Temperature humidity environmental test chambers are capable of simulating a variety of temperature and humidity conditions for climatic testing, which comes in a variety of sizes and performance configurations and offers an ideal solution for any industry or product. Note: 1.Chamber working room size could customize. 2.If test specimens have active load during test, please inform us. 3.This is temperature humidity model, if need make temperature test only, please refer to temperature chambers.

Steady-state solar simulators, also known as continuous solar simulators, are light sources that provide constant illumination over time. They are used to measure the output performance of solar thermal collectors and photovoltaic modules without being affected by weather conditions. A solar simulator is a light source that has specific quantifiable similarities to natural sunlight, namely in its spectral distribution and intensity. It may also be referred to as an artificial sun or sunlight simulator. The purpose of a solar simulator is to provide a consistent, controllable source of illumination in a laboratory environment. The most commonly discussed three areas of similarity are: spectral match, spatial non-uniformity, and temporal instability.

PID tester (potential induced degradation) is a type of deterioration that occurs in solar power generation systems. It is caused by leak current created by a large potential difference generated between a PV module frame and module circuit. PID is considered to be a factor responsible for solar power generation system output drops, and to be promoted by humidity. Accurate PID evaluation requires leak current measurement after applying a high voltage in a high-temperature/humidity environment with high precision and reproducibility.

Environmental chamber for Thermal Cycling and Humidity-Freeze Test are environmental tests that can be used to evaluate the performance of PV modules in extreme weather In Humidity-Freeze Test, PV modules are subjected to cycling between temperatures 85°C with relative humidity 85 % and -40°C. PV modules are subjected to 10 complete cycles in the closed climatic chamber in accordance with the profile on the picture bellow. The purpose is to determine the ability of the module withstand against humidity penetration. Thermal cycling tests are done for PV module certification, a current within +/-2 percent of the current measured at the peak power when the temperature of the solar module is above 25° C should be injected. The tested solar module is subjected to the cycling temperature limits of an extreme low temperature of – 40°C ± 2°C and an extreme high temp of + 85°C ± 2°C .
