Solar power supply street lighting

A few days ago, the reporter learned from the Dongjiang Industrial Zone of Shuikou Street in Huicheng District that the Tianbao Electronics (Huizhou) Co., Ltd. of the industrial zone will launch a “PV roof” plan in the second half of this year to realize the solar power supply companies themselves.

At present, the company uses solar power systems to provide street lighting in the factory area. The reporter saw that two lights were installed at the security kiosk at the entrance of the factory and a small photovoltaic roof system was used at the roof. "The two-and-a-half kilowatt-hour street light will illuminate this area every night at 7 pm," said the company's staff. Subsequently, the reporter came to the photovoltaic research laboratory of the R&D headquarters of Tianbao Group, and some technicians are debugging the equipment. “PV inverters and electric vehicle charging equipment have all come out of these, and we have continuously tested and improved it. We need to pass the Golden Sun certification before we can produce in batches. It is expected that solar inverters will be certified at the end of the year and can be mass produced next year. ”

Can solar inverters be applied to ordinary families? The chairman of the company, Hong Guangyin, told reporters that at present, it is only used for street lighting in the factory. “At the end of the year, you can see that more than one-third of the electricity in our factory is solar power.” According to relevant statistics, the total annual sunshine amount in Huizhou is 2,000. For many hours, a 100-square-meter roof of a residential house uses photovoltaic power to produce about 12,000 kWh of electricity each year, requiring the use of two 5-kilowatt or 11-kilowatt inverters. It can meet the basic electricity needs of a family's lighting, televisions, refrigerators, computers, air conditioners, etc. This can save energy and reduce emissions, but also effectively reduce the load on the grid. “Only people who buy photovoltaic building materials will have higher costs.” “Solar power generation can also be used to charge electric vehicles. Our company has planned to build the first charging demonstration station in Huizhou. It is estimated that it can provide 5 electric vehicles at the same time. The bus and five cars provide fast and slow charging services. However, this project needs to be completed with strong government support."
