Why is your home solar PV system not going to be used for 25 years?

- Jan 26, 2019-

Today, with the promotion of comprehensive resource conservation and recycling, photovoltaic power generation is already well known to us, and many people have installed photovoltaic power plants. As we all know, the operating cycle of a photovoltaic power station can reach 25 years, but according to relevant information, a large number of people installed power stations have not reached the "legend" for 25 years. Why is this? Today, I will give you details introducing your PV power plant for less than 25 years.


It is understood that there are three reasons:


The first reason: the hardware equipment of the new energy photovoltaic power station

A photovoltaic power station is constantly running every day, and the equipment itself has a certain loss. The biggest damage to these losses is the hardware support of the PV modules, inverters and brackets.

Let's talk about photovoltaic components. PV power plants can be used for 25 years mainly based on the life of crystalline silicon components. The quality of crystalline silicon component products can still have 80% of factory efficiency after 25 years of use. .

Followed by the bracket: the brackets of the existing power stations are generally galvanized C-shaped steel or aluminum alloy, and the life of these two materials is far more than 25 years. Therefore, as long as a qualified stent product is selected, there is no need to worry about the life of the stent.

Finally, the inverter, because it is mainly composed of electronic devices, the life of the device is also very long, so the quality of the selected inverter products is qualified, and prolonging the service life is not a problem.

Therefore, in order to extend the life of the power station, the hardware must select a reliable product.


The second reason: software equipment for new energy photovoltaic power plants

The household photovoltaic power station is composed of components, inverters, distribution boxes and other equipment. The equipment comes from different manufacturers. Once the equipment fails, it is not conducive to troubleshooting. The traditional manual inspection method is time-consuming and laborious, and the efficiency is low.

Therefore, some leading domestic PV power station service providers have developed photovoltaic monitoring systems, which have no dead angle scanning monitoring in all directions, can monitor the photovoltaic power generation situation anytime and anywhere, greatly improve the overall operation and maintenance service of the power station, and can delay the aging rate of the power station.

Therefore, in addition to choosing a reliable product, and want to extend the life of the power station, you need to start with the software and choose a service provider that can provide monitoring and background.


The third reason: daily maintenance of new energy photovoltaic power station

A photovoltaic power station is like a human body. The body is strong, and you should pay attention to maintenance. To ensure optimal performance of your components, the following maintenance measures are recommended:

1. Install anti-rain cover for outdoor electrical equipment such as inverters and distribution boxes, and clean and inspect the equipment frequently. This can reduce wind and rain erosion and extend equipment life.

2. Scrub PV modules frequently and check them regularly. Focus on the following points:

1 Whether the component glass is damaged;

2 Whether there is a sharp object touching the surface of the component;

3 Whether the component is blocked by obstacles or foreign objects;


Why your PV power plant can not be used for 25 years? After detailed introduction above, you can conduct a detailed investigation of these existing problems. If there are problems, you can correct and solve them in time. More about photovoltaic power generation question, please feel free to contact us.
