Description
Technical Field
The utility model belongs to the technical field of solar photovoltaic, and particularly relates to an offshore photovoltaic power generation tracking device and a photovoltaic power generation system based on a latitude area in a northern hemisphere.
Background
The power generation efficiency of the photovoltaic at sea is always a hot problem, and the power generation efficiency can be enhanced through the design of various systems, such as a cooling system, a cleaning system, a tracking system and the like, and the design of the photovoltaic tracking system at sea is one of technical difficulties. The offshore photovoltaic power generation system can utilize a tracking system to maximize productivity efficiency. While the industry is inclined to design a simple floating body structure, the optimal design of the tracking system is more beneficial to increase the power generation efficiency.
For each specific latitudinal location and moment on earth there is an optimal arrangement of solar photovoltaic panels which provides the highest power generation performance. The tracking system is therefore designed to maximize the energy gain over the lifetime of the offshore photovoltaic system.
Solar trackers are categorized by drive system as active, passive, semi-passive, manual, and chronological. Unlike terrestrial photovoltaic environments, photovoltaic panels are floating due to wave motion in the marine environment, and thus conventional terrestrial photovoltaic panel arrays employ fixed inclinations, which are somewhat inefficient in terms of power generation. In addition, scholars have proposed to use a dual-glass photovoltaic panel, which receives solar energy from both sides of the panel, thereby improving the efficiency of collecting solar energy. Although a solar photovoltaic unilateral positioning sun tracking system (grant bulletin number is CN 105262419B) is proposed, the maximum movable angle range of the photovoltaic module is 45 degrees, and the maximum movable angle is not the optimal angle when the sun directly enters the south-back line; and the sun rises from the east, and when the west falls, the unilateral photovoltaic panel cannot meet the backlight time period, and the sun illumination is not fully utilized.
The existing mode can indeed enhance the power generation efficiency of the solar energy of the photovoltaic panel to a certain extent, but cannot achieve the maximization. The ocean area of China is wide, most of the ocean areas are distributed in the middle and low latitudes of the northern hemisphere, the direct solar energy is rich in the low latitude areas, and the middle and latitude areas are small in solar altitude angle because the direct solar energy points move back and forth between the north and south regression lines of the low latitude. Therefore, an optimal inclination angle of the photovoltaic panel needs to be designed, so that the photovoltaic panel surface is perpendicular to the incident rays of the sun, and the collected solar energy can be maximized.
