The 75AmpHr battery is used to store the charge from the panel. This was bought for £15 on eBay.
12V LED lamps were used in external holders to light the main shed, the outside toilet and the wood shed. Where 2 lights are used it is important to connect them on a parallel circuit.
The total cost of the installation was around £120. I did re-use some of the existing wiring and switches
