Product reliability has always been our top design priority. Our panels are rigorously tested to achieve a durability compatible with our 25-year warranty.

In fact, we test our products under much harsher conditions than mandated by official certification standards. We also expose them to harsh outdoor environments such as the Arizona desert and the Antarctic:

Accelerated lifetime testing is possible through specialized equipment that performs many –40°C to +85°C heat cycles per day, that exposes solar cells to intense UV light, and that exposes them to intense humidity. This has made it possible for us to study potential degradation mechanisms at accelerated time scale during product development.

During production, we continuously perform tests on randomly sampled production output in the form of accelerated lifetime tests under simulated high-stress conditions in indoor environmental chambers.
