The analysis covers the current state of the market, key developments, and factors driving adoption of household battery energy storage systems.
In the realm of inventory challenges, European household storage products faced a historic surge in stock levels by the close of 2022. Adding to the predicament, the weaker demand observed in the initial half of 2023 has exacerbated the drop in shipments to the European household energy storage sector.
Further, in March 2022, the Institute for Power Electronics and Electrical Drives (ISEA) and RWTH Aachen University found that the home storage systems (HSS) accounted for 93% of the 1,357 MWh of new energy capacity installed in 2021, while the rest 7% includes industrial and large-scale storage segments.
According to Sunwiz statistics, the Australian household storage market achieved a noteworthy milestone in 2022, with a new installed capacity of 47,100 units and 589MVh. This represented a substantial year-on-year growth of 55.72% and 76.88%, respectively.
EESA predicts that household energy storage installations in major global countries will surpass 12GWh in 2023. In 2022, new installations in the global household energy storage market reached 7.38GWh, with CR5 countries (Germany, Italy, Japan, the U.S., and Australia) constituting 75.6% of the total.
These dual policies work synergistically to shorten the payback cycle of household solar and energy storage equipment by amplifying returns on electricity sales and reducing system costs. Consequently, they significantly enhance the economic viability of household energy storage in Germany.
Adding to the predicament, the weaker demand observed in the initial half of 2023 has exacerbated the drop in shipments to the European household energy storage sector. Notably, the decline in deliveries from international manufacturers to Europe was more conspicuous.
