Solar Vendors in Hyderabad: How to Find a Verified Installer

Choosing among Solar Vendors in Hyderabad is the highest-stakes decision in your rooftop solar journey. Panels and inverters carry standard warranties, but installation quality, honest paperwork and after-sales service vary widely from one installer to the next. A good vendor in Hyderabad handles everything: a shadow-free roof design, TGSPDCL net-metering approval, subsidy filing on the national portal, and final grid commissioning. A careless one can leave you with a system that underproduces and a subsidy application stuck for months. This guide teaches you how to find and verify registered vendors in Hyderabad through the official portal, which documents to demand before signing, the red flags that should make you walk away, and the exact subsidy and loan math for homes here in 2026. We name no vendors on this page, because trust should be verified, not advertised.

How to Find Verified Solar Vendors in Hyderabad

A verified vendor in Hyderabad is one registered on the national PM Surya Ghar portal (pmsuryaghar.gov.in) and recognised by Telangana State Southern Power Distribution Company Limited (TGSPDCL). Only installations by such registered vendors, using DCR-compliant equipment, qualify for the central subsidy of up to ₹78,000. Registration matters because the subsidy is released only after the DISCOM inspects and commissions the system, and the DISCOM only commissions work done by vendors it recognises.

Start your search on the portal, not on Google ads. The portal list is the single source of truth for who is allowed to install a subsidised system. When you meet vendors from areas like the busy residential belts of Hyderabad, ask each one the same set of questions: how many TGSPDCL net-metering applications they filed in the last year, what their average approval time was, and whether they handle the full subsidy filing or expect you to do it. Consistent answers are a good sign; vague answers are not.

Also check how long the company has operated under its current name. A vendor with five years of local installations and a service office in Hyderabad is far more likely to honour a workmanship warranty than a newly formed team with no local address. Ask for two or three customer references in Hyderabad whose systems are at least a year old, and actually call them.

Step-by-step: finding vendors on the national portal

1. Go to pmsuryaghar.gov.in and register as a residential consumer using your TGSPDCL consumer (service connection) number.
2. In the vendor section, filter the installer list by state (Telangana) and then by the Hyderabad district so you see vendors who actually work in your area.
3. Open each shortlisted vendor profile and check the registration status, year of empanelment, and the contact details shown on the portal.
4. Cross-check that the vendor is recognised by TGSPDCL (Telangana State Southern Power Distribution Company Limited), because net-metering approval in Hyderabad runs through the DISCOM, your local electricity distribution company.
5. Invite three or four vendors for a free site survey. Ask each one for a shadow analysis of your roof, not just a price quote.
6. Before signing, confirm in writing that the panels are DCR (made with Indian-made solar cells, required for subsidy) and that the vendor will file your net-metering and subsidy paperwork.

Documents and Credentials to Verify Before Signing

A trustworthy installer hands over paperwork without being asked twice. Before you sign anything in Hyderabad, collect these documents and read them fully.

• DCR declaration for the panels: DCR means Domestic Content Requirement, and it certifies that the solar panels are made with Indian-made solar cells. Only DCR panels qualify for the PM Surya Ghar subsidy. Ask the vendor to name the panel make and model in writing and confirm DCR status.
• MNRE-compliant equipment: modules should come from the ALMM list (the government Approved List of Models and Manufacturers). The inverter should carry standard certifications and a clear 5-year product warranty.
• TGSPDCL empanelment or registration proof: ask for the vendor's registration letter or proof of empanelment with Telangana State Southern Power Distribution Company Limited. A vendor who cannot show this may still be a good electrician, but your subsidy and net-metering approval will be at risk.
• GST invoice in your name: the invoice must show the system capacity in kW, panel and inverter make and model, and GST separately. You need this invoice for the subsidy claim.
• Warranty cards: typical industry practice is a 25-year panel performance warranty, a 5-year inverter warranty, and a 5-year workmanship warranty covering the installation itself. Get all three in writing, with the vendor's service contact printed on them.
• A written contract: it should state the system size, equipment makes and models, total price, payment schedule linked to milestones (not dates), the installation timeline, and who is responsible for net-metering filing, inspection, and subsidy application.

