Abstract: In order to promote and accelerate the development of comprehensive energy system in Lingang Special Area of China（Shanghai） Pilot Free Trade Zone（hereinafter referred to as "Lingang Special Area"）,this paper explores solar energy development and application models in many fields,such as the construction of distributed PV power stations on government and public building roofs,the simultaneous design of PV power generation system in new public buildings in industrial parks. A comprehensive energy implementation plan is proposed to expand the "PV+" scenarios,develop PV/T pumps and other solar thermal utilization methods,explore regional shared energy storage and new user-side energy storage systems,study new negative carbon technology and carbon asset full lifecycle management,and provide references for low-carbon development in Lingang Special Area.
