This is what a buyer checks before they shortlist a electrical and electronics supplier.
What does a client check before awarding a solar EPC contract?
They check the capacity you have actually delivered and commissioned, the performance guarantee you will stand behind, and your financial capacity to carry the contract. EPC selection is a counterparty decision more than a technical one.
A client is awarding a contract where the contractor's failure mid-project would be worse than a slightly higher price.

What a buyer needs to identify the product
These are the fields a buyer scans before deciding whether you are worth contacting. Missing one of them usually ends the visit without an email.
- 1
Capacity delivered and commissioned
The primary evidence of capability.
- 2
Project types handled
Rooftop, ground mount, floating and hybrid differ substantially.
- 3
Scope offered
Full EPC, balance of plant or installation only.
- 4
Performance guarantee offered
The commercial substance of the contract.
- 5
In-house versus subcontracted work
Determines control and risk.
- 6
Operations and maintenance capability
Whether the relationship continues after handover.
- 7
Geographic coverage
Where you can actually mobilise.
The documents buyers ask for
Not all of them belong on a public page. Naming the ones you can issue is what separates a supplier who can be audited from one who cannot.
| Document | What it proves | Where it belongs |
|---|---|---|
| Commissioned project listAsked at: qualification — the primary evidence | Capacity, location, year and configuration of completed projects | Publish it |
| Performance ratio guarantee termsAsked at: contract negotiation | Guaranteed plant performance and the remedy if not achieved | Publish it |
| Commissioning test reportsAsked at: handover | Measured plant performance at handover | Per shipment |
| Safety record and certificationAsked at: prequalification | Health and safety management and record | Publish it |
| Financial statements or bonding capacityAsked at: prequalification | That the contractor can carry the contract | Name it, share on request |
| Design documentation and yield assessmentAsked at: technical review | The basis of the projected generation | Name it, share on request |
| Warranty and defects liability termsAsked at: contract | What is covered after handover and for how long | Publish it |
Where renewable energy epc sites lose the enquiry
Each of these is common, cheap to fix, and costs an enquiry that never arrives — so nobody ever reports it.
Project list without capacity, date and location
"Over one hundred projects" is not evidence. Clients assess whether you have delivered projects like theirs, which requires the specifics.
Performance guarantee not offered or not explained
It is the commercial substance of an EPC contract. A contractor unwilling to guarantee performance is competing only on price.
Subcontracting arrangements undisclosed
Clients need to know who actually performs the work, because that is where quality and schedule risk sits.
What the enquiry form should ask
A form that collects these can be answered properly the first time. A form that collects a name and a message cannot.
Enquiry form — renewable energy epc
Enough to reply usefully, short enough that a buyer finishes it.
- Project location and capacity
- The basis of any proposal.
- Site type and land or roof details
- Determines the design approach.
- Scope required
- EPC, supply only or with operations and maintenance.
- Grid connection status
- Frequently the critical path item.
- Financing arrangement
- Lender requirements change the contract.
- Target commissioning date
- Drives the whole programme.
Questions suppliers ask
What evidence most reduces a client's risk?
A specific project list with capacity, location, year and configuration, and permission to speak to those clients. EPC selection is a judgement about whether you will finish, and comparable completed projects address that far better than any capability statement.
Should performance guarantees be discussed publicly?
Explaining what you guarantee and how it is measured is a strong position, because many contractors avoid the subject. Clients are trying to understand whether generation shortfall is their problem or yours, and a clear answer is a commercial advantage.
How should operations and maintenance be presented?
As a distinct offer with defined scope, response times and reporting. Clients increasingly prefer continuity between construction and operation, and a contractor who can carry both reduces the interface risk that causes disputes over underperformance.
Documents and standards named here are the ones buyers in this industry commonly ask for; requirements vary by market, customer and contract, so treat this as a starting checklist rather than a compliance list. Clearer pages can help discovery and evaluation. They do not guarantee rankings, AI citations, enquiries or revenue.
