[Original Report Vol.16] Is the common sense that “storage batteries are a loss” really correct? The most popular reason for purchasing a storage battery, knowing that it would be difficult to get the money back, was “lower electricity bill when combined with solar power” at 44.2%.
～85.6% of buyers say they are satisfied～

Kokusai Kogyo Co., Ltd. (Headquarters: Shinjuku-ku, Tokyo,
Representative Director and President: Satoshi Hijikata) provides “Enegaeru (https://www.enegaeru.com/),” an economic effect diagnosis for solar power and storage batteries. We would like to inform you that we conducted a fact-finding survey on the merits of purchasing residential storage batteries, targeting 104 people who purchased storage batteries for their homes despite knowing that it would be difficult to recover their investment. There is a common belief that “storage batteries cannot be repaid, so it is better not to buy them” (from the seller’s perspective, it is better not to sell them), but the survey results show that “storage batteries cannot be repaid, but there are still clear advantages to purchasing them”. It was suggested that there is.

・Age 40: Although it will take time to recover the investment, I have determined that I can recover my investment if I use it for a long time.
・64 years old: I couldn’t install solar power generation, but I wanted to know about the usability and cost of storage batteries.
・31 years old: For emergencies.
・65 years old: I had extra funds.
・52 years old: I knew that the price of electricity sold would be lower than when I installed solar power generation. As there was a growing trend towards emphasizing base electricity, we decided that we needed to be prepared to increase our own consumption, as there was a possibility that we would not be able to sell electricity.
・62 years old: I felt like my utility bills were cheaper in my daily life. ・28 years old: Because I can use my energy effectively.

summary
This time, we conducted a fact-finding survey on the merits of purchasing residential batteries, targeting 104 people who purchased residential batteries despite knowing that it would be difficult to recover their investment.
First, when asked about the details of the residential storage battery purchased, the most common manufacturer was “Panasonic” (26.0%), the most popular was “5-10kWh” (43.3%) in terms of capacity, and “a major housing manufacturer” (24.0%) was the most popular choice in terms of place of purchase. I did. In addition, 78.8% of them placed emphasis on “calculating the investment payback period” before purchasing a storage battery, and the reason why they purchased a residential storage battery despite knowing that it would be difficult to recover the investment was “The combination of solar power and storage battery will help The top responses were “To lower
electricity bills” (44.2%), “To reduce the unit price of electricity sold” (40.4%), and “To reduce CO2 emissions and contribute to the environment” (37.5%). ) and “To satisfy curiosity and interest in new products and technologies” (23.1%) were also cited. Furthermore, regarding their level of satisfaction with the residential storage batteries they purchased, 85.6% responded that they were glad they purchased them.
This survey revealed that, in addition to economic rationality, environmental considerations and interest in new technologies influence the motivation for purchasing residential batteries. Values other than economic benefits are important deciding factors for buyers, such as reducing electricity costs by using solar power and storage batteries as a set, contributing to the environment, and preparing for power outages. It suggests possibility. In the storage battery sales industry, it is necessary to take an approach that meets the diverse needs of consumers and to clarify the long-term economic effects.
