Net metering is the mechanism that allows a rooftop solar customer to export surplus electricity to the grid and receive credits on their electricity bill. As a solar installer, you are responsible for completing the net metering application on behalf of your customers — and DISCOM approvals can make or break project timelines. This guide covers exactly what documents you need and how to navigate the process efficiently.
💡 Quick Answer: For DISCOM net metering approval, you need: customer's electricity bill, load sanction letter, single-line diagram (SLD), test report from NABL-accredited lab (for inverter), application form signed by customer + installer, and net meter purchase receipt (in some states). Process takes 15–60 days depending on state.
Why Net Metering Matters for Solar Dealers
Grid-tied solar (the most common type sold to homeowners) only makes economic sense with net metering. Without it, customers can't export excess power and lose significant savings. As an installer, failing to get net metering approved:
- Leaves customer dissatisfied and creates reputational risk
- Delays PM Surya Ghar subsidy disbursement (DISCOM approval is a mandatory step)
- Can delay final payment collection from customer
Master Document Checklist for Net Metering Application
| Document | Who Provides It | Notes |
|---|---|---|
| Net Metering Application Form | DISCOM (download from their website) | Signed by customer |
| Last 3–6 months electricity bill (original/copy) | Customer | Shows Consumer Number & sanctioned load |
| Load Sanction / Connection Letter | Customer / DISCOM | Confirms current sanctioned load |
| Solar System Single-Line Diagram (SLD) | Installer / Engineer | Signed by licensed electrical engineer |
| Inverter Test Certificate (IEC 61727 / IS 16221) | Inverter manufacturer | From NABL-accredited lab |
| Solar Panel Test Certificate (IEC 61215, IEC 61730) | Panel manufacturer | Standard from manufacturer |
| Electrical Contractor Licence copy | Your firm | Valid and current |
| GST Invoice for system supply | Your firm | Shows system cost and tax treatment |
| Site photograph (rooftop with installed panels) | Installer | Date-stamped, geo-tagged in some states |
| ID proof of consumer (Aadhaar/PAN) | Customer | Required in most states |
| Net meter purchase receipt (Type-I bidirectional) | Installer / Customer | Required in Rajasthan, AP, some others |
| NOC from building society (for apartments) | RWA / Housing Society | Only for multi-storey/apartment installs |
State-Wise DISCOM Net Metering Portals (2026)
| State / DISCOM | Portal / Process |
|---|---|
| Maharashtra (MSEDCL) | msedcl.in → Consumer Services → Net Metering |
| Rajasthan (JVVNL, AVVNL, JDVVNL) | energy.rajasthan.gov.in → RSMSSB solar portal |
| Gujarat (DGVCL, MGVCL, PGVCL, UGVCL) | Online via respective DISCOM portal; PM Surya Ghar cases routed via pmsuryaghar.gov.in |
| Karnataka (BESCOM, HESCOM etc.) | bescom.org → Online Services → Solar Rooftop |
| Uttar Pradesh (UPPCL) | upenergy.in → Net Metering Application |
| Delhi (BSES, BRPL, TPDDL) | Respective DISCOM websites; online application |
| Tamil Nadu (TANGEDCO) | tangedco.gov.in → Solar → Net Metering |
| Andhra Pradesh (APEPDCL, APSPDCL) | DISCOM portal; also routed via state nodal agency |
Portal URLs change periodically. Always verify current URLs from the official DISCOM website or your state's nodal energy agency.
Common Reasons for Net Metering Application Rejection
- SLD not signed by a licensed electrical engineer
- Inverter model not on the MNRE-approved inverter list
- System size exceeding sanctioned load limit (typically max 1× sanctioned load)
- Mismatch between system invoice and application form capacity
- Missing IEC certificates for panels or inverter
- Photographs not showing entire installation (roof + panels + inverter)
Tips for Faster Net Metering Approvals
- Use only MNRE-approved panels and inverters — verify at mnre.gov.in approved product list
- Maintain a ready document kit — keep digital copies of IEC certs, SLD templates, and your licence ready for all projects
- Submit physically if portal is slow — some DISCOMs still process physical applications faster
- Follow up on Day 15 — most DISCOMs have a statutory timeline; escalate to the SE (Superintending Engineer) if delayed beyond 30 days
- Build DISCOM relationships — knowing the nodal officer in your area speeds up routine applications

How long does DISCOM net metering approval take?
Under CERC and SERC regulations, DISCOMs are mandated to process net metering applications within 30 days. In practice, Gujarat, Rajasthan, and Maharashtra often process in 15–30 days. UP and Tamil Nadu can take 45–60 days. Delays are common; follow up proactively.
Does the customer pay for the net meter installation?
In most states, the customer bears the cost of the bidirectional net meter (₹2,000–₹5,000 approximately). Some DISCOMs supply and install the meter themselves and charge it to the customer's account. Clarify this upfront so customers are not surprised.
Can I submit net metering applications for multiple DISCOMs?
Yes, as long as you are a registered vendor/contractor with each DISCOM. Each DISCOM has its own process and application form. Maintain separate document sets for each.
