Solar Scams to Avoid in Hyderabad
Red Flags, Fraud Patterns, and How to Buy Solar Safely in 2026
Updated May 2026 | By Sri Ishaan Solar Team
Solar adoption in Hyderabad has grown rapidly — and with it, a rise in fraudulent installers, misleading subsidy claims, and substandard equipment sold under reputable brand names. Before you sign any solar contract or pay any advance, read this guide. We have compiled the most common scams reported by customers who came to us after bad experiences elsewhere.
Scam 1: Unlicensed Installers Claiming "Government Approved" Status
Many fly-by-night solar vendors in Hyderabad present themselves as "government-approved" or "MNRE-empanelled" installers without any verifiable registration. This matters because:
- Only TGREDCO-registered installers can process PM Surya Ghar subsidy applications in Telangana
- Using an unregistered installer means your subsidy application will be rejected
- If the installer disappears after installation, you have no recourse
How to verify: Visit tgredco.telangana.gov.in/SolarLinks.aspx and search for the installer's TGREDCO registration number. Ask for this number in writing before signing anything. Sri Ishaan Solar's registration: TSRE260936.
Scam 2: Inflated Subsidy Claims
The most widespread misinformation in Hyderabad solar sales is the claim of combined central + state subsidies totalling ₹1.38 lakh or more. Here are the actual facts:
- PM Surya Ghar (PMSG) subsidy maximum: ₹78,000 for 3kW and above systems
- Telangana state subsidy top-up: None. The state government does not add to the central subsidy.
- Any installer claiming ₹1 lakh, ₹1.38 lakh, or ₹2 lakh subsidy is either misinformed or deliberately misleading you.
The inflated subsidy claim is used to make a higher-priced system appear cheaper after "subsidy." Verify subsidy rates at the official PM Surya Ghar portal: pmsuryaghar.gov.in.
Scam 3: Non-ALMM Panels Sold as "Tier 1"
The term "Tier 1" in solar has no official regulatory definition — it is a marketing term used by a financial analytics firm to rate manufacturers' bankability. Any installer can call their panels "Tier 1" regardless of quality. The regulatory standard that actually matters is ALMM certification.
ALMM (Approved List of Models and Manufacturers) is maintained by MNRE and lists panels that meet Indian quality standards. Only ALMM-listed panels are eligible for PM Surya Ghar subsidy processing.
How to verify: Ask for the exact panel model number and manufacturer. Search it on the MNRE ALMM list at mnre.gov.in. If it is not there, your subsidy application will be rejected and you have no quality assurance on the panels.
Scam 4: Suspiciously Low Pricing
The current market rate for quality on-grid residential solar in Hyderabad is approximately ₹50,000–70,000 per kW (gross, before subsidy). If you receive a quote below ₹40,000/kW, something is being compromised:
| Price Level | What Is Likely Being Compromised |
|---|---|
| Below ₹40,000/kW | Non-ALMM panels, untested inverter brands, no earthing, no MC4 connectors, no post-installation AMC |
| ₹40,000–50,000/kW | Budget inverter, basic mounting structure, limited warranty support |
| ₹50,000–70,000/kW | Market-standard quality: ALMM panels, reputed inverter, proper installation |
A system installed with substandard components may generate 20–30% less power than specified and fail within 3–5 years — long before payback is achieved.
Scam 5: No Written Specification in the Quotation
Reputable installers always provide a detailed written quotation that includes:
- Exact panel brand, model number, and wattage per panel
- Inverter brand and model number
- Mounting structure type and material
- Cable specifications
- Warranty terms (panel performance warranty, inverter warranty)
- Installer's GSTIN on the invoice
If a vendor gives you only a lump-sum price without component details, refuse. You have no basis to compare quality and no legal recourse if the installed components differ from what was promised verbally.
Scam 6: Excessive Advance Demand
Some fraudulent operators disappear after collecting a large advance payment. Standard payment structure for legitimate solar installations in Hyderabad:
- 10–20% advance at order placement (to begin procurement)
- 40–60% on delivery of materials to site
- Remaining balance on commissioning and net meter installation
Never pay more than 30% before material arrives at your site. Never pay 100% before the system is running and the net meter is installed. Sri Ishaan Solar follows this structure transparently.
Red Flags Checklist
Walk away if an installer:
- Cannot provide their TGREDCO registration number
- Claims more than ₹78,000 subsidy for any residential system in Telangana
- Cannot name the exact panel model and show it on the MNRE ALMM list
- Quotes below ₹40,000 per kW for a complete installed system
- Refuses to provide a written quotation with GSTIN
- Demands more than 30% payment before materials arrive
- Has no physical office address you can verify
- Pressures you to sign quickly or offers "today only" discounts
How to Verify a Solar Installer in Hyderabad
- TGREDCO registration: Check tgredco.telangana.gov.in/SolarLinks.aspx
- GST registration: Verify their GSTIN on the GST portal at gstin.gov.in. An unregistered business cannot file subsidy applications.
- Physical address: Ask for their registered office address and visit it or verify it on Google Maps.
- References: Ask for 2–3 recent customers in your area and actually call them.
- Panel ALMM status: Search the proposed panel model on mnre.gov.in.
- Multiple quotes: Get at least 2–3 detailed written quotations and compare specifications, not just price.

Request a Verified Quote on WhatsAppFrequently Asked Questions
How do I check if a solar subsidy claim is real?
Go to pmsuryaghar.gov.in for current subsidy rates. In Telangana, the maximum residential subsidy is ₹78,000 for a 3kW+ system. Telangana has no additional state top-up. Any claim above this is false.
What is ALMM and why does it matter?
ALMM is MNRE's Approved List of Models and Manufacturers — the official government quality list for solar panels in India. Only ALMM-listed panels are eligible for PM Surya Ghar subsidy. Non-ALMM panels are often Chinese-origin products without Indian testing certification. Verify at mnre.gov.in.
Should I get multiple solar quotes?
Always. Get at least 2–3 written quotes specifying the same or comparable panel wattage and inverter type. Compare the specification sheets, not just the price. A 20% lower price almost always means a corner cut somewhere — panel quality, inverter brand, mounting structure grade, or post-installation service.
How do I verify a solar installer is TGREDCO registered?
Visit tgredco.telangana.gov.in/SolarLinks.aspx and search for the installer's name or registration number. This takes less than 2 minutes and can save you from a major financial loss.
What advance payment is reasonable for solar installation?
10–20% at order confirmation is standard. Never pay more than 30% before materials are delivered to your site. Pay the balance on commissioning. Any demand for 50%+ upfront before work begins is a serious red flag.
