Fotovoltaikte ultraviyole yaşlandırma test odaları kullanılmaktadır. (Güneş pili) field to evaluate the durability and weatherability of solar photovoltaic materials and modules under long-term ultraviolet light. It can simulate environmental conditions such as solar radiation, temperature and humidity, and perform accelerated aging tests on photovoltaic materials and modules to evaluate their performance and life prediction in the actual outdoor environment.

Özel uygulama
The following are some specific aspects of UV aging test chamber in photovoltaic applications:

Evaluation of material weather resistance: photovoltaic materials, silikon gofretler gibi, arka planlar, packaging adhesives, vesaire., will be affected by ultraviolet light, sıcaklık değişimi, humidity and other factors when exposed to outdoor environment for a long time. The UV aging test chamber can simulate these external conditions and evaluate the weatherability and anti-aging properties of materials through accelerated aging tests.

Modül performans değerlendirmesi: Fotovoltaik modüller (photovoltaic panels) are the core part of the photovoltaic system, whose performance and life are crucial to the efficiency and reliability of the system. The stability of photovoltaic conversion efficiency, sıcaklık özellikleri, power attenuation and loss of photovoltaic modules can be evaluated through long-term ultraviolet irradiation and environmental simulation in the ultraviolet aging test chamber.

Material optical performance test: The optical performance of photovoltaic materials is an important factor to determine its energy conversion efficiency. Ultraviolet aging test chamber can be used to test optical characteristics of photovoltaic materials such as transmittance, reflectance and absorptivity, so as to evaluate the optical stability and photoelectric conversion efficiency of materials under ultraviolet radiation.

Assessment of resistance to salt spray: Bazı alanlarda, salt spray in Marine environments can cause corrosion and damage to materials and components of photovoltaic systems. The UV aging test chamber can simulate the salt spray environment and conduct salt spray corrosion tests on photovoltaic materials and modules to assess their salt spray resistance and corrosion resistance.

Heat resistance evaluation: Photovoltaic modules need to be able to work stably at high temperatures. By simulating the high temperature environment in the ultraviolet aging test chamber, the thermal aging test of photovoltaic modules can evaluate the heat resistance, temperature coefficient and heat loss and other performance indicators.
