Problems solved by technology

In this way, there is a problem that in this structural system, either the photovoltaic gang blocks the vacuum tube, or the vacuum tube blocks the photovoltaic panel, so that we cannot flexibly switch between the maximum power generation state and the maximum heat generation state; and, Since the photovoltaic panel and the vacuum tube are still independent of each other, the power generation efficiency of the photovoltaic panel is still unavoidable, resulting in a greater degree of waste of solar energy

Abstract

The invention provides a solar power generation and water supply integrated system, comprising a vacuum glass panel, a photovoltaic panel and a thermal insulation water collecting cavity, wherein the thermal insulation water collecting cavity is in a flat box shape with an opened front surface, the vacuum glass panel covers the opened front surface of the thermal insulation water collecting cavity and consists of double-layer glass, a vacuum layer is arranged in the double-layer glass, the photovoltaic panel is flatly paved in the vacuum layer, the back surface of the photovoltaic panel clings to the inner-layer glass of the double-layer glass, the photovoltaic panel is sequentially and electrically connected with an external charger and a storage battery through conductive parts, the thermal insulation water collecting cavity is filled with water and is communicated with a thermal insulation water tank through a water inlet pipe and a water outlet pipe, and one of the water inlet pipe and the water outlet pipe is connected with a circulating pump in series. The system can be flexibly switched between a power generation efficiency maximum state and a hot water generation efficiency maximum state, and the waste of solar energy is completely avoided, so that the solar energy comprehensive utilization efficiency is greatly improved.

Description

technical field [0001] The invention relates to the field of solar energy equipment, in particular to a comprehensive solar power generation and water supply system. Background technique [0002] As the world's energy becomes increasingly tense, new energy technologies have developed rapidly; among them, solar energy equipment has formed a large-scale industrialization and has been well popularized. However, current solar energy equipment is limited to solar water heaters and photovoltaic power generation devices; among them, solar water heaters mainly rely on vacuum tubes for heat collection, hot water is sealed in vacuum tubes, and conduct convective heat conduction with the water body in the water tank; photovoltaic power generation devices are mainly made of silicon wafers It is tiled and can convert the sunlight projected on its surface into electrical energy. However, in fact, the photoelectric conversion efficiency of photovoltaic panels is only about 15%, which means...
