Antaisolar completes first phase of roof solar plant in Changtai County
Antaisolar has completed the first construction phase of its self-built roof solar plant by taking charge of the integrated services from investment, design, construction, connecting to grid and monitoring. The roof plant is installed on the cement roof of our factory in Zhangzhou, Fujian, covering the roof area of 2722 square meters.
The cement roof is flat, with no slant and no covering around. Therefore, based on the roof condition and the factory’s electricity consumption, the project utilized SC solar mounting system (installation angle of 20 °), with the installed capacity of 150 kilowatts. The project is expected to generate 150,000 KWh per year. Facing south solar array makes the whole system getting more sunlight all the year, which ensures the stable electricity generating, practical and economical.
During peak energy periods in summer, the electricity generated by the roof solar plant will be connected to the factory’s grid for production use. As a kind of strong supplement energy, the green power will create significant economic benefits for the operation of the factory.
