If metal corrosion occurs on the solar panel support, the strength of the panel itself and the joints will be reduced, and it may be damaged by strong winds and earthquakes. Therefore, the corrosion of the solar panel racking system can not be ignored in extending the life of the photovoltaic power station. The main corrosion-prone parts of solar mounting brackets are 1. Metal surface and end surface produced after cutting 2. The root of the solar panel brackets where connected to the ground or concrete foundation 3. Joint with solar panel Metal surface and end surface produced after cutting The rack made of steel usually requires hot-dip galvanizing or other processing on the surface. However, despite the anti-corrosion plating treatment has done, the rack will gradually corrode slightly. Depending on the installation environment, the degree of corrosion is also different. And iron materials are corroded at most about 0.1 mm per year. But the galvanized steel is only about one-tenth of it. In addition, the degree of corrosion varies greatly depending on the type of plating. Corrosion may also occur in the processed metal parts. For example, in the process of manufacturing the bracket, the metal sheet need to be cut and will form the end surface. This end surface exposes the steel material that has not been electroplated, and it may be prone to corrosion depending on the steel material and the thickness of the plating. Corigy's surface treatment of solar panel fixing brackets can be done from hot-dip galvanizing to Al-Mg-Zn coating. And the film thickness>80um. Surface treatment is carried out after cutting. And the rubber end cap can be provided too. The root of the solar panel brackets where connected to the ground or concrete foundation The part where connected to the ground or concrete foundation is prone to corrosion. This is caused by the high humidity of the ground and the concrete surface exposed to rain. The metal has been soaked for a long time and corroded. Effective drainage measures must be taken around the bracket. The upper part of the concrete foundation can adopts inclined design, etc. Joint with solar panel If different metals are in contact, due to the difference in the standard electrode potential, a current will be generated. The metal with a strong ionization tendency will be severely corroded. So avoid using different metals on the joint part of the structure. Regular inspection of the bracket, re-painting of the surface film and replacement of corroded parts according to the specific situation, etc., will help to extend the life of the solar power system.

The design and selection of solar panel mounting brackets in coastal areas must first consider the impact of typhoons. At the same time, it is also necessary to consider other natural factors such as humidity, severe salinization and corrosion, and high temperatures in the coastal areas. To resist the damage of typhoons The situation shown in the picture above can be inferred that the foundation of the mounting structure is too small. And the foundation is not effectively connected to the roof. Also, the height of the solar panel mounting systems is too high. The height of the two vertically placed modules is more than 4 meters, so the back side of the solar mounting brackets will subjected to a large wind pressure and easy to blow over. To resist the damage of typhoons, first of all, a very strong solar panel fixing brackets is required. The general materials of solar panel racking system are aluminum alloy and carbon steel. Corigy can provide both type of those materials with different surface treatment. Theoretically, the maximum wind resistance of the solar mounting system solutions designed by Corigy can reach 216 km/h. If it is installed on the roof, the foundation must be firm. The counterweight is generally a cement foundation. The cement foundation must fully consider the load of the building. At the same time, it must meet the requirements of wind load and snow load. Corigy's engineers team can help customers calculate the appropriate counterweight to avoid customers’ worries. To resist the damage of moisture and salinization Q235B steel or Aluminum Alloy materials have excellent corrosion resistance. For brackets in coastal areas we even use Q345B material. In addition to the material, the thickness of the material and the thickness of the galvanized layer are also very important. Under normal circumstances, the thickness of the structure should not be less than 2.5 mm, the thickness of the galvanized layer should not be less than 65 microns. And the surface of the zinc layer should be evently, free of burrs, overburn, ash and scars and other defects. There must be no zinc tumors that affect the installation. The zinc layer of the thread should be smooth, and the bolt connection should be able to be screwed in. In addition, our new material, Al-Zn-Mg coating steel is becoming more and more popular as solar panel mounting structure in coastal areas. To resist the damage of high temperatures The temperature in coastal areas is generally higher, and the temperature has a great influence on photovoltaic modules。 Install the bracket a little higher, so that the bracket has a little bit away from the roof. So as to ensure ventilation and increase power generation. The installation location of the photovoltaic power station is also important. And it is necessary to consider the installation location, installation orientation, installation angle, load requirements, and arrangement and spacing.