Keep a single folder, physical or digital, with copies of every document. If a dispute arises later, this folder is your evidence.

Red Flags: When to Walk Away

Good vendors in Hyderabad are patient with questions. Walk away when you see any of these signs, no matter how attractive the price sounds.

• 100% advance demanded upfront: a standard schedule is 10 to 20% as booking advance, the bulk on material delivery, and the balance after commissioning. Anyone asking for the full amount on day one is a risk.
• Subsidy promised with non-DCR panels: if the quote uses imported (non-DCR) panels but the vendor still promises you the PM Surya Ghar subsidy, the promise is false. Subsidy needs DCR panels, no exceptions.
• No help with net metering: net metering, a two-way meter that credits you for extra power you send to the grid, is essential for savings. A vendor who says "you handle the DISCOM paperwork" is leaving the hardest part to you.
• No written warranty: verbal promises about 25-year panel life mean nothing. Insist on printed warranty cards.
• Pressure tactics: "this price is only valid today" or "subsidy ends this week" are sales tricks. The central subsidy slabs are published and stable.
• A quote far below market: an indicative 3kW rooftop system in 2026 costs roughly ₹1.8 to ₹2.0 lakh before subsidy. A quote of ₹1.2 lakh means corners are being cut, usually in the mounting structure, wiring, or panel quality.

TGSPDCL Net Metering Process in Hyderabad

Net metering in Hyderabad runs through TGSPDCL, the Telangana State Southern Power Distribution Company Limited: you apply for technical feasibility, install the system through a registered vendor, and TGSPDCL then installs a bi-directional meter that credits your bill for surplus power you export to the grid.

The practical route is to apply on pmsuryaghar.gov.in with your TGSPDCL consumer number. TGSPDCL checks technical feasibility through your local division office, which confirms that the nearby transformer and feeder can accept your system capacity. Most residential systems of 1 to 5 kW clear this step quickly; larger systems may need a transformer-capacity check.

Once feasibility is approved, your vendor installs the plant and submits the work completion report. TGSPDCL then inspects the installation, installs the net meter, and issues the commissioning certificate. Keep your vendor responsible for every one of these steps in the written contract.

If the process feels confusing, TGREDCO (the Telangana renewable energy agency) runs Seva Setu guidance camps that explain the paperwork to homeowners. Attending one before you sign with a vendor can save you from common filing mistakes.

Subsidy and Loan Math for Hyderabad Homes

Under the PM Surya Ghar Muft Bijli Yojana, the central financial assistance (CFA), the government subsidy credited directly to your bank account after commissioning, follows fixed slabs: ₹30,000 for 1 kW, ₹60,000 for 2 kW, and ₹78,000 for 3 kW and above. The money arrives through DBT (Direct Benefit Transfer) after your DISCOM inspects the system and the details are uploaded to the national portal.

Telangana currently offers no state top-up over the central subsidy, so a Hyderabad home should plan on the central slabs only: ₹30,000 for 1 kW, ₹60,000 for 2 kW, and ₹78,000 for 3 kW or more. Any vendor promising an extra state bonus is misinformed or misleading you, so ask them to show the government order.

A worked example helps. Take a typical 3 kW system quoted at ₹1.9 lakh before subsidy. With the ₹78,000 central CFA and no state top-up, your net cost lands near ₹1.12 lakh. A 3 kW plant in this region typically generates 12 to 15 units a day, which for most homes wipes out the bulk of the grid bill and pays back the net investment in roughly four to six years.

If you need finance, the national rooftop solar loan programme offers up to ₹2 lakh at around 5.75% per year, with a tenure of up to 10 years and no collateral required for loans up to ₹2 lakh. Apply through the Jan Samarth portal. As an indication, a ₹2 lakh loan at 5.75% over 10 years works out to an EMI of roughly ₹2,200 per month, while a 3kW system in a sunny Hyderabad home can cut the monthly bill by a similar or larger amount, so the system often pays for itself from month one.
