researchers from Chalmers University of Technology in Sweden and the Universitat Politècnica de Catalunya – Barcelona Tech.An innovative hybrid solar device that combines a PV panel and energy storage has achieved record levels of energy storage efficiency for such a device.which causes panel temperature to increase and – somewhat counterintuitively – results in a 10% to 25% decrease in the efficiency of PV cells.

developing such a device involves overcoming a couple of key challenges to ensure the system operates efficiently.have come up with a novel hybrid device that addresses both of these issues while maximizing solar energy utilization and achieving record energy storage efficiency.

The solar hybrid system combines photovoltaic (PV) panels and an energy storage system in the one device
