Embodiment Construction

[0023] The present invention is a photovoltaic heating system that responds to changes in incident solar radiation. Specifically, for any given incident solar radiation, the photovoltaic heating system dynamically delivers the maximum power from the photovoltaic array to the resistive heating assembly. The working principle and operation method of the present invention can be understood more easily with reference to the drawings and accompanying drawings.

[0024] Go to attached image, figure 1 Shown is a non-limiting preferred embodiment of a photovoltaic heating system, generally designated 20, comprising a photovoltaic (PV) cell array 2, a maximum power point tracking (MPPT) circuit 3, and at any given solar radiation, the MPPT circuit 3. Extract the maximum power from the PV array 2 as much as possible, and convert the voltage connected to the maximum power point into the driving voltage for driving the resistive heater 21, which is immersed in the medium 1a in the contai...

Abstract

A photovoltaic cell array, one or more heating elements, and a maximum power point tracking circuit are configured to track the maximum power point of the photovoltaic cell array and to provide that maximum power collectively to the heating element(s).

Description

technical field [0001] The invention relates to the field of solar energy, in particular to a photovoltaic array that changes the conditions of incident sunlight radiation by heating with maximum power. Background technique [0002] It is well known that in non-electrical solar heating panels, water is heated by flowing through heating tubes that absorb solar radiation energy, and that free flow within the heating tubes is essential for good performance of the panels. In cold climates, where the ambient air temperature is below the freezing point of water, it is very likely that the water in the heater tube will freeze and crack the heater tube. Therefore, a durable solar heating system that can work in low temperature conditions is necessary. [0003] US Patent No. 5,293,447 discloses an electrical solar heating system implemented with a photovoltaic array to adjust the resistive load or generation parameters of the photovoltaic array to maximize power transmission efficie...
