Household solar electrothermal combined-production combination system

Abstract

The invention discloses a household solar electrothermal combined-production combination system comprising a condensation device, a revolving device, a horizontal rotating device and a controller. The revolving device is connected with the condensation device; the horizontal rotating device is arranged at the bottom of the condensation device; the revolving device drives the condensation device to make rotation; and the horizontal rotating device drives the condensation device to make horizontal rotation. The condensation device collects solar energy that is not absorbed by a solar cell panel and leads the heat out for utilization. A light sensor is arranged on the condensation device. The controller uses the light sensor to detect an angle between solar light and a plane where the solar cell panel is located; the revolving device and the horizontal rotating device adjust an angle between the solar cell panel and the solar light. According to the invention, the redundant heat that can not be absorbed by the solar cell panel is led out and is utilized; and the sun is tracked, so that the sunlight irradiates the solar cell panel vertically all the time and thus the energy utilization rate of the solar energy is improved.

Description

technical field [0001] The invention relates to the technical field of solar power generation equipment, in particular to a household solar power-heat cogeneration system. Background technique [0002] At present, the photovoltaic photothermal device that everyone knows is to connect the solar panel to the water pipe through glass, air layer, PV board, adhesive layer, heat absorption layer, and directly transfer the heat on the solar panel to the water pipe. Heating is carried out, and finally the water is exported. However, such heat transfer efficiency is not very high, and the heat on the solar panel cannot be completely transferred to the water pipe, so that the temperature of the solar panel itself is still high, its power generation efficiency is still low, and the heat cannot be fully utilized, which eventually leads to It is still difficult to improve the comprehensive utilization rate of its energy to a large extent, and it is difficult to promote it.
