Why consider a Powervault Solar Storage System?

    • Affordable cost: A Powervault battery (without a solar panel system) will cost between £2,000 – £2,800 depending on the type of battery and capacity you need. When compared to other market leaders like Tesla which starts at £5,400 or Sonnen at £4,500, this is a considerable saving. Why are they so much cheaper? Well, they have designed a battery specifically for the energy use of an average UK home (10kWh/day) meaning it can charge and discharge completely every day.
