With the increasing development of photovoltaics today, how to choose a suitable solar photovoltaic support according to local conditions is an important link to ensure the safe and efficient operation of the entire photovoltaic system. Starting from the installation form, the existing solar photovoltaic supports can be roughly divided into two categories: ground solar photovoltaic structures; roof solar photovoltaic structures. Let's start with different application scenarios and talk about how to choose the solar PV bracket suitable for the project site.

Design and selection of solar racking and precautions during construction:

1. The installation structure of the photovoltaic array bracket should be simple, strong and durable. The materials used to manufacture and install the photovoltaic array bracket must be able to withstand the harsh environment of the project site to ensure 25 years of weathering and corrosion resistance and structural strength. Anodized aluminum, galvanized steel and stainless steel are all ideal choices.

2. During the construction of the photovoltaic array foundation and support, it is necessary to avoid damage to related buildings and ancillary facilities as much as possible. If local damage is unavoidable due to construction needs, it should be repaired in time after the completion of the construction.

3. When installing solar panels on the roof, the embedded parts of the base should be firmly welded or connected to the main structure of the roof. If welding or connection is not possible due to structural restrictions, measures should be taken to increase the attachment between the base and the roof. Focus on it and fix it with wire tensioning method or bracket extension fixing method.

4. The frame and support of the panels should be reliably connected to the grounding system.

Common ground installation fixed form

Basic form:

1. Pile driven

Measure the distance at the installation site and directly use the pile driver to drive the column into the ground, which is convenient and quick. Before installation, geological and soil testing is required to determine the appropriate penetration depth.

Advantage:

Fast speed and strong adaptability;

High cost performance;

Not subject to seasonal temperature restrictions;

It is convenient to remove the piles and does not affect the reuse of the installation site.

2. Ground screw

When the installation site is too hard or there are too many gravel, it is inconvenient to hammer the column directly into the ground, ground screw can be used. Drive the screw-in steel pipe into the ground, and then fix the column on it.

Advantage:

Strong adaptability, flexible and diverse combination;

Not subject to seasonal temperature restrictions;

It is convenient to remove the piles and does not affect the reuse of the installation site.

3. Precast cement foundation

If the installation site is not suitable for plug-in piles, you can choose to make a cement foundation. The brackets are placed on the cement foundation and fixed with bolts.

Advantage:

Good strength and high precision;

Strong adaptability to the ground.

4. Direct cement pouring

Another form of cement foundation is to directly pour the bracket and cement together. This way, compared with the above, the time for bolting is saved, but the positioning accuracy of the support column is higher when pouring.

Advantage:

Good strength and high precision;

Strong adaptability to the ground.
