Picking the right solar battery size depends on your household’s electricity use and goals for solar storage. Typically, a 4 to 8 kWh battery suits most homes, covering evening and night usage by storing solar energy generated during the day.
Your choice should also align with your aims, such as grid independence or maximising solar usage, and take into account the upfront cost versus benefits.
Considering the UK’s less sunny winter months, a balance between battery size and solar panel output is crucial; an overly large battery may not be fully charged in winter, reducing cost-effectiveness. Also, future energy needs changes, like getting an electric vehicle, could impact the ideal size.
