Solar supplier due diligence for US buyers
The expensive mistakes surface after the deposit clears.

On VyaparCred the first layer is done before anyone quotes: certification, manufacturing capability and trade history. How far you go after that, from document review to an independent factory audit, depends on the size of the order.

Three due diligence questions worth settling early
What solar supplier due diligence looks like when the first layer is finished before anyone bids.
You
“Is a checked supplier the same as an audited one?”
VyaparCred
No. The check before quoting covers certification, manufacturing capability and trade history. A factory audit goes further: an auditor on the floor, reviewing the quality system and the lines that would build your order.
For large or first orders, buyers commission that from an independent auditor. The earlier checks narrow the field, so you only pay to audit a supplier worth auditing.
How to verify a supplier's credibilityYou
“What's solar conformity assessment, and should I care?”
VyaparCred
It's the process that shows a product meets a standard: testing by a lab, certification by a certification body, sometimes an inspection of the factory. The certificates and test reports a supplier hands you are its output.
What you care about is that those documents cover the exact model, and the factory, in your order.
What documents prove solar panel complianceYou
“When should the inspection happen?”
VyaparCred
Before the balance is paid, while you still have leverage. A pre-shipment inspection checks finished goods against your spec, and on VyaparCred, documents, inspection and milestones are tracked on the order.
If the supplier is overseas, a letter of credit can list the inspection certificate among the documents required for payment.

Match the depth to the order
How deep should solar supplier due diligence go?
A small repeat order and a first order worth millions don't deserve the same process.
Most orders
Document review
Test reports, quality certification and traceability records for your model.
Large or first orders
Factory audit
An independent auditor on site, reviewing lines, materials and the quality system.
Before the balance
Pre-shipment inspection
Finished goods sampled and checked against your spec before they ship.

- Inspection before the balance
Financing
Make payment wait for the paperwork
Two ways to tie the money to what your solar supplier due diligence finds.
The supplier is overseas
Trade finance and LCs
A letter of credit pays only against the documents it lists, which can include an inspection certificate.

FAQ
Solar supplier due diligence questions, answered
What does solar supplier due diligence involve?
Confirming a supplier's certification, manufacturing capability and trade history, reviewing test reports, quality systems and traceability for your order, and for large orders, adding an independent audit and a pre-shipment inspection.
What does a solar supplier audit cover?
A solar manufacturer audit puts an auditor in the factory to review production lines, incoming material controls, the quality management system and the records behind the product you're buying.
Is a PV supplier audit worth it for every order?
Usually not. It pays off on first orders with a new supplier, on large orders, and on orders your lender or client scrutinizes. Repeat orders with a known supplier often need only documents and inspection.
What is solar conformity assessment?
The testing, certification and inspection that show a product meets a standard. The certificates and test reports a supplier provides are its results.
Can I hold payment until the inspection is done?
Yes, if the order is structured that way. Pay the balance after a pre-shipment inspection, or use a letter of credit that lists the inspection certificate among its required documents.
