The Hefei Institute of Construction Inspection's 660kW distributed photovoltaic power generation project, undertaken by Anhui Taisang Energy Co., Ltd., integrates photovoltaics, energy storage, DC charging, and wind-solar hybrid lighting. It utilizes 1,200 JinkoSolar 550W photovoltaic panels, five 110kW inverters, and one 50kW inverter from Sungrow. The system generates an average annual power of 639,900 kWh, with 65% of its power consumed by the park. This system utilizes a "self-generated, self-used" model with surplus power fed to the grid, ensuring stable energy consumption for the park while effectively reducing electricity costs. The park's split-type DC charging stations can simultaneously charge four new energy vehicles, alleviating concerns about recharging and enhancing the convenience of green travel. The park's 7.5kW off-grid breeze system cleverly utilizes low wind speeds. Its highly optimized wind energy capture efficiency, combined with advanced permanent magnet generator technology, achieves efficient energy conversion even in urban microclimates, contributing approximately 9,500 kWh of green electricity annually.
