Ultraviolet Aging Test Chamber is a laboratory testing system specifically designed for photovoltaic module ultraviolet preconditioning. The chamber simulates long-term outdoor exposure of photovoltaic modules to solar ultraviolet radiation, reproducing UV-induced material aging effects under controlled conditions. By accelerating natural ultraviolet exposure in a laboratory environment, the equipment enables evaluation of ultraviolet aging impacts that would normally take months or years outdoors, supporting verification of UV resistance and structural reliability of photovoltaic modules and encapsulation materials.
