Introduction
As electricity bills climb and environmental awareness grows, more Indian households are opting for solar energy. But what does this solar panel cost and how does the installation process work? In 2025, rooftop solar installations range between ₹25–50 per watt for the panels, with total system costs, installation steps, government subsidies, and net metering requirements all guiding your decision. Here’s everything you need to know.
1. 📊 Solar Panel Cost per Watt
Panel prices in India in 2025 are shaped by technology and efficiency:
- Monocrystalline panels: ₹28–63 per watt
- Polycrystalline panels: ₹20–32 per watt
- Bifacial panels: ₹24–52 per watt
These rates reflect solarclue and Fenice Energy data .
2. 🏠 Total System Costs by Capacity
Total system cost includes panels, inverter, mounting, wiring, labor, and logistics.
| System Size | Cost Before Subsidy | After Subsidy |
|---|---|---|
| 1 kW | ₹60k–85k | ₹40k–50k |
| 2 kW | ₹1.2L–1.7L | ₹80k–1L |
| 3 kW | ₹1.5L–2.15L | ₹1.2L–1.5L |
| 5 kW | ₹2.3L–3.57L | Approx ₹2L–2.5L |
| 10 kW | ₹4L–6L | ₹4L–5L |
These align with Roof Solarly, Anmak Solar, and Delta data.
3. 💰 Government Subsidies
Under the PM Surya Ghar Muft Bijli Yojana:
- 1–3 kW systems: 20–40% subsidy (~₹20k–₹60k per kW)
- 3–10 kW systems: ~₹15k/kW
- Above 10 kW: no subsidy
These reduce your net payment significantly.
4. 📐 Installation Process Steps
- Site survey: Assess roof direction, shading, load capacity, and energy needs.
- System design: Customize panel capacity, inverter type, and mounting setup.
- Mounting: Install rooftop frames at 15–20° tilt.
- Panel installation: Secure modules on rails using bolts and clamps.
- Wiring & inverter connection: Link panels to inverter, and if off-grid, to batteries.
- Grid connection: For on-grid systems, connect to meter board & install bidirectional “net-meter” .
- Testing & commissioning: Turn system on and verify performance via inverter display.
- Earthing: Implement safety earthing to grounding rods .
- Net-metering registration: Submit application to DISCOM and sign agreement .
5. 🧾 Net-Metering & Savings
Net-metering allows you to export excess power to the grid, earning credits. Karnataka, Andhra Pradesh, and most states support this.
6. ⏳ Payback and ROI
Typical payback is 3–6 years depending on system size and usage. After the payback period, utilities drop to near zero and your ROI increases solar panel cost.
7. 📋 Challenges & Considerations
- Initial cost remains high despite subsidies .
- Installation complexity and permission delays—some users report bureaucratic hurdles and paperwork .
- Space and shading: rooftops need clear access and sufficient space.
- Battery backup adds significantly to cost—typically ₹20k–1L+ depending on capacity .
8. 🗣️ Real-World Feedback
“2.1 L for 3 kW setup (excluding subsidies)… Net cost ₹165 k after central/state subsidies.”—Lucknow user on Reddit .
This reflects real-life prices and subsidy mechanisms.
Conclusion
In 2025, solar panel prices in India range from ₹25–50/watt and total system costs from ₹60k (1 kW) up to ₹6L (10 kW) before subsidies. Government incentives, net metering, and long-term savings make solar a compelling choice. The installation path—from survey to commissioning—is streamlined, but understanding each step ensures a smooth experience. By factoring in capacity, site conditions, and financial help, solar becomes an eco-friendly and cost-effective investment.
