Africa is a concentrated growth area of off-grid power storage system, and it is expected that the African off-grid power storage system market will usher in vigorous development in the next five years. In fact, the African PV market is naturally attractive. The region is rich in solar energy resources, 3/4 of the land can receive vertical sunlight. The availability of solar power generation is very high and the potential is huge. It is understood that the current level of electricity development in Africa is low. According to data, the electricity consumption per capita is only 200 kWh. And many countries are even lower than 100 kWh. About 600 million people are still without electricity. Large-scale photovoltaic ground-based power stations can supplement the insufficient power supply of the local grid, and off-grid power storage system can break the shackles of no power facilities and support local basic domestic electricity. In addition, off-grid power storage system can also serve small and medium-sized enterprises. In fact, the development of renewable energy is becoming a trend in Africa. The photovoltaic market is most promising in northern Africa and southern Africa. Many countries have introduced relevant policies to encourage the development of clean energy. For example, Egypt and Kenya focus on the development of new energy industries and encourage investment in public-private partnerships; foreign companies are encouraged to invest in photovoltaic energy fields; the Nigerian government is currently committed to promoting the privatization reform of power companies, which is very attractive in terms of investment incentives. Kenya, Tanzania and Ethiopia together account for more than 60% of the off-grid photovoltaic market share in sub-Saharan Africa. Among them, more than 30% of Kenya's population use off-grid photovoltaic products. In 2022, Corigy has provided more than 3MW of off-grid systems for many countries on the African continent, such as Sierra Leone, Ghana, Congo, Nigeria, Kenya, etc. In 2021, we seek to partner with more and more companies to provide our off-grid system on the African continent.

According to relevant statistics, in a large-scale solar power station project, the construction and installation cost accounts for about 21% of the total investment of the photovoltaic project, while the investment of the solar mounting systems only accounts for about 3% of the total cost. Therefore, relative to the high investment of other parts of the solar power station, the fluctuation of the cost of the solar mounting systems is not a sensitive factor. The cost of choosing a high-end solar mounting systems is only increased by less than 1%. However, if the selected solar panel mounting brackets is not suitable, the maintenance cost in the later period will be greatly increased. The overall consideration is not cost-effective. In the long term, improving the performance and quality of the solar panel mounting brackets can make the system operate safely and reliably for 25 years. This is very necessary and correct to ensure the maximization of investment benefits. Solar panel mounting structure is not without technical content, blindly pursuing low prices, in fact, is an unwise way to reduce the revenue of power stations. The steel used in a high quality steel ground solar structure should have the following properties 1. Tensile strength and yield point. The high yield point can reduce the cross-section of steel components, reduce the weight of the structure and save steel, thus reduce the overall project cost. The high tensile strength can increase the overall safety of the structure and improve the reliability of the structure. 2. Plasticity, toughness and fatigue resistance. The better plasticity can cause a larger deformation of the structure before failure, so that people can find out and take remedial measures in time. Better toughness can make the solar mounting brackets absorb more energy when it is destroyed under external impact load. Especially for power station in desert and rooftop where wind speed is high and the wind vibration effect is obvious, the toughness of steel can effectively reduce the degree of danger. Better fatigue resistance can also make the structure have a strong ability to resist alternating and repeated wind loads. 3. Processing performance. Good processing properties include cold work-ability, hot work-ability and weld-ability. The steel used in solar mounting brackets not only needs to be easily processed, but also requires that these structures and components do not cause excessive adverse effects of strength, plasticity, toughness and fatigue resistance due to processing. 4. Service life. Since the design service life of solar mounting brackets is more than 20 years, good corrosion resistance is also an important indicator to measure the quality of the solar PV mounting structure. If the solar PV mounting structure life is short, it will inevitably affect the stability of the entire system, leading to a prolonged payback period and reducing the economic benefits of the entire project.

Under the influence of inclement weather, solar panel mounting system in some areas suffered different degrees of damage. Some solar panel brackets are damaged due to design or quality problems during construction. And some solar panel brackets are damaged because of not take adequate protection measures.How to reduce the impact of flood on solar panel mounting system. 1.Before construction: first of all, select the installation site carefully. Fully examine factors such as topographical conditions, hidden dangers of geological disasters, sunshine resources, hydrological conditions, transportation conditions and power transmission conditions, etc. These factors will directly affect the installation height of solar ground mount structures. At the same time, choose the rust prevention materials of the solar ground mount structures and design it stability. For rust prevention material, Corigy provide hot-dip galvanized steel, Zn-Al-Mg coating steel and Al6005-T5 aluminum which all have a good anti-rust performance. 2.During construction: Design and construct the solar mounting brackets according to the hydrological conditions. Raise the foundation or heighten the support appropriately. Corigy can provide free design service with suitable height to customer. Solar panel mounting systems should also pay attention to drainage to prevent damage to the photovoltaic power stations due to rainwater soaking. 3. During operation and maintenance: Pay attention to the weather conditions in time. Add temporary drainage facilities before the arrival of heavy rainfall. Also, strengthen management and inspections and deal with it in time if abnormal equipment is found. CORIGY SOLAR more efficient and flexible solar mounting solutions waiting for you here!CONTACT US!

In winter, solar mounting brackets can accumulate snow easily. And the loss of power cause by snow accumulation exceeds 5%. Cleaning the photovoltaic modules in time can avoid the hot spot effect and prolong the service life of the modules. In many cases, the reflection of snow will slightly promote photovoltaic power generation. If the snow does not cover the panel module, the snow on the ground will emit sunlight back like a mirror, and the power generation will increase. However, if the snow completely covers the modules, only a small part of the sunlight passes through the snow and hits the photovoltaic modules, which will affect the photovoltaic power generation. How to install the solar panel mounting structures to reduce snow accumulation on the solar panel? 1. To install the solar racking system with a large angle. For areas that often snow, the inclination angle of the solar racking system can be larger, so that the snow will fall and reducing the accumulation speed of snow. This can reduce the speed of snow accumulation and eliminate the trouble of cleaning snow from time to time. 2. To keep a small distance from the ground to the panel during installation. Snow will not accumulate on the bottom of the panel and cover the entire panels. 3. Small photovoltaic power plants can also be covered with cloth or plastic bags when it snows, and they can be uncovered when the snow stops. 4. If it is a tiled roof, you need to pay attention to the load. When the load reaches the critical value, it is very easy to cause collapse. If it is a tile roof solar mounting system, and it’s installed flatly along the slope of the roof and use clamp to install, the load is about 0.15KN/㎡.

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.
