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