Monitoring of MPPT regulation during temperature transient phenomenon in off-grid solar system

During temperature transient phenomenon the electrical parameters of solar cell change rapidly. Increasing temperature affect decreasing voltage, which requires the rapid intervention of the control circuit to find a new maximum power point. The investigated solar panel works under laboratory conditions in an off-grid system. Battery pack and DC load have been also connected to the MPPT (Maximum Power Point Tracking) to simulate the normal operation.
