Along with more and more extensive application in solar PV power generation technology, PV market has attracted many enterprises’ attention. However, how to choose the best suitable PV mounting structure based on the local conditions is the key point to ensure the efficient operation of the whole system. This article will analyses different PV mounting structures for different ground conditions.
Notices for Material Requirement of PV Mounting Structure
The mounting system’s structure should be easy to installation and durable. Besides, the structure’s material used for PV arrays must have excellent environment adaptability on site. Its standard corrosion resistance life should be up to 25 years. Therefore, electroplating aluminum profiles, electroplating steel and stainless steel are the commonly used materials.
Several Different Ground PV Mounting Structure Base
Ground PV Mounting Structure Base
The depth of foundation can be shallow, but large for the amount of the excavation volume, filling volume and concrete volume.
This foundation is applicable for flat area with poor bearing capacity and low groundwater.
Precast Pile Base
Precast pile has various types including the timber pile, concrete square pile, prestressed concrete cannular pile and steel pile, etc. It can be piled into the soil by pile driving equipment. And the prestressed concrete cannular as well as steel pile are main types in China construction field.
Mass construction and fast installation; without any filling or digging, it only requires to flatten the field. But it's easy to broke during piling, so steel mesh is needed to reinforce the top of the pile. This will increase project cost and its verticality can’t be guaranteed.
Used extensively for mucky soil, clayey soil, collapsible loess and filling-up soil.
Pile C-style steel, H-style steel and other-style steel pile into ground by pile driver. This installation way is easy but poor on pull-out performance.
Fast installation and good adaptability;
Not affected by season or temperature;
Convenient to pull out without influence on installation field.
Piling is difficult in hard soil and easy to damage the galvanization layer in area with many break stones. Besides, it has poor corrosion resistance in saline-alkali area.
Since 1880s, it has been widely used in the United States, Australia and Europe as an alternative with unique advantages to replace other piles, which can meet engineering requirements such as compression resistance, pull-out resistance and horizontal resistance force, etc.
It is a kind of pile with metal or non-metal helical blade, which can be screwed into the ground with professional facility. Load can be connected on the top of it. Furthermore, many advantages make it performance well such as fast installation, short project period, friendly to the environment, no damage to the vegetation. It can be used in various winter climate in northern area and easy to transfer or recycle, etc.
Suitable for Gobi Desert, prairies, desert, mudflat, etc
