PROBLEM TO BE SOLVED: To provide a commodity information display system by which commodity information can be preferentially provided to customers who supplied power to a power storage part.SOLUTION: A commodity information display system 10 comprises: photovoltaic power generation devices 20 and display terminals 30, which are provided to houses 12A, 12B, 12C respectively; a power storage part 40 charged by each of the photovoltaic power generation devices 20; a management device 60 which is provided to a store 50 and manages commodity information; and a center server 70 which identifies houses 12 which charged the power storage part 40 and transmits the commodity information to them. The center server 70 receives the commodity information transmitted from the management device 60 and identifies the houses 12 which charged the power storage part 40. Then, it transmits the commodity information to the display terminals 30 of the identified houses 12. Thus, it identifies the houses 12 which charged the power storage part 40 as customers, and therefore it is capable of preferentially providing the commodity information to the customers who supplied power to the power storage part 40. |
