HOME BATTERY WITHOUT SOLAR - SAVINGS AND BENEFITS

EV Channels Review

This video debunks the common misconception that home battery systems require solar PV, arguing that batteries alone can be financially more sensible due to predictable, year-round savings. The reviewer emphasizes the importance of time-of-day electricity tariffs, where charging a battery during off-peak hours (e.g., 7p/kWh) and using it during peak hours (e.g., 27.5p/kWh) can lead to significant daily and annual savings. For instance, a daily usage of 10 kWh could result in approximately £693.50 annual savings. The video also provides guidance on sizing a battery, suggesting that it's often unnecessary to cover 100% of daily usage, especially when load shifting appliances like dishwashers and washing machines to cheaper periods. A buffer of about a third more than the calculated need is recommended to account for degradation and unexpected usage. The reviewer highlights that while installation costs vary, prioritizing reputable installers who offer excellent customer service and aftercare can be worthwhile. The video also touches upon the benefits of battery backup during power outages and advises viewers to research specific tariffs and battery sizes based on their individual needs and future energy consumption plans, rather than oversizing systems unnecessarily.
