First Solar's strongest selling point right now is that it is a fully domestic, US-headquartered manufacturer. Yet the Downloads page offers about 45 documents, back to 2016 Series 2 datasheets, and not one that a developer, tax equity investor or lender can use to document domestic content or prohibited-foreign-entity status. The Series 7 page still footnotes its "100% Domestic Content" claim to Treasury's May 2023 guidance, although the safe harbor tables were replaced in 2024 and again in January 2025, and from January 1, 2026 projects must also show that at least 40% of their manufactured products are not from a prohibited foreign entity.

Why it works
Publish a "Compliance and Bankability" section on the Downloads page with, for each current module (Series 7 TR1, FT1, Series 6 Plus V2 and Bifacial): a domestic content statement mapped to the current safe harbor tables, a supplier and ownership statement for material assistance calculations, the manufacturing site, certifications, and the PVEL and bankability reports. Update the Series 7 footnote. Put the detailed certificates behind a short request form so the business development team sees which developers are asking.
Buyers have to prove compliance to claim credits; the supplier that hands them the paperwork first wins time and trust, and every request becomes a qualified lead.
