Solar Installation Kerala: Required Documents and Approvals

However, installing a solar energy system involves more than just buying and setting up panels. To ensure your system is legally compliant and eligible for benefits like net metering and government subsidies, you must obtain certain approvals and submit the correct documentation.

1. Understanding the Approval Process

In Kerala, the solar installation approval process is largely regulated by two bodies:

• KSEB (Kerala State Electricity Board) – for net metering and grid connection.
• ANERT (Agency for Non-conventional Energy and Rural Technology) – for vendor registration and subsidy coordination (if applicable).

The process generally includes:

1. Submitting an application to KSEB for grid connectivity and net metering.
2. Getting system design and vendor details approved.
3. Completing installation as per standards.
4. Final inspection and commissioning.
5. Applying for subsidy (if eligible).

Each of these steps requires specific documents, which we detail below.

2. Documents Required for Grid-Connected Solar Installation

If you're installing an on-grid solar system with net metering, here are the standard documents you need:

a. Application Form

A filled-in application form is submitted to the KSEB through their online portal or relevant local office. This form includes basic personal details, system capacity, and type of solar system proposed.

b. Identity Proof

Any one of the following:

• Aadhar Card
• Passport
• Voter ID
• Driving License

This is used to verify the applicant’s identity.

c. Address Proof

This confirms that the applicant is the resident or owner of the premises where the installation will take place. Documents include:

• Electricity bill
• Property tax receipt
• Ration card

d. Recent Electricity Bill

A copy of your latest electricity bill (from KSEB) is required to confirm the consumer number and load sanctioned.

e. Ownership Proof or Consent Letter

If the applicant is the owner of the property, property ownership proof (such as a title deed or tax receipt) must be submitted.

If the applicant is a tenant, a No Objection Certificate (NOC) or consent letter from the property owner is required.

f. System Design and Technical Specifications

A layout or design of the proposed solar PV system, including:

• Panel make and model
• Inverter type and capacity
• Mounting structure details
• Wiring and protection components

This design should be prepared by the solar installer or vendor.

g. Vendor/Installer Details

If you are applying for subsidy or want to ensure compliance, the installer must be registered with ANERT and/or empaneled by MNRE (Ministry of New and Renewable Energy).

You may need to provide:

• Vendor company name and contact
• Registration number or empanelment ID
• Installation agreement or invoice

3. Additional Documents for Net Metering

Kerala’s net metering policy allows consumers to feed excess electricity into the grid and receive bill credits. To get a net meter installed, you’ll typically need:

• Net metering agreement form (provided by KSEB)
• Declaration form from the consumer
• Wiring diagram for solar system integration with grid
• Safety certificate from the licensed electrical contractor

KSEB may also conduct an on-site inspection before approving the connection.

4. Approvals from KSEB

After submitting all required documents, KSEB reviews the application. Key approvals include:

a. Technical Feasibility Approval

This checks whether the existing grid infrastructure can support your proposed solar system. Approval depends on your sanctioned load and the transformer capacity in your area.

b. Permission for Installation

Once feasibility is confirmed, you will receive approval to proceed with the solar system installation. Installation should follow KSEB’s technical standards.

c. Post-Installation Inspection

After system setup, KSEB conducts a site inspection. They check:

• Proper mounting and wiring
• Earth grounding
• Protection systems (MCBs, SPD, isolators)
• Compliance with the sanctioned system design

If the system passes inspection, a bi-directional net meter is installed.

d. Commissioning Report

A report is issued once the system is tested and found compliant. This marks the official grid connection date for your solar system.

5. Documents Required for Subsidy (if applicable)

If you're applying for a subsidy under the PM Surya Ghar Muft Bijli Yojana or other government schemes, these documents are required in addition to the above:

• Bank account details (cancelled cheque or passbook copy)
• PAN card (for subsidy transfer)
• System installation report signed by the vendor and applicant
• Photographs of installed system with applicant present
• Completion certificate from the installer
• Uploads on the National Portal for Rooftop Solar (if subsidy applied online)

Subsidy is transferred directly to the consumer's bank account after verification.

6. Timeframe for Approvals

While timelines may vary by location, the general process follows:

Delays can occur if documents are incomplete or if installer/vendor is not registered.

7. Importance of Working with Certified Installers

Working with an experienced and certified solar installer is highly recommended. They are familiar with the documentation and approval process and can guide you through each step without delays or errors. Moreover, only installations done by MNRE-empaneled vendors are eligible for subsidies.
