First Solar

First Solar is a leading American thin-film photovoltaic manufacturer headquartered in Tempe, Arizona. It designs, manufactures, and sells CadTel (cadmium telluride) solar modules primarily to large-scale utility developers and independent power producers globally, positioning itself as the only vertically integrated thin-film PV company of significant scale in the Western hemisphere.

First Solar's core product is its Series 6 and Series 7 CadTel thin-film modules. CadTel technology delivers superior performance in high-temperature and diffuse-light conditions versus conventional silicon, with lower energy and water consumption in manufacturing. Its proprietary deposition process enables high throughput, consistent quality, and a lower carbon footprint per watt than polysilicon alternatives.

First Solar operates large-scale gigawatt-level manufacturing across the United States, Malaysia, and Vietnam, with significant capacity expansion underway in India. Its total global nameplate capacity places it among the top module manufacturers outside China, with ambitions to exceed 20 GW annually as expansion programmes mature.

First Solar sells primarily to utility-scale solar developers, IPPs, and EPCs across North America, Europe, Australia, the Middle East, and increasingly India. Its India entry targets both domestic projects under government programmes and potential module exports. Long-term supply agreements with major developers anchor its revenue visibility globally.

First Solar's manufacturing relies on highly automated continuous deposition lines where CadTel is deposited onto glass substrates with minimal human intervention, enabling consistent quality at scale. Advanced machine vision, real-time process monitoring, and proprietary software optimise throughput and reduce defect rates. This automation-first model lowers labour dependency, supports rapid capacity ramp-ups, and drives down cost per watt systematically.

First Solar is the dominant non-Chinese utility-scale module manufacturer globally and the clear leader in thin-film PV. Its technology differentiation, US-origin manufacturing advantage under IRA, and long-term supply agreements with Tier-1 developers give it a defensible premium position versus low-cost Chinese silicon competitors.
