With the popularity of distributed photovoltaic, more and more families are choosing to install photovoltaic power stations. But then there will also be some maintenance problems: how to clean the photovoltaic panels? How often do you wash it for once? Listen to so many people say that the board is fragile and easy to crack, what tools to clean the best?
First of all, we should understand, is it necessary to clean the electric plate? Many people have this question, think that they do not clean for a month or two, the power generation has not fallen much. This idea is one-sided, the research results show that: often cleaned photovoltaic panels, the power generation in the western region increased by 3% -7%, and 3% -5% in the eastern region.
The income of photovoltaic power station is a process of accumulating over a long period of time and a little makes a lot, while the number of panels loaded by the household power station itself is not much, and the cleaning and maintenance costs are relatively low. After regular cleaning and maintenance components, the improvement in power generation is bound to be significant.
How to do the cleaning work of photovoltaic panels correctly and efficiently?
Observations are important
Whether the electric plate needs to be cleaned, you can observe at a glance. If there is only dust, simply rinse or scrub; if there is obvious shelter such as leaves , more timely and meticulous treatment is needed to avoid damage to the “hot spot effect”.
The choice of tools
In addition to the automatic sprinkler system, the home distributed photovoltaic power station is basically manual cleaning. Then the choice of cleaning tools is very important, high-pressure water gun, clean soft brush or cotton mop, dishwashing liquid or soap, clean gauze. These tools themselves are cheaper, and can greatly improve the cleaning efficiency and save time.
Cleaning steps
Only a small amount of dust, only with a high-pressure water gun for simple washing or brushing can be;In the case of sand, mud and other particles, then scrub to avoid the leaves and floating ash on the plates; cleaned with soft brush, and oily objects, cleaned with clean gauze and combined with detergent and soapy water for cleaning.
matters need attention
Ground power stations and rooftop power stations with sufficient space are very convenient to clean up. However, in the flat roof and tile roof surface with no movable space, the high-pressure water gun plays a very important role in the cleaning, efficient and safe. However, in the process of using high-pressure water gun, we should pay attention to the pressure of high-pressure water gun. Excessive water pressure may cause damage to the panel, and there is a risk of hidden crack.
(1) The best cleaning time is to choose in the morning, evening or night, avoid the high temperature period such as noon, so as not to damage the components, especially the electric plate;
(2) cleaning should pay attention to the protection of their own safety, pay attention to sharp components and leakage risks;
(3) It is strictly prohibited to clean in strong wind, heavy rain and snow days, which is easy to cause dirt accumulation;
(4) It is strictly prohibited to use hard objects and sharp objects to directly contact the photovoltaic panels. Before cleaning with soft brush and gauze, it should check whether they are clean to avoid scratching the power panels;
(5) It is strictly prohibited to step on photovoltaic panels, supports and other modules, This behavior is easy to damage the modules, the gain is not worth the loss.
According to the results of the study, combined with the local rainfall situation, the cleaning cycle in November, December and January is generally once a month, and the rest of the months is usually twice a month. And in some windy, gray areas, they need to increase the frequency according to the situation. The income of photovoltaic power station is closely related to the intention of maintenance. The high frequency cleaning of household power station will undoubtedly cause too much burden to the installer.
Therefore, according to local conditions, more observation is to let oneself save worry and effort improve the income of the only choice.In order to solve the cleaning problem, the Multifit company recently developed a product solar energy cleaning brush, the product is suitable for a variety of scenes, solar panel cleaning, high-rise exterior walls, billboards, etc., brush head Angle and telescopic rod can be adjusted by themselves, nylon material is soft and durable. Automatic water washing function can effectively remove dirt, dust and other attachments. At the same time, the high speed motor can make cleaning easier. When the brush head rotates, the water will automatically flow out and can be used.
Multifit, a national high-tech enterprise committed to the research and development, production and sales of solar power generation as well as green energy and photovoltaic power station construction services, you deserve to believe! All enjoy the sun, can benefit all!
