How to Choose a Solar EPC Company in Gujarat: 10-Point Checklist
Quick answer
Choose a solar EPC company in Gujarat by verifying ten points, starting with GEDA empanelment, DISCOM registration, and completed projects. Then check equipment brands, contract scope, payment milestones, warranties, O&M support, references, and net metering handling.
Ask for documents, not promises. Compare quotes only after every bidder prices the same scope.
Solar EPC company: a firm that delivers Engineering, Procurement, and Construction of a solar plant under one contract. It designs the system, buys the equipment, installs it, and commissions the plant.
What Should You Look for in a Solar EPC Company?
Look for ten verifiable items, from registrations and comparable projects to contract terms and after-sales support. First, use the table below as a screening sheet, and score every bidder against it.
Gujarat held 29.30 GW of installed solar capacity in March 2026, according to MNRE Renewable Energy Statistics 2025-26 (September 2026). Buyers therefore face many contractors, whether they need industrial rooftop solar or a ground-mounted plant.
| Point | Checkpoint | What to verify | Why it matters |
|---|---|---|---|
| 1 | GEDA empanelment | Registration number on GEDA’s vendor list | Signals vetting by the state nodal agency |
| 2 | DISCOM registration | Registration with your electricity distribution company | Rooftop programme vendors need it |
| 3 | Comparable projects | Completed plants of similar size and type | Shows the team has solved your problem before |
| 4 | Client references | Past customers you can phone | Reveals real delivery and support behaviour |
| 5 | Equipment | Named panel, inverter, and structure brands | Determines output, durability, and warranty cover |
| 6 | Engineering | Yield simulation, single-line diagram, structural check | Prevents undersizing and roof load problems |
| 7 | Contract | Itemised scope, timeline, and payment milestones | Protects you from hidden exclusions |
| 8 | Warranty | Workmanship and performance terms in writing | Defines who pays when output falls short |
| 9 | After-sales | O&M plan, monitoring, and response time | Keeps generation steady after handover |
| 10 | Approvals | Net metering and grid-connection handling | Decides when the plant starts saving money |
How Do You Verify a Solar EPC Company’s Credentials?
Verify credentials by requesting documents and checking each one with its issuing body. First, get the GEDA empanelment number, then ask for DISCOM registration and an electrical contractor licence.
MNRE’s programme requires vendors to register with their DISCOM and maintain plants for five years, according to MNRE’s rooftop memorandum (June 2022). However, any bidder, including Raycal Power, should show similar paperwork on industrial projects.
- GEDA empanelment certificate
- DISCOM registration proof
- Electrical contractor licence
- GST registration
- Company incorporation certificate
- Written safety procedures for site work
- Proof of insurance for site workers
⚠️ Red Flag
A contractor who cannot produce a verifiable registration number is a warning sign. The same goes for anyone who pushes you to sign the same day. Walk away and shortlist the next bidder.
How Important Is the EPC Company’s Project Experience?
Project experience matters most when the contractor has already built plants like yours. So ask for commissioned capacity, project type, and location for every reference.
A rooftop specialist may lack grid-synchronisation experience, so match the record to your project, such as ground-mounted solar EPC work. Raycal Power, for instance, lists 18 commissioned ground-mounted plants across Amreli, Bhavnagar, and Banaskantha.
Also ask each reference for these details:
- Commissioning date and installed capacity
- Generation record since commissioning
- Name of the O&M provider
- Any performance issues since handover
- Frequency of maintenance visits
“Visit a live plant and request its commissioning report. Photos prove a plant exists; generation data proves it performs.”

