The Japanese carmaker's commitment to green energy extends beyond the garage.

Nissan has announced that its new integrated home energy solution is on sale in the UK. The new setup involves solar panels and reused batteries from the company's EVs, allowing homeowners to generate electricity even while they're not in the house and either sell it back to the grid at peak times or use it themselves. The whole thing is managed by a sophisticated computer system to best meet each household's requirements. 

Starting from £3,881 – which includes the supply and installation of a six-panel solar system, home energy management system, and VAT at 5 percent – the package also uses battery storage (xStorage Home) as well as the solar panels and energy management to reduce energy bills by up to 66 percent. It also has the ability to charge Nissan EVs.

'Nissan Energy Solar is a complete system for home energy generation, management and storage. It enables UK homeowners to make significant savings on their household electricity bills, and become champions of sustainability and green technology,' said Gareth Dunsmore, Nissan Europe's electric vehicle director. 'More than 880,000 people in the UK already use solar panels and this fully integrated solution brings a fresh opportunity to grow this number exponentially over the coming years.'

The energy storage system is a recent innovation for home electricity solutions, giving homeowners flexibility over how they use their electricity and when to best deploy what's been stored up from the sun. The setup helps not only to significantly reduce costs, but also to reduce the home's carbon footprint too, by automating energy flows to optimise solar energy production and battery storage capacity.

As well as the sophisticated hardware, Nissan has also created an app so that users can control the system remotely and monitor their electricity usage.
