Photovoltaic tracking Mounting system to make full use of green resources

The photovoltaic tracking mounting system can completely solve the problem that photovoltaic power plants occupy a large amount of land resources and the land cannot be fully utilized, and ensure that the land under the photovoltaic panels is fully exposed to the sun.

1. What is the so-called active tracking:

On the premise of determining the latitude and longitude of the location of the photovoltaic power station, an active tracking scheme is designed according to the sun's trajectory at that location, and the optimal illumination angle of the module is preset, so that the tracking mounting will drive the photovoltaic module to the preset position in advance, and wait for the sun to follow the set position The illumination angle illuminates the photovoltaic module to generate electricity. Through the intelligent angle adjustment of the mounting in the east-west direction and the north-south elevation angle, it can be tracked in advance to increase the power generation.

The photovoltaic tracking mounting system has the following advantages:

(1). The unique feature of the present invention is that there is no light tracker and light sensor. Only one set of active tracking control system is used to automatically control photovoltaic mounting and photovoltaic panels. On the solar track during different periods, always advance a certain irradiation angle, and regularly wait for sunlight to increase power generation.

(2). Efficient and comprehensive utilization of land: to build a 100MW dual-drive tracking photovoltaic power station, covering an area of about 2400 acres, a photovoltaic mounting about 3.2m high (the height can be designed according to needs), vertical (horizontal) and single-row photovoltaic modules are installed at intervals (or double Rows), so that there is no shelter between the modules; the east-west span of the mounting is about 6m, and the north-south distance is about 13m, which meets the traffic operation requirements of agricultural machinery and fire fighting machinery; after the module height and spacing are arranged, 100% of the land under the module is exposed to sunlight 100% of the land is used comprehensively and efficiently. (Single-drive and dual-drive active tracking support will not affect agricultural planting and breeding, which can improve the growth, quality and yield of agricultural products, and reduce water evaporation).

(3). Long lighting time, increased power generation, and relatively shorter payback period for polycrystalline single-sided power generation modules, with annual power generation exceeding 1,560 hours (single crystal double-sided power generation with dual-drive tracking, annual power generation exceeding 1,650 hours). Compared with fixed installations, power generation increases by more than 25% per year.

(4). The active tracking mounting system uses the original technology of active tracking and anti-mask callback functions to specifically protect the "anti-mask" between the front, rear, left and right component callback functions. It occupies a small area and the mounting system has a long service life.

(5). Strong wind resistance: adopt single-row photovoltaic panels (horizontal and vertical) spacing arrangement, sufficient row spacing, air circulation, rapid exhaust, small wind load per unit area, and reduce the positive and negative pressure of the wind on the components. , Extend the service life of components.

(6). High reliability and low maintenance cost: the active tracking mounting adopts galvanized square steel pipe and round steel pipe; the rotating part adopts the shaft pin design, which is lubrication-free, and guarantees the service life of 25 years. It adopts single-row photovoltaic modules (horizontal and vertical) spacing arrangement. There is sufficient exhaust spacing between the air circulation, rapid exhaust, and small wind load per unit area, which reduces the probability of component cracking caused by the positive and negative pressure of the wind on the component, and extends the service life of the component; the grid is hard-connected between the pillars , Forming a whole, greatly improving wind resistance.

(7). Due to the active tracking according to the characteristics of tracking, the components will change different rotation angles every day. Dust and floating objects in the air are not easy to adhere to the components. Even if small dust particles fall on the components, if it rains, the dust will be easily washed away by the inclination of the components; in heavy snowy weather, the snow falling on the module will quickly fall on the module with the change of the inclination angle of the module. On the ground, power generation is basically not affected; when birds fly near the module, due to the interval installation and tracking and rotation characteristics of the module, the number and time of bird landing will be greatly reduced, thereby reducing the amount of bird droppings and the production of the module. The probability of hot spot influence, in order to extend the service life of the module and improve the power generation efficiency of the module.

2. Technical features display and application scope

"No cleaning": The components change different rotation angles every day. Dust and floating objects in the air are not easy to adhere to the components. Even if the small dust particles fall on the components, once it rains, the dust can be easily washed away by the rain with the help of the inclination of the components. Active tracking photovoltaic support has unique innovation, scientificity, practicability and maintenance-free. It can be widely used in centralized and distributed photovoltaic power generation. It is especially suitable for photovoltaic poverty alleviation, old power station renovation, complementary agriculture and photovoltaic complementary fishing (surface photovoltaic), photovoltaic farming, home courtyards, streets and lanes, factory roofs, greenhouse renovation, sewage treatment plants, highway ramps, service areas, etc. Can be constructed The field of photovoltaic power plants.
