We as One Vision supplied and fitted a Tesla battery storage, alongside providing a 5.94 KW PV system at Nantgarw Cemetery, Wales. The Tesla battery is called 'Tesla Power Wall 2', which is a 13.5 KW hour battery. 

The Tesla battery 2 is useful as when more power needs to be used, the Tesla battery will provide the extra  power. The battery typically uses approximately 10 KW hours per 24 hour period. When the PV pannels have stopped operating in the evening the battery will supply the electrical loads required by the building.

 There is a Smart Phone app available which is convienient to control the power usage, the app can control and keep track on how much electricity is being used, at any given time. The Smart Phone controls when the battery is charging and discharging, and showing how little grid electricity the building is consuming.

It is also possible to charge the Powerwall with electricity on an economy rate, this is especially useful in winter periods,  when there is less solar energy, being produced by the PV solar panels.
