AI Technical Summary

Technical Problem

Existing photovoltaic glass thermal shock resistance testing equipment cannot accurately simulate the temperature difference between day and night in desert areas, resulting in discrepancies between test results and actual usage conditions.

Method used

A photovoltaic glass temperature shock test device was designed, which uses a sliding heater and cooler. The power generation performance of the photovoltaic glass is tested alternately in high temperature and low temperature environments through a reciprocating storage box. Combined with a temperature sensor and control panel, precise temperature control and performance testing are achieved.

Benefits of technology

This improves the accuracy of performance testing for photovoltaic glass when used in special environments. By conducting multiple alternating tests, a trend graph of power generation performance changing with temperature is obtained, reducing the difficulty of location control and energy consumption.
