At my last home I had no power in the garage. I rigged the biggest external panel i could get on the wall.
Took a feed through from the battery through the plyboard near the centre of the seats with connectors from europarts, but RS and Halfords do similar
The company i purchased from are below, worth a look and they are knowelgable to talk to.
