Abstract

The invention discloses a system for directly heating through solar photovoltaic power generation. The system comprises a solar device, wherein the solar device is selectively connected with a direct current-direct current converter and a direct current-alternating current inverter through a selective switch; the direct current-alternating current inverter is connected with an alternating current distributor, and the alternating current distributor is connected with the State Grid Corporation of China and an electric appliance in a building specified by a user; and the direct current-direct current converter is connected with a direct current distributor, and the direct current distributor is connected with an electric heating structure. In the daytime in winter, electricity generated by the solar device is used for heating an electric heating film, one part of heat is upwards transmitted into the building, and the other part of heat is accumulated in a heat storage layer to continuously release heat indoors at night. In summer, electricity can be continuously generated, the generated electricity can be supplied to the electric appliance in the building specified by the user, and redundant electric energy can be uploaded to the State Grid Corporation of China. If the load of the electrical appliance in the building exceeds the electric energy generated by a solar cell panel, the electric energy can be obtained by the State Grid Corporation of China, and thus the solar energy is utilized to the greatest extent.

Description

technical field [0001] The invention relates to the technical fields of heating, energy saving and environmental protection. Background technique [0002] Scientific research shows that excessive carbon emissions will lead to environmental problems such as climate warming and the greenhouse effect. In this context, all walks of life need to develop green energy technologies. [0003] In northern regions, heating in winter is a common demand of people. The use of solar heating can greatly reduce the carbon emissions required for the heating process, but it has the following problems: [0004] 1. There is no sunlight for heating at night. This problem can be alleviated by using heat storage technology. [0005] 2. There is no need for heating in summer, and the problem of equipment waste. [0006] Although the use of heat storage technology can alleviate the problem of no sunlight at night, there is also the problem that the speed at which the stored heat is released cann...