What Should a Solar EPC Contract Include?
A solar EPC contract should state scope, equipment, timeline, payment milestones, warranties, and maintenance terms in writing.
- Scope: design, supply, installation, approvals, and commissioning
- Equipment: named panel, inverter, and structure makes and models
- Timeline: start, commissioning, and grid-connection dates
- Payment: instalments tied to inspected milestones
- Performance: guaranteed generation or plant availability terms
- Warranty: workmanship and equipment cover, with the claim procedure
- Maintenance: O&M term, response time, and exclusions
- Handover: commissioning report, drawings, and manuals
Also insist on the same itemised scope from every bidder. Verbal promises and vague line items leave you without recourse.
💰 Budget Insight
A low headline price often hides excluded items such as approvals, structures, or monitoring. One bidder may quote a lower rate per watt simply because it leaves items out. So ask each bidder to price the same list before you compare totals.
How Do You Compare Solar EPC Quotes?
Compare solar EPC quotes line by line, using the same scope, equipment, and warranty terms for every bidder.
- Normalise scope by listing every included and excluded item.
- Match equipment by capacity, brand, and warranty period.
- Convert each total to a cost per watt-peak.
- Score timelines, payment milestones, and after-sales terms.
- Request a revised written quote after the site survey.
| Quote element | Strong quote | Weak quote |
|---|---|---|
| Scope | Itemised, with exclusions listed | One lump-sum line |
| Equipment | Named makes and models | “Tier-1 or equivalent” |
| Payment | Milestones linked to inspections | Large advance, no milestones |
| Timeline | Dated start and commissioning | “Soon after payment” |
| Warranty | Terms and claim steps in writing | Verbal assurance |
| Approvals | Named owner for net metering filing | Left to the customer |

How Do You Evaluate Solar EPC After-Sales Service?
Evaluate after-sales service by asking for a written O&M plan, a monitoring method, and a committed response time. A solar plant runs for many years, so support must outlast the installation team.
- Remote monitoring access to your plant data
- Scheduled preventive maintenance visits
- A named contact for fault reports
- A written response time for breakdowns
- An annual report comparing actual and expected generation
- Spare inverter availability for quick replacement
For example, Raycal Power pairs SCADA-based remote monitoring with defined response SLAs from its field team. Ask every bidder for equivalent commitments in writing.
🎯 Insider Recommendation
We tell every buyer to ask one question before signing: who answers when a fault alarm triggers? A named contact with a written response time beats any brochure promise. Then test it by calling that number yourself.

Frequently Asked Questions
What questions should I ask a solar EPC company?
Ask for GEDA and DISCOM registration numbers, three project references, equipment brands, warranty text, and O&M response time. Then request every answer in writing, because written answers become contract terms. Finally, ask who will manage your project from survey to commissioning.
What are the red flags of a weak solar EPC company?
Red flags include no verifiable registration, vague scope, unnamed equipment, verbal-only promises, and pressure to sign quickly. Also watch for references the company will not let you contact. Any one of these justifies asking a second bidder for a proposal.
Is the cheapest solar EPC quote the best choice?
No. The cheapest quote often omits items that other bidders include, such as approvals or monitoring. So compare price only after scope, equipment, and warranty terms match. A fair comparison uses one itemised scope for every bidder.
Should the EPC company handle net metering and approvals?
Yes. A good contract names who files the net metering application and grid-connection paperwork. Also confirm this in the scope, because approval delays hold up commissioning. Ask for the expected approval steps in writing.
Should I pick a local Gujarat EPC company or a national one?
Pick the company with verified registrations and comparable projects in your DISCOM area. Local presence helps response times, but documented delivery matters more than headquarters. Also confirm that a service team sits within reach of your site.
Do I need a site visit before signing an EPC contract?
Yes. A survey checks shading, roof strength or land condition, and grid access. So insist that the proposal reflects the survey findings, not a generic design. Then compare designs, because different assumptions change the quoted output.
Next Steps for Your Shortlist
Shortlist three GEDA-empanelled contractors, request the documents listed above, and compare quotes on identical scope. Then book site visits with the two strongest bidders and compare their designs side by side.
Overall, as Gujarat’s solar base keeps growing, contractors with documented delivery will stand out.
