The average annual savings from using a residential energy storage system can vary significantly depending on several factors, including the type of tariff (e.g., Time-of-Use), the presence of solar panels, and local electricity costs.
With Solar Panels:
- For a typical household using about 10,000 kWh annually, combining solar panels with energy storage can save between USD $1,500 and $2,500 per year.
- Savings can reduce electricity bills by 70-80% in some cases, compared to around 50% without batteries.
Without Solar Panels (Only Load Shifting):
- Savings are generally less and depend heavily on the differential between peak and off-peak electricity rates.
- A UK household might save approximately £280 per year by charging batteries during off-peak hours and using the stored energy during peak hours.
Additional Factors:
- The effectiveness of the system also depends on usage patterns, system efficiency, and any available incentives or rebates, which can significantly impact the financial benefits.
Overall, while the specific annual savings can vary widely based on these factors, residential energy storage systems can provide substantial financial benefits, especially when combined with solar panels.
