Types of photovoltaic installation methods

There are various ways to install photovoltaic modules to adapt to different environments and requirements. Here are several common installation methods for photovoltaic modules:

1. Roof installation

Flat installation: Photovoltaic modules are directly laid on the roof, parallel to the roof. This method can fully utilize the roof space, is simple to install, and has a low cost. However, attention should be paid to the impact on the roof's waterproof layer.

Inclined installation: A tilted bracket is set up on the roof, and the photovoltaic modules are installed on the bracket. This method can better adapt to the roof slope, maintain a certain distance between the module and the roof, which is beneficial for waterproofing and heat dissipation. However, the cost is higher and the installation is more difficult.

Independent installation: Photovoltaic modules are directly installed on the frame on the roof, with the frame parallel to the roof slope and at a certain height from the roof.

Direct installation: Photovoltaic modules are directly installed on the roof covering without additional support frames. However, attention should be paid to maintaining the sealing of the roof covering, and the working temperature of the module may be higher under this installation method, affecting the power generation efficiency.

Integrated installation: Photovoltaic modules are directly installed on the roof rafters, replacing the conventional roof covering. This method is conducive to ventilation, improving the module's working efficiency, and facilitating line inspection and maintenance. However, the cost is higher and the installation is more difficult.

2. Ground installation

Ground-mounted bracket installation: Usually used in large-scale photovoltaic power stations. Horizontal and vertical adjustments are required to achieve the best power generation effect. It can adopt beam, frame, or single-column structures. Before installation, the base should be made and the metal frame fixed to the base, and finally the photovoltaic modules are installed on the frame.

3. Pole installation

Pole installation is usually used for installation on land and water surfaces. It mainly includes concrete piles, telescopic poles, and frame-type iron frames, etc. Pole installation can meet the needs of various terrains and has high power generation efficiency.

4. Wall installation

Wall installation is a space-saving installation method for photovoltaic modules. It is suitable for walls of residential or industrial buildings, and photovoltaic modules can be installed on porches, balconies, walls, etc., to achieve the effect of photovoltaic power generation.

5. Floating installation on water surfaces

It is usually used for installation on reservoirs, oceans, and other water surfaces. Photovoltaic modules float on the water surface and can have a larger area to collect sunlight. However, attention should be paid to waterproofing and material durability issues.

6. Solar tracker installation

Solar tracker is an efficient installation method for photovoltaic modules. It can follow the trajectory of the sun to maximize the collection of sunlight. Solar trackers can be used not only in large-scale photovoltaic power stations but also in household photovoltaic systems.

7. Wind shield installation

Wind shield installation is generally used on building walls, balconies, etc. Through the shielding of the wind shield, the wind force impact on the photovoltaic modules is reduced, improving the installation quality and efficiency.

8. Ground-mounted side pole bracket installation

Ground-mounted side pole bracket installation is a low-cost photovoltaic module installation solution. The photovoltaic modules can be directly installed on the side pole bracket, suitable for various terrains.

9. Bracket installation

A simple bracket device is used to install the solar cell array. Two angle-shaped electroplated steel brackets are fixed to the exterior wall and roof of the building with screws, and another pair of brackets is connected to the end of the solar cell module frame. These two sets of brackets are connected to form a simple, durable, and inexpensive installation device. The bracket device can be made rotatable to adjust the inclination angle according to the seasons, thereby optimizing the performance of the photovoltaic system. In conclusion, there are various ways to install photovoltaic modules, and the specific choice of method should be made based on a comprehensive consideration of the actual situation.
