Innovative Back Rail Mounting System

Series 7 FT1 utilizes domestically sourced galvanized steel back rails and has been optimized for fixed-tilt applications.

Because there is no sunny-side frame to trap dirt and pooled water, this innovative design also promotes natural rain runoff, reduces soiling and improves energy performance. 

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.

Built in India for India

Series 7 FT1 is designed in the US and manufactured in India specifically for the Indian PV 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 FT1 is produced with comprehensive supply chain management with 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.
