What this means is that to meet the typical energy needs for this time frame you will need a battery that is around 10 kwh in capacity with a power rating of at least 5 kw.

It used to be considered by many that the uk did not receive enough sunshine to justify investing in solar power. You will need a roof space of about 680 sq ft for a 10kw system.
