As a result, the popularity of storage battery manufacturers is mostly concentrated in the top four companies. The top two companies account for more than 50% of the market share.

Aggregate results
Sharp 9.5kWh: 14.5%
Choshu Sangyo 9.8kWh: 13.1%
Omron 9.8kWh: 9.2%
Sharp 6.5kWh: 8.4%
Nichicon 9.9kWh: 6.2%
By model, Sharp 9.5 kWh became the most popular. Unlike Nichicon, which offers a wide range of products in detail, Sharp seems to have a certain amount of product lineup.
◆Summary of survey results
In the ranking of storage batteries by manufacturer, Nichicon, which has a wide lineup, ranked first. However, looking at each model, Sharp seems to be popular because it sells well-established models. Furthermore, although I do not know from this ranking alone, since Choshu Sangyo 9.8 kWh is supplied by Omron, it can be said that Omron 9.8 kWh was practically the most supplied to the market.
