Avoid Solar Scams: What to Check Before Hiring an Solar Installer in India
Rooftop solar can slash your electricity bills for 20+ years but only if it’s installed properly. A poorly done setup can leave you with faulty panels, delayed subsidies, rejected net metering applications, and no one to call when something breaks.
Unfortunately, in India’s fast-growing solar market, not all installers are equal. Some are genuine professionals. Others are out to make a quick buck, often vanishing once your system is paid for.
Here’s how to make sure you pick a reliable, trustworthy solar installer and avoid the common traps.
Step 1: Check If They’re Approved by MNRE or a State Agency
Before anything else, ask this: Are you listed as an MNRE-approved vendor or state-authorised installer?
This matters because:
- Only approved installers can help you get the central government subsidy
- These vendors are verified by the Ministry of New and Renewable Energy or your state nodal agency (like GEDA, TEDA, HAREDA)
You can verify on: https://pmsuryaghar.gov.in
Also check:
- Do they have a valid GSTIN and business registration?
- Is there a real address on their invoice?
If they can’t provide these, walk away.
Step 2: Ask What Work They’ve Already Done Not Just What They Claim
Don’t settle for words like “we’ve done 100+ installations.” Ask for:
- Site photos (before/after)
- Contact details of 1-2 past customers
- Project sizes similar to yours (e.g., 3 kW for a 2BHK)
A vendor who truly knows what they’re doing will have no problem showing you real examples.
Prioritize companies with at least 3-5 years of installation experience they’re more likely to stick around after installation.
Step 3: Read Solar Installer Online Reviews But Learn to Spot the Fakes
Start with:
- Google Reviews
- Justdial or Sulekha listings
- Local Facebook groups or forums
Look for patterns like:
- Comments on after-sales service
- Reviews that mention actual installation experiences
- Complaints about delays, unresponsive teams, or sudden price hikes
Be cautious if a vendor has only 5-star reviews posted within a few days or if all reviews sound robotic. That’s usually a red flag.
Step 4: Make Sure They Have a Local Presence Near You
A vendor based in another state (or far away in your own) may not be able to provide:
- Fast maintenance or inspections
- Quick turnaround for net metering paperwork
- Replacement or repair support if something fails
Before finalizing:
- Ask if they have a local office or on-ground technicians in your city or district
- Get the contact of a local service head or support rep
If something goes wrong and you’re left dealing with a distant helpline, it’s going to be a headache.
Step 5: Don’t Ignore Solar Panel Warranties and Service Promises
Every serious solar installer should offer:
- 25-year panel performance warranty
- 5-10 years on inverter
- At least 5 years of installation workmanship warranty
Also ask:
- Do you offer optional AMC (Annual Maintenance Contracts)?
- Will someone visit if my inverter has an error?
- How do I raise a complaint or service request?
Get all this in writing or in your installation contract not just on WhatsApp.
Step 6: Watch for These Common Solar Scams in India
| Red Flag | What It Usually Means |
|---|---|
| Full advance payment asked before work | Vendor may disappear or delay installation |
| Unrealistic subsidy promise | Fake claims to hook you subsidy is fixed via govt |
| No GST invoice provided | Unregistered business or tax evasion |
| No mention of panel or inverter brand | Low-quality or used components may be used |
| Refuses to give customer references | Poor reputation or no real projects done |
| No physical address or office | Vendor may shut down and leave you stranded |
If even one of these applies, look elsewhere.
Step 7: Ask These Questions Before Signing a Solar Deal
- Are you listed as an approved vendor under MNRE or state nodal agency?
- Can you show me at least 2 recent installations in my area or size range?
- What panel and inverter brands will you be using?
- Who will handle the net metering paperwork with my DISCOM?
- What are the warranty periods and who do I contact for service?
- What does your quote include (and exclude)?
- What are your payment terms?
Don’t accept verbal answers. Ask for a written quotation with a full component breakdown.
