Earth- and wallet-friendly
Starting with SDGs actions with household storage batteries

To live an earth-friendly life using solar power that only generates power during the day Did you know that you need a home storage battery?
It also saves on your electricity bill, and you can rest assured that you can use electricity even during power outages due to disasters, etc. There are many situations where household storage batteries are useful in your life. So, let's ask the person in charge of the ITOCHU Corporation Battery Business Section, which handles the next-generation storage system "SmartStar Series"!
Pros and cons, from monthly costs to savings. We learned more about household storage batteries, which are still not very familiar.

Q What is the purpose of using home storage batteries?

A "A home storage battery is a device that stores electricity so that you can use electricity generated by solar panels during the daytime at night, or buy cheap electricity at night and use it during the daytime. Nature It is essential for living with energy.In recent years, more and more people are using it to prepare for power outages caused by disasters.Our "SmartStar3" is made from sunlight. You can save eco-friendly electricity to charge your electric vehicle.In addition, data shows that households using solar panels can save about 3,000 to 4,000 yen on their monthly electricity bills."

Q What is the difference between the next-generation energy storage system "Smart Star3" and conventional household storage batteries?

A "Since it is equipped with an AI function, it is possible to automatically manage charging and discharging according to the usage situation of the household. In the past, people had to think about how to use storage batteries, such as "Let's use the storage battery's electricity to free up as much capacity as possible" or "There's a typhoon forecast for next week, so let's not use the storage battery's electricity until then." Leave everything to the next-generation power storage system "SmartStar3".Dedicated AI analyzes and learns in detail the days and times of the week when electricity is often used in each home.Combined with the weather forecast, you can know when the electricity will run out and when It predicts whether there will be a surplus, and controls charging and discharging in an eco-friendly and economical manner according to the user's lifestyle pattern, such as buying the shortfall of electricity from the electric power company at night when it is cheaper. , In most cases, the outlet that can be used with conventional storage batteries is limited to one place, but with 'SmartStar3', it is very convenient that you can use any outlet in the house."

Q I also want to know the disadvantages of "Smart Star 3"!

A "There are no demerits worth mentioning, but if I had to mention it, it would be the large size due to its large capacity. External dimensions are 118.2 cm wide x 100.8 cm high x 39.2 cm deep, and weighs 265 kg. Therefore, depending on the home environment, there are rare cases where installation is not possible due to physical problems.”

Q Is using storage batteries a greener choice?

A "When used in combination with solar panels, natural energy from sunlight can be efficiently circulated in the home, so it can be said to be environmentally friendly. Without storage batteries, When bad weather continues, solar power generation alone is not sufficient for households that have contracts with non-renewable power companies to purchase electricity from them. It can be said that it is an earth-friendly choice because the natural energy generated by the installed solar power can be used all day long, even during bad weather days and nights.”

Q Can I use it without using a solar panel?

A "Of course it is possible. If you have a contract with a plan that has a low electricity bill at night, you can save the nighttime electricity in a storage battery and use it during the daytime when the electricity bill is high to reduce your electricity bill. By the way, if you have solar panels installed, you can use the zero-yen electricity you generate at home during the day, and you can store the unused amount in storage batteries, so it's definitely eco-friendly and economical."

Q What is the monthly cost of using "Smart Star3"?

A "If you use Panasonic's solar power generation system "HIT" and the set monthly flat-rate service "Bee Flat", you can use it for about 30,000 yen per month (15-year contract). The installation cost of the panel and storage battery is free.Originally, the installation cost is high, so it is quite profitable.In addition, after the contract expires, the storage battery and solar panel that you have been using will be transferred as they are without removing them. "

Launch of a service that allows self-consumed energy to be returned to points

The industry's first service that gives points according to the amount of consumption of electricity generated by solar power generation at home. Grid share points (environmental points)”. Points can be exchanged for your favorite points and various services through dot money byAmeba.

It is said that 90% of Japan's greenhouse gases are CO2 coming from fossil fuels. Using natural energy from solar power generation, which does not produce air pollutants, will lead to actions to prevent global warming. In order to protect the beautiful earth and your precious family, how about adding the option of "household storage battery"?
