Problems solved by technology

[0002] The existing solar water heaters use glass vacuum tubes to directly collect solar heat to heat the water in the tubes, and then send the hot water into the house through the delivery pipes. This heating method has the disadvantages that the glass vacuum tubes are easy to burst and the delivery pipes are easy to freeze. The problem, especially in the north, is that the temperature is low, and the pipeline is easy to freeze, which makes it impossible to transport hot water, and during the transportation of hot water, the heat is lost through the pipeline, and there is a shortage of heat loss; in addition, when using heat When using water, it is necessary to discharge the cold water in the pipeline first, resulting in a waste of water resources

Abstract

The invention discloses a photovoltaic water heater which comprises a photovoltaic panel assembly, a water storage tank, a first controller and a heating element. The heating element is arranged in the water storage tank and is a low-voltage heating rod, the water storage tank is arranged in an indoor environment, a first temperature sensor is arranged in the water storage tank and is connected with an input end of the first controller, the photovoltaic panel assembly is connected with the low-voltage heating rod by a wire and a first control switch, and the first control switch is connected with an output end of the first controller. The photovoltaic water heater has the advantages that the low-voltage heating rod is used as the heating element, and can be normally started to work under the condition of insufficient illumination, accordingly, water can be heated, the problem that water can be heated by the aid of light energy only under the condition of sufficient illumination in the prior art can be solved, and the light energy conversion efficiency can be improved.

Description

technical field [0001] The invention relates to the technical field of photovoltaic cell applications, in particular to a photovoltaic water heater. Background technique [0002] The existing solar water heaters use glass vacuum tubes to directly collect solar heat to heat the water in the tubes, and then send the hot water into the house through the delivery pipes. This heating method has the disadvantages that the glass vacuum tubes are easy to burst and the delivery pipes are easy to freeze. The problem, especially in the north, is that the temperature is low, and the pipeline is easy to freeze, which makes it impossible to transport hot water, and during the transportation of hot water, the heat is lost through the pipeline, and there is a shortage of heat loss; in addition, when using heat When using water, it is necessary to discharge the cold water in the pipeline first, which will cause a waste of water resources.
