Although the cost of solar panel mount bracket accounts for only a few percent of the total cost of the entire photovoltaic power generation system, the selection is very important. One of the main considerations is weather resistance. During the 25-year life cycle, the solar panel bracket must ensure that the structure is firm and reliable, and can withstand environmental erosion and wind and snow loads. The safety and reliability of the installation should also be considered, and the optimal use effect can be achieved with the minimum installation cost. In addition, whether it can be maintenance-free in the later stage, whether there is a reliable maintenance guarantee, and whether the bracket can be recycled after the end of its life cycle are important factors to be considered. When designing and constructing a photovoltaic power station, the choice of the type of solar panel bracket needs to be comprehensively considered according to local conditions, because after all, various types of brackets have their own advantages and disadvantages. 1. Appearance are different The U-shapedsolar panel mount bracket is a steel with a cross section like the English letter "U", so there is no curling from the appearance. The C-shaped solar panel mount bracket has a curled edge in appearance, and its production is automatically processed by a C-shaped steel forming machine. 2. Performance are different The U-shaped solar panel bracket can bears high pressure, supports for a long time, and is easy to install and not deformed.

Excessive snow on the solar panel mounting bracket will reduce the power generation of the home power systems and ultimately affect the user's gain. To prevent snow disasters in winter, we should remember these two points. One is to install solar panels at a large angle. This can reduces the rate at which snow accumulates and saves you the hassle of cleaning it from time to time. The second is to keep a small distance from the ground when the solar panel bracket is installed. So that the snow will not accumulate on the bottom when it slides down and cover the entire solar module. The right way to clear snow from solar energy system If there is heavy snow on the module after snow, it needs to be cleaned. You can use soft objects to push the snow down, and be careful not to scratch the glass. The solar modules have a certain load-bearing capacity, but you cannot step on the solar module for cleaning, which will cause the solar module to crack or be damaged, which will affect the life of the solar module. It is generally recommended not to wait until the snow is too thick before cleaning, to prevent the solar module from freezing. In many cases, the reflection of snow contributes a small amount to photovoltaic power generation. If snow doesn't cover the modules, the snow on the ground acts like a mirror to send sunlight back, so that power generation increases. However, if the snow cover completely covers the modules, and only a small part of the sunlight passes through the snow and irradiates the PV modules, it will affect the photovoltaic power generation. Snow removal must be clean, do not underestimate the snow strips. If there is only a small piece of snow on the solar panel, it should be cleaned up. The blocked solar panel will fail as a whole, resulting in a significant reduction in the power generation and efficiency of the inverter. In addition to the above snow prevention measures, the height of the solar power station can be increased during construction, such as adding a concrete column at the bottom.

In the design of solar mounting bracket, there are two design schemes for the placement of photovoltaic modules. 1. Vertical installation, as shown in the figure below Photovoltaic panels are easy to install vertically. And also the investment is less. However, the loss of power generation caused by the shading on vertical installation and is large. 2. Horizontal installation, as shown below. The advantage of horizontal installation is that the blocked module can still ensure the output of the system. But the installation speed is slow and will increasing the bracket investment. At the same time, the amount of dust accumulated in the horizontal installation is large. It is easy to accumulate near the lower edge of the module. Corigy can provide both design to customer according to their need. Welcome to contact us. CORIGY SOLAR more professional and flexible solar mounting solutions waiting for you here! CONTACT US!

The solar off-grid system is used in remote places far away from the public power grid. It has a wide range of uses, from residential electricity, traffic lights, to communications, emergency power supplies, etc., solving the problem of inability to supply power in remote areas. Small off grid solar system are mainly used for residential electricity consumption, and generally consist of a set of several solar module. How to build a small off grid solar system 1. Lightweight materials: Off-grid systems often take a long time to transport before reaching the user. In order to facilitate transportation, weight reduction is the first condition. Therefore, aluminum brackets have significant advantages in off-grid systems. Corigy’s mounting structure adopt Al6005-T5 aluminum which is lightweight and easy for transport. 2. Frugal use of materials. 3. Easy to install. The variety and number of installation tools must be minimized. In some areas, such as Tibet, China, herdsmen need to move frequently, and the brackets are as easy to load and unload as possible. 4. Adapt to local conditions: The installation site of each off-grid system project places different requirements on the brackets. So before engineer designing, we will do a research on your project. After that Corigy’s professional engineer team can fully consider the geographical environment and the needs of users when designing brackets.

1. Equipment The main equipment affecting power generation in solar energy system includes solar cell modules, combiner boxes, inverters and grid-connected infrastructure. In the process of selecting modules for power station construction, it is necessary to continuously optimize and match, mix A-class and B-class solar cells, and consider the quality of the modules at the same time. It is necessary to fully consider the influence of actual operating conditions such as latitude, spectrum, temperature, shading, location, wiring, etc. on the output of photovoltaic cells. The inverter is the only device in the solar energy system that can increase power generation except for solar modules. And it is expected to increase the power generation efficiency by up to 10%. So choose the high quantity inverter is important. 2. Optimized design The goal of system optimization is to make the amount of electricity generated by the solar energy system maximum mainly by checking the actual installation of sunlight intensity, light reflectance, external ambient temperature, etc. When designing the system, factors such as the shadow of the system, the installation orientation and the system configuration need to be considered. Among them, the shadow of the photovoltaic system will affect the efficiency of the system, and produce a heat pulse effect, shortening the life of the solar modules. 3. Engineering Quality The project party needs to avoid the phenomenon of delaying the construction period. It is necessary to select suitable and qualified auxiliary materials to ensure the quality of the project and avoid unnecessary power generation losses. Regular maintenance and supervision are carried out to ensure the normal operation of photovoltaic power plants. Corigy’s high quality solar energy system choose high class solar module and inverter. And professional engineer team will help you deign the most suitable design for free, which will reduce your worries.

As we all know, the light receiving surface is maximized when the plane of the object is perfectly perpendicular to the light. If the object is tilted, the plane of the object and the light will have an angle, and the power received will be relatively reduced. Therefore, when designing solar ground mounting structure, we should try to make the angle of the solar panel mounting structure perpendicular to the sun, so as to obtain the best power generation. But in the south, the mounting structure for solar panels is installed at a low angle. The higher the latitude, the greater the angle of installation. Why not install it flat to get the best power generation? Because the diameter of the sun is 109 times the diameter of the earth. Therefore, it can be considered that the sunlight on the earth is direct. But the earth is not a plane, but a huge sphere. Close to the equator, it can be considered that the sun is directly shining, so the solar modules can be installed horizontally. In high latitudes, the sun is not in the center at noon, as people see it, but has a certain angle. The higher the latitude, the greater the angle. In order to obtain the best power generation, the mounting structure for solar panels is designed with a tilt angle. The most ideal tilt angle is to make the solar cell's annual power generation as large as possible. If you don't know how to choose the best angle, you only need to provide the latitude and longitude of the project location, and Corigy's engineer can use the software to calculate the best inclination angle of the solar mounting structure.
