Solar Panel Subsidy in Tamil Nadu: Step-by-Step Guide

```html

Introduction

Tamil Nadu has expanded support for residential rooftop solar by combining Central Financial Assistance under PM Surya Ghar: Muft Bijli Yojana with an additional state subsidy. The current Tamil Nadu Solar Rooftop Portal states that eligible households can receive up to ₹1 lakh in combined assistance.

Understanding the solar subsidy in Tamil Nadu involves more than knowing the subsidy amount. Homeowners need to check eligibility, register through the correct portal, select an eligible vendor, complete installation, and follow the inspection and commissioning process.

Here is a step-by-step guide to the current process for applying for a solar subsidy in Tamil Nadu.

How Much Solar Subsidy Is Available in Tamil Nadu?

The Central Government provides assistance based on eligible rooftop solar capacity, while Tamil Nadu provides an additional state top-up. The current state portal lists the following structure:

The state portal states that its subsidy covers residential rooftop systems up to 10 kW, subject to the applicable eligibility conditions. It also specifies that DCR-compliant, ALMM-listed modules must be used and installed through TEDA-empanelled vendors.

Who Is Eligible for Solar Subsidy in Tamil Nadu?

The requirements of solar subsidy eligibility in Tamil Nadu primarily apply to eligible residential consumers installing qualifying grid-connected rooftop solar systems.

Before applying, homeowners should confirm:

• The electricity connection is eligible for the scheme.
• The applicant details correspond with the electricity connection.
• The proposed rooftop system meets the programme's technical requirements.
• The selected vendor is empanelled through the applicable process.
• The installation can be completed according to TNPDCL and scheme requirements.

The current portal also specifies that the state subsidy is released after installation, net metering, commissioning, and central CFA disbursement, subject to the Tamil Nadu solar scheme's eligibility conditions.

How to Apply for Solar Subsidy in Tamil Nadu?

The solar subsidy in Tamil Nadu follows a connected process between the national PM Surya Ghar portal and Tamil Nadu's state rooftop-solar system.

Step 1: Register on the PM Surya Ghar Portal

Begin by registering through the national PM Surya Ghar portal using the details associated with your electricity connection.

The Tamil Nadu process begins with the central application rather than a separate state-subsidy application.

You will generally need your:

• Electricity consumer number
• Registered mobile number
• Email address
• Basic applicant details

Step 2: Submit Your Rooftop Solar Application

Enter the required electricity connection and consumer information and submit the application.

The application is then processed for the applicable feasibility approval through the distribution utility. Tamil Nadu's official process includes acknowledgement and feasibility before the vendor and installation stages.

Step 3: Select an Empanelled Vendor

Once the required approval is received, select an applicable empanelled vendor through the prescribed process.

The vendor and consumer can finalise the system configuration and installation requirements. The state portal specifically requires eligible installations to use DCR-compliant, ALMM-listed modules and TEDA-empanelled vendors.

Step 4: Install the Rooftop Solar System

The selected vendor installs the approved system according to the applicable technical requirements.

The final system configuration can depend on the property's electricity consumption, available roof space, solar potential, and selected equipment. For Tamil Nadu rooftop solar subsidy, homeowners should ensure that the installed system corresponds with the approved application and scheme requirements.

Step 5: Complete Metering, Inspection and Commissioning

After installation, TNPDCL completes the applicable meter-related, inspection, and commissioning stages.

The Tamil Nadu portal describes the process as including net-meter installation, inspection, commissioning, and connection before the central subsidy claim is processed.

Step 6: Receive the Central Subsidy

Following successful installation and verification, the Central Financial Assistance is processed under PM Surya Ghar.

The MNRE framework states that CFA is transferred to the consumer's account after successful installation by an empanelled vendor and verification by the relevant DISCOM.

Step 7: Receive the Tamil Nadu State Top-Up

This is an important part of the current process. Once the central subsidy is credited, the Tamil Nadu state portal receives the relevant disbursement information against the PM Surya Ghar application.

According to the Tamil Nadu Solar Homes Portal, no second application is required for the state top-up. The portal then verifies eligibility, commissioning, and bank details before the applicable state subsidy is transferred through Direct Benefit Transfer.

What Should You Check Before Applying?

Before applying for the solar subsidy in Tamil Nadu, review these points:

• Electricity Connection: Confirm that your consumer connection meets the applicable requirements.
• System Capacity: Select a capacity based on electricity consumption and roof conditions.
• Vendor: Choose an empanelled vendor through the prescribed process.
• Module Compliance: Check that the proposed modules meet the DCR and ALMM requirements.
• Net Metering: Understand the applicable metering and grid-connection process.
• Bank Details: Ensure the account information required for DBT is accurate.
• Installation Documents: Retain invoices, photographs, and commissioning records.

These checks can help prevent avoidable delays during installation and subsidy processing.
