Your Solar Panels Are Up. So Why Is Your Bill Still the Same?
The panels are on your roof. The inverter is mounted. The installer has finished. But weeks later, there is still no net meter, no subsidy in your bank account, and no change in your electricity bill.
If this sounds familiar, you are not alone. A solar net metering application delay is the most common complaint we hear from homeowners and factory owners across West Bengal. Installing a rooftop system takes 2 to 5 days. Getting it legally connected to the WBSEDCL grid can take far longer.
The good news: most delays are predictable, and most are avoidable. They come from a small set of causes that repeat across Siliguri, Kolkata, Jalpaiguri and the rest of the state.

Why Net Metering Timing Matters More Than Ever in 2026
Net metering is not a formality. It is the step that turns your rooftop plant into savings. Here is why getting it right matters now.
1. New WBERC rules changed the process. The WBERC Grid Interactive Rooftop Solar Photovoltaic System for Prosumers Regulations, 2025 came into effect on 31 July 2025. They give you three options: net metering, net billing and gross metering. Choosing the wrong one, or applying under old assumptions, causes confusion and rework.
2. Your subsidy depends on it. Under PM Surya Ghar Muft Bijli Yojana, the central subsidy of up to ₹78,000 for homes is released only after the system is inspected and commissioned with a net meter. No net meter means no subsidy.
3. Tariffs keep rising. WBSEDCL domestic consumers in higher slabs already pay roughly ₹7 to ₹8 per unit before fixed charges and duty. Every month without net metering is a month of full-price bills.
4. Discoms have targets to meet. The 2025 regulations set rooftop solar targets for WBSEDCL of 100 MW in 2025-26, rising to 195 MW in 2026-27 (source). More applications mean busier sub-divisions. Clean files move faster.
5. Grid capacity is first come, first served. Total solar on a single distribution transformer is capped. In fast-growing localities, early applicants get the capacity. Late or incomplete applications may be told the transformer is full.
6. Commercial plants lose the most. A 50 kW factory system waiting three months can lose about ₹1.4 lakh in savings. For C&I owners, delay is a direct hit on payback.
For background on how the three settlement options compare, see [Internal link: Net Metering vs Net Billing vs Gross Metering in West Bengal].
How the WBSEDCL Net Metering Process Works
Let’s start with the basics. Net metering means the solar power you send to the grid is offset against the power you draw from it. A bidirectional (net) meter records both directions. Under the 2025 WBERC rules, any surplus left at the end of the year is reset, so the system should be sized to your own use.
Who is eligible
- Any WBSEDCL consumer with a sanctioned load of at least 1 kW
- Resident Welfare Associations and housing societies
- System size up to 500 kW or your sanctioned load, whichever is lower
That last point is where many delays begin. We explain why in the next section.
The process, step by step
- Application. Apply online on the WBSEDCL portal (or the PM Surya Ghar portal for subsidy cases) with Form S1, your consumer ID and the planned capacity. The 2025 regulations set the fee at ₹1,000 for low and medium voltage consumers and ₹5,000 for HV/EHV.
- Feasibility. Systems up to 10 kW are approved automatically without a feasibility study. Above 10 kW, WBSEDCL must complete a technical study within 15 days.
- Quotation and agreement. WBSEDCL issues a quotation (if any work or meter cost applies). You pay it and sign the connection agreement (Form S2).
- Installation. Your EPC installs the plant. The 2025 rules allow 180 days, with a 90-day extension.
- Electrical safety clearance. A clearance from the Chief Electrical Inspector (CEI), or self-certification where allowed, is submitted.
- Work completion report. Form S3 is filed with module, inverter and cable test reports, structure data sheets and a single-line diagram.
- Connectivity inspection and testing. WBSEDCL engineers inspect the installation and test it.
- Net meter installation and synchronisation. The bidirectional meter is fitted, the plant is synchronised, and billing switches to net metering.
- Subsidy release (PM Surya Ghar cases). The commissioning report goes up on the national portal, and the subsidy is credited to your bank account.
Official timelines WBSEDCL is expected to follow
The table below uses WBSEDCL’s own connection procedure, Procedures-C (2021), updated with the 2025 WBERC changes where they apply.
| Stage | Expected time limit | Who acts |
|---|---|---|
| Feasibility, up to 10 kW | Automatic approval (2025 rules) | WBSEDCL |
| Feasibility, above 10 kW | Within 15 days (2025 rules) | WBSEDCL |
| Non-feasibility intimation | Within 7 days of inspection | WBSEDCL |
| Pay quotation and sign Form S2 | Within 90 days of quotation | You |
| Install plant and get safety clearance | Within 180 days, +90 days extension | You and your EPC |
| Connectivity inspection and testing | Within 10 days of work completion report | WBSEDCL |
| Net meter installation and synchronisation | Within 15 days of successful inspection and fitness certificate | WBSEDCL |
Timelines are indicative and drawn from published WBSEDCL and WBERC documents. Actual timelines can vary by sub-division, season and workload. Always check the latest notice on the WBSEDCL portal.
