Ikea is now selling solar power systems and home battery packs in the UK, claiming people who sign up to the system can save up to £560 a year.

The Swedish retail giant says that by installing supersized batteries on their walls, homeowners can store the power generated by solar panels, most of which is never consumed by households.

While homeowners have long been encouraged to install solar panels on their roofs, prices have come down in recent years and the installation of lithium-ion batteries to store the energy is a newer phenomenon.
