One-piece flat-plate solar photo-thermal and photoelectric system

Abstract

The invention discloses a one-piece flat-plate solar photo-thermal photovoltaic system. The one-piece flat-plate solar photo-thermal photovoltaic system comprises a flat-plate solar heat collector, a solar photovoltaic power generating panel, a water tank, a circulating water pump, a storage battery, an inverter and a controller, wherein the flat-plate solar heat collector is provided with a tubular heat absorber, a water inlet of the tubular heat absorber is connected with the water tank through a first pipeline, and an outlet of the tubular heat exchanger is connected with the water tank through a second pipeline; and the circulating water pump is arranged on the first pipeline and electrically connected with the controller. The one-piece flat-plate solar photo-thermal photovoltaic system further comprises a thermoelectric power generating system, wherein the thermoelectric power generating system comprises a cold water circulating system, a third pipeline connected between the first pipeline and the second pipeline and a thermoelectric power generating fin; and the hot end of the thermoelectric power generating fin is connected with the third pipeline, and the cold end of the thermoelectric power generating fin is connected with the cold water circulating system. The one-piece flat-plate solar photo-thermal photovoltaic system has high solar utilizing rate and can meet the requirements of users on hot water in rainy days.

Description

technical field [0001] The invention relates to the field of water heating facilities, in particular to an integral 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. Early solar water heaters mostly used 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 the antifreeze solar energy recommended by CN1027661C for example. Water heater, the all-plastic integrated solar water heater introduced by CN1399110A, the capped anti-hail solar water heater provided by CN2879040Y, the anti-hail solar water heater with a movable cover disclosed...

AI Technical Summary

Problems solved by technology

However, both solar photovoltaic modules and flat-plate solar collectors have the problem of being affected by the weather. Specifically, it is often difficult or even impossible to meet people's requirements for hot water in rainy and snowy weather without solar radiation. Moreover, there is no technical inspiration that can make up for this defect in published patents and non-patent literature
