'Roof-type solar panels' over 500-car space

Located a roughly 50-minute drive from Tokyo and about a 10-minute drive from Narita Airport, "Shisui Premium Outlets" in Shisui-machi, Chiba Prefecture, Japan, boasts relatively good access among the outlet malls in Japan. A total of about 180 famous domestic and international brands are housed in the site, which was designed in the image of a town in the US.

Mitsubishi Estate-Simon Co Ltd (Chiyoda-ku, Tokyo) set up a carport-type solar power generation facility (PV carport) with an output of about 1MW in part of this outlet mall's parking lot, which consumes the entire amount of power generated at the site. The company started operating this power generation facility in December 20, 2017 (Fig. 1).

This facility is expected to function not only as a measure against global warming, but also as heat insulation and rain cover that would greatly benefit customers visiting by car by increasing convenience. This is Mitsubishi Estate-Simon's second PV carport introduction following "Ami Premium Outlets" in Ami-machi, Ibaraki Prefecture (See related article).

At Shisui Premium Outlets, 3,960 roof-type solar panels were set up over the eastern space for about 500 cars in a 4,200-car parking lot surrounding the store area. Many cars from the direction of Narita City are parked on the eastern side, and in most cases, cars are reportedly parked in the shade under the PV carport.

Some carports have auxiliary posts on the open side along with main posts, but the one adopted at the outlet mall in Shisui is a "single-post" type that supports the roof with posts on one side only. Moreover, as there are no braces between posts, drivers can park their cars completely without fear of hitting the carport facility.
