PV mounting system has a variety of classification methods, such as welding type and assembly type according to the connection method, fixed type and daily type according to the installation structure, and ground type and roof type according to the installation location. No matter what kind of photovoltaic system, the structure of its bracket is generally similar, including connectors, columns, keels, beams, auxiliary parts and other parts. Fixed roof PV mounting system Fixed roof PV mounting system, as the name suggests, refers to a mounting system that keeps its orientation and angle unchanged after installation. The fixed installation method directly places the solar photovoltaic modules towards the low-latitude area (at a certain angle to the ground), and forms a solar photovoltaic array in a series-parallel manner, so as to achieve the purpose of solar photovoltaic power generation. There are many kinds of fixing methods, such as the pile foundation method (direct embedment method), concrete block counterweight method, pre-embedded method, ground anchor method, etc., and the roof fixing method has different schemes depending on the roofing material. . For different roofing materials, there will be different photovoltaic support systems: 1）Glazed tile roof PV mounting system As shown in Figure 1, glazed tiles are construction materials made of soft and hard materials such as alkaline earth and purple sand after extrusion, plastic pressing, and firing. The material is brittle and has poor load-bearing capacity. Picture 1 When installing the bracket, a specially designed main support member is usually fixed to the lower roof of the glazed tile to support the main beam and beam of the bracket. The support members such as the connecting plate are usually designed with multiple openings as shown in Figure 2, which is flexible and effective. Bracket position adjustment. Aluminum alloy pressing blocks are used for crimping between components and beams. Picture 2 2）Metal roof mounting system Metal plate is a steel formed by cold pressing or cold rolling of thin steel plate. The steel plate adopts organic coated thin steel plate (or color steel plate), galvanized thin steel plate, anti-corrosion thin steel plate (asbestos-containing asphalt layer) or other thin steel plates. Profiled steel plate has the advantages of light unit weight, high strength, good seismic performance, fast construction, beautiful appearance, etc. It is a good building material and component, mainly used for enclosure structures, floors, and other structures. Metal roof are generally divided into: upright seam type, bite type (corner type) type, buckle type (concealed type) type, and fastener connection (nail type) type. Picture 3 When installing a photovoltaic system on a metal roof, the shape and load-bearing capacity of the metal roof should be fully considered to determine the fixing method of the bracket. The fixing method of the matel roof bracket is mainly determined acc...

Roofs around the world can be broadly divided into domestic glazed tile roofs, concrete flat roofs and mental roofs. For the installation of rooftop solar power plants, "waterproofing" has to be considered a very important factor! The general principle of roof waterproofing is that it is better to guide than to block, i.e. in case of heavy rainfall, ensure that the nodes can be treated smoothly so that the water cascades off and the roof does not leak. Waterproofing of PV Mounting for Concrete Flat Roofs For new buildings with concrete flat roofs or villa concrete sloping roofs (covered with tiles), the bolts should usually be pre-built at the time of design and the roof waterproofed in accordance with conventional practice. For both types of existing buildings mentioned above, the roof structure should be identified first. When connecting the PV module base to the structural layer, the perimeter of the metal embed parts at the top of the base is the weak point for waterproofing. If not handled properly, rainwater can easily seep down into the structural layer from around the bolts of the buried parts, causing corrosion to the structural layer's reinforcing steel and creating a safety hazard. Waterproofing of PV Mounting Installation for Mental Roofs For mental roofs, the steel structure of the PV mounting system needs to penetrate the original waterproofing layer and the pressed steel sheets and be fixed to the main steel structure of the building. Then refer to the mental roof waterproofing practice for vapour barrier, insulation and waterproofing treatment. The focus of construction is on removing rust and corrosion, sealing, and applying a waterproofing coating to the substrate and periphery. For local leaks in mental roofs, a high quality neutral weather resistant sealant should be used to apply and seal them. For colour plates with severe localized corrosion, they need to be replaced before installing the PV modules. 1)For cases of colour steel plates with trapezoidal rib sections: The PV Mounting is usually connected to the colour steel plate from the side face or top side by means of self-tapping bolts. Self-tapping bolts must be supplied with matching weather-sealed waterproof gaskets. And after fixing the self-tapping bolts, the screws shall be coated with a high quality neutral weatherproof sealant. 2)For cases with cable sleeves through roof panels: Practices are available on existing national standard drawing sets. They can be used in design and construction to suit the actual project. 3)For cases with cables through roof panels: Waterproofing can be carried out using Dektite Cover. It is a roof waterproofing structure, often used in the presence of coloured pressed steel roofs, with good physical properties and chemical resistance to overcome problems such as leakage of rigid waterproofing materials. Waterproofing of the Roof Perforations Made by the Mounting Manufacturer For existing buildings with concrete flat roofs or villa conc...

In order to obtain maximum economic benefits for an ideal tracking photovoltaic power station, in addition to the technical breakthrough of panel direction, the Angle adjustment of photovoltaic support is also an important direction to increase energy efficiency. The photovoltaic panel can adjust the Angle to follow the sun, increase the direct light surface and effectively improve the power generation. The tracking photovoltaic bracket comes into being. The current photovoltaic market is mainly composed of three parts: structure, control and drive. The control system monitors the Angle of the module through the sensor and instructs the support to drive the photovoltaic module for tracking. Let's talk today One word tracking the core of photovoltaic support system operation - control system. #01  Tracking program Photovoltaic industry forefront tracking controller manufacturers have gradually begun to use AI autonomous learning algorithm and astronomical algorithm to optimize tracking Angle and improve power generation.

Color steel plate is generally used in light steel structure buildings, such as standardized workshops, warehouses, etc., according to its specifications, it is generally divided into angular color steel plate, right Angle locking type color steel plate and trapezoidal color steel plate. The light steel structure uses very light color steel tiles as the roof, which is also very large span, suitable for large-scale laying of photovoltaic modules. The colored steel shingles are made of a thin layer of metal-clad foam, which cannot be fixed to the photovoltaic module's support by traditional methods. Special "clamps" are required, the use of which will not damage the original structure, nor cause roof leakage or damage to the overall structure. According to different color steel tile type, can choose the corresponding clamps or support foundation. For angular and vertical locking type color steel tile, can directly use clamps as the basis of solar array, doesn’t affect its integrity, so these two forms of workshop roof is very suitable for roof distributed photovoltaic power station, and trapezoidal color steel tile roof because of the installation of solar array bracket will destroy the integrity of color steel tile, so there is a potential water leakage, Waterproof measures should be taken after installation in this way. The installation of photovoltaic modules on color steel tile are based on clamps, clamp is not heavy, therefore the requirements for roof bearing capacity are not high . Given the carrying capacity, if the PV modules are installed at the optimal Angle, multiple supports are necessary to increase the weight of the roof. In terms of safety, according to the optimal tilt Angle of the solar module array, the solar module array can’t be parallel to the roof, and extra wind pressure will be generated when the wind is strong which resulting in safety risks. To sum up, solar modules can only be tiled on the color steel tile roof, so the number of photovoltaic modules installed on the color steel tile roof is related to the area and bearing capacity of the roof.
