The best all round residential solar storage product on the market is Tesla Powerwall 2, which we recommend for several reasons:
Solar self consumption
Back up power
This means we are trained to install Powerwall and have been approved by Tesla for continued adherence to strict quality requirements.
The installed cost of Tesla Powerwall 2 starts at £7200 + VAT. Storage capacity is around 13.5kWh and so this gives a cost of around £533 + VAT per kWh.
This is about as competitive as it gets... on a cost per kWh basis, pretty much every other system will be a similar cost or more expensive.
