Unparalleled thin film technology. Superior performance. Lifetime energy advantage.
First Solar Series 6 Plus PV modules are built to perform and built to last. Combining superior performance with durability — and a proven record of successfully operating for the long haul through a full range of real-world conditions — sets Series 6 Plus modules apart from conventional crystalline silicon (c-Si) PV modules.

Up to 480Watts
Up to 19.0%Efficiency
30 YearLinear Performance Warranty
Up to -0.1%Warranted Annual Degradation Rate*
Optimized Design
Innovative Under-Mount Frame
Aluminum frames feature SpeedSlots for quicker installation and reduced hardware costs; nested horizontal shipping; and the cleaning and snow-shedding benefits of a frameless module.Dual Junction Box Design
Reduces wire management complexity and cost for module-to-module connections.Proprietary CdTe Semiconductor Technology
Superior degradation rate, shading response, spectral response, and temperature coefficient. Immune to Light-Induced Degradation (LID) and Light and Elevated Temperature-Induced Degradation (LeTID), which can cause power loss in c-Si solar panels.More Lifetime Energy per Nameplate Watt
The superior performance of First Solar’s CdTe semiconductor delivers up to 8%* more energy per nameplate watt over a 30-year warranty period.Industry’s Only Cell Cracking Warranty
First Solar modules are immune to and warranted against power loss from cell-cracking.Industry’s Most Eco-Efficient PV Solution
Among the lowest carbon and water footprints in the solar industry — outmatched only by First Solar’s Series 7 modules — plus an energy payback time that’s up to 2X faster than c-Si solar panels.Unrivaled Quality and Reliability
A vertically integrated manufacturing process with 100% QA/QC traceability produces tightly controlled, globally consistent, high-quality solar modules.Responsible Solar
Leadership in PV recycling, commitment to human rights, transparency, and credible third-party validation — all qualities that distinguish First Solar from Chinese manufacturers.Made Responsibly
Comprehensive supply chain management with zero tolerance for forced laborAdvanced Design
Series 6 Plus modules offer an advanced design that is optimized for every stage of your application, significantly reducing balance of system, shipping, and operating costs.
First Solar’s unique frame design allows for nested stacking to maximize shipping and handling efficiencies, reduce breakage, and minimize packaging waste.
Reliable Performance
Designed for longevity and manufactured with precision, Series 6 Plus modules are built to perform in real-world conditions. These modules are independently tested and certified for reliable performance that exceeds IEC standards, even in the most extreme environments.
Series 6 Plus Bifacial
First Solar sets high standards for reliable energy production, optimized design and environmental performance with the Series 6 Plus Bifacial — the world’s first bifacial thin film CdTe module.
Series 6 Plus Bifacial combines all the quality, reliability, and energy performance of Series 6 Plus, with added bifacial energy yield.
End-to-End Manufacturing
Series 6 Plus modules are manufactured with a vertically integrated, end-to-end process that results in fewer process steps and faster production times. A 100% traceable QA/QC program ensures a globally consistent, high-quality product.
