The Swedish furniture retail giant first starting solar panels in the UK back in 2013 to grow on a (then) heavily subsidized green energy market but ceased sales in 2015 when the British government announced its plans of cutting solar subsidies by up to 90%. Just a few months later, IKEA returned with a new lineup of home solar panels, this time partnering up with the firm SolarCentury.

"An average solar home in the UK will typically consume around 40% of all the solar electricity generated, or even less if they are regularly out during the day," IKEA explains in a new statement. "The remaining 60% of unused solar electricity is sent back to the National Grid, at a loss compared to its value. This means that homeowners currently lose out on making further cost savings. By adding Solar Battery Storage, unused solar electricity can be stored and used at a later time, meaning the amount of solar electricity an average home can use doubles to 80%."

With the launch of its Solar Battery Storage system, IKEA/SolarCentury hope to tap into a rapidly growing market and rival Tesla/SolarCity's Powerwall and other, lesser-marketed solutions.
