Smart Blue Co Ltd (Shizuoka City) established "Community-type Next-generation ICT Agriculture Model," which combines a solar-sharing system (agricultural solar power generation system), ICT, storage battery for self consumption, function of a disaster prevention base, etc, and started to operate it in July 2018.

Smart Blue introduced the model in a farm that had been uncultivable for a long time and regenerated it as a farmland.

An ICT system was introduced to (1) monitor not only agricultural environment plans (temperature, humidity, soil EC, PH, etc) but also the amount of solar electricity and failures of the solar power generation (PV) system and (2) remotely control a drip-watering system and the opening/closing of vinyl sheets on the lateral sides. Also, live cameras and five wireless cameras that can be moved in accordance with the growth state of plants under solar panels were introduced, realizing an "agricultural diary function" for recording daily agricultural activities.

Smart Blue installed both solar panels for selling power and solar panels for self consumption. The total output of the panels for selling all the electricity generated based on the feed-in tariff (FIT) scheme is 247.05kW while the total output of the panels for on-site consumption (agricultural ICT, well pump, drip-watering system, vinyl opening/closing system and night lighting) is 2.16kW. For the PV system, Jinko Solar Holding Co Ltd's monocrystalline solar cell module was employed.
