SS/SD Series Test Chambers for Solar Panels
Tescor's Damp Heat Test Chamber for Solar Panels assists in developing cost-effective and reliable PV modules and solar panels for the energy industry. The chamber's damp heat test is performed according to IEC 61215 and IEC 61646 standards. With this test, the PV module's ability to withstand the effect of long-term penetration of humidity can be accurately determined. PV modules are subjected to temperatures upwards of 85°C and relative humidity of 85% for 1,000h in the climatic chamber. After the test, the PV modules are analyzed, and those with a damaged PV cell reveal which will experience significantly decreased power in certain environmental conditions. Through the damp heat test, the chamber can prove the reduction of durability resistance of PV modules to the long-term effect of humidity
The Thermal Cycling Test Chamber for Solar Panels performs thermal cycling tests in accordance to IEC 61215, an accelerated test protocol to evaluate module quality and reliability standards. For high power photovoltaic (PV) modules, one of the most critical aspects is the duration for which the module can produce useful power. The purpose of the IEC 61215 test is to determine the ability of the PV module to withstand effects of large temperature variations - analyzing material fatigue and temperature stresses, amongst others. These rapid temperature changes range from 100°C to -40°C, putting a strain on the PV module so that the different coefficients of thermal expansion of parts of the PV module shows defects like poor soldering, cracked cells, delamination, performance reduction and insulation resistance. Reliability and lifespan of PV modules are key factors to system performance and warranty, and the Thermal Cycling Test Chamber for Solar Panels can accurately test PV durability.
