Japan Nagano 18MW Solar Park is expected to generate 20,000 MWh electricity average annual to meet the demand of 5,500 families. 72,000 ASTRO modules were installed on the north side of Nagato Farm (around 33 hectares). Nagato Farm raises about 190 dairy cows to produce and sell cheese, yoghurt, and milk. Land lease income Ұ50 million per year from the solar park will be used as farm management by expanding dairy manufacturing facilities and subsidizing dairy operations.
