how much does solar cost

Costs

The installed cost of Tesla Powerwall 2 starts at £8270 + VAT. Storage capacity is around 13.5kWh and so this gives a cost of around £613 + 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.
