A major hurdle to the wider adoption of renewable energy in UK homes is battery storage. Properties that generate power from, for example, solar panels must use it straight away or sell it back to the grid unless they have enough battery capacity to store it.

Solar batteries effectively allow you to make use of the electricity generated by your solar panels when you need it most. They are growing in popularity, with demand driven by sky-high energy bills and climate uncertainty, but cost and storage efficiency are still serious barriers to wider adoption.
