It contacts to make the power on/off fabric connectivity with the first iron block 20, the second iron block 16 respectively when in first position, not locate
It separates to disconnect the power on/off structure with the first iron block 20, the second iron block 16 respectively when first position, the electromagnetism
Iron block 15 has the first terminals and the second terminals, is greater than default power generation function for the generated output in second photovoltaic panel
So that the mobile iron block 17 is moved to first position when rate, is also used to be less than or equal in the generated output of the second photovoltaic panel default
The mobile iron block 17 is set not move to first position when generated output.
Specifically, 2 electricity of the second photovoltaic panel be mainly used for electromagnet block 15 be passed through electric current generate attract magnetic field pull move
Dynamic iron block 17 moves up, and mobile iron block 15 is automatically moved to corresponding position according to the generated output size of the second photovoltaic panel.
When the second photovoltaic panel does not generate electricity, electromagnet block 15 is not passed through electric current, and mobile iron block 17 is not inhaled by electromagnet block 15
Draw and be moved to the second position (position in Fig. 8), move iron block 17 at this time and do not contacted with the first iron block 20, the second iron block 16, leads to
Cut-off structure disconnects.
When the generated output of the second photovoltaic panel is less than or equal to default generated output, although electromagnet block 15 is passed through electricity
Stream, but electric current is little due to being passed through, the attraction of generation are less than the pulling force of spring, and mobile iron block 17 is moved to first position and the

When the generated output of the second photovoltaic panel is greater than default generated output, electromagnet block 15 is passed through biggish electric current, produces
Raw attraction is greater than the pulling force of spring, and mobile iron block 17 is moved to first position (in Fig. 9 by the attraction of electromagnet block 15
Position), iron block 17 is moved at this time to be contacted with each other with the first iron block 20, the second iron block 16, power on/off fabric connectivity.
It should be noted that power on/off structure in the present embodiment and not only limit and above structure, other are according to the second light
The generated output for lying prostrate plate realizes that the connection of power on/off structure and the structure disconnected are within the scope of the present invention.For example,
In above-mentioned power on/off structure, can no setting is required the first iron block, third terminals are connect with mobile iron block electric wire.
In the present embodiment, the waste heat of photovoltaic panel is recycled by the way that the water of photovoltaic panel front hollow layer is arranged in, and utilized
The light refraction of the water of preset shape changes the irradiating angle of the sunlight being irradiated in photovoltaic panel, makes the power generation of photovoltaic panel
Efficiency further increases.
Since for crystal photovoltaic plate, when temperature is more than 25 °C, temperature is every to improve 1 DEG C, and output power is reduced
0.4%~0.6%, for photovoltaic panel in actual power, many times plate temperature is above 25 °C, especially in summer, when high
Plate temperature can reach 50 °C or so, cause the generating efficiency of photovoltaic panel very low, cannot effectively improve in the summer of intensity of illumination abundance
The generated output of photovoltaic panel, plate temperature, should in 50 °C or so of period when emphasis recycling summer photovoltaic panel power generation in the present embodiment
The generating efficiency of period photovoltaic panel is influenced to reduce more by high temperature.
Based on the above principles, the temperature of photovoltaic panel is reduced by the way that water layer is arranged in photovoltaic panel front in the present embodiment, it is thick
Lesser water layer sunlight transmittance is spent 90% or more, when the positive sunlight intensity of illumination of photovoltaic panel is larger, although water layer
The intensity of illumination for being irradiated to photovoltaic plate surface can be reduced to a certain degree, but by water layer to reduce the increased light of photovoltaic plate temperature
The generated output that plate generated output is reduced much larger than intensity of illumination and lost is lied prostrate, while the water layer of arc shape (can regard water production as
Made of half convex lens) direction of illumination of also changeable sunlight in sunlight oblique illumination, make vertical irradiation to photovoltaic panel
Positive sunlight intensity of illumination further enhances, and effectively increases the generating efficiency of photovoltaic panel.
In addition, since the temperature of photovoltaic panel and the air themperature of surrounding are mainly influenced by the radiation intensity of sunlight, the sun
Light radiation intensity is bigger, and the surface of photovoltaic panel more needs to cool down, and is sentenced in the present invention by the way that the second photovoltaic panel of small size is arranged
The radiation intensity of disconnected sunlight, when solar radiation intensity is very big, the generated output of the second photovoltaic panel will be greater than default hair
Electrical power carries out cooling and waste heat recycling, when sunlight intensity is smaller, second to make the cold water of feed water inlet enter hollow layer
The generated output of photovoltaic panel will be less than or equal to default generated output to make the hot water in hollow layer flow into water tank or
Cold water is not passed through in hollow layer to cool down, whole process passes through without installing corresponding temperature monitoring system and control device
Power on/off structure achieves that corresponding automatic control, which is less prone to failure in outdoor application for a long time, and answers
With cost is relatively low.
Protection scope of the present invention is not limited to foregoing description, and any other forms under the inspiration of the present invention produce
Product, no matter making any change in shape or structure, the technical schemes that are same or similar to the present invention, in this hair
Within bright protection scope.

Two iron blocks (16) are mounted on the upper right quarter of the insulating element (21) and are spaced the first pre-determined distance with the electromagnet block (15)
Position, the upper end of the spring (18) is fixed on the lower part of the mobile iron block (17), and lower end is fixed on the location hole
(19) bottom, the mobile iron block (17) at least have first position, be in first position when respectively with the first iron block
(20), the second iron block (16) contact is to making the power on/off fabric connectivity, when being not at first position respectively with the first iron
To make the power on/off structure disconnect, the electromagnet block (15) has the first wiring for block (20), the second iron block (16) separation
End and the second terminals make the mobile iron block when being greater than default generated output for the generated output in second photovoltaic panel
(17) it is moved to first position, is also used to make when the generated output of the second photovoltaic panel is less than or equal to default generated output described
Mobile iron block (17) do not move to first position.
