First Solar PV Modules

The Industry Benchmark for Utility-Scale PV Power Plants

Technologies & Capabilities /  Advanced PV Modules /  First Solar Advanced Thin Film Modules
First Solar’s advanced solar modules have set the industry benchmark for utility-scale PV. Our technology demonstrates a proven performance advantage over conventional crystalline silicon solar panels, delivering up to 9% more annual energy for the same nameplate watts. The Series 4™ Modules build on this advantage, leading the industry in quality and long-term durability.

Performance Advantage 

At temperatures above 25°C, First Solar modules produce more energy than competing solar modules due to a superior temperature coefficient.

This proven performance advantage provides stronger plant performance in high temperature climates, where more than 90% of a plant’s generation will occur when module temperatures are above 25°C—and First Solar modules have a proven performance advantage.

As a result of First Solar’s superior performance in high temperature and high humidity climates, First Solar power plants produce up to 9% more annual energy than competing power plants with the same nameplate capacity, providing bankable returns for our customers and partners.
