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.

In recent years, with the decline in photovoltaic subsidies in various countries and the decline in investment income of pure photovoltaic projects, solar power storage system have become the choice of more and more people. According to different applications, solar power storage system can be divided into off-grid power storage systems, on-grid power storage system and hybrid power storage systems. The power storage system is composed of photovoltaic array,  inverter, battery pack, load, power grid, etc. When there is sunshine, the photovoltaic array converts solar energy into electric energy. Then supplies power to the load and charge the battery pack through the inverter. When there is no sunshine, the battery and the grid supply power to the AC load. Working mode of Corigy power storage system: 1. Generate electricity for your own use mode. Suitable for areas with low subsidies and high electricity prices. When there is sun during the day, the energy from the solar panels is supplied to the load first, and the excess energy is first supplied to the battery for charging, and then sold to the grid. When the solar panel is not generating power at night, the battery is discharged to the load first, and when the stored electricity of the battery is used up, the grid will supply power to the load. 2. Time mode: It is suitable for areas with a large difference in electricity prices between peaks and valleys. By setting the charging and discharging period of the battery, peak shaving and valley filling can be carried out to earn the peak and valley electricity price difference. The larger the price difference, the higher the corresponding income. When the electricity price is cheap, the load uses the electricity from the grid and at the same time stores the electricity generated by the solar panels. During periods of high electricity prices, the load uses battery power first. 3. Standby power supply mode: suitable for areas with frequent power outages. When the power grid is out of power, it can be used as a backup power supply. In this mode, when the grid is connected, the battery will always be in a charged state and will not be discharged. When the grid is out of power, the battery will be discharged for use by the load. When the power grid is restored, it will be automatically connected to the grid. 4. Off-grid mode: suitable for areas without grid access. In areas where there is no grid connection, the solar panel supplies power to the load during the day, the excess electricity is stored in the battery, and the battery discharges to supply power to the load at night.

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.

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/㎡.
