What the company or idea is
First Solar is a U.S.-based solar panel manufacturer founded as Solar Cells, Inc. in 1990 by Harold McMaster, rebranded in 1999 after acquisition by True North Partners, and publicly traded since 2006.
How it actually makes money
First Solar makes money by manufacturing and selling cadmium telluride (CdTe) thin-film solar panels from U.S. factories in Ohio, Alabama, and Louisiana.
What works
Its CdTe thin-film process enables high-volume, low-cost module production in the U.S., achieving ~14 GW annual domestic nameplate capacity by March 2026.
What does not
It does not make silicon-based panels, does not rely on overseas supply chains for its core modules, and does not claim or demonstrate leadership in energy storage, software, or system integration.
What to take from it
Its CdTe thin-film technology is a deliberate divergence from mainstream silicon PV — a bet on lower material cost and domestic manufacturability, not efficiency or versatility.
Is it worth your time
Yes — it is one of the few vertically integrated solar manufacturers with domestic scale, but its business model depends entirely on policy-driven demand and commodity input costs outside its control.
