This is a household power generation system that uses a combination of photovoltaic panels and batteries. The system was developed by the Sony Computer Science Institute and other units. The biggest feature is that when there is surplus power generated by the electricity generated in its own home, it can automatically provide power to the neighbors with insufficient power. This is not a simulation test, but a technology that has actually operated in 19 houses where residents live. The green part of the large square represents the households equipped with this power generation system. The gleaming dashed line connecting these green squares represents the real-time exchange of power between households, enabling energy assistance among residents.
