The cleaning work for solar panels for a long time is mostly done by the investor and very unscientific. To increase the durability and efficiency of about tens of millions of panels, a number of businesses have launched professional and expensive solar cell cleaning services.
Huynh Duc Thanh, an electrical engineer working at the Southern Power Corporation (EVNSPC), said that in the solar power system that investors are installing, solar panels (photovoltaic cells) are equipment. important and vulnerable to the influence of external factors. Vietnam is a tropical, hot, humid area with a lot of rain, objects that have a great impact on the life expectancy by wind, rain, sea water, ash … For solar panels, seawater, and rock dust. In areas where cement exploitation, production, sawdust of wood factories, chemicals in industrial zones … have a great impact on the durability and efficiency of the panels is very high.

Ho Chi Minh Meanwhile, according to engineer Thanh, the current method of cleaning the panels is mostly done by investors, most of them are using water, available facilities and using a hose to wash them, this method is not technically correct. in terms of maintenance, because many areas have water contaminated with alum, hard water, there is a lot of organic matter, more dissolved metals… leading to further damage to the panels. “The effectiveness of the project apart from equipment, materials, installation techniques, the operation and maintaining the efficiency of the system is related to the cleaning of the panels. Keeping the panels clean is the key to maximizing output, increasing economic efficiency for investors, ”Thanh said. Solar power is booming in Vietnam, especially household investment packages, concentrated in remote and island areas in the South. According to the Vietnam Electricity (EVN), by the end of 2020, the total capacity of renewable energy sources will be 17,430 MW (up 11,780 MW compared to 2019) and accounting for 25.3%. . In which, there are about 8,000 MW of rooftop solar power and more than 8,400 MW of large farm solar power. Thus, according to investors’ calculations, the whole country currently has no less than 30 million solar panels operating in the whole system and will increase when many projects are under construction and about to be operational. Seeing this potential, a number of businesses in the South have added new services, which are professional cleaning of solar panels and package maintenance for solar power systems. the investors. Mr. Le Tran Khanh Vy – General Director of Nhat Hung Environmental Technology Co., Ltd. (Thu Duc City) – said that in the face of more and more investors installing solar equipment, the company opened more professional solar battery cleaning service, currently hundreds of customers across the country have signed contracts to participate in cleaning and maintaining solar power systems with this package. To meet the needs of customers, especially solar power investment packages in industrial form, the company is forced to professionalize by producing standard cleaning solutions, investing in specialized cleaning equipment. and has a team of professional staff in charge. “The solution that the company offers is to keep batteries clean by cleaning them regularly and properly; Check the water source, if the water source is contaminated with alum, hard water, contains a lot of organic matter, lots of dissolved metals, it must be handled; choosing a cleaning solution specialized for cleaning panels, because now there are domestically produced products with appropriate and safe prices, ”said Mr. Vy. On the market, there are specialized solutions for cleaning solar cells According to electricity experts, at present, many solar power projects are invested billions of dong, even more money, but the stage of battery cleaning and system maintenance is less concerned by investors properly. This leads to a reduced lifespan of the building, especially the heat collection efficiency of the panels is low, while if cleaned and maintained properly, the economic efficiency is not small. Mr. Huynh Duc Tien, living in Hoc Mon district, city. Ho Chi Minh has just signed a package contract with a company specializing in solar battery cleaning and maintenance of the solar power system with an investment of more than 1.2 billion VND nearly 2 years ago. Mr. Tien said that the cleaning company has specialized solutions, tools and techniques, so it is handed over to them for management because the cost is not much and it saves time.
