Photovoltaic power station autumn operation and maintenance, see how micro inverters cope with it?

introduction

In autumn, photovoltaic power stations usher in the best power generation season, with suitable temperatures and rising power generation. However, the falling leaves and floating dust that come with autumn bring some "small" 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 the safety of the system. So, in autumn, how should we do a good job in the operation and maintenance of photovoltaic power stations?

Impact of autumn on photovoltaic power station operation and maintenance

Before we understand 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 coming of autumn will have on the operation and maintenance of power stations:

1

Reduce power generation efficiency

Fallen leaves and dust in 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 a single module will not only reduce the power generation efficiency of the single module, but also affect the power generation of the entire string of modules. 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

Increased security risks

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

3

Increased difficulty in operation and maintenance

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

Operation and maintenance methods of photovoltaic power stations in autumn

During the operation and maintenance of a photovoltaic power station, it is generally necessary to disconnect the power supply in advance to ensure the safety of personnel. The fallen leaves and dust on the surface of the components should be cleaned up in time; the maintenance of the inverter mainly involves checking whether the wiring is firm, whether the equipment is damaged, cleaning of debris and heat dissipation; for the maintenance of the bracket, it is necessary to check whether the connection between the bolts and the bracket is loose and whether the anti-corrosion coating on the surface of the bracket is cracked and falling off; and the maintenance of the cable is mainly to prevent the cable from being damaged and aging and the wiring from being loose and falling off. In addition, we also need to do a good job of cleaning up debris around the power station and its equipment and ventilating and cooling to ensure the safe operation of the system in all aspects.

APSON Microinverter Solutions

Make power station operation and maintenance more efficient and convenient

In terms of the operation and maintenance of photovoltaic power stations in autumn, APNS microinverters have powerful product performance and protection functions, which can easily cope with complex environments such as fallen leaves, dust, and rain, and effectively improve the power generation and safety of the system, including the following aspects:

1

Independent MPPT function

The APLS micro-inverter system adopts a parallel circuit design and has an independent maximum power point tracking (MPPT) function, which can optimize the output of each component near the maximum power point. Even if some components are affected by fallen leaves, dust, etc. or fail to generate electricity, other components can still generate electricity normally, which can effectively eliminate the "short board effect" and improve the overall power generation income.

2

Leading IP67 protection level

APSON micro inverters have reached the industry-leading IP67 protection level and have excellent dust and water resistance, which can prevent fallen leaves, dust, etc. from entering the interior of the product, especially on the roof of the factory, and can effectively block the smoke and dust particles brought by the chimney and exhaust fan, ensuring the normal operation of the body. At the same time, the upper and lower covers of the product are all die-cast, and sealant is injected at the joint. The interior of the body adopts a full glue filling process, which can keep it in a sealed state for a long time and ensure the reliability of components.

EMA component-level intelligent operation and maintenance

APpower Micro Inverter is equipped with a digital intelligent operation and maintenance system. Users can check the location of each component and power generation status at any time through the APpower EMA intelligent operation and maintenance platform. When a system failure occurs, we can use EMA's component-level monitoring function to clearly locate the problem component without having to check one by one, saving a lot of manpower and material resources for system operation and maintenance.

summary

Timely cleaning of autumn leaves and dust and inspection of equipment can effectively improve the power generation efficiency of the system, reduce the failure rate of the power station, and ensure the long-term effect of the photovoltaic power station. APpower Micro Inverter has independent maximum power point tracking (MPPT) function, IP67 protection level, intelligent operation and maintenance and other powerful functions, which help the power station to operate efficiently, reliably and intelligently, making the operation and maintenance of photovoltaic power stations in autumn easier and simpler.
