Current source power characteristic measuring method e.g. for solar module, uses offset measurement of voltage across load capacitor and capacitor charging current

摘要

Measuring method uses a measuring circuit (1) for determining the voltage across a capacitor (5) acting as a load supplied from the current source, e.g. a solar module (4), together with the capacitor charging current, with a time offset between the voltage and current measurements. The temperature and solar radiation intensity for a solar module may also be measured. An Independent claim for a current source power characteristic measuring device is also included.
