ω s For each month representing the sunset angle of the level of the day, Z is the inclination angle, < >>
For local latitude, gamma is the installation azimuth angle of the photovoltaic module, delta is the declination angle of the sun, H d For the scattered radiation quantity of each month of the horizontal plane, H i Is the total radiation amount of each month on the horizontal plane.
8. The method for installing the three-dimensional layered photovoltaic module bracket is characterized by comprising the following steps of:
assembling the stereoscopic layered photovoltaic module bracket and the photovoltaic module panel according to any one of claims 1 to 7 into a truss on a tooling at a port and dock;
hoisting the truss and the tooling as a whole to a transport ship;
jacking the tool at the installation area so that the heights of the truss and the tool are higher than the pile foundation;
positioning the truss and the tooling to be right above the pile foundation;
lowering the truss and the tooling to an installation height;
and separating the truss from the tool, and installing the truss on the pile foundation.
9. The operation and maintenance method of the three-dimensional layered photovoltaic module bracket is characterized by comprising the following steps of:
acquiring the position of a photovoltaic module to be replaced;
judging whether the position of the photovoltaic module to be replaced is positioned in the middle layer of the three-dimensional layered photovoltaic module bracket according to any one of claims 1 to 7;
if the photovoltaic module is positioned in the middle layer, controlling the operation and maintenance ship to navigate to the rear of the middle layer, wherein the rear is the side, which is higher in inclination setting, of the photovoltaic module of the middle layer;
lifting the lifting ladder of the operation and maintenance inspection ship to the height of the photovoltaic module to be replaced;
unloading the photovoltaic module to be replaced, and transferring the unloaded photovoltaic module to the lower part of the later layer of the middle layer;
and installing a new photovoltaic module.
10. The method of operation and maintenance of a stereoscopic layered photovoltaic module bracket according to claim 9, further comprising:
if the photovoltaic module is not positioned in the middle layer, controlling the operation and maintenance overhaul ship to travel to the position of the photovoltaic module to be replaced of the first layer or the last layer;
lifting the lifting ladder of the operation and maintenance inspection ship to the height of the photovoltaic module to be replaced;
and disassembling the photovoltaic module to be replaced, and installing a new photovoltaic module.
11. The method of operation and maintenance of a stereoscopic layered photovoltaic module bracket according to claim 9, further comprising:
and controlling the operation maintenance overhaul ship to travel to the corresponding position of the photovoltaic module to be overhauled, and overhauling the photovoltaic module to be overhauled and the electrical equipment thereof.
