How to Pay Rs 0 for Electricity and Actually Earn Money with Solar

It sounds too good to be true: a monthly electricity bill of zero, and on top of that, the utility paying you. But with the right rooftop solar setup and net metering, this is genuinely achievable for Indian households in 2026. The secret is not magic — it is sizing your system correctly and understanding how the grid credits your surplus power. Here is exactly how it works.

The mechanism: net metering

When you install a grid-connected solar system, your meter runs in two directions. During the day, your panels often produce more electricity than your home uses. That surplus flows back into the grid, and your DISCOM credits you for it. At night, or when your panels aren't producing enough, you draw from the grid and use up those credits.

At the end of the billing cycle, you only pay for the net electricity you consumed — hence the name. If your panels generated as much as you used, your bill nets to zero.

How a Rs 0 bill becomes earnings

Here is a simple illustration. Suppose your household would normally consume around Rs 2,000 worth of electricity in a month, but your solar system generates the equivalent of Rs 2,500 worth and exports the difference.

• Your consumption is fully covered by your own generation, so your bill is Rs 0.
• The extra Rs 500 worth of exported power becomes a credit you can carry forward or, depending on your DISCOM's policy, settle in your favour.

Over a year, a slightly oversized system can build up enough credits to cover the months when generation dips, keeping your effective bill at or near zero.

Two ways your roof makes money

1. Net-metering credits — the day-to-day mechanism above, where exported power offsets or eliminates your bill.
2. Avoided cost over decades — every unit you generate is a unit you don't buy at ever-rising tariffs. Across the 25-plus-year life of the panels, that adds up to lakhs of rupees you simply never spend.

Together, these turn a passive rooftop into an income-generating asset.

The role of the subsidy

Government support makes the maths even better. Under the PM Surya Ghar Muft Bijli Yojana, eligible homeowners receive Central Financial Assistance that lowers the upfront cost, helping many households reach breakeven in roughly three years. After that, the system effectively prints savings. You can read more about claiming this in our guides on the solar blog.

How to set yourself up for a Rs 0 bill

• Right-size the system. Match generation to your annual consumption — not just your average month. Slightly oversizing can absorb seasonal dips.
• Insist on net metering. It is both required for the subsidy and essential to earning credits.
• Use quality equipment. Reliable panels and inverters protect your generation — and your savings.
• Maintain the system. Periodic cleaning keeps output high, which keeps your bill low.

A few honest caveats

Net-metering rules, export rates and credit-settlement policies vary by state and DISCOM, and they can change. A genuine Rs 0 bill depends on correct sizing and your local policy. The goal is realistic and common — but it should be designed for, not assumed.

How Solnce helps

Hitting a zero bill is a design problem, and design is what we do best. Solnce analyses your past consumption, sizes a system that targets net-zero (or better), sets up net metering with your DISCOM, and helps you claim the subsidy that speeds up your payback. We operate across Gujarat, Delhi, Punjab, Tamil Nadu, Maharashtra, Karnataka and more, and we'll come back to you with a detailed assessment quickly. If you'd like to spread the cost, we can also arrange solar loans.
