Introduction: Making Solar Affordable for Every Indian Home
India is moving toward a cleaner, more energy-independent futureโand rooftop solar is at the heart of this revolution. However, many homeowners hesitate due to upfront costs.
To solve this, the Government of India launched the Pradhan Mantri Surya Ghar: Muft Bijli Yojana, a flagship scheme that offers significant subsidies on rooftop solar installations for residential homes.
In this guide, we break down everything you need to know about the subsidy, how much you can save, and how to apply.
What Is the Pradhan Mantri Surya Ghar Yojana?
Launched in 2024, this initiative is part of Indiaโs goal to:
Promote clean, decentralized solar power
Enable 1 crore+ households to generate their own electricity
Reduce grid dependency and bring down household power bills
The scheme offers direct subsidies to homeowners, making solar affordable and accessible.
Key Benefits of the Scheme
1. Up to 60% Subsidy on Rooftop Solar Installations
Up to 3 kW: Eligible for 60% subsidy
Above 3 kW up to 10 kW: Additional 20% subsidy
Max capacity eligible for subsidy: 10 kW
A 3 kW system costing โน1.8 lakh would only cost โน72,000 after subsidy.
2. Zero or Low Electricity Bills for 25+ Years
Rooftop solar can offset 70โ100% of your monthly electricity bill.
Net metering ensures unused electricity earns credits
Once installed, electricity is virtually free for 20โ25 years
3. Direct Benefit Transfer (DBT) to Your Account
Subsidy is credited directly to your bank account
Transparent and time-bound process
No middlemenโyou choose the vendor, the government pays the subsidy
4. Free Electricity for Economically Weaker Sections (EWS)
The scheme offers full financial support for families in the EWS and LIG categories, covering:
System installation
Maintenance costs
Application and approvals
Target: 1 crore households to benefit by 2026
Eligibility Criteria
To avail the subsidy:
You must own the house or have long-term occupancy rights
The rooftop must be unshaded and structurally suitable
2. Register your home with basic details and DISCOM info
3. Get site assessed by an empaneled vendor
4. Install the system
5. Apply for net metering
6. Get subsidy credited to your bank account
Expert Advice: Choose Quality Over Cheapest Price
โSubsidy reduces cost, but quality matters. Always use MNRE-registered vendors and Tier-1 panels to ensure longevity and maximum output.โ โ Dr. Karan Shah, Solar Policy Analyst
Introduction: What If Your Electricity Bill Was โน0?
With electricity costs rising steadily across India, more families are turning to solar powerโnot just to generate electricity, but to sell it back to the grid. Thatโs possible through a powerful policy mechanism called net metering.
In this post, weโll explain what net metering is, how it works in India, how much you can save, and what you need to do to benefit from it.
What Is Net Metering?
Net metering is a billing arrangement that allows homeowners who generate electricity from rooftop solar to export excess power to the grid and get credits in return.
Here's how it works:
Solar panels generate electricity during the day.
Your home uses what it needs.
Surplus energy is sent back to the grid.
The net meter calculates both import (from the grid) and export (to the grid).
You pay only for the net units consumed, or get credited for excess energy.
Example: If your system exports 100 units but imports only 90 units in a billing cycle, you are credited for 10 units, reducing or eliminating your bill.
๐ฎ๐ณ Net Metering in India: Key Highlights
Introduced under the Electricity Act, 2003
Mandated by most State Electricity Regulatory Commissions (SERCs)
Applicable for residential, institutional, and commercial users
Maximum system size varies by state (typically 1โ10 kW for homes)
As of 2025:
Most DISCOMs support bidirectional net meters
Some states now offer gross metering as an optionโbut net metering is preferred for household savings
How Net Metering Saves Families Money
Real Savings Example: 5 kW System in Pune
Monthly solar generation: ~600โ700 units
Household consumption: ~500โ600 units
Net savings: โน5,000โโน6,500/month
Annual savings: โน60,000โโน78,000
25-year lifetime savings: โน15โ18 lakhs
Suited For:
Households with โน3,000โโน10,000 monthly electricity bills
Homes with ACs, fridges, geysers, and high appliance usage
โAfter installing a 5 kW system with net metering, our bill dropped from โน6,200 to just โน110,โ says Mrs. Kapoor, Delhi homeowner.

With net metering, youโre not just saving moneyโyouโre contributing to:
Reduced grid load during peak hours
Lower greenhouse gas emissions
Helping India reach its 500 GW renewable target by 2030
For years, many Indian homeowners hesitated to install solar due to the long payback period โ often 7โ8 years or more. But 2024 has changed the game. Thanks to falling solar panel costs, government subsidies, and improved system efficiency, the payback period for residential rooftop solar has dropped to just 3โ5 years in many cases. This means quicker returns and decades of free electricity.
What Is the โPayback Periodโ in Solar?
The payback period means the time it takes to recover the money you spent on your solar system through savings on your electricity bill.
For example:
If your solar system costs โน1,50,000
And it saves you โน30,000 every year on bills
Your payback period = โน1,50,000 รท โน30,000 = 5 years
After that, your electricity is almost free for another 15โ20 years!
The Good News: Solar Payback Is Now Faster Than Ever
In the past, it used to take 7โ8 years to recover your solar investment.
But in 2024, things have changed. Now, most homeowners get their money back in just 3 to 5 years.
Hereโs why:
1. Big Government Subsidies
The Indian government now gives:
Up to 60% subsidy for rooftop solar (for up to 3 kW systems)
Direct money transfer to your bank account
Available under the PM Surya Ghar: Muft Bijli Yojana
A system that costs โน1.8 lakh could cost just โน72,000 after subsidy.
2. Higher Electricity Bills = Faster Savings
Electricity prices are rising. That means:
The more you pay on your current bill, the faster you save
If your monthly bill is โน5,000, you could save โน60,000+ per year with solar
3. Net Metering = Extra Savings
Net metering lets you:
Send extra solar electricity to the grid
Get credits for it
Reduce your monthly bill to โน0 or even earn credits
4. Better Solar Technology
More efficient panels now generate more power in less space
Smart inverters help track usage and improve performance
Panels now last 25โ30 years with minimal maintenance
Real-Life Example
Family: Sharma Family, Jaipur System Size: 4 kW Cost after subsidy: โน1.2 lakh Monthly Bill Before: โน5,500 Monthly Bill After: โน200 Payback Period:~2.5 years Total Lifetime Savings (25 years): โน12โ14 lakhs
โWe were surprised how fast we saved money. It paid for itself in under 3 years,โ โ Mr. Sharma
