Stacked solar photoelectricity and photothermal combined electric heating system

Abstract

The invention discloses a stacked solar photoelectricity and photothermal combined electric heating system. The stacked solar photoelectricity and photothermal combined electric heating system comprises a water heating region, a heat preservation water storage tank, a steam generation region and an energy converting region. The water heating region is provided with N solar cell panels which are connected in series, the cell panels are hollow and are internally provided with supports, and the supports are provided with solar hot water generators. The front end of the water heating region is provided with a water inlet. The heat preservation water storage tank communicates with the water heating region and the steam generation region. The steam generation region is provided with 3N solar cell panels which are connected in series. Solar hot water generators in the steam generation region are connected with steam generators, the solar hot water generators are connected with vacuum pipes, and the vacuum pipes are connected with vacuum pumps through electromagnetic valves. A steam outlet of the steam generation region is connected with a heat accumulator, the heat accumulator is connected with a turbine and a generator, and a power grid is connected through a transformer. The stacked solar photoelectricity and photothermal combined electric heating system is novel in structure and convenient to use, under the situation that power generation of the solar cell panels is not affected, solar energy can be used for heating water to be used, generating steam to be used and generating power through the steam, and the utilization rate of the solar energy is increased.

Description

technical field [0001] The invention belongs to the field of solar photovoltaics, and in particular relates to a superimposed solar photoelectric photothermal composite electric heating system. Background technique [0002] Solar energy is a renewable resource with many advantages such as large amount, harmless and universal. The history of human use of solar energy can be traced back to ancient times when people used sunlight to dry items and make food. Nowadays, solar panels refer to devices that directly or indirectly convert solar radiation energy into electrical energy through the photoelectric effect or photochemical effect, but solar panels can only use light energy to generate electricity alone, and the photoelectric conversion rate is low, only 13%, which is a problem. The conundrum of the universal use of solar energy. Contents of the invention [0003] In order to solve the above problems, the present invention discloses a superimposed solar photoelectric phot...
