Photovoltaic cell modules are expected to withstand a variety of outdoor weathering conditions without affecting functionality. Assured Testing Services is capable of providing many of these tests, including salt spray, humidity, UV exposure, acid rain simulation, ammonia exposure (IEC 62716) and thermal cycling. Some of these tests are referenced by industry standards such as IEC 61215 and IEC 61646.
