Nimesh Katariya Net metering in India is a billing mechanism allowing rooftop solar customers to export surplus energy to the grid and receive credit against import consumption. Rules vary by state — caps, tariffs, and eligibility set by each State Electricity Regulatory Commission (SERC) and DISCOM.

Application Workflow
- Site survey by certified installer.
- Online application via DISCOM portal (BESCOM, MSEDCL, etc.).
- Technical feasibility approval (2–4 weeks).
- Sanction letter with capacity approval.
- Installation of MNRE-spec equipment (ALMM-listed modules, BIS-certified inverter).
- CEIG inspection for ≥10 kW systems — Heaven Designs prepares the CEIG-compliant electrical drawing package most DISCOMs ask for at this stage.
- Bidirectional meter installation by DISCOM.
- Net metering agreement signing.
- PTO and energization.
Common Mistakes
- Specifying inverter not on DISCOM’s approved list.
- Module not ALMM-listed.
- Wrong sanction load assumption (capacity cap is % of sanctioned, not max load).
- Missing CEIG approval for ≥10 kW.
- Underestimating banking/wheeling charges in commercial solar ROI models.
Best Practices
- Verify state-specific cap, banking, and tariff before quoting.
- Confirm inverter is on the specific DISCOM’s approved list (not just MNRE).
- Apply for net metering before purchasing equipment.
- Use a state-empaneled installer for documentation acceptance.
Key Takeaways
- Net metering in India varies state by state — caps, banking, tariffs differ widely.
- Most states cap individual systems at 100% of sanctioned load, up to 1 MW.
- Tamil Nadu and a few states restrict net metering to small residential; gross metering for larger.
- Required steps: DISCOM application → CEIG approval → installation → meter exchange → PTO.
- Verify with specific DISCOM, not generic state policy, before specifying equipment or pricing the project.
