Construction and Simulation of a Water Cooling System Controller for PV Modules: Some Initial Results
In recent years, equipment for the use of solar energy has been actively developing in the world, which provides heat and electricity. In particular, photovoltaic technology using photovoltaic modules is widely used. This paper focuses on cooling controllers for the surface of photovoltaic modules to reduce surface temperatures, increase their output power and improve the performance of photovoltaic systems. The paper presented the design, simulation and construction of water cooling system controller for photovoltaic modules. The application of water cooling system controller for grid-connected photovoltaic system with 250 Wp has brought good results. The experiments were conducted at Central Vietnam, the water cooling system controller is set to automatically work so that when the surface temperature reaches 40oC, after each operation the power of the grid-connected photovoltaic system increased significantly. The results also indicate that the power consumption of the water cooling system controller is much smaller than the increased power of grid-connected photovoltaic system.
