UK house-holders can slash their domestic energy bills by up to two thirds by turning their homes into mini-power stations, claims Japanese car giant Nissan.
Excess energy collected via solar panels on sunny days and stored in a fridge-sized home-battery during off-peak times could be sold back to the national grid at peak times when demand for it is at its highest.
The system would also make it cheaper for ‘green’ householders to charge up their electric cars, the manufacturer said.

The firm unveiled its move into the wider energy market during the international launch of is new second-generation all-electric battery-powered LEAF car in Tenerife.
The Japanese car giant is also pioneering a system that use the energy stored in an electric car’s battery – while it is parked up unused at home – to help power homes and domestic appliances, or be sold back to the grid when the vehicle is not in use.
It is also using reconditioned electric car batteries to store power for villages in Africa.
Nissan said of its new operation called Nissan Energy Solar: ‘It aims to make renewable energy usage at home simpler and more affordable for UK residents – up to 66% savings in their energy bills.

The system, which uses technology adapted from electric cars, would also make it cheaper for ‘green’ householders to charge up their electric cars
‘It has been designed to allow UK homeowners to reduce their energy bills and get more independence from the grid, allowing them to live more sustainably.’
The system includes a home energy management system that will allow users to control how and when they want to use their energy.
Nissan said: ‘This reduces energy costs and carbon footprint for homeowners significantly, by automating energy flows, purposefully utilizing solar production peaks and storage capacities.’
The firm said Nissan Energy Solar will combine ‘world-class residential solar panels’ with an energy storage system to boost the energy efficiency of UK homes.
A Nissan spokesman explained: ‘Traditionally, solar energy has been used to power home appliances during the day.
‘But now with Nissan Energy Solar, householders can collect and store the excess energy from their solar panels and use it during the night and on cloudy days – even to charge their Nissan LEAF.’

The Nissan Energy Solar system starts from £3,881 which includes the supply and installation of a six-panel solar system. The Leaf is priced from £21,990 to £27,490.
To emphasise its ‘green’ credentials, the international launch of the new LEAF was held at the pioneering Institute of Technology and Renewable Energies (ITER) facility on the Spanish island Tenerife in the Canary Islands whose facilities and environmentally-friendly village is powered by energy from solar panels and giant windmills.
Francisco Carranza, managing director of Nissan Europe’s energy arm said: ‘Solar panels have become the world’s fastest growing source of new energy and we’re thrilled to launch Nissan Energy Solar in the UK.
‘More than 880,000 UK homes already have solar panels installed and they are seeing the benefits every day, from decreasing electricity bills to increasing property values.’
