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.

Bifacial

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 the industry’s fastest energy payback time.



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, and credible third-party validation — all qualities that distinguish First Solar from Chinese manufacturers.



Made Responsibly

Comprehensive, transparent supply chain management with zero tolerance for forced labor.

Advanced Design

Series 6 Plus modules offer an advanced design that is optimized for every stage of your application, significantly reducing Balance of System (BOS), 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. 

Series 6 Plus V2 Featuring CuRe Technology

Series 6 Plus V2 is the first module to deploy First Solar’s groundbreaking CuRe technology — a revolutionary new semiconductor enhancement that delivers up to 8%* more lifetime energy per nameplate watt.

An industry-leading warranted annual degradation rate of -0.1% means that Series 6 Plus V2 modules are guaranteed to retain at least 95% of their original performance over a 30-year warranty period, compared to just ~84% for typical c-Si panels. Plus, they deliver improved performance in hot climates due to a temperature coefficient of -0.22%/˚C — another industry best.

Combined with all the proven features of the Series 6 Plus platform, Series 6 Plus V2 delivers a powerful blend of advanced technology, long‑term reliability, and superior energy yield — engineered to perform where it matters most. 

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.
