Solar Scams in India: The Red-Flag Handbook
India’s solar boom has attracted brilliant engineers — and a long tail of operators who profit from what buyers don’t know. This handbook lists the traps we see most, each with the one verification step that defuses it. Ten minutes here protects a lakh-rupee decision.
Why Solar Attracts Scams
Three ingredients make rooftop solar fertile ground for bad actors: buyers purchase once in a lifetime (no repeat-purchase learning), quality failures surface years later (monsoon three, not week three), and a government subsidy adds urgency and authority that is easy to fake. None of this makes solar risky — it makes verification valuable. Every trap below dies on contact with a single document check.
Subsidy & Paperwork Traps
The subsidy is the most impersonated element of Indian solar. The ground truth is simple: the PM Surya Ghar subsidy is fixed (₹30,000/kW for 2 kW, ₹18,000 for the third, max ₹78,000), paid directly into your bank account by the government after commissioning — never routed through a vendor.
- RED FLAG 1 — "Free solar under government scheme": nothing is free; the subsidy covers roughly 30–40% of a 3 kW system. Anyone promising ₹0 cost is monetising you some other way.
- RED FLAG 2 — "Pay us, we adjust the subsidy": subsidy money never flows through vendors. A quote that "includes" subsidy as a discount they administer is a fiction you can’t audit.
- RED FLAG 3 — "Subsidy approved" WhatsApp/SMS links demanding a processing fee: the national portal charges no processing fee. These are phishing — verify only at pmsuryaghar.gov.in.
- RED FLAG 4 — Vendor "will register later": feasibility approval must precede installation. Systems installed before portal approval can lose eligibility entirely.
Equipment Traps
Equipment fraud thrives because module labels all look alike. Your defence is the paper trail: model numbers in the quotation, ALMM verification, and serial-label checks at delivery.
- RED FLAG 5 — "MNRE-approved panels" without a model number: MNRE approves models, not brands. Verify the exact model on the current ALMM list; for subsidy, confirm DCR in writing.
- RED FLAG 6 — Non-DCR modules on a subsidised system: discovered at inspection, denied at your cost. Put subsidy eligibility contractually on the vendor.
- RED FLAG 7 — B-grade or refurbished panels: mismatched serial labels, missing BIS marks, or "export surplus" stories. Check serials against the invoice on delivery day, panel by panel.
- RED FLAG 8 — Poly panels priced as premium: polycrystalline is obsolete; any quote built on it is clearing old stock at your expense.
- RED FLAG 9 — The vanishing inverter brand: a premium panel headline with an unbranded inverter buried in the BOM. The inverter fails first — its brand and local service network deserve the most scrutiny, not the least.
Performance & Pricing Traps
Generation claims are where honest physics gets stretched into sales physics. Anchor on one number: across most of India, 1 kW produces about 4 units/day annual average — roughly 1,400–1,700 kWh/kWp/year. Claims meaningfully above that band are either assuming Rajasthan sun on your Kerala roof, or lying.
- RED FLAG 10 — "5–6 units per kW daily, guaranteed": that is 1,800–2,200 kWh/kWp/yr — beyond even Ladakh for fixed rooftops. Demand the assumption sheet (PSH, PR, tilt) behind any generation promise.
- RED FLAG 11 — The too-cheap quote: at market ₹/W, someone quoting 30–40% below the pack is recovering it via structure steel weight, cable gauge, missing DCDB/ACDB/earthing, or equipment substitution. Compare BOMs line by line, not totals.
- RED FLAG 12 — 80–100% advance payment: standard practice is a modest booking advance with milestone payments (delivery, installation, commissioning). Large advances to thin companies are how buyers become creditors.
Installation & After-Sales Traps
The cheapest place to cut a solar quote is where you can’t see it: structure gauge, anchoring, and the service organisation that is supposed to answer in year six.
- RED FLAG 13 — Structure amnesia: no wind-load design, thin unbranded sections, expansion bolts hammered into your slab. Ask for the structure spec (material, coating microns, wind rating) and the waterproofing method for every roof penetration — in writing.
- RED FLAG 14 — Warranty by brochure: "25-year warranty!" conflates panel performance warranty (manufacturer) with workmanship warranty (installer, typically 1–5 years). Get both in writing, plus the PM Surya Ghar-mandated 5-year vendor maintenance responsibility.
The 10-Minute Defence Kit
You do not need to become an engineer. You need five documents and three verifications before any advance leaves your account:
Before paying anything, hold in hand:
- Itemised quotation: model numbers for panels and inverter, structure spec, cable sizes, protection boxes, earthing count
- ALMM verification of the exact panel model (and DCR confirmation in writing, if subsidised)
- Vendor’s registration status on the national portal / DISCOM empanelment
- Payment schedule tied to milestones, with subsidy-eligibility responsibility on the vendor
- Warranty matrix: panel product + performance, inverter, structure, workmanship, and who services each
If You’ve Already Been Caught
Document everything (quotation, payments, chats, photos of installed equipment), file a written complaint with the vendor first, then escalate: your DISCOM’s consumer grievance forum for subsidy/installation issues, the National Consumer Helpline (1915) and consumer commission for financial recovery, and cybercrime.gov.in for phishing-based subsidy fraud. Complaints with serial numbers and paper trails succeed; verbal histories don’t — which is one more argument for the defence kit above.
Frequently Asked Questions
- Is the "free solar panel government scheme" real?
- No scheme gives free rooftop solar to general households. PM Surya Ghar subsidises roughly 30–40% of a 3 kW system (max ₹78,000), paid to your bank account after commissioning — never through a vendor, never for a "processing fee".
- How much advance payment is normal for rooftop solar?
- A modest booking amount with milestone-linked payments (delivery, installation, commissioning) is standard. Treat demands for 80–100% upfront as a serious red flag, especially from young companies.
- How do I verify a solar vendor is genuine?
- Check portal/DISCOM registration, verify the quoted panel model on the ALMM list, ask for reference installations you can call, and confirm the inverter brand’s service presence in your city. Ten minutes of checks filters most bad actors.
- What is a realistic generation promise per kW in India?
- About 4 units/kW/day annual average — 1,400–1,700 kWh/kWp/year depending on region. Promises of 5–6 units/kW/day are the single most common inflated claim in Indian solar sales.