Add it up: on a clean residential file, the WBSEDCL side of the process should take roughly 4 to 6 weeks after installation. When it takes 3 to 4 months, one of the causes below is usually responsible.

10 Reasons Your Net Metering Application Gets Delayed
Most stuck files we review fall into one of these ten causes. The first six can be fixed before you even apply.
| # | Cause | Stage it hits | Who can prevent it |
|---|---|---|---|
| 1 | Solar capacity above sanctioned load | Application | You and your EPC |
| 2 | Name or address mismatch on the bill | Application | You |
| 3 | Incomplete or wrong documents | Application and completion | Your EPC |
| 4 | Distribution transformer already full | Feasibility | Partly (apply early) |
| 5 | Old meter or service line needs upgrading | Feasibility | You and your EPC |
| 6 | Quotation or deadlines missed | Agreement | You |
| 7 | Non-compliant panels or inverter | Inspection | Your EPC |
| 8 | Installation fails inspection or safety clearance | Inspection | Your EPC |
| 9 | Net meter stock or metering crew shortage | Meter installation | WBSEDCL (follow-up helps) |
| 10 | PM Surya Ghar portal mismatches | Subsidy | Your EPC and you |
1. Your solar capacity is higher than your sanctioned load
The 2025 regulations cap your system at your sanctioned load. A home with a 2 kW sanctioned load cannot get net metering for a 4 kW plant. You first need a load enhancement: a separate application, a fee, and sometimes a new meter or service cable. Do this before you apply for solar, not after.
2. The name on the electricity bill does not match
The connection is often still in a late parent’s name, a previous owner’s name, or a landlord’s name. WBSEDCL will not sign a net metering agreement with someone who is not the registered consumer. A name change (mutation) must be completed first, and that needs ownership or succession documents.
3. Incomplete or incorrect documents
Missing signatures, an unsigned Form S2, a blurred ID, or a work completion report without test reports can send a file back. Each return restarts the clock. Common gaps include:
- Module, inverter and cable test certificates
- Mounting structure data sheet
- Single-line wiring diagram
- CEI clearance or self-certification acknowledgement
4. The local transformer is already full
WBSEDCL limits the total solar capacity on each distribution transformer and approves applications on a first come, first served basis. In busy localities, your file may be told the transformer has no room. Options then include waiting for an upgrade, reducing capacity, or exploring a different settlement model.
5. Your meter or service line needs an upgrade
During inspection, engineers may note that the service line, meter board or phase needs alteration. A single-phase home planning a larger three-phase system is a classic example. Under WBSEDCL procedure, the consumer bears the cost of such alterations, and the work adds a new step.
6. A payment or deadline was missed
Under Procedures-C, the quotation must be paid and Form S2 submitted within 90 days. Miss this, and the application can be cancelled with the fee forfeited. Missing the work completion deadline can also lead to cancellation after notice. Starting again costs weeks.
7. Your panels or inverter are not compliant
Grid-tied inverters must have anti-islanding protection, and the 2025 rules make harmonic filters and safety certification mandatory. Subsidy cases also require equipment that meets central rules, including ALMM-listed modules. Cheap, uncertified equipment is one of the most expensive mistakes you can make.
8. The installation fails inspection
If the plant is not suitable for synchronisation, WBSEDCL issues a connectivity failure letter. Typical reasons are poor earthing, a missing AC isolator, wrong cable sizing, unsafe DC wiring, or missing labels. Each failure means rework and a fresh inspection date.
9. Net meters or metering crews are not available
Even after a successful inspection, the meter must be procured, tested and fitted. During demand peaks, sub-divisions can run short of bidirectional meters or field staff. A polite, documented follow-up with the sub-division office usually moves things along.
10. The PM Surya Ghar portal does not match WBSEDCL records
For subsidy cases, the consumer details, vendor details and bank account on pmsuryaghar.gov.in must match. An unregistered vendor, a wrong IFSC code, or a status not updated by the discom can hold the subsidy for months after the net meter is fitted.

What a Net Metering Delay Really Costs You
A delay is not just an inconvenience. In most cases, the plant should not be connected to the grid until the net meter is fitted. So the savings from those months are lost, not postponed.
