Message from the CEO Rapid deployment of power generation capacity is necessary to drive not just the Age of Electrification — where everything that can be electrified may be — but a potentially transformational era of artificial intelligence. In a world where unanimity is rare, there is no disputing that unleashing economic growth and prosperity depends on reliable, competitive, rapidly deployable power generation. Utility-scale solar is key to this dynamic. The speed, ease, and competitive cost of deploying significant amounts of utility-scale solar capacity make it an unparalleled power-generation...

Given the backdrop of unprecedented demand and utility-scale solar’s proven capabilities, this is a time of abundant opportunity for our industry. And yet, even as utility-scale solar meets the moment, it faces unprecedented challenges, including declining public trust and acceptance. There is a real and increasingly urgent need for the industry as a whole to bolster key stakeholder support for utility-scale solar and safeguard its social license to operate. This requires the solar industry to respond with facts and data, and highlight its compelling narratives, while consistently doing the right...

In making our commitment to corporate responsibility intrinsic to our business, we further differentiate ourselves from the competition while building value. Our uniquely American solar technologies continue to set us apart from companies that rely on crystalline silicon technology, which is dominated by China. Our vertically integrated manufacturing operations create value at every step by virtue of a differentiated process that transforms raw materials into a complete, ready-to-ship solar panel in a matter of hours, under one roof. Our vertical integration also drives resource efficiency, enabling...

Finally, no conversation about corporate responsibility is complete without addressing human rights. At First Solar, we have long believed in doing right by our associates, customers, and the communities in which we live and work. Our commitment to doing the right thing extends to our efforts to ensure that our operations are free from human rights abuses, including forced labor. While major solar trade associations in the US and Europe remain satisfied with efforts to bifurcate Chinese supply chains rather than decisively confront the issue, we continue to advocate for a single global standard...

About First Solar Uniquely American Solar Technologies In a market dominated by Chinese manufacturers, First Solar stands apart with technologies created and manufactured in America with American components from American supply chains. Developed at R&D labs in California and Ohio, our thin film technologies represent the next generation of solar power generation, providing a competitive, high-performance, and responsibly produced alternative to conventional crystalline silicon PV solar modules. Our thin film solar modules are produced using a fully integrated, continuous process that does not...

About First Solar First Solar’s advanced thin film modules are manufactured in a highthroughput, automated environment that integrates all manufacturing steps into a continuous-flow operation, using less energy, water, and semiconductor material than conventional crystalline silicon PV manufacturing. In about four hours, our vertically integrated manufacturing process transforms a sheet of glass into a complete PV module — flash-tested, packaged, and ready for shipment. This resource-efficient process enables First Solar modules to deliver a greater energy return on energy invested than more...

About First Solar From 2002 through 2024, First Solar has sold more than 75 GW of PV solar modules. solar modules have the equivalent nameplate capacity* of: - or 125 new natural gas power blocks Olympic-sized pools of water per year** metric tons of CO2eq per year** criteria pollutants, heavy metals, and radioactive species*** Every year, 75 GW of First Solar products displace more than 47 million metric tons of CO2eq, which is more than eight times the amount of greenhouse gas emissions we emit through our global operations and supply chain. Assuming worldwide average irradiance and grid electricity...
