7 Red Flags Before Hiring Solar EPC Gujarat

A wrong solar EPC company costs you more than money.

Sp Before hiring a rooftop solar EPC company in Gujarat, check for 7 critical red flags:

1. No MNRE empanelment

2. Skipping a site visit before quoting

3. Vague quotations with missing component details

4. Inability to explain the DISCOM net metering process

5. No written after-sales service policy,

6. No verifiable project portfolio with client references

7. Pressure to pay the full amount upfront.

A wrong solar EPC company delays your DISCOM approval, risks your PM Surya Ghar subsidy claim, and leaves you with an underperforming system for 25 years.

Verify each of these checkpoints before you sign any aggreement so to know every red flags in indetail explore this whole guide

TL;DR

• No MNRE empanelment or license? Walk away immediately.

• Vague quotations with missing component details are a financial trap.

• Zero after-sales service policy means you are on your own post-installation.

• Companies that skip site visits give you a system designed for someone else's roof.

• If they cannot explain your

  DISCOM net metering process

  , they cannot execute it either.

Why This Decision Matters More Than You Think

Choosing a solar EPC company in Gujarat is a 25-year commitment, not a one-time purchase.

A 5kW rooftop system costs anywhere between Rs. 2.5 to 4 lakh. A poor vendor can deliver low-quality panels, skip the DISCOM paperwork, and disappear after installation.

You are left without net metering benefits and a system that produces 30-40% less power than promised.

Gujarat's solar market is growing fast. That growth also attracts unqualified installers who cannot deliver on their promises. This guide gives you a practical checklist to filter them out before you commit.

Red Flag 1: No MNRE Empanelment or Verifiable License

An unlicensed solar installer cannot legally claim government subsidies on your behalf.

The Ministry of New and Renewable Energy (MNRE) maintains a list of empanelled vendors who meet quality and safety standards.

Hiring outside this list means your PM Surya Ghar subsidy application can get rejected. It also means the installer may not follow CEA (Central Electricity Authority) wiring guidelines.

Ask every shortlisted company directly: "Are you MNRE empanelled?"

• Request their vendor registration number.

• Cross-check it on the MNRE portal.

• Confirm they have a valid electrical contractor license for Gujarat.

If they dodge this question or give a vague answer, treat it as a hard stop.

Red Flag 2: No Physical Site Visit Before Giving a Quote

A company that quotes without visiting your roof is guessing, not engineering.

Every roof in Surat, Ahmedabad, or Vadodara has different conditions.

Shadow angles from water tanks, roof load capacity, terrace orientation, and the type of existing electrical setup all affect your system design. A remote quote ignores all of these.

What a proper site visit includes:

• Roof condition and structural load check

• Shadow analysis at different times of day

• Existing meter and electrical panel inspection

• Measurement of available panel area

Earthwave Solar's rooftop solar process starts with a no-pressure consultation followed by a detailed site visit.

Their engineers assess roof condition, sun exposure, and electrical setup before designing a single system.

Red Flag 3: Vague Quotation with Missing Component Details

A quotation without complete component specifications is a blank cheque in disguise.

Unscrupulous installers quote a low price using Tier-3 panels and unbranded inverters. Once you pay, they substitute cheaper alternatives and you have no paper trail to challenge them.

A proper quotation must include:

• Panel brand, model, wattage, and efficiency rating

• Inverter brand, capacity, and warranty period

• Structure material (GI or aluminium) with thickness

• AC and DC cable specifications

• Earthing, lightning protection, and protection device details

• Net metering application and DISCOM coordination fees

See the full Solar EPC Company Checklist India to know exactly what a contract should cover.

If any of these are missing or listed as "as per site," ask for full clarification in writing before proceeding.

Red Flag 4: No Clarity on DISCOM Net Metering Process

If your installer cannot explain the DISCOM net metering approval process step by step, they likely cannot execute it either.

Net metering is what converts your rooftop system from a cost centre to a savings machine. In Gujarat, you need DGVCL, GETCO, PGVCL, or UGVCL approval depending on your location.

This involves technical sanction, bidirectional meter installation, and a formal interconnection agreement.

Many small installers skip this process or handle it incorrectly. The result: your system generates power but you never get credit for units exported to the grid.

Ask your shortlisted company:

• Which DISCOM handles my area and connection type?

• How long does your average net metering approval take?

• Do you handle all documentation or do I manage it myself?

A company with real execution experience gives you a timeline and process map, not vague assurances.

Red Flag 5: Zero or Vague After-Sales Service Policy

After-sales service is where most solar companies in Gujarat fail their customers.

Your solar system will run for 25 years. Inverters can trip. String fuses blow. Monitoring dashboards stop updating.

What happens when you call your installer 18 months after installation?

Watch out for these warning signs:

• No written AMC (Annual Maintenance Contract) offered

• Service response time not mentioned in the contract

• No dedicated service team or local presence

• Only WhatsApp support with no escalation process

Ask for their service SLA (Service Level Agreement) in writing. A credible EPC company commits to specific response times and has a local technical team in your city.

Earthwave Solar provides real-time monitoring through smart dashboards and offers ongoing maintenance support post-installation.

Their Wave Inverters come with a 10-year warranty, and their technical engineers conduct a thorough handover before they leave your site.

Red Flag 6: No Portfolio of Completed Projects with Verifiable References

A solar EPC company without a verifiable project portfolio is asking you to trust a promise, not a track record.

Any company can show you a brochure. Ask for actual completed project details: client name, location, system size, and installation date.

Then call the client directly and ask two questions.

• Did the system perform as promised in the first year?

• How did the company respond when something went wrong?

What a strong portfolio looks like:

• Projects across different scales: residential, commercial, and industrial

• Long-term clients, not just one-off installations

• Named clients willing to provide references

Earthwave Solar has executed projects including a 30kW residential system at River Penta Sky, 170kW industrial installation at Pari Textile Diamond Nagar, and an 80MW ground mount project for Mahindra Sustain. View their complete project portfolio here.

Their clients include Goldi Solar, Torrent Power, and DGVCL, names that do not associate with underperforming vendors.

Since 2018, the company has built over seven years of EPC execution experience across Gujarat and Madhya Pradesh.

Red Flag 7: Pressure to Sign Quickly or Pay Full Amount Upfront

Any installer who pressures you to decide within 24 hours or demands 100% upfront payment is protecting themselves, not serving you.

Legitimate EPC companies structure payments in milestones tied to project stages: advance on signing, payment on material delivery, and final payment on commissioning.

Pressure tactics exist to prevent you from comparing quotes or checking credentials properly.

Watch for these specific behaviours:

• "This price is only valid today" on a large project quote

• Request for full payment before site visit or documentation

• Reluctance to provide a written contract with project timelines

• Promises of subsidy amounts before any documentation is reviewed
