Split type flat-plate solar photothermal and photovoltaic system

Abstract

The invention discloses a split type flat-plate solar photothermal and photovoltaic system, and belongs to the technical field of water heating equipment. The system comprises a solar photovoltaic generation component, a flat-plate solar thermal collector, an adjustment controller, a storage battery, an inverter, a power supply control cabinet, a controller, a water tank and a circulating pump, wherein the solar photovoltaic generation component is connected with one end of the flat-plate solar thermal collector; the flat-plate solar thermal collector is provided with a pipe type heat absorber; a water inlet and a water outlet of the pipe type heat absorber are connected with the water tank; the adjustment controller is connected with the inverter; the inverter is connected with the power supply control cabinet; the power supply control cabinet is connected with the controller; the storage battery is connected with the adjustment controller; an electric heater is arranged in the water tank and is in electrical connection with the controller; the water tank is provided with a tank upper water level sensor and a lower water level sensor; and the circulating pump is arranged on a pipeline and is in electrical connection with the controller through a circuit. The invention has the advantages that the system avoids light influence, and meets requirements of the water tank for continuous water supply.

Description

technical field [0001] The invention belongs to the technical field of water heating facilities, and in particular relates to a split-type flat solar photothermal photovoltaic system. Background technique [0002] As people's awareness of energy conservation and environmental protection, as well as their awareness of protecting non-renewable natural resources such as oil, coal, and natural gas, continues to increase, the application of solar water heaters has gradually become popular. Most of the solar water heaters in the prior art use the structural form of vacuum tubes (also known as light-to-heat conversion glass tubes), and solar water heaters of this structural form can be seen in large numbers in Chinese patent documents, such as those recommended by CN1027661C for example. Antifreeze solar water heater, all-plastic integrated solar water heater introduced by CN1399110A, covered anti-hail solar water heater provided by CN2879040Y, hail-resistant solar water heater wit...

AI Technical Summary

Problems solved by technology

[0005]However, both solar photovoltaic modules and flat-plate solar collectors have the problem of being affected by the weather. Such weather is often difficult or even impossible to meet people's requirements for using hot water, and there is no technical inspiration that can make up for this defect in the published patents and non-patent literature.
