Shandong Hongtai Electric Co., Ltd. (“Hongtai”) constructed a rooftop distributed PV power station of 9.2528 MWp (4.8 MWp for Phase I and 4.4528 MWp for Phase II), which was connected to the grid and put into operation on December 30, 2017. The project is built following the principle of generating power for self-consumption by Hongtai and feeding surplus power to grid, aiming to help Hongtai to build a zero-carbon park.
