Documents requested in a solar pump tender
Below is the document list from one real solar irrigation tender: a World Bank funded programme in Madagascar for 1,700 pumping kits. Twelve items, each of which a bidder had to supply before the offer would be evaluated at all.
One tender is one buyer. Other procurements ask for different things. This is useful as a worked example of what a serious buyer looks for, not as a checklist that applies everywhere.
Twelve items
Not twelve pages. Several of them are document families, and the bill of materials alone can run to dozens of lines per kit.
Evidence, not claims
A signed curve, test reports behind certificates, a calculation rather than a statement. The pattern is consistent.
Four take real time
Authorisation, editable manuals, serial traceability and priced spares. Start those the day you decide to bid.
The twelve, and what each one means
| Document | What the tender asked for |
|---|---|
| Manufacturer authorisation | A letter from the factory naming this project and this buyer, not a generic distributor certificate. |
| Authenticity and conformity declaration | Goods are new, in current production, not refurbished, and the datasheets match the model numbers offered. |
| Data sheets | Official datasheet for every pump, controller and module, with country of origin stated. |
| Hydraulic evidence | A signed flow-versus-TDH curve with the duty point highlighted on it. |
| Electrical evidence | Controller input limits, module electrical data, and a full sizing calculation showing the array stays inside those limits at the design temperature extremes. |
| Module certification | IEC 61215 and IEC 61730 certificates with the supporting test reports. |
| Kit nomenclature | A complete bill of materials per kit, with manufacturer, model and part number on every line. |
| Drawings | Mounting structure drawings, structural drawings, anchoring and foundation details. |
| Manuals | Installation, operation, troubleshooting and maintenance manuals, supplied as editable source files so the buyer can translate them locally. |
| Warranty and spare parts | Warranty terms plus a recommended spare parts list with prices held for a stated period. |
| Traceability | A serial number, barcode or QR system covering pumps, controllers and modules, with a register template. |
| Quality documents | Factory quality certificates, factory address, production lead time and the inspection procedure. |

The pattern underneath the list
Read the twelve together and the same instruction repeats: prove it, do not assert it. Three examples make the point.
| Not "the pump meets the duty" | A signed curve with the duty point highlighted on it. |
| Not "the array matches the controller" | A calculation showing the array stays inside the controller limits at both design temperature extremes. |
| Not "the modules are certified" | The IEC 61215 and IEC 61730 certificates together with the test reports behind them. |
That is the useful takeaway even if you never bid on this particular programme. A buyer who asks this way is not being difficult; they are protecting themselves from an offer that looks compliant on a specification sheet and is not.
Four that take longer than you expect
Eight of the twelve are a matter of collecting paperwork the factory already has. Four need someone to go and ask for something that is not routine.
Manufacturer authorisation naming the project
Factories issue these, but not automatically and not always in the form a tender wants. Worth starting the moment you decide to bid, not the week before submission.
Editable manuals for local translation
Most factories hand over a locked PDF. Getting the source file is a commercial conversation, and it is easier before the order than after.
Serial number traceability with a register template
Individually recording serials across a container of kits is real work at the packing stage. It has to be agreed with the factory up front or it does not happen.
A spare parts list with prices held
Straightforward to produce, but the price validity period is a commercial commitment, so it needs a decision rather than a document.
On manufacturer authorisation specifically
This is the item that most often stops a trading partner, and it deserves its own answer rather than a line in a table. What a sourcing partner can and cannot provide sets out plainly when a factory will issue one, how the letter should be addressed, and how a buyer can verify it is real.
How we work a document pack
We coordinate the pack with audited partner factories and hand it over as one set rather than as attachments arriving over three weeks. What we can commit to on any given bid depends on what the factory will issue for that project, so we say which items are confirmed and which are still open rather than implying everything is in hand.
If you are preparing a bid and want to know where the gaps would be before you commit time to it, send us the document list from the tender and we will go through it item by item.
Send us the tender document list
We will go through it line by line and tell you which items are routine, which need the factory to agree something, and where a realistic timeline lands.
Tender document FAQ
What documents does a solar pump tender ask a supplier for?
In the tender described on this page, twelve: manufacturer authorisation, an authenticity and conformity declaration, datasheets, a signed hydraulic curve, electrical sizing evidence, module certification to IEC 61215 and IEC 61730, a full kit bill of materials, drawings, editable manuals, warranty and spare parts terms, a serial number traceability system, and factory quality documents. Other tenders will differ; this is one real list rather than an industry standard.
What is a hydraulic evidence document?
A flow-versus-total-dynamic-head curve for the exact pump model, signed, with the project duty point highlighted on it. It is the document that proves the pump does what the specification asks at the point that matters, rather than at its catalogue maximum.
Why do tenders ask for editable manuals rather than PDFs?
Usually so the buyer can translate them into the local working language, which in francophone Africa means French. A locked PDF cannot be translated without retyping it. If a tender asks for source files, raise it with the factory early: it is a commercial conversation, not a technical one.
Can a trading company supply these documents?
Most of them, yes, because they originate with the factory and are passed through. The two that need real work are manufacturer authorisation naming the project and buyer, and anything requiring the factory to change its normal practice, such as editable manuals or per-unit serial registration. Those are worth starting early.
What is a kit nomenclature in a tender?
A complete bill of materials for each kit type, with manufacturer, model and part number on every line, down to clamps and connectors. It lets the evaluator check that what is offered is actually complete, and it is what the buyer will hold you to on delivery.
Which certificates are asked for on the PV modules?
IEC 61215 and IEC 61730, with the supporting test reports rather than just the certificate front page. Both are standard for crystalline modules from established factories, so this one is normally a matter of collecting paperwork rather than a risk.
