Documents Required for Solar Net Metering in Delhi

Applying for rooftop solar net metering in Delhi? Your electricity distributor will usually need more than a simple solar-panel quotation. The application can involve consumer and property documents, roof-rights proof, technical drawings, equipment specifications, connection forms, declarations and post-installation records.

This guide explains the documents commonly required for BSES, TPDDL and NDMC-related solar net-metering applications, why each document matters, what tenants and apartment owners should arrange, and which post-installation papers you should keep for inspection and subsidy processing.

Quick Answer

For a residential solar net-metering application in Delhi, keep your latest paid electricity bill, consumer or CA number, identity proof, ownership or occupancy proof with roof rights, owner or tenant NOC where applicable, solar-system technical details, a single-line diagram, net-metering application and connection-agreement forms, and any required declarations.

After installation, you may also need photographs, panel and inverter serial numbers, warranty certificates, testing reports, a completion or installation certificate, inspection records and commissioning documents.

The exact checklist depends on your electricity distributor. BSES, TPDDL and NDMC may use different forms, portal routes and document requirements. Do not rely on a generic internet checklist without checking your own DISCOM’s current instructions.

1. Electricity Connection Documents

Latest paid electricity bill

Keep a clear copy of your latest paid bill. It should show the consumer name, address, CA or account number, connection category, sanctioned load where displayed and the electricity distributor.

Check that the name and address match the application. A mismatch can lead to a clarification request or delay.

Consumer or CA number

The CA number or consumer account number connects the solar system to the correct electricity meter. Enter it exactly as shown on your bill. Do not use a neighbour’s number, an old connection number or a number copied from a vendor message.

Registered mobile number and email

Keep access to the mobile number and email linked to the electricity connection or portal account. They may be used for OTPs, acknowledgements, application updates and clarification requests.

2. Identity and Address Proof

The DISCOM may ask for identity proof of the registered consumer or authorised applicant. Commonly accepted documents can include:

Aadhaar card.
PAN card.
Passport.
Driving licence.
Voter identity card.
Other identity documents accepted by the relevant authority.

Use a document with a name that matches the electricity account wherever possible. If the application is being submitted by an authorised representative, ask the DISCOM whether an authorisation letter or additional identity proof is required.

3. Ownership, Occupancy and Roof-Rights Proof

Solar panels are installed on a roof, terrace, balcony or elevated structure. The electricity connection alone may not prove that you have permission to use that installation area.

Depending on your property, the authority may ask for:

Registered sale deed.
Registered lease deed.
Allotment or possession letter.
Registered GPA or other accepted property document.
Occupancy proof.
Roof-use or terrace-rights proof.
Owner consent or NOC.
RWA or society resolution for a common roof.

Do not install panels on a shared roof without confirming roof rights and written permission. A later ownership or access dispute can affect maintenance, inspection and the meter connection.

Documents for Tenants

A tenant may need a current rent or lease agreement, the owner’s NOC and the owner’s identity proof. The exact requirement depends on the DISCOM and whether the electricity connection is registered in the tenant’s name.

Ask the owner to clearly confirm:

Permission to install the solar system.
Permission to use the roof or terrace.
Responsibility for removal or relocation at the end of the tenancy.
Ownership of the system and subsidy.
Responsibility for maintenance and net-metering changes.

Get the consent in writing before paying an installer.

Documents for Flats and Apartment Societies

A flat owner usually cannot assume that the building roof is available for private use. The application may require:

RWA or society permission.
Society resolution or authorised signatory letter.
Common-area roof or terrace-use proof.
Owner or association NOC.
Single-line diagram for the proposed connection.
Details of the meter and common-area load.
Structural or safety assessment where required.

For a common-area installation serving lifts, water pumps, lighting or EV chargers, the RWA may be the applicant or the authorised project owner rather than an individual resident.

4. Net-Metering Forms and Agreements

The application is not complete with identity and property documents alone. You may need the forms prescribed by your electricity distributor and DERC-related net-metering process.

These may include:

Net-metering application form.
Registration or feasibility form.
Connection agreement.
Declaration or undertaking.
Owner or tenant consent form.
Application-fee receipt, where applicable.
Electrical inspection or clearance documents, where required.

TPDDL publishes separate net-metering forms, including an application form, registration form, connection agreement and declaration. Check the current TPDDL net-metering forms.

BSES also publishes renewable-energy procedures, forms and post-installation document requirements. Check the BSES renewable-energy information.

5. Solar System Technical Documents

The DISCOM needs to understand what will be connected to its network. Your installer should prepare or provide the technical file.

Single-line diagram

A single-line diagram shows the solar panels, inverter, protection equipment, meter, isolation points and connection to the consumer installation. It should match the system actually installed.

Panel details

Keep the panel manufacturer, model, wattage, number of modules, serial numbers and applicable test or certification information.

Inverter details

Keep the inverter manufacturer, model, rated output, grid-connection specifications, certification or test documents and serial number.

System capacity

The proposed capacity should match the approved application and the equipment installed. Do not allow a vendor to change the capacity or inverter without checking whether the DISCOM must approve the change.

