PV Module Preconditioning / Durability Performance Testing Since it is common for PV panels to be specified for 20 or more years of service, it is critical that the assessment their performance over prolonged exposure is understood. This is difficult to predict without actual empirical data and it is financially impossible to wait 5 or 10 years while this data is acquired. To ensure PV panel reliability, accelerated life testing must be performed. EYE Lighting / Iwasaki can provide systems designed specific to your product configuration, your test requirements, and your budget. This large-capacity UV accelerated life-cycle test chamber can measure the deterioration progress of solar cells/modules by irradiating them with a constant UV power up to five (5) times standard solar energy. Operating the chamber 24/7 produces an acceleration factor greater than 12. The impact of a full year of solar UV irradiation can be evaluated in just a month of testing. EYE / Iwasaki Solar UV Irradiation Preconditioning / Durability Systems Automatically controls UV ray irradiance. The lamp output is automatically adjusted to the prescribed strength (1-5SUN) by feedback from the value monitored by the UV ray irradiation sensor installed inside the chamber. Automatically recreates the conditions specified by the verification standards. Select the pre-programmed verification standard, "press the button" and automatically start the test according to the pre-set conditions such as temperature and irradiation strength. Constantly monitors the test progress according to the requirements for cumulative UV ray irradiance level prescribed by the IEC standard. As the cumulative UV ray level by each spectral range subject to monitoring is calculated from the value obtained by the UV ray irradiation sensor and the remaining time is displayed, the test progress can be monitored as needed.
