Embodiment 1

[0024] This embodiment provides a small solar power station with integrated light and heat, the structure of which is as follows: figure 1 As shown, it includes a shallow water tank 1 and a solar solar power generation assembly 2, and the shallow water tank 1 is made of heat insulating material. The bottom of one side of the shallow water tank 1 is centered with a water outlet, and the other side of the shallow water tank 1 is provided with a first ball float valve 3, which is connected to the cold water tank 4 and controls the water level of the shallow water tank 1.

[0025] The number of solar power generation components 2 is 5-30 pieces. The solar power generation components 2 are filling junction box components. The solar power generation components 2 are arranged in parallel and fixed inside the shallow water tank 1. The upper surface of the upper surface is not immersed in water, and each solar power generation module 2 is connected in parallel and then connected to the...

Embodiment 2

[0031] This embodiment is similar to Embodiment 1, the difference lies in the connection mode of the solar power generation components 2, the solar power generation components 2 in this embodiment are connected in series, and the number of solar power generation components 2 is 5-30 pieces.

[0032] The working mode of this embodiment is the same as that of Embodiment 1.

Abstract

The invention discloses a small photothermal combined solar power station, which includes a shallow water tank and solar power generation components. The solar power generation components are arranged in an array in the shallow water tank, and water is injected into the shallow water tank to ensure that the upper surface of the solar power generation component is not soaked in In the water, each solar power generation module is connected in parallel or in series and then connected to the inverter and load placed outside the shallow water tank to form a distributed solar power plant; one side of the shallow water tank has a water outlet at the bottom, and the other side of the shallow water tank has a water outlet. There is a first float valve, the first float valve is connected to the cold water tank and controls the water level of the shallow water tank, the cold water tank is provided with a second float valve, the cold water tank is connected to the cold water circulation mechanism and the water inlet pipe through the second float valve, the cold water circulation mechanism The other end is connected to the water outlet through the first shut-off valve. The invention has the advantages of simple design structure, low cost, good heat dissipation and high power generation efficiency, and can fully collect and utilize the heat emitted by solar power generation components.

Description

technical field [0001] The invention relates to a solar power station, in particular to a small-scale photothermal combined solar power station, which belongs to the technical field of solar energy applications. Background technique [0002] At present, in the domestic solar photovoltaic industry, there are also attempts to use solar photovoltaic modules to design combined photothermal devices or power stations, but most of them collect the heat generated by the modules in the form of "collector tubes", which leads to scattered heat collection and low efficiency. , and cannot well reduce the temperature of the components during normal operation, and it is difficult to obtain good economic benefits. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the disadvantages of the prior art and provide a small solar thermal power station with simple structure, low cost, good heat dissipation and high power generation effic...
