With the increasing importance of renewable energy, solar photovoltaic systems have become an important energy solution. However, these systems must operate in a variety of climate conditions, from sweltering summers to humid rainy seasons. To ensure the reliability and durability of photovoltaic modules, damp heat test of photovoltaic modules is a key evaluation tool. The Damp Heat Test Chamber from Millennial Solar is a great helper in ensuring the reliability of your solar power generation system.

Photovoltaic module damp heat test

The purpose of the photovoltaic module damp heat test is to simulate the performance of the solar system under high temperature and high humidity conditions. This test places PV modules in an environment with high temperatures and humidity to simulate the challenges that a humid climate and long-term use can bring.

During the test, keep the test environment temperature at (85±2)℃, the relative humidity at (85±5)%, and the test time is 1000~1048 hours.Depending on the purpose of the study, long-term trials can provide more information about the performance of PV modules. Keep the module in an open circuit state at a temperature of (23±5)°C and a relative humidity of less than 75%. After leaving it for 2 to 4 hours, check whether there are any serious appearance defects described in item 8 of IEC 61215-1, and conduct the wet leakage test.

After the test, conduct electrical performance testing of the photovoltaic modules, including efficiency, current output and voltage characteristics, to evaluate the functionality of the modules. Finally all the data is collected and analyzed. By comparing the data before and after the test, the performance changes of photovoltaic modules under high temperature and high humidity conditions are evaluated.

Introduction:

Solar modules will withstand various harsh weather tests during their application. Among them, the performance of photovoltaic modules such as their ability to withstand high temperatures, high humidity, and long-term moisture penetration needs to be evaluated. The damp heat test is used to verify and evaluate the reliability of photovoltaic modules or materials and to identify manufacturing defects early through thermal fatigue-induced failure modes.

Long-term leakage current will cause changes in the state of the cell carriers and depletion layer, corrosion of the contact resistance in the circuit, electrochemical corrosion of the packaging materials, etc., resulting in cell power attenuation, increase in series resistance, light transmittance, etc. Degradation, delamination and other phenomena that affect the long-term power generation and life of components.

Photovoltaic module damp heat test is an important tool to evaluate the reliability and performance of solar module systems. It can improve the life and performance of the system by ensuring the reliability of the modules under various climatic conditions. This will promote the further development of solar technology so that it can operate efficiently in various climate conditions, which is crucial for the sustainable growth of the renewable energy industry. The Damp Heat Test Chamber developed by Millennial Solar helps you achieve optimal energy production and return.