Protection and interlocking details

The technical file may need details of earthing, AC/DC protection, isolation, surge protection and anti-islanding or interlocking arrangements. These are safety matters, not optional paperwork.

6. Installer or EPC Documents

The installer may need to provide business and technical credentials, depending on the scheme and DISCOM process:

Vendor registration or empanelment details.
GST registration.
PAN or company details.
Electrical contractor licence, where required.
Authorisation letter or installer declaration.
Product datasheets and certification records.
Warranty and service documents.
Quotation and scope of work.

Do not accept “government-approved vendor” as a verbal claim. Ask which portal or programme recognises the vendor and check the information yourself.

7. Documents Required After Solar Installation

Post-installation documents are important for inspection, net-metering completion, commissioning and subsidy claims.

Depending on the route, keep:

Installation-completion certificate.
Project-completion report.
Joint completion or commissioning report.
Electrical testing or performance-ratio report.
Installation photographs.
Panel and inverter serial-number list.
Panel and inverter test sheets.
Warranty certificates.
Final bill of materials.
As-built drawing.
Net-meter installation record.
Insurance or performance-bank-guarantee documents, where required.
Remote-monitoring credentials and data-logger information, where applicable.

BSES post-installation checklists include claim, warranty, testing, completion, serial-number and installation-certificate documents for applicable applications. See the BSES post-installation checklist.

BSES, TPDDL and NDMC: Why the Checklist Can Differ

Delhi does not have one universal net-metering document list for every connection. Your electricity distributor may use its own portal, forms, application fee, inspection route and document naming.

BSES: Provides renewable-energy procedures, forms, helpline information and post-installation checklists.
TPDDL: Publishes its own application, registration, connection-agreement, declaration and feasibility checklist.
NDMC: Uses a separate solar and net-metering process for its electricity area.

Always identify the DISCOM from your electricity bill before downloading forms.

Documents for Solar Subsidy and Net Metering

Net-metering documents and subsidy documents overlap, but they are not identical. Subsidy processing may additionally require bank details, cancelled cheque, commissioning records, vendor declarations, product information and installation photographs.

Read our related guide on Documents Required for Solar Subsidy in Delhi.

For overall eligibility and subsidy conditions, see Delhi Solar Subsidy for Residential Homes.

When Should You Submit These Documents?

The documents are normally submitted in stages:

Before feasibility: electricity bill, consumer information, application form and initial identity or property documents.
During registration: connection agreement, declaration, technical proposal, diagram and equipment information.
Before or during installation: vendor agreement, approved capacity and required clearances.
After installation: photographs, serial numbers, testing, completion and installation certificates.
Before commissioning or subsidy release: net-meter records, commissioning report, bank details and final claim documents where applicable.

Do not upload every document to an unofficial form just because someone asks for it. Confirm the document requirement and upload location.

Common Reasons for Document Rejection

Consumer name does not match identity proof.
Wrong or old electricity bill uploaded.
CA or consumer number is incorrect.
Roof-rights proof is missing.
Tenant NOC does not include owner identity proof.
RWA authorisation is not signed by the correct person.
Scans are blurred, cropped or unreadable.
Technical diagram does not match the proposed equipment.
Panel or inverter model is incomplete.
System capacity differs from the approved capacity.
Required form is unsigned or not stamped where required.
Post-installation photographs do not show the complete system.
Bank details do not match the applicant.

How to Prepare a Clean Document File

Use the exact name shown on the electricity bill and identity proof.
Scan documents in colour and keep text readable.
Use the file type and size required by the portal.
Name files clearly, such as latest-electricity-bill.pdf.
Keep one folder for application documents and another for post-installation records.
Save the submitted forms and acknowledgement receipts.
Keep originals safely; submit copies unless the authority asks for originals.
Do not edit or alter official documents.
Take photographs with visible date or location information when requested.
Record every application number and complaint number.

How Net Metering Fits into the Subsidy Process

Net metering allows a grid-connected rooftop solar system to send eligible surplus electricity to the grid and record import and export through the applicable meter arrangement. It is not the same as solar installation or subsidy approval.

A typical workflow may include feasibility, registration, installation, net-meter application, inspection, meter installation, commissioning and subsidy documentation. The exact order and labels can vary by DISCOM.

For the broader online application process, read How to Apply for Solar Subsidy in Delhi Online.

How Much Does Documentation Cost?

Some documents, forms and online submissions may not have a separate charge, while an authority may charge an application or meter-related fee. Vendors may charge for drawings, site surveys, electrical work, civil work, notarisation, documentation support or corrections.

Ask the vendor to separate official fees from service charges. Do not pay an unexplained “document approval fee”.

How to Track a Net-Metering Application

Use the portal linked to your application and keep the application reference, CA number, registered mobile number, feasibility approval, net-metering request number, inspection record and commissioning report.

If your subsidy or rooftop-solar application appears stuck, read Delhi Solar Portal Application Status Check.

Cost and Capacity Before Applying

Before collecting documents, confirm that the proposed capacity matches your electricity use, roof area and budget. A larger system may require additional technical documents and a more detailed proposal.
