DETERMINING THE TEMPERATURE COEFFICIENT
The tempreature coefficienct tells us how the module’s behavior wil change at different cell temperatures.
The measurement process
To determine a solar module’s temperature coefficient, a solar simulator is used to capture a current-voltage characteristic curve at 1,000 W/m² and an AM of 1.5. The solar module’s temperature is then increased in predetermined steps. By capturing the current-voltage characteristic curve at difference temperature points, we obtain module values like Pmpp, Impp, Vmpp, Uoc and Isc. Since current, voltage, and power vary at different temperatures, the temperature coefficiency for current, voltage, and power can be determined for a tested module.
Who can take advantage of this offer?
- A solar module’s temperature coefficient is an important selection criteria when planning a system. Thus, this measurement service is aimed at project planners, system planners and installers.
- Furthermore, this service is of interest to research institutes as well as dedictated system operators since it provides them with the possibility of using laboratory measurements to obtain data about their module’s temperature coefficient.
