PURPOSE: A lifetime testing method for a solar cell module is provided to establish a condition causing malfunction of components forming the solar cell module, thereby calculating failure ratios of the components and calculating the service time of the solar cell module base on the calculated. CONSTITUTION: A lifetime testing method for a solar cell module (100) is as follows. A failure ratio is calculated by exposing components of the solar cell module to a condition causing malfunction. The calculated failure ratio of the components is applied to a formula calculating a failure ratio of the solar cell module so that the failure ratio of the solar cell module is calculated. The components of the solar cell module are a back sheet (150), an EVA sheet, an electrode, and a ribbon wire. The back sheet and the EVA sheet are exposed to a condition causing dew condensation, so that a failure ratio which is the probability of separation is calculated. The ribbon wire and the electrode are applied to a heat-cycle test condition so that a failure ratio which is the probability of cracks is calculated. |
