Elon Musk’s Tesla Powerwall better watch its back; the British arm of IKEA says it will be offering battery storage for its current range of rooftop solar panels. For homes that generate more power than they use, this will allow them to stow the excess for a cloudy day, rather than watch it dissipate through the national grid. Despite its do-it-yourself ethos, the Swedish mega-retailer won’t be cranking out the batteries itself. Instead, IKEA has teamed up with Solarcentury, the largest solar provider in the United Kingdom, to source the cells from the likes of LG and Sonnen.

IKEA has at least one thing going for it that Tesla does not: scale, which can tamp down costs. Depending on location, type of building, and ease of installation, the company says its solar and battery products will start from £3,000, or about $3,970 in American dollars. A 14 kilowatt-per-hour Powerwall, on the other hand, costs a smidge over £5,000 ($6,617).

Still, there are cheaper alternatives. As British Wired points out, Powervault, a U.K. startup, lets you build your own home battery solution from £2,500 ($3,307).

Theoretically, widespread adoption could lead to lower prices in the long run. And for the tens of millions who have struggled with Allen wrenches and clouds of pine dust, IKEA is a familiar—and generally trusted—quantity.

“We know that our customers want to live more sustainably and together with Solarcentury we will help them to get more value from their solar panels and do just that,” said Hege Saebjornsen, IKEA’s sustainability manager for U.K. and Ireland, in a press release.
