How to Switch Your Home to Rooftop Solar in 2026 India: Cost Breakdown, Savings, and Setup Guide

With rising electricity prices and improved government incentives, rooftop solar has become an attractive option for homeowners in India. Under the PM Surya Ghar Muft Bijli Yojana, eligible residential consumers can receive a central subsidy of up to ₹78,000, making solar installations more affordable. 

Step 1: Check Your Electricity Usage

Before choosing a solar system, review your monthly electricity bill.

• Up to 150 units/month: 1–2 kW system
  
• 150–300 units/month: 2–3 kW system
  
• Above 300 units/month: 3–5 kW or larger system
  

Selecting the right size helps maximize savings.

Step 2: Understand the Cost

Typical installation costs before subsidy are:

• 1 kW: ₹55,000–₹90,000
  
• 2 kW: ₹1.1 lakh–₹1.6 lakh
  
• 3 kW: ₹1.6 lakh–₹2.2 lakh
  

Eligible homeowners can receive government subsidies, reducing the overall upfront cost. 

Step 3: Install Through an Approved Vendor

Choose an empanelled vendor approved by your local DISCOM. A typical rooftop solar system includes:

• Solar panels
  
• Inverter
  
• Mounting structure
  
• Wiring and safety equipment
  
• Net meter
  

Step 4: Apply for Net Metering

Net metering allows excess electricity generated during the day to be exported to the grid, helping reduce future electricity bills.

How Much Can You Save?

A properly sized rooftop solar system can reduce electricity bills by 50% to 90%, depending on your energy consumption and system size. Most residential systems recover their installation cost within 3 to 6 years, while solar panels typically last 25 years or more. 

Conclusion

Rooftop solar is becoming one of the smartest long-term investments for Indian homeowners. With lower installation costs, government subsidies, and substantial savings on electricity bills, switching to solar in 2026 is more affordable than ever. Choosing the correct system size and an approved installer can help you maximize both savings and performance.
