Net metering is what makes grid-tied solar pay. Learn how it works, step by step.

Net metering is the quiet mechanism that turns a rooftop plant into a bill-cutting machine. Without it, surplus solar energy is wasted; with it, every unit you export offsets a unit you import later. This page on solar net metering in Raipur explains how the system works, how CSPDCL processes it, how bills are calculated and what to do when something goes wrong.
Quick answer: you apply for feasibility, install the system, get a bidirectional meter and pass inspection. After that, your bill is based on net units.
| Step | What happens | Typical time |
|---|---|---|
| Feasibility application | Vendor applies on your behalf; CSPDCL checks load and network | Several days to a few weeks |
| Installation | Plant is installed and tested | 3 - 5 days |
| Net meter request | Bidirectional meter fitted | 1 - 4 weeks |
| Inspection | Officer inspects the plant | Scheduled with CSPDCL |
| Commissioning | System goes live and billing switches to net | After inspection |
Net-metered capacity is generally linked to your sanctioned load. If you want 5 kW on a 3 kW load, apply for enhancement early. Check the figure on your bill; see how to read your CSPDCL bill before going solar.
| Month | Imported | Exported | Net units |
|---|---|---|---|
| March | 170 | 230 | -60 (credit) |
| April | 260 | 230 | 30 |
| May | 340 | 220 | 120 |
Illustrative numbers. See the full walkthrough in net metering bill example.
Net-metering rules typically allow credits to carry forward, with year-end settlement rules set by the regulator. The details can change, so ask CSPDCL for the current terms in writing.
| Problem | Likely cause | Fix |
|---|---|---|
| Exports not recorded | Meter not configured or wiring fault | Ask CSPDCL to check; share inverter logs |
| Old readings used | Data entry delay | Provide dated meter photos |
| Credit missing | Carry-forward not applied | Raise with the division office with past bills |
| Delay in meter | Stock or scheduling | Vendor follows up weekly |
The process is similar, but capacity limits, tariff categories and metering arrangements differ. Societies with several meters may ask about group or virtual net metering, which national rules describe but local implementation must be confirmed. See solar for apartments and societies and CSPDCL net metering guide.
A home with a 3 kW system generates 4,300 units a year. It uses 1,900 directly and exports 2,400. It imports 2,100 at night and in heavy months. Net units are 2,100 minus 2,400, close to zero over the year. The owner pays mostly fixed charges, and the bill falls by 70 to 90 per cent compared with life without solar.
National rules describe group and virtual net metering, where generation from one site can be credited across several meters, which helps housing societies and consumers without suitable roofs. Whether and how CSPDCL implements these in Chhattisgarh, and under what conditions, should be confirmed before designing around them. Ask for the current regulation or order in writing.
| Record | Why |
|---|---|
| Dated photo of meter before and after commissioning | Baseline for disputes |
| Monthly import and export readings | Check bills |
| Inverter generation logs | Cross-check exports |
| Copies of feasibility and inspection approvals | Proof of status |

A billing arrangement where a bidirectional meter records units you import from the grid and units you export. You pay for net units, plus fixed charges and duties.
The distribution company, CSPDCL, after feasibility approval and installation of the plant.
Net-metered capacity is linked to your sanctioned load, so a larger system may need a load enhancement.
They are usually carried forward to offset later billing cycles, with settlement per current regulatory rules. Confirm the latest terms.
Fixed charges, duties and months with net imports remain.
