Home battery storage is now installed alongside 94% of new solar systems in the UK. In Hampshire, the combination of 1,750+ annual sunshine hours and high electricity prices makes battery storage one of the most financially effective home improvements available. A typical 10kWh battery adds £300-500 in annual savings on top of your solar generation savings.
Hampshire homeowners can choose from three main battery brands: Fox ESS (UK market leader, 35% share), GoodWe (free PLUS+ warranty extension programme), and SigEnergy (all-in-one 5-in-1 system). This guide compares all three for Hampshire homes, covering costs, warranties, grid export tariffs, and Octopus Agile compatibility.