We’ll use two simple assumptions for West Bengal:
- Generation: about 4 units per kW per day, or roughly 120 units per kW per month (annual average; lower in monsoon, higher in spring)
- Tariff saved: about ₹7.50 per unit for homes in higher slabs and ₹8 per unit for commercial and industrial consumers
Example 1: 3 kW home in Siliguri
A family with a 3 kW sanctioned load installs a 3 kW system under PM Surya Ghar.
- Monthly generation: 3 × 120 = 360 units
- Monthly savings: 360 × ₹7.50 = ₹2,700
- Delay of 3 months: ₹8,100 lost
- Plus ₹78,000 subsidy waiting in the queue
Example 2: 5 kW home near Kolkata (WBSEDCL area)
The owner applied for 5 kW but had only a 3 kW sanctioned load. Load enhancement added 4 months.
- Monthly generation: 5 × 120 = 600 units
- Monthly savings: 600 × ₹7.50 = ₹4,500
- Delay of 4 months: ₹18,000 lost
- Subsidy of ₹78,000 (the cap for 3 kW and above) also held for 4 months
Example 3: 50 kW warehouse in Jalpaiguri
The file was returned twice for missing inverter test reports.
- Monthly generation: 50 × 120 = 6,000 units
- Monthly savings: 6,000 × ₹8 = ₹48,000
- Delay of 3 months: ₹1,44,000 lost
Example 4: 200 kW tea estate or rice mill
The local transformer needed a capacity check, adding 2 months.
- Monthly generation: 200 × 120 = 24,000 units
- Monthly savings: 24,000 × ₹8 = ₹1,92,000
- Delay of 2 months: ₹3,84,000 lost
Cost of delay at a glance
| System size | Monthly units | Savings lost per month | 1-month delay | 3-month delay | 6-month delay |
|---|---|---|---|---|---|
| 3 kW home | 360 | ₹2,700 | ₹2,700 | ₹8,100 | ₹16,200 |
| 5 kW home | 600 | ₹4,500 | ₹4,500 | ₹13,500 | ₹27,000 |
| 10 kW home or shop | 1,200 | ₹9,000 | ₹9,000 | ₹27,000 | ₹54,000 |
| 50 kW commercial | 6,000 | ₹48,000 | ₹48,000 | ₹1,44,000 | ₹2,88,000 |
| 200 kW industrial | 24,000 | ₹1,92,000 | ₹1,92,000 | ₹5,76,000 | ₹11,52,000 |
Disclaimer: Figures are illustrative estimates. Actual generation depends on location, shading, roof angle and weather. Actual savings depend on your tariff category, slab, fixed charges, duty and the settlement model you choose. Homes use ₹7.50/unit and the 10 kW row uses the residential rate; commercial rows use ₹8/unit.

How to Avoid Net Metering Delays: A Practical Checklist
The simplest way to avoid a delay is to fix problems before WBSEDCL finds them. Here is the checklist we use on every SolarLogix project.
Before you sign with an installer
- Check your sanctioned load on your latest bill. Is it equal to or higher than the solar capacity you want?
- Confirm the connection is in your own name. If not, start the name change now.
- Clear any pending electricity dues.
- Ask your EPC which settlement model (net metering, net billing or gross metering) suits your usage.
- Confirm the panels are ALMM-listed and the inverter is certified for grid connection.
Documents to keep ready
| Document | Needed for | Common mistake |
|---|---|---|
| Latest electricity bill | Consumer ID, name, sanctioned load | Bill in someone else’s name |
| Photo ID and address proof | Application | Blurred or expired copy |
| Ownership proof or NOC | Rooftop rights | Missing NOC from co-owners or society |
| Bank details (cancelled cheque) | Subsidy credit | IFSC or name mismatch |
| Signed Form S2 agreement | Connection agreement | Unsigned pages or wrong date |
| Form S3 with test reports and SLD | Work completion | Missing inverter or cable certificates |
| CEI clearance or self-certification | Safety approval | Acknowledgement copy not attached |
After installation
- File the work completion report the same week the plant is finished.
- Keep a copy of every receipt, acknowledgement and application number.
- Track status online every week.
- Be present (or have your EPC present) on the inspection date.
If your file is stuck
- Check the status online and note the exact stage and date.
- Visit or write to your WBSEDCL sub-division / Customer Care Centre with your application number. Keep it polite and in writing.
- Escalate to the division or regional office if the published timeline has clearly passed.
- Use WBSEDCL’s grievance redressal mechanism, and beyond that, the Electricity Ombudsman under WBERC.
