A data interface system was constructed to enable the effective use of quasi-real-time solar radiation and solar power generation estimates based on data from the Himawari satellite in the energy management system. As one of the efforts introduced to apply meteorological data to the management of energy systems with renewable energy, we provided weather information to our solar car race team. We constructed a data interface system that provided data via web forms on the Azure cloud and on-premises servers. The implementation of a JSON format WebAPI enabled seamless data provision.
