PHOTOVOLTAIC PANEL-FED DISTRICT SURFACE HEATER PRESSURIZED WATER HEATING SYSTEM

Abstract

The invention is a system that converts direct current (DC) energy obtained from photovoltaic (PV) panels (1) into heat for heating water, without the use of any inverter, directly into heat via multilayer and modular heating units (12) integrated into the outer surface of the water tank (6). The invention eliminates the risks of freezing, leakage, float failure and structural damage in classic rooftop solar energy systems; and the fatal electric shock and energy conversion losses in classic AC (220V) systems. The fact that the heaters do not come into contact with water prevents limescale formation, while the modular heaters, configured as at least two or more independent zones on the tank, ensure efficient hot water production even at low solar irradiation. The fact that the panels can be mounted on balconies, building facades or vertical surfaces increases the installation flexibility and safety of the system.
