MEASURING WEAK LIGHT BEHAVIOR
The main goal of this measurement is to obtain information on a solar module’s specific behavior under different irradiation conditions.
The measurement process
When determing weak light behavior, a PV module’s current voltage curve is measured with a solar simulator. The measurement occurs at a homogenous cell / module temperature of 25 °C and an air mass of 1.5. Unlike power measurements, which use an irradiation of 1,000 W/m², the solar simulator’s irradiation is increased from 100 W/m² to 700 W/m² in predetermined steps.
Measurement results and their documentation
Measurement results reflect the module’s electrical parameters at an irradiation of 100 W/m², 200 W/m², 400 W/m² and 700 W/m². A graphical and tabular representaiton of the data is provided as a test report.
Who can take advantage of this offer?
- A solar module’s weak light behavior is an important selection criterion when planning a PV system. Thus, this measurement is aimed at project planners, system planners, as well as installers.
- Furthermore, this test is naturally of interest to research institutes as well as dedicated system operators, since it provides them with an opportunity to obtain information about their solar module’s specific weak light behavior with the help of laboratory measurements.