Tip1: Which type of solar panel roof mounting brackets to choose Installation methods of photovoltaic modules are different for different roof type, common installation methods include attached type, ballast type and pile foundation type. Attached type is the best choose for Caigang tiles roof. Laying the modules on the roof directly has the best windproof effect and more safety. In addition, the tile roof also has a certain inclination. Although it may not be the best inclination corresponding to photovoltaic power generation, but the transformation cost caused by increasing the inclination also needs to be considered comprehensively. For cement roofs, the common installation methods are ballast type and concrete foundation pile type. In many cases, building owners are not allowed to drill holes on the concrete flat roof. On the one hand, they are worried about the strength of the old building, on the other hand, they don’t want to change the waterproof performance of the roof. This is the reason for choosing ballast type or concrete foundation installation. Since the ballast type is not anchored to the roof, a windshield can be considered to be added on the side. The main purpose of the concrete foundation is to ensure that the flat roof solar racking remains intact even during stormy seasons. It ensures a good installation without causing roof leaks, and can also improve the efficiency of solar cell modules Tip2: Flat roof does not mean tile installation It seems the most ideal way to install photovoltaic modules on a flat roof is using tiled methods. This method not only maximizes the installation area, but also allows the photovoltaic panel to be used as a roof top to increase the space area. But in fact, installing photovoltaics on a flat roof does not mean that you should set its inclination to 0 degrees. We need to consider many factors and should avoid tile installation. These factors include: 1. Tiled components are easy to accumulate dust, which may cause 10% or even 30% of power generation loss; 2. It is inconvenient to clean, and the ponding is not easy to flow out; 3. Compared with inclined installation, the power generation will be reduced; 4. The payback period of investment will be longer; 5. It may not be possible to remove dust accumulation by rainfall; Tip3: Flat roof solar mount must consider wind speed In the design phase of the solar mounting system, the maximum wind speed that may occur in the local area must be considered, especially in areas where the wind speed exceeds 180 kilometers per hour. Ordinary flat-roof solar power generation systems can withstand wind speeds of 160 km/h. But if wind protection is not considered between the arrays, the instantaneous wind speed caused by the airflow in a local area will far exceed the actual wind speed. Therefore, the selection of solar mounting brackets, structural design, ballast or concrete foundation strength design must rely on the recommendations of professional organizati...

Solar panel roof mounting systems is very popular. In 2020, the total installed capacity of photovoltaic roofs worldwide will reach 60GW. Installing solar roof rack system is not only a new trend, but can also bring benefits to companies and residential buildings. The principle of photovoltaic roof cooling First of all, photovoltaic modules reflect heat. The light irradiates the solar photovoltaic module, part of them are absorbs by the photovoltaic module and converts into electric energy, and the other part is reflected by the photovoltaic module. Secondly, the photovoltaic module refracts the sunlight, and the sunlight attenuates after the refraction Finally, photovoltaic modules form a shelter on the roof. High-efficiency monocrystalline silicon modules and polycrystalline silicon modules can form a sheltered area on the roof to insulate and cool the roof. According to the test of relevant professional institutions, the building with roof-mounted photovoltaic power station can lower the indoor temperature by 5-8 degrees than the building without installation. Benefits 1. Cool down the physical temperature of the plant The summer heat in the factory is unbearable, and the factory is often faced with power cuts, which seriously affects the factory's production schedule. The installation of solar photovoltaic can not only provide the power required for production to the factory, but also play a role in heat insulation and shading, and physically cool the plant. 2. Reduce enterprise energy consumption The average temperature of a roof with solar panels in summer will be 2℃-4℃ lower than that of the unpaved roof. And the energy consumption of air-conditioning can be reduced by 30%-40%. 3. Improve the working environment of employees After the plant temperature drops, it can greatly prevent workers from heatstroke, improve production efficiency, and reduce production costs.

