Solar simulation test equipment for photovoltaic panel
Atlas Material Testing Technology

Atlas introduces the Atlas 25Plus™ test program for determining the durability of photovoltaic modules, combining state-of-the-art instrumental and outdoor exposure testing.

Existing test standards such as the IEC module design qualification tests do not address long term durability issues. These tests are designed to reveal potential design or manufacturing defects resulting in early "infant mortality" failures. They are not intended or able to predict the longer term degradation or failure modes resulting from the accumulated damaging effects of climate related stresses.

Drawing on over 90 years' experience as the innovation leaders in weathering test methods and equipment, 25+ of those years being in photovoltaics beginning with module testing for Skylab, Atlas has developed the Atlas 25Plus PV module durability testing program. This program consists of a comprehensive battery of accelerated tests integrating both laboratory and outdoor environmental exposures targeting the long-term product "wear-out" period that can result in declining module performance or outright failure.
