Could new batteries take you off grid?

For many years we have wondered about the problem of storing our PV generation. In fact many customers install PV, thinking that they may be protecting themselves from future power cuts, without realising that the grid is required for their system to function.
A new development from Tesla Motors, the electric car manufacturers, may be about to solve that problem. They have now developed a home battery, based on the ones used in their cars and claim it could revolutionise the ‘entire energy infrastructure of the world’.
The new system, called Powerwall, is likely to be on sale in America this summer, so it will still be some time before these become common place in the UK. With two sizes planned, a 7kWh and a 10kWh system and prices from around £2,000 there is much to look forward to, but these sizes are still very small compared to our current energy use which DECC calculated to be around 4,192 kWhs for the average UK household in 2013 (1). However, with a decent PV system and sensible use of electricity, including staggering appliance use, they could be perfectly adequate for an average UK house.
