Photovoltaic industry is a sunrise industry based on semiconductor technology and new energy demand, and the high ground of the future global advanced industry competition. PV mounting system is one of the critical component of photovoltaic power station. As the support system of solar modules, it is a reliable guarantee to maximize the utilization of photovoltaic energy. According to the different materials, mounting structures usually divided into: Ordinary steel structures and new aluminum alloy structures. The mounting structures exported by Kseng every year are mainly in aluminum alloy. The advantages of aluminum alloy solar mounting structure includes: ①.Anti natural corrosion: Aluminum placed in the air forms a dense protective layer of aluminum oxide on top, which prevents further oxidation. ②.Anti galvanic corrosion: When the steel bracket and solar panel in contact, aluminum panel frame is prone to galvanic corrosion, while the aluminum bracket avoids this phenomenon. ③.Keep voltage balance: The excellent electrical conductivity of aluminum, can better conduct the weak current generated by various reasons in the PV mounting system. ④.Easy forming: Aluminum products with different section shapes can be easily obtained by extrusion process with different dies. ⑤.Easy machining: Aluminum profiles can be easily sawed, drilled, punched and folded to the required specifications, and the energy consumption of the process is much lower than that of steel. ⑥.Low temperature resistant: Ordinary steel, especially the welding area, is fragile and brittle in low temperature, while the strength of aluminum alloy material increases.

For the “carbon peaking and carbon neutrality goals”, Kseng has formed a complete product line in PV mounting system after years of efforts , from fixed system, to fixed-adjustable system, and then to tracking system. So let's talk about the Kseng fixed-adjustable series. After years of updating and iterating, Kseng KSM fixed-adjustable mounting system upgrade to newest KSM-SA and KSM-MA fixed-adjustable system in 2021. Compared to the traditional fixed system, KSM series with more reasonable structure, better cost, higher adjustable precision and generating efficiency, wind resistance performance is more stable as well. The main structure of Kseng KSM series with large size section in the industry, increase system frequency and damping ratio, which effectively reduce the amplitude and deflection, and greatly improve the wind resistance. Adjustment mode can be selected as "stepless adjustment" and "step adjustment" according to customer's requirement. High adjustment precision, high operation and maintenance efficiency, easy for one-person adjustment. KSM fixed-adjustable system has strong terrain adaptability and flexible arrangement. The east and west can adapt to 20% slope, make full use of irregular land and improve land utilization rate. The north and south slope is unlimited, and various of component layout schemes can be adopted. KSM fixed-adjustable system adopts maintenance-free adjustable mechanism, select international first-class brand bearings, self-lubrication, UV resistance, service life of up to 25 years.

Distributed photovoltaic power stations are generally built on the residential roof, industrial roof and vegetable greenhouses to make full use of space. Centralized photovoltaic power stations to make full use of abandoned land resources, mostly built in desert and Gobi areas . Similarities between distributed PV power stations and centralized PV power stations: ① Same principle, use solar energy to convert into electricity, and then connect the generated electricity to the grid for production and domestic use. ② Same modules, It is common to use monocrystalline silicon panels or solar films. ③ Use same equipment, which includes inverters, transformer, combiner box etc...... The function of the inverter is to convert the generated direct current into alternating current. The role of the transformer is to convert the inverter to AC voltage boost. The function of combiner box is to gather the DC power of the solar panels and transfer if to the inverter uniformly. Differences between distributed PV power stations and centralized PV power stations: Ⅰ.Different installation site: Distributed photovoltaic power stations are mostly installed on roofs and agricultural greenhouses, mainly in the personnel concentration of north and south China. Centralized photovoltaic power stations are mostly built in desert and Gobi areas, mainly installed on relatively remote and desolate, where the land is relatively cheap. Ⅱ.Different secondary equipment: Distributed photovoltaic power stations are used less primary and secondary equipment because the low voltage grid connection. Inverters are generally wall mounted, It’s easy to install and small in size, transformer are small size as well. Common use of power quality monitoring, anti-island protection devices, etc., equipment requirements and technical parameters are also different according to different regions . Ⅲ.Different transport distance: Distributed photovoltaic is connected to the local grid, there’s little or no loss of line. Replenishment of local power supply for use by local and nearby users. As the higher voltage level, Centralized photovoltaic power station usually has its own substation. Inverters with large size are usually installed in the sub-station room. The booster function is completed by the box transformer. There are more equipment in the booster station. The primary equipment includes station transformer, switch cabinet, various transformers, arc suppression coil, main transformer and so on. The secondary equipment includes microcomputer protection, watt-hour meter, dispatching data screen and so on. Dispatching directly implements centralized management of the power station. At the same time, the station also needs a power control system etc., which is much more complicated.

Photovoltaic power generation system is a power generation system that uses solar cells to convert solar energy directly into electric energy. Its main components are photovoltaic modules and inverters. Its characteristics are high reliability, long service life, no environmental pollution, independent power grid operation. It is favored by enterprises of various countries and has broad prospects for development. The solar photovoltaic carport mainly includes photovoltaic modules with carport roof,, which can not only meet the parking needs, but also power the grid through photovoltaic power generation, increase income, energy saving and environmental protection. Photovoltaic carport is mainly composed of bracket system, battery module array, lighting and control inverter system, charging device system and lightning protection grounding system. The system mainly includes a support post fixed between support post, a tilt beam connected to a tilt beam that supporting a solar cell module array, and a fastener fixing a solar cell module array, etc. Photovoltaic carport brackets has a variety of types, conventional can be divided into single post unidirectional,double post unidirectional , single post bidirectional type. Photovoltaic carport types are divided into double parking carport, multi-parking carport, most are modular design, can be used alone, can also be used in a variety of ways, easy to expand, from a few parking Spaces to hundreds of parking Spaces, strong flexibility. If ordinary photovoltaic modules are used, the overall cost is lower. Large installed capacity, high rate of return, short payback period. The simplest way to combine photovoltaic with architecture has become more and more popular in recent years. Photovoltaic shed good heat absorption, easy installation, low cost, not only make full use of the original site, but also provide green energy. The construction of photovoltaic carport in factory parks, business districts, hospitals and schools can solve the problem of high temperature inside outdoor parking lots in summer. By installing a system of photovoltaic modules on a sunny roof, the solar energy can be converted into electricity, which can be used to supply residential electricity or industrial electricity in factories. Rooftop power generation is different from traditional centralized ground-based photovoltaic power generation. It has the characteristics of miniaturization, dispersion, economy, high efficiency and reliability. Distributed photovoltaic power stations can be installed in sunny places, such as industrial plants, residential roofs, balconies, sun rooms, ground. Combining PV modules with the roof of the carport can save costs compared to installing PV modules on the roof of the carport. It can realize all the functions of the traditional carport, and can generate electricity to bring benefits to the owner. The universal steel structure bracket is simple, generous, fashionable and beautiful. It is a clean and...
