Components Of Photovoltaic Power Plant Projects

For example:

Solar panels: 

If the overall working environment is in the desert, you can choose dust-proof and anti-dust components, because this can reduce dust accumulation and increase power generation. If the overall working environment is at the seaside, you can choose solar modules that are more resistant to salt corrosion to reduce corrosion of solar modules in the ocean monsoon climate.

Brackets:

As the basis for supporting solar modules, brackets have strict requirements on materials. Aluminum alloy, iron, zinc-magnesium-aluminum, stainless steel, galvanized steel, and non-metallic brackets can be selected according to the on-site climate environment. Because in a working environment that lasts for decades, the durability and support of photovoltaic brackets are even more tested.

Photovoltaic cables: 

Photovoltaic cables are exposed to harsh working environments. When customizing photovoltaic cables, the following issues must be taken into consideration:

1. Outdoor environment:

Waterproof performance: In outdoor installation, photovoltaic cables need to have good waterproof performance to prevent rainwater from intruding and damaging the cables.

Weather resistance: Photovoltaic cables should have good weather resistance and be able to withstand extreme weather conditions such as ultraviolet rays, high and low temperatures.

2. High temperature environment:

Heat resistance: In high-temperature environments, photovoltaic cables need to have good heat resistance to ensure that the cables are not damaged due to overheating.

Thermal Conductivity: Given that high temperatures can affect the thermal conductivity of a cable, choosing a material with good thermal conductivity may be a consideration.

3. Low temperature environment:

Cold resistance: In cold environments, photovoltaic cables need to have good cold resistance to ensure that they can still work normally at low temperatures.

Flexibility: At low temperatures, some cables may become brittle and stiff, so it is more appropriate to choose cable materials with good flexibility.

4. Chemically corrosive environment:

Corrosion resistance: If the photovoltaic system is in a chemically corrosive environment (such as the seaside), the cables should have good corrosion resistance to avoid corrosion damage to the cables.

5. Mechanical stress environment:

Tensile Strength: In environments where mechanical stress is required, choosing cables with higher tensile strength can improve system stability.

Photovoltaic inverters: 

The following points should be considered when considering and customizing photovoltaic inverters:

1. Outdoor environment:

Protection level: In outdoor installations, the inverter should have a high level of protection against water, dust, and harsh weather conditions.

Weather resistance: It has good weather resistance and can operate stably for a long time in outdoor environment.

2. High temperature environment:

Heat dissipation performance: In high-temperature environments, the inverter should be designed with an effective heat dissipation system to ensure that it will not overheat during long-term operation.

Temperature range: Choose an inverter that can operate normally under high temperature conditions and meets the requirements of a specific temperature range.

3. Low temperature environment:

Start-up performance: In low-temperature environments, the inverter should have good start-up performance to ensure normal startup and operation at low temperatures.

Cold resistance: Choose an inverter that is suitable for low-temperature environments and has good cold resistance.

4. High altitude environment:

Adapt to high altitude: If the installation site is in a high altitude area, choose an inverter that is adapted to the high altitude environment to ensure performance and stability.

Ventilation: High-altitude areas may affect air density, and the inverter should have good ventilation performance.

5. Chemically corrosive environment:

Corrosion resistance: If the photovoltaic system is in a chemically corrosive environment, the inverter should be corrosion-resistant to avoid corrosion damage.

Electromagnetic interference environment:

6. Electromagnetic compatibility: In an environment with electromagnetic interference, the inverter should have good electromagnetic compatibility to prevent mutual interference.

Photovoltaic energy storage: 

The selection of photovoltaic power station energy storage systems involves the specific needs of different sites and environments. Here are some suggestions for different venues and environments:

1. Outdoor environment:

Level of protection: In outdoor environments, energy storage systems should have a good level of protection against water, dust, and harsh weather conditions.

4. High altitude environment:

Adaptation to high altitude: If the installation site is in a high-altitude area, choose an energy storage system adapted to the high-altitude environment to ensure performance and stability.

7. Emergency power supply requirements:

Quick response: If the energy storage system is used for emergency power supply, quick response capability is a key factor, and the system should be designed with fast charging and discharging characteristics.

8. Renewable energy integration:

Interoperability: If the energy storage system is integrated with renewable energy sources, such as wind power or other renewable energy sources, it should have the ability to work together.

Distribution boxes and grid-tied cabinets can be configured and selected based on solar panels, inverters, energy storage and other equipment.