A good EPC handles all of this for you. That is part of what you pay for.
Financing: why delay matters even more on an EMI
Many homeowners now buy solar on a bank loan, and several public sector banks offer rooftop solar loans linked to PM Surya Ghar. The catch: your EMI starts on schedule, even if your net meter does not. A 3-month delay means three EMIs paid with no savings to offset them. Commercial buyers using term loans or accelerated depreciation face the same mismatch. Compare your options in [Internal link: Solar Financing & EMI Options in West Bengal 2026].
Warranty: does a delay affect it?
Module and inverter warranties usually start from the invoice or installation date, not the net metering date. Solar panels typically carry a 25-year performance warranty, and inverters 5 to 10 years, depending on the brand. A long wait before commissioning quietly uses up part of that cover. Always check the warranty start date in your documents.
Frequently Asked Questions
1. How long does net metering take in West Bengal? On a clean file, the WBSEDCL side should take about 4 to 6 weeks after installation. Files with load, name or document issues often take 3 months or more.
2. Why is my net meter not installed even after inspection? Usually because of meter stock, crew availability, or a pending fitness certificate. Ask your sub-division for the exact reason in writing.
3. Can I use my solar system before the net meter is installed? In most cases, no. The plant should not be connected to the grid until WBSEDCL synchronises it with the net meter.
4. Does a delay affect my PM Surya Ghar subsidy? Yes. The subsidy is released only after commissioning with a net meter. A net metering delay delays the subsidy.
5. How much subsidy can I get for a home system? Up to ₹78,000 under PM Surya Ghar for residential systems of 3 kW and above. Check pmsuryaghar.gov.in for the current amount.
6. Can I install more solar than my sanctioned load? No. Under the 2025 WBERC rules, capacity is capped at your sanctioned load or 500 kW, whichever is lower. Increase your load first.
7. How long does a load enhancement take? It varies by sub-division and whether a new meter or cable is needed. Start it before you apply for solar.
8. Do systems up to 10 kW need a feasibility study? No. The 2025 rules provide automatic approval up to 10 kW. Above 10 kW, a technical study must be done within 15 days.
9. What is the application fee? ₹1,000 for low and medium voltage consumers and ₹5,000 for HV/EHV consumers under the 2025 regulations.
10. Who pays for the net meter? The 2025 rules say discoms bear infrastructure costs for systems up to 10 kW. For larger systems, metering costs may apply. Check your quotation.
11. My connection is in my late father’s name. What should I do? Apply for a name change with WBSEDCL using succession documents before applying for net metering.
12. What if the transformer in my area is full? You may need to wait for an upgrade or reduce capacity. Applications are approved first come, first served, so apply early.
13. Is net metering available for factories and commercial buildings? Yes. Commercial and industrial consumers can choose net metering, net billing or gross metering under the 2025 rules, within the 500 kW cap.
14. What is the difference between net metering and net billing? Net metering offsets exported units against imported units. Net billing pays a feed-in tariff for exported units and bills imports at the normal tariff.
15. What happens to extra units at year end? Under net metering in the 2025 rules, any annual surplus is reset. Size your system to your own consumption.
16. Why did my inspection fail? Common reasons are poor earthing, missing AC isolator, wrong cable sizing, or non-certified inverters. Your EPC must fix them and request a re-inspection.
17. Do I need a CEI clearance? WBSEDCL procedure requires a CEI clearance or, where eligible, self-certification acknowledged by the Electrical Inspector. Your EPC should arrange it.
18. Can my installer apply on my behalf? Yes. A registered EPC can file and track the application. You still need to sign key forms.
19. Does CESC follow the same process? No. CESC (Kolkata) has its own process. This guide covers WBSEDCL consumers.
20. Will a delay void my panel warranty? No, but the warranty clock usually starts at invoice or installation, so a long delay uses up part of it.
21. How do I escalate a stuck application? Go to your sub-division in writing, then the division or regional office, then WBSEDCL’s grievance forum, and finally the Electricity Ombudsman.

Net Metering Across West Bengal: Local Notes
Siliguri: Rapid rooftop growth in residential wards means transformer capacity can fill up in some localities. Apply early.
Kolkata: Check your distributor first. WBSEDCL areas follow this process; CESC areas in the city have their own.
Jalpaiguri and Cooch Behar: Many older connections are still single-phase or in a family member’s name. Sort these out before applying.
Darjeeling and hill areas: Shading, structure design and access affect inspection scheduling. Plan installation outside the heavy monsoon months.
Malda and Raiganj: Commercial users such as cold stores and rice mills should check sanctioned load and contract demand carefully before sizing.
