This is what a buyer checks before they shortlist electrical and electronics suppliers.
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.

First, what the product is
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.
Then the paperwork
Naming the documents 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 |

The shortlist moment
A buyer lines up a few suppliers and keeps the ones whose proof is easy to check. The rest get a closed tab, not an email.
The buyer asks: What does a client check before awarding a solar EPC contract?
A few suppliers get compared side by side:

Capacity, location, year and configuration of completed projects
A supplier with Performance ratio guarantee terms on the page
Guaranteed plant performance and the remedy if not achieved
A supplier with Safety record and certification on the page
Health and safety management and record

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.
