Series 7 TR1 | 525–550 W Thin Film Solar Module | First Solar

The Series 7 TR1 is a high-output, utility-grade thin film solar module engineered and manufactured in the United States. Delivering between 525 and 550 Watts, this module is optimized for large-scale solar projects requiring high energy yield, reliability, and long-term performance in diverse environmental conditions.

Featuring advanced thin film technology, the Series 7 TR1 performs exceptionally well in high-temperature, low-light, and partially shaded environments. It offers a lower temperature coefficient compared to crystalline modules, ensuring better output under real-world heat and irradiance conditions.

The frameless dual-glass design offers durability, self-cleaning surfaces, and resistance to potential-induced degradation (PID) and light-induced degradation (LID). With a robust structure and high mechanical load tolerance, the Series 7 TR1 is built for long-term field operation with minimal maintenance.

Made in the U.S., this module meets requirements for domestic content incentives, including IRA compliance and Buy American provisions, making it an excellent choice for public and utility-scale installations aiming for local sourcing benefits.
