An average over a catalogue describes the range a manufacturer publishes, not the module you would buy. A brand with two flagship panels and eighty older ones averages worse than one that has retired its back catalogue.

Written summary

First Solar is a United States-based manufacturer headquartered in Tempe, Arizona, with manufacturing plants in Ohio, Alabama, Louisiana, India, Malaysia, and Vietnam. Founded in 1999 and spun out of the Walsin Lihwa group's thin-film research program, First Solar has grown into one of the most institutionally recognized solar module producers globally. The company consistently appears on BloombergNEF Tier 1 bankability lists and commands more than 30% of the U.S. utility-scale PV market. Its annual nameplate production capacity reached approximately 13 GW in 2025 and is projected to exceed 25 GW globally by 2026, according to SEC filings. A.B. Energy, by contrast, is an Italian company that search results characterize as a distributor and energy-efficiency solutions provider rather than a vertically integrated module manufacturer. No evidence of Tier 1 or BloombergNEF bankability recognition could be found for the brand, and its production footprint appears to be regional and modest at best. First Solar clearly holds the stronger institutional footprint by a wide margin.

On the product side, First Solar is built around a single, well-defined technology: cadmium telluride thin-film modules, most notably the Series 7 line, which is optimized for large utility-scale ground-mount deployments. The technology delivers module efficiency in the 18-20% range and performs relatively well under high-temperature and diffuse-light conditions. First Solar offers a 30-year performance warranty - unusually long for the industry - and NREL data cited by independent reviewers shows panels retaining roughly 88% efficiency after 25 years of outdoor testing. A.B. Energy's product offering in solar panels could not be characterized from available sources; the company appears to distribute or resell equipment from third-party brands rather than manufacturing its own modules.

For any buyer evaluating these two brands in 2025 - whether for utility-scale, commercial, or residential projects - First Solar is the clear default. Its technology pedigree, manufacturing scale, warranty terms, and bankability record are all verifiable. A.B. Energy, based on available information, is not a comparable manufacturer and would need significant independent due diligence before being considered for a financed project.
