Chiba Ecological Energy Inc (Chiba City) announced April 1, 2019, that it has supported the planning and installation of an experiment facility for solar sharing (agricultural solar power plant growing grape trees under solar panels) at Chiba University of Commerce (CUC) (Ichikawa City, Chiba Prefecture).
Chiba Ecological Energy, which is a venture firm spun off from Chiba University, also announced April 9, 2019, that it has completed an agricultural solar power plant for growing Japanese pear trees in Kisarazu City, Chiba Prefecture, Japan.
The facility, "Chiba University of Commerce Solar Sharing Experiment Facility (Unit 1)," is equipped with 8.64kW of solar panels and a storage battery with a capacity of 13.05kWh. Electricity generated with the panels is consumed by the facilities of the university. At the time of power outage caused by, for example, a natural disaster, power can be supplied from the outlets of the facility, Chiba Ecological Energy said.
The areas of the mounting systems and solar panels are 130.66m2 and 54.95m2, respectively. The light blocking rate is about 43.1%. The solar panel, PV inverter and mounting system employed for the plant are products of Germany-based Luxor Solar, Germany-based SMA Solar Technology and Japan-based BSL. Also, DMM.com Ltd supplied the storage battery.
The project is part of the "CUC 100 Wine Project," in which students will brew wine in commemoration of the 90th anniversary of the university in the aim of completing the brewing by its 100th anniversary. The facility will be used for students to independently experience the production and processing of agricultural product.
Also, for the solar power plant for growing Japanese pear trees in Kisarazu City, mounting systems with a height (distance from the ground to solar panels) of 4m were introduced. The output of the plant is 69.12kW. All the electricity generated at the plant is sold to Tokyo Electric Power Company Holdings Inc (TEPCO).
The solar panel, PV inverter and mounting system employed for the plant are products of Luxor Solar, SMA Solar Technology and BSL, respectively. The light blocking rate is about 38.8%.
