TNEB / TNPDCL Solar Vendor List: How to Check (2026)

Short answer: registered solar vendors for the Tamil Nadu rooftop subsidy are listed on the official PM Surya Ghar portal (pmsuryaghar.gov.in), filtered by state and district. You must use a vendor from that list: if an unregistered installer does the work, you can lose the full ₹1 lakh subsidy. But registration only means a vendor is allowed to install subsidy systems; you still need to check quality, office, reviews and warranties before paying any advance.

Portal steps as of October 2026. Screens change; your vendor can show you their registration on the portal.

Common Questions About the Vendor List

"Some companies near me are not on the list." Many electricians and shops sell panels but are not registered for the subsidy. Their systems may work, but you will not get the subsidy through them.

"Can a vendor from another district install for me?" Vendors register for areas they serve. Prefer a vendor close enough to service your system quickly after installation, because inverter or wiring faults need a visit.

"The list shows ratings. Do they matter?" Ratings help, but also read Google reviews and talk to a past customer.

What a Registered Vendor Should Do for You

Free site visit, shade check and sizing from your bills.
Written, itemised quote with DCR model and warranties.
Help with portal registration and documents.
Installation with proper structure, cabling and earthing.
Upload of work completion details and panel serials.
Follow-up with TNPDCL for inspection and net meter.
Support until the subsidy is credited, and service afterwards.

Red Flags Even If a Company Is Registered

They ask for full payment before material arrives.
They avoid naming the exact panel model or say "DCR will be arranged later".
They promise a "guaranteed zero bill" without seeing your bills.
They cannot show any recent installation or customer you can call.
They tell you the subsidy is assured before feasibility approval.

How to Compare Two Registered Vendors

Compare	Vendor A	Vendor B
Distance from your home
Installations in your district
Panel model and DCR proof
Inverter brand and warranty
Structure and earthing
Total price and price per watt
Who follows up for net meter and subsidy

Fill this in after each site visit; the right choice is usually clear by the end. Choose the vendor who answers every row clearly in writing, even if their price is slightly higher, because a well-installed system will run for 25 years.

Frequently Asked Questions

Where can I find the solar vendor list for Tamil Nadu?

Registered vendors for the rooftop subsidy are listed on the official PM Surya Ghar portal (pmsuryaghar.gov.in) for your state and district. You also choose a vendor from that list during your application.

Why must I use a registered vendor?

Only systems installed by vendors registered on the PM Surya Ghar portal can receive the subsidy. If an unregistered installer does the work, you can lose both the ₹78,000 central subsidy and the ₹22,000 Tamil Nadu top-up.

Is every vendor on the list equally good?

No. Registration means the vendor is allowed to install subsidy systems; it does not guarantee quality. Also check their office, past installations, reviews, structure and earthing standards, and written warranties.

Is Surya's Solar a registered vendor?

Yes. Surya's Solar is registered on the PM Surya Ghar portal with 150+ installations in Cuddalore district, and serves Cuddalore district and Puducherry.

Can I change my vendor after applying?

The portal allows a vendor to be chosen for your application. If you need to change before installation, check the option on the portal or ask your TNPDCL section office; do it before any installation work starts.

Does a vendor rating on the portal guarantee good service?

No. Ratings help, but also read recent Google reviews with photos, visit the office and speak to one past customer near you before booking.

How much advance should I pay a solar vendor?

A fair schedule is a moderate advance on order, the main payment when material is delivered and the balance after installation and testing. Avoid paying the full amount before any material reaches your home.
