The Payback Analysis
Let's run the numbers for a standard 3kW On-Grid system in an Indian Tier-1 city.
- System Cost: ₹1,80,000 (Average)
- Govt Subsidy: -₹78,000
- Your Final Investment: ₹1,02,000
- Generation: ~360 Units / Month
- Monthly Savings: ₹3,240 (@ ₹9/unit average)
- Annual Savings: ₹38,880
- Break-Even Period: 2.6 Years!
After 2.6 years, your electricity is practically free for the next 22 years. This is a 38% annual return on your capital, which beats every Mutual Fund or FD in the market.
Net Metering: The Secret Sauce
In an "On-Grid" system, you don't need batteries (which are expensive and last only 5 years). Instead, the solar energy you generate during the day is sent to the grid. At night, you take energy back. At the end of the month, you only pay for the 'Net' consumption. If you generate more than you use, the units often carry forward to the next month.
Crucial Pre-Installation Tip
"Check your Sanctioned Load." Most local electricity boards (DISCOMs) won't allow you to install a solar system capacity higher than your home's sanctioned load. If your load is 2kW and you want a 3kW solar system, you must first apply for a 'load enhancement' to avoid technical rejection of your subsidy.
How to Apply? (Avoid Scams)
Only use the Official Portal: pmsuryaghar.gov.in. Do not pay any "registration fee" to private agents. Choose a vendor from the 'Empanelled List' who has experience with net-metering in your specific city.
