Fig. 4 — Sales network of the distributed PV market and spatial distribution of newly installed distributed PV in Japan in 2018. a. Sales network of the distributed PV sector: There are three layers in the sales network. The first layer represents the distributed PV manufacturers, the second layer shows the distributed PV intermediators (wholesalers, installers, retailers, and leasers), and the third layer shows the two types of end-consumers. C represents the customers of PV intermediators. D represents direct customers of PV manufacturers. b. Spatial distribution of newly installed distributed PV. The position of the point shows the location of the installation. The deep color refers to the installation of solar PV with high capacity, while shallow color refers to the installation of low-capacity solar PV. The size of the point indicates the number of installations, where bigger refers to more, and smaller refers to fewer. (For interpretation of the references to color in this figure legend, the reader is referred to the web version of this article.)
