Overview
Renewable energy projects such as photovoltaic power stations and wind farms are commonly constructed in remote suburbs, mountainous regions, coastal zones and wilderness areas. These sites feature harsh open-air operating conditions including strong winds, high humidity, intense ultraviolet radiation and extreme temperature differences. Wind and solar power generation exhibit inherent intermittency and fluctuation, placing high requirements on equipment environmental adaptability, operational stability and power quality regulation capability. QDTB® provides comprehensive power equipment solutions for the new energy sector.
