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.
Delivering Unmatched Value and Innovation
Taking a page from the automotive industry playbook, First Solar is the first PV module manufacturer to offer returnable and reuseable packaging for delivery of solar modules to project sites. This revolutionary change is expected to dramatically reduce the amount of landfill waste produced by solar module packaging, and the number of trees utilized for pallets and cardboard.
Once the returnable packaging is unloaded on site, it can be broken down for return shipment to the factory, where it will be reused for future module deliveries.
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 about four hours. Our latest flagship solar module incorporates 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 is produced with comprehensive supply chain management and zero tolerance for forced labor.
