If a 400W solar panel costs ₹12,000:
👉 ₹12,000 ÷ 400 = ₹30 per watt
This helps you compare different solar panels easily.
Latest Solar Panel Price per Watt in India (2026)
Here is a simple breakdown:
Polycrystalline panels → ₹22 – ₹30 per watt
Monocrystalline panels → ₹30 – ₹45 per watt
Bifacial panels → ₹35 – ₹50 per watt
👉 Most homeowners today prefer monocrystalline panels because they give better output.
Total Solar System Cost (Based on Watt)
Understanding price per watt helps estimate full system cost:
1kW solar system → ₹50,000 – ₹80,000
2kW solar system → ₹1 lakh – ₹1.5 lakh
3kW solar system → ₹1.5 lakh – ₹2.5 lakh
