Solar Panel Cost Calculator for Indian Homes (2025) – Need Feedback

misbah33

Hello everyone 

I am from India and recently I was exploring solar panel installation costs for residential homes here. The pricing is very dynamic and depends on:

• System size (1kW, 3kW, 5kW, etc.)

• Location & local subsidies

• Type of inverter and battery backup

For example (2025 approx. costs in India):

• 1kW system ≈ ₹65,000 – ₹75,000

• 3kW system ≈ around ₹2,00,000

• 5kW system ≈ ₹3,30,000 – ₹3,80,000

Since these numbers vary a lot, I created a small online calculator tool that helps homeowners:
👉 Solar Panel Cost Calculator in India (2025) – MB Electrical

With this tool, you just enter your average monthly electricity bill, and it gives:

• Recommended solar system size

• Estimated installation cost (updated for 2025)

• Approx. payback period (ROI)  I wanted to share this here to get feedback from experts.

• Does my cost/watt assumption (~₹65 per watt) look realistic for 2025 India?

• How does this compare with current prices in your country?

Looking forward to your suggestions
