things move the number most: the brand of panels you choose (Indian vs. imported), whether you go with a string inverter or microinverters, and your roof's condition (older roofs sometimes need reinforcement, adding cost).
