Innovative Back Rail Mounting System

The Series 7 TR1 has galvanized steel back rails and next generation mounting methods will provide easier and quicker field operations resulting in a faster installation velocity, and lower BOS costs vs. Series 6.

The added strength of galvanized steel allows Series 7 TR1 modules to be mounted closer to the center of rotation on a tracker, improving the mechanical efficiency of the motors and dampeners. This can significantly reduce BOS costs by enabling longer tracker rows for more watts per motor, dampener and torque tube.

Larger Module Form Factor

First Solar’s proprietary manufacturing process and CadTel technology allow more form factor flexibility because it is not constrained by industry standard cell or wafer sizes. Along with the added strength and rigidity of galvanized steel back rails, the 1216mm x 2300mm module design optimizes form and function without fear of power loss from cell cracking or other performance-related issues prevalent in crystalline silicon modules.

More Lifetime Energy per Nameplate Watt

Series 7 modules will feature the industry’s best 0.3% warranty-backed annual degradation rate, and boasts a superior temperature coefficient, spectral and shading response – delivering more lifetime energy per installed watt compared to leading bifacial crystalline silicon PV panels.

Built in America for America

Series 7 TR1 is designed in California and Ohio and manufactured in Ohio specifically for the US utility-scale market. Utilizing uniquely American technology, First Solar transforms a sheet of glass into a fully functional PV module in just four-and-a-half hours. Our latest flagship solar module will incorporate the lessons learned and advantages of Series 6 and Series 6 Plus, building on more than two decades of R&D and product development experience to deliver a truly optimized system solution. Series 7 TR1 will be produced with comprehensive supply chain management and zero tolerance for forced labor

A Collaborative Process for Success

From day one, First Solar’s product engineering team has worked in deep collaboration with leading EPCs, structure and component providers to create a module that is part of an integrated system solution. By sharing designs and incorporating feedback from industry partners, First Solar has designed a module that is truly optimized for form, function, and cost.
