The FS-7475A-TR1 is a cutting-edge thin-film solar module that leverages advanced Cadmium Telluride (CdTe) semiconductor technology to deliver superior real-world energy performance. Unlike conventional crystalline silicon panels, First Solar's proprietary thin film technology generates up to 8% more energy per nameplate watt thanks to exceptional temperature performance, superior spectral response, and enhanced shading behavior.
The innovative frameless glass-on-glass construction is a standout feature of this design. This durable configuration not only provides a sleek, all-black aesthetic but also improves soiling resistance and snow shedding capabilities. The absence of a traditional aluminum frame eliminates potential failure points while enhancing the panel's modern appearance. Novel design solutions also include a dual junction box system that significantly reduces wire management complexity and installation costs. The optimized back rail mount design with two galvanized steel rails further enhances installation velocity, making it ideal for large-scale ground mount projects.
First Solar stands behind this module with industry-leading warranty coverage: 12 years of product protection and an impressive 30-year linear performance warranty. The company guarantees 98% of rated power at warranty start, with minimal degradation of just 0.6% annually after the first year, ensuring at least 80.6% of original performance after 30 years of operation.

More Power and Real-World Energy Production
An already impressive efficiency of 17.0% is enhanced by anti-reflective coated glass and First Solar's advanced thin film technology. The module is completely immune to Light Induced Degradation (LID) and Light and Elevated Temperature Induced Degradation (LeTID) – power losses that plague crystalline silicon panels. Under standard test conditions, the FS-7475A-TR1 delivers 475 W of reliable power output.
Superior Performance at High Temperatures
Exceptional performance as temperature rises is the hallmark of an excellent temperature coefficient. This panel's efficiency will drop by just -0.32% for every 1.8°F increase over 77°F – significantly outperforming conventional crystalline silicon modules in hot climates and ensuring maximum energy production year-round.
Quality and Reliability
The FS-7475A-TR1 undergoes rigorous quality checks throughout First Solar's vertically integrated, end-to-end manufacturing process. Produced entirely in the USA with highly automated facilities, each module is tested and certified to IEC standards and beyond. First Solar's commitment to quality, safety, and reliability ensures globally consistent performance you can depend on.
Exceptional Reliability and Degradation Resistance
First Solar guarantees minimal deterioration over the next 30 years. Performance will decline by no more than 2% during the first year and then by no more than 0.6% annually thereafter. After 30 years of operation, your modules will retain at least 80.6% of their original performance – among the best degradation rates in the industry. This 475 W First Solar panel also comes with a substantial 12-year product warranty, protecting against manufacturing defects and even cell cracking.
A Panel Built to Handle Extreme Conditions
The robust glass-on-glass construction with heat-strengthened front and back glass, combined with advanced laminate encapsulation and edge sealing, makes this module exceptionally weather-resistant. The module can withstand loads up to 2400 Pa (both positive and negative), handling hail, high winds, and heavy snow with ease. Operating temperature range spans from -40°C to 85°C.
The panel is also rigorously tested for extended durability, including salt mist corrosion (IEC 61701), dust and sand resistance (IEC 60068-2-68), and ammonia corrosion (IEC 62716) – ensuring reliable performance in harsh agricultural, coastal, and desert environments.
Outstanding All-Black Frameless Design
The panel features a premium all-black design that delivers a sleek, modern appearance perfect for ground mount installations. The frameless glass-on-glass construction creates clean lines and an uninterrupted surface. First Solar's thin film technology naturally produces uniform black cells, while the absence of visible busbars and metal frames ensures a smooth, sophisticated aesthetic from every angle.
