Types of Solar Mounting Foundation

Solar mounting refers to the structure used to install, fix and support solar photovoltaic modules. Its core function is to ensure that the photovoltaic modules are at the right angle and position to receive solar radiation to the maximum extent and improve power generation efficiency.

The main functions of Solar mountings are: fixing and supporting photovoltaic modules; adjusting the angle of photovoltaic modules; having durability and corrosion resistance; making installation and maintenance easier.

The Solar mounting foundation is a key component of the Solar mounting system, providing solid support for the Solar mounting to ensure that the photovoltaic modules can operate safely and stably under various climatic conditions. The selection of Solar mounting foundation needs to be determined based on the geological conditions, climatic conditions and engineering requirements of the installation site.

Common Solar mounting foundation types include: concrete foundation, spiral pile foundation, pile foundation, cement block foundation, and steel structure foundation.

Reinforced concrete foundation:

A foundation made of steel bars and concrete, used to fix and support Solar mountings, ensuring that solar modules can operate safely and stably under various climatic conditions. Due to the high strength and good durability of reinforced concrete foundations, they have been widely used in large-scale projects such as ground photovoltaic power stations.

The advantages of reinforced concrete independent foundations are that the force transmission path is clear and clear, the force is reliable, the application range is wide, and no special construction machinery is required for construction. This foundation form has a strong ability to resist horizontal loads.

Screw pile foundation:

It is a foundation form used to fix and support Solar mountings. By screwing spiral metal piles into the ground, it provides stable support for Solar mountings. The spiral pile foundation is favored because of its advantages such as quick installation and low impact on the environment. Its structural components mainly include: spiral pile body and connecting parts. The pile body is spiral with spiral blades at the end, which is conducive to providing adhesion and stability when screwing into the ground.

Pile foundation:

The pile foundation of the Solar mounting is a foundation form that supports and fixes the Solar mounting by driving piles into the ground. This foundation form has high bearing capacity and stability, is suitable for various geological conditions, and is widely used in large solar power stations. Its structure consists of a pile body and connecting parts. The pile body is usually made of high-strength steel and is treated with anti-corrosion (such as hot-dip galvanizing) to enhance durability. Different types of piles are selected according to geological conditions and design requirements, such as steel pipe piles, H-shaped steel piles, etc.

It is usually used in large solar power stations, areas with strong winds and complex geology.

Cement block foundation:

The cement block foundation of the Solar bracket is a common foundation form. By prefabricating or pouring cement blocks on the ground, the Solar mounting is fixed on it to provide stable support for the photovoltaic module. This foundation form is widely used because of its simple construction, low cost and wide range of applications. It consists of cement blocks and fixings. The cement blocks can be square, rectangular or other shapes according to the design requirements, and the size is determined according to the load requirements of the bracket and photovoltaic module. The fixings are composed of embedded parts and connectors.

This method is usually used in small and medium-sized solar power stations, temporary solar mounting systems and special geological occasions.

Steel structure foundation of photovoltaic support：

Steel structure foundation has become an important foundation form in the construction of solar mounting system due to its high strength, stability and durability. Reasonable design and installation of steel structure foundation can not only improve the safety and stability of solar mounting system, but also adapt to various complex geological and climatic conditions and improve the comprehensive benefits of the project. Through the treatment of foundation, anti-corrosion of steel and control of installation accuracy, steel structure foundation can provide long-term and reliable support for solar mounting system and ensure its stable operation under various environmental conditions.
