Performance Degradation Of Crystalline Silicon Solar Module In Various Ultraviolet Radiation Area

Polymeric materials are used for encapsulation of crystalline silicon solar modules to protect them against mechanical damage and environmental stress. The ultraviolet (UV) radiation is a key factor causing considerable damages for polymeric materials. UV Preconditioning Test of current qualification tests IEC61215 did not reflect the real condition during service life of 25 years. In this paper, a model of lifetime for PV modules exposed to different areas is developed. By this result, the solar modules are finely sorted according to different weather condition. This study also lays a foundation to further enhancing the encapsulant materials.
