Photovoltaic Energy Storage EPC refers to a mode of undertaking the entire process of an integrated "photovoltaic power generation + lithium battery energy storage" project. It covers project design, equipment procurement (including PV modules, lithium battery energy storage systems, bracket materials, etc.), engineering construction, commissioning and operation and maintenance, aiming to provide customers with "one-stop, full-cycle" clean energy solutions. It is the mainstream mode for the implementation of current photovoltaic energy storage projects (such as industrial and commercial distributed photovoltaic energy storage projects, large-scale ground photovoltaic energy storage power stations).
