Solar photovoltaic modules are an important part of the renewable energy field. They convert sunlight into electrical energy and make important contributions to clean energy production and the reduction of greenhouse gas emissions. However, solar modules require long-term exposure to changing meteorological conditions and maintain efficient operation. Photostability Chamber from Millennial Solar is specifically designed to simulate solar radiation and meteorological conditions to evaluate performance changes of photovoltaic modules under various environmental conditions.

What is photovoltaic module stability testing?

Stability testing is an experimental method used to evaluate the performance changes of photovoltaic modules under different lighting and meteorological conditions. Designed to simulate the various environmental factors that PV modules may face throughout their lifetime, such as UV radiation, temperature changes, humidity and atmospheric chemicals. By simulating these conditions, you can better understand how solar modules will perform in real-world applications, thereby improving their reliability and durability.

Why perform photostability testing?

● Long-term performance evaluation: The design life of solar modules is usually between 20 and 30 years, so it is necessary to ensure that they can work stably and efficiently during this period. Photostability testing can simulate years of use and help determine whether solar modules will degrade in performance due to long-term exposure to light and weather conditions.

● Improved reliability: Solar systems are usually installed outdoors and exposed to harsh weather conditions, such as high and low temperatures, ultraviolet radiation and humidity. Photostability testing can evaluate the performance of solar modules, thereby improving system reliability and reducing maintenance costs.

● Quality control: Photostability testing can also help manufacturers identify potential quality issues. If it performs poorly in testing, manufacturers can take steps to improve the product's design and manufacturing processes and ensure product quality.