In recent years, under the influence of extreme weather, strong winds have appeared in many places, causing great losses to solar panel racking system. How to reduce the impact of high winds on solar panel mounting brackets？ First of all, wind speed should be taken into consideration when designing photovoltaic mounting systems. The strength of the material, the angle and height of the bracket will affect the stability of the bracket. The second is the basic construction of the solar racking system. There are cement foundations and pile foundations. These two methods should be selected according to installation requirements and geological soil conditions. For details, please refer to our article https://www.corigy.com/blog/How-to-choose-suitable-grounding-screw-for-your-solar-panel-ground-mounting-systems_b23 Third, in addition to the surrounding buildings or trees covering the location of the photovoltaic power station, it is more important to consider the basic conditions of the installation site. The topography of the site should be as flat as possible. Locations with good geological structure and hydrological conditions should be selected. And as far away as possible from faults, landslides, mudslides, and areas that are prone to flooding. Finally, conduct a comprehensive inspection of the solar panel support frame to see whether the screws, fasteners and fasteners of the components are loose or damaged. If there are any, they need to be reinforced or replaced as soon as possible. CORIGY SOLAR more professional and flexible solar mounting solutions waiting for you here! CONTACT US!

The installation environment of roof photovoltaic support includes slope roof and flat roof. The solar panel roof mounts must conform to the roof environment without destroying the inherent structure and self-waterproof system. Roofing materials include glazed tiles, color steel tiles, linoleum tiles, concrete surfaces, etc. Different roof mounting brackets are adopted for different roofing materials. The roof is divided into slope and plane according to the inclination angle. Therefore, there are many solar mountings for the inclination angle of the roof photovoltaic system. For the slope roof, it is usually arranged in a flat way to conform to the roof slope, and it can also be arranged at a certain inclination angle to the roof. ; For flat roofs, there are two options: tiled and inclined at a certain angle. There are different bracket systems for different roofing materials. 1. Tile roof bracket Glazed tiles are building materials made of soft and hard materials such as alkaline earth and purple sand after being extruded and plastic pressed. The material is brittle and has poor load-bearing capacity. When installing the bracket, a specially designed main support member is generally fixed to the lower roof of the glazed tile to support the main beam and cross beam of the bracket. The supporting member such as the connecting plate is usually designed in an open pattern to achieve flexible and effective adjustment of the position of the bracket. The components and the beam are crimped with aluminum alloy pressure blocks. 2. Metal roof bracket Metal plates are steel formed by cold pressing or cold rolling of thin steel plates. The steel plate adopts organic coating thin steel plate (or color steel plate), galvanized thin steel plate, anti-corrosion thin steel plate (including asbestos asphalt layer) or other thin steel plate. Special-shaped steel plate has the advantages of light unit weight, high strength, good seismic performance, fast construction, and beautiful appearance. It is a good building material and component. Roof color tiles are usually divided into: standing seam type, bite type (angle type) type, buckle type (concealed buckle type) and fixed connection (open nail type) type. When installing the photovoltaic system on the metal roof, the shape of the metal roof and its load-bearing capacity should be fully considered to determine the fixing method of the bracket. The fixing method of the color steel plate tile bracket is mainly determined according to the shape of the metal roof. 3. Concrete roof bracket The concrete roof photovoltaic support is generally fixed at a fixed inclination angle, and it can also be laid out in a flat manner. The type of roof fixing method is mainly fixed by concrete foundation and standardized fixed connectors. The solar mount is a very important part of the photovoltaic power station. It carries the main body of the photovoltaic power station. If the design is unreasonable, an accident in a disaster clim...
