We get this question all the time. And honestly—it’s a blessing in disguise. In Tamil Nadu, the solar market is booming, and where there’s money, shortcuts follow. A “cheap quote” is never magic—it usually hides compromises in safety, compliance, or longevity.
Remember: Solar is a 25-year investment. If the installer cheats you today, you’ll pay for it for decades.
Here are the 7 Dirty Tricks unscrupulous installers use in 2026—and why you’ll end up paying double later:
1. The “Sticker” Scam (Fake DCR Panels)
The PM Surya Ghar subsidy requires DCR (Domestic Content Requirement) panels—i.e., Indian cells and modules.
The Scam: Cheap imported panels (20% cheaper) with a fake DCR sticker.
The Risk: TNEB inspection fails, subsidy rejected. You lose ₹78,000 to save ₹10,000 upfront.
Our Fix: We provide original factory datasheets and serial numbers for verification before installation.
2. The “Paint Job” Structure (Fake Galvanizing)
The Scam: Quote says “Galvanized Structure,” but the installer uses cheap MS pipes painted silver.
The Risk: In coastal Tamil Nadu, paint peels in 6 months. By Year 4, the structure is dangerously weak.
Our Fix: Hot-Dip Galvanized steel (80 microns) bonded at 450°C—impossible to peel off.
3. Thin Wires (The Fire Hazard)
The Scam: Using 2.5 sq.mm DC cables instead of the proper 4–6 sq.mm.
The Risk: Wires heat up, lose 10% of power, insulation melts, and DC Arc Fires can occur.
Our Fix: Polycab/Siechem 4 sq.mm+ UV-protected solar cables.
4. The “Ghost” Warranty
The Scam: “25-year warranty” from a new vendor who disappears in a few years.
The Risk: Inverter maintenance in Year 3? No response. You’re left with an orphaned system.
Our Fix: We have a physical office in Cuddalore, and our support team answers every call.
5. Hidden TNEB Costs
The Scam: The quote hides fees for Net Meter, official liaisoning, and safety letters.
The Risk: After paying the advance, they add ₹10,000–₹15,000 extra.
Our Fix: Our pricing is all-inclusive, from application to commissioning. No surprises.
6. Under-Sized Earthing
The Scam: 3ft iron rod instead of proper 2-meter chemical earthing kit.
The Risk: Lightning strikes can fry your ₹50,000 inverter. Warranty does not cover lightning damage.
Our Fix: 3 separate earthing pits (DC, AC, LA) filled with Backfill Compound (BFC), resistance <5 Ohms.
7. Mixed or B-Grade Panels
The Scam: Using factory-rejected panels with micro-cracks to cut cost.
The Risk: Works fine Year 1, but micro-cracks grow. Output drops by 50% in 5 years.
Our Fix: Only A-Grade panels, sourced directly from authorized distributors.
How to Protect Yourself: The 2026 Checklist
Before signing any agreement, verify:
- ALMM Certificate: Ensure the panel brand is government-approved.
- Structure Sample: Inspect a piece of the actual mounting pipe.
- Reference Sites: Visit a 3-year-old installation. Old sites show real durability.
Rule of Thumb: Don’t bet your roof on the lowest bidder. Quality is remembered long after the price is forgotten.
