Photovoltaic heating equipment principle analysis

1. Conversion of solar energy into electricity

The principle of photovoltaic heating equipment is to use the solar photovoltaic effect to convert solar energy into electricity. When the sun shines on the photovoltaic panel, the photons will stimulate the electron transition and form an electric current. With the continuous development of solar technology, the conversion efficiency of photovoltaic panels has gradually improved, and the conversion efficiency of photovoltaic panels has reached more than 20%.

2, collector and heat exchanger

Photovoltaic heating equipment can not only convert solar energy into electricity, but also use collectors and heat exchangers to convert electrical energy into heat energy to achieve heating. The collector of photovoltaic heating equipment generally uses vacuum tube or flat plate collector, which can concentrate solar energy to a certain area and improve the efficiency of heat utilization. The heat exchanger is the key component that converts electrical energy into heat energy, which can convert electrical energy into water or air heat energy to achieve the purpose of heating.

3. environmental protection, energy saving heating methods

Photovoltaic heating equipment is an environmentally friendly and energy-saving heating method. Compared with traditional heating methods, it does not need to burn fossil fuels, does not produce harmful gases such as carbon dioxide, and has less pollution to the environment. In addition, photovoltaic heating equipment can make full use of solar energy resources, achieve energy self-sufficiency, save energy consumption, but also reduce energy expenses.

The above is about the principle of photovoltaic heating equipment analysis. Photovoltaic heating technology has the advantages of environmental protection, energy saving and high efficiency, and is the development direction of future heating. (Article source: Love procurement)
