Autumn operation and maintenance of photovoltaic power stations how micro-inverters cope


 

Entering autumn, photovoltaic power plants have ushered in the best power generation season, with suitable temperatures and rising power generation. However, the falling leaves and floating dust that come with autumn have brought some "minor" hidden dangers to the operation and maintenance of photovoltaic power stations. If not handled properly, it will reduce the power generation efficiency of the power station and even have a certain impact on system safety. So, how should we do a good job in the operation and maintenance of photovoltaic power plants in autumn?

The impact of autumn on photovoltaic power plant operation and maintenance

Before understanding how to do a good job in the operation and maintenance of photovoltaic power stations in autumn, we first need to understand what impact the arrival of autumn will have on the operation and maintenance of power stations:

1. Reduce power generation efficiency

Fallen leaves and dust that come with autumn will stay on the surface of photovoltaic modules, blocking sunlight and affecting power generation efficiency. Especially in traditional photovoltaic systems, fallen leaves and dust on single modules will not only reduce the performance of the single module The power generation efficiency will also affect the power generation of the entire string of components. In addition, the accumulation of fallen leaves and dust on the surface of the module will also hinder the dissipation of heat, causing the local temperature of the module to rise, further reducing the power generation efficiency.

2. Increase security risks

Fallen leaves and dust may enter the interior of electrical equipment, such as inverters, component junction boxes, connectors, etc., corroding or damaging electrical components, which may lead to poor contact, short circuit and other faults. In addition, long-term contact between dust and components may also cause a decrease in insulation performance, increase the risk of electric shock and electrocution, and pose a threat to the safety of on-site personnel.

3. Increase the difficulty of operation and maintenance

Dust and fallen leaves in autumn will not only affect the power generation of the photovoltaic system, but also increase the possibility of system failure. Therefore, component cleaning and operation and maintenance of power stations in autumn are particularly important. Once a system failure occurs, operation and maintenance personnel may be faced with hundreds or thousands of components in the system and may need to investigate them one by one, which undoubtedly increases the difficulty of power station operation and maintenance.

Operation and maintenance methods of photovoltaic power plants in autumn

During the operation and maintenance of photovoltaic power stations, it is generally necessary to disconnect the power supply in advance to ensure personnel safety. Leaves, dust, etc. remaining on the surface of the components must be cleaned up in time; maintenance of the inverter mainly involves checking whether the wiring is firm, whether the equipment is damaged, cleaning debris and heat dissipation, etc.; when maintaining the bracket, attention needs to be paid to checking the bolts Whether the connection with the bracket is loose and whether the anti-corrosion coating on the surface of the bracket is cracked and peeled off; the maintenance of cables is mainly to prevent cable damage and aging and wiring loosening and falling off. In addition, we also need to clean up debris around the power station and its equipment and provide ventilation and heat dissipation to ensure the operational safety of the system in an all-round way.
