Long-term testing
In the development of some types of solar cells, such as electrochemical cells (i.e. DSSC and Perovskite solar cells), aging measurements are crucial. Cells should be long-term test in a loaded condition and periodically measured their characteristics.
For this purpose, we have developed a special tracker of the maximum power point for power up to a few hundred mW. Due to its low power we named it micro MPPT - uMPPT. The circuit in addition to tracking also allows operation in open circuit, short circuit and at constant voltage.
The tracker is available as a six channels demo board, and as an instrument with hundreds of channels.
