Residential Energy Storage Market by Power Rating, Connectivity, Technology, Ownership, Operation, Region - Global Forecast to 2028

Jul 12, 2023

Connectivity, Technology, Ownership, Operation, Region - Global Forecast to 2028" - The 6 – 10 kW, by power rating, is expected to be the largest and the fastest-growing market from 2023 to 2028 The residential energy storage market is categorized by application into three segments: 3-6 kW, 6-10 kW, and 10-20 kW.Among these segments, the 6-10 kW segment is projected to hold the largest market share and exhibit a high CAGR during the forecast period. This dominance can be attributed to the reduced reliance on grid supply enabled by energy storage systems, which serve as backup power sources in the event of grid outages. By offering backup capabilities, the 6-10 kW segment provides homeowners with increased energy security and resilience. The lithium-ion segment, by technology, is expected to be the fastest-growing market from 2023 to 2028 Lithium-ion and lead-acid batteries make up the two technology segments of the residential energy storage market.The market for lithium-ion batteries is expected to grow most rapidly. The strong growth rate can be due to the rising number of lithium-ion battery manufacturing facilities and high expenditure in their R & D. The Customer-owned, by ownership type, is expected to be the largest and the fastest-growing market from 2023 to 2028 The residential energy storage market is categorized based on ownership type, including customer-owned, utility-owned, and third-party-owned systems.Among these segments, the customer-owned segment is projected to experience the highest growth rate during the forecast period, closely followed by the utility-owned segment. This dominance can be attributed to the advantages customers gain, such as lower energy bills and increased energy independence, through the implementation of residential energy storage solutions. By owning their energy storage systems, residential customers can optimize their energy usage, store excess energy, and rely less on external energy sources, leading to greater cost savings and enhanced self-sufficiency.
