How net metering works
- Your panels generate electricity during the day.
- Your home uses it first — lights, fans, ACs, fridge.
- Surplus flows to the grid and the net meter records it as export.
- At night, or when solar isn't enough, you draw from the grid — recorded as import.
- Your bill charges energy for import minus export (net units), plus fixed charges.
A month on an Indore net-metered bill
| Reading | Units |
|---|---|
| Imported from grid | 320 |
| Exported to grid | 290 |
| Net billed | 30 |
Energy charges apply to 30 units instead of the ~600 the home actually consumed that month.
Eligibility and capacity
- Consumers with a valid connection from MP West Discom.
- Solar capacity is generally limited in relation to your sanctioned/contract load; a load enhancement can be applied for if needed.
- Equipment must meet technical standards (inverter anti-islanding, protection, earthing).
Process in Indore
| Step | Who | Typical time |
|---|---|---|
| Application (with solar application / portal) | Consumer / vendor | Day 1 |
| Technical feasibility | DISCOM | 1–2 weeks |
| Installation | Vendor | 1–3 days |
| Installation report & request for inspection | Vendor | After install |
| Inspection & net meter fitting | DISCOM | usually 2–4 weeks |
| Commissioning | DISCOM / portal | After meter |
What happens to surplus units?
When exports exceed imports, the surplus is carried forward against future bills and settled as per MPERC's net-metering regulations, usually at a lower rate than you pay to buy power. That's why the best return comes from sizing solar close to your own consumption — see how much solar do I need.
Net metering vs gross metering
| Item | Net metering | Gross metering |
|---|---|---|
| What's measured | Import and export on one meter | All generation sold, all consumption bought |
| Common for | Homes, small businesses | Some large/utility-style projects |
| Value of solar unit | Your full tariff (for self-used units) | Feed-in rate |
Documents
Usually the same as for the subsidy application: electricity bill, ID, property proof, and the installer's technical documents (single-line diagram, equipment details, test reports).
