In the impression of many people, the solar panels that can be installed on the roof should be the same as the roof that is not often used. Basically, it is enough to let the cows graze and let it generate electricity. However, just like the roof is also cleaned, the solar panels need to be cleaned occasionally, so as not to hinder the benefits of power generation. In 2017, the news that the solar photovoltaic power plant located in the Yongan salt flat land was bombarded by bird droppings made people alert to the problem of maintenance and cleaning of solar panels; now there are many units in Taiwan that provide cleaning teaching or services.
However, it may be that Japan's solar panels telemarketing list are a few steps faster than Taiwan's. It is also a cleaning issue, and the two sides have some differences in their handling methods. Like other solar energy peripheral industries, there are many companies in Japan that provide solar panel cleaning services to explain cleaning issues to customers. The following is a step-by-step introduction to the cleaning methods that are " not recommended " by Japanese solar cleaning manufacturers. First of all, do not use a rag or other materials that are not suitable for glass to wipe.
The surface of the solar panel is made of high-transparency tempered glass, and wiping it with a rag will sometimes reduce its transparency. Moreover, if there is sand between the rag and the glass, it will cause scars. Harmful and unhelpful, please don't do it. Second, "cleaning" manufacturers suggest not to "only" clean with tap water, not . Because tap water contains calcium hypochlorite, which is used for sterilization, it will leave scales that ordinary people often see in bathroom bathtubs and walls . This kind of dirt is very tenacious, except that it will not fall off when it is drenched with water, and it is not easy to remove by rubbing hard.
