Abstract
The need to optimize the operation of photovoltaic modules inevitably arises with the development of green energy production technology. In order to achieve a good technological yield, durability and efficiency in production, continuous studies and innovations are required. This study focuses on simulating the operation of water-cooled and uncooled PV modules in order to understand the temperature-dependent PV operation. This cooling module consists, in the first phase, of a copper coil through which water circulates, and in the second phase, of a coolant distributor/collector system. The module is attached to the lower surface of the photovoltaic panel, respectively to the teller foil layer. For this simulation we used the Ansys software package (Discovery, Fluent and Space Claim).
