Net Metering in Ahmedabad: Complete Guide for Torrent Power & UGVCL Customers

Net metering is the arrangement that lets your rooftop solar system's surplus energy flow back into the grid, and be adjusted against the electricity you draw at night or on cloudy days. It is what turns a solar installation into real monthly bill savings rather than just a source of daytime power. If you haven't yet gone through the solar installation process, net metering is typically the last technical step before your system starts saving you money on paper as well as in practice.

How net metering actually works

Once your solar system is installed, your DISCOM - Torrent Power for most of Ahmedabad city, or UGVCL, MGVCL and PGVCL elsewhere in Gujarat - replaces your existing meter with a bi-directional net meter. This meter separately records units imported from the grid (when your solar output is less than your consumption) and units exported to the grid (when your solar output exceeds your consumption, typically in the middle of the day).

At billing time, the DISCOM nets off the imported and exported units. If you exported more than you imported in a cycle, the surplus units are typically carried forward or settled as per the applicable DISCOM policy, rather than paid out in cash in most residential cases. This is why net metering is sometimes called 'unit banking' - unused exported units in one month can offset consumption in a later month.

A worked billing example

Assume a 3.85 kWp system generating roughly 4 units per kWp per day on average in Gujarat, which works out to about 120 units per kWp per month, or approximately 460 units a month for this system size. If a household consumes 350 units in that month and the system exports the rest back to the grid during the day, the net meter would show something like this on the bill:

These figures are illustrative estimates only - actual generation depends on shading, orientation, panel cleanliness and weather, and actual billing depends on your DISCOM's specific net-metering tariff order. Using an approximate residential tariff of ₹7.5 per unit (including fixed charges, stated here as an assumption), a household avoiding roughly 350 units of grid draw a month could see a meaningful cut in its bill.

Application process and documents

Net metering is applied for as part of the overall PM Surya Ghar and DISCOM approval process, usually handled by your installer on your behalf. Broadly, the steps are:

1. Application filed on the national portal along with DISCOM feasibility request, using your latest electricity bill, PAN card and a cancelled cheque.
2. DISCOM technical review of your sanctioned load versus proposed solar capacity.
3. Feasibility approval, followed by installation of the solar system.
4. Site inspection by the DISCOM to verify the installation matches the application.
5. Net meter installation, replacing the existing meter.
6. Commissioning confirmation on the portal, which also triggers subsidy processing.

Typical timeline

From application to a working net meter typically takes four to seven weeks, though this varies with DISCOM workload and how quickly documents are submitted correctly. Subsidy credit of ₹78,000 generally follows four to eight weeks after commissioning. Our PM Surya Ghar subsidy guide for Gujarat covers the subsidy slabs and eligibility in detail.

Common issues and how to avoid them

Meter installation delays

The DISCOM inspection-and-meter-swap step is usually the slowest part of the whole journey because it depends on field staff availability rather than your installer. Keeping your site accessible and responding quickly to inspection scheduling calls helps avoid unnecessary delay.

Feasibility rejection or hold

This usually happens when the proposed system size doesn't match the sanctioned load on record, or when transformer-level capacity in that locality is constrained. Your installer should flag this at the survey stage rather than after application.

Name or address mismatch

If the name on your electricity bill differs from your PAN card or the applicant's name (common in older connections or after property transfer), the application can get stuck. It is worth checking your latest bill's registered name before applying.

Single-phase vs three-phase connections

Most residential systems up to around 5 kWp work fine on a single-phase connection, but larger systems or specific inverter types may require a three-phase supply. This is confirmed during the site survey and factored into inverter selection.

Why net metering matters more than the panels themselves

Two identical solar systems can deliver very different savings purely based on how well net metering is set up and how promptly the DISCOM inspection happens. This is why choosing an installer experienced with your specific DISCOM - reflected in our guide to the best solar company in Ahmedabad - genuinely affects your time-to-savings, not just your installation quality.
