Why are homes around the world installing energy storage systems?
3 Core Pain Points Explained
1. Soaring electricity costs: global electricity prices rose 35% (citing IEA data), the average annual cost of electricity for
U.S. households exceeds $1,500, energy storage systems can reduce 50% grid dependence.
2. Crisis of power outage: South Africa's average daily power outage is 6 hours, Philippines' typhoon season has frequent
power outages, hospitals/homes are in urgent need of backup power.
3. Environmental policy: EU 2030 renewable energy target, US federal tax credit of 30%, promoting the popularity of home
energy storage.
