Procurement and Regulatory Context in United States

When shortlisting a supplier in United States, ask how they handle grid-connection paperwork, who carries responsibility for permitting, and whether quoted prices include VAT and post-commissioning service.

Verification and Trust Signals

Listings in United States include both verified and unverified profiles. Verification is an opt-in programme: a company completes PVFirms's identity and credentials check before the badge is shown. Use the Verified filter on this page to narrow results to companies that have completed it, and treat an unverified listing as a starting point for your own due diligence rather than an endorsement.

How to Choose a EPC & Project Developer in United States

  • Check certifications recognised in United States, not only international ones — national schemes are what grid operators and insurers actually ask for.
  • Compare at least three quotes. Scope differences, not headline price, explain most of the spread.
  • Confirm hands-on experience with grid-connection procedures in United States and with the relevant distribution network operator.
  • Ask for two or three reference projects delivered in United States in the last three years, and contact them.
  • Verify insurance cover and who honours the warranty if the supplier or manufacturer exits the market.
  • Establish which work is done in-house and which is subcontracted, and who your single point of accountability is.
