We run the whole of our stable yard on solar power, lighting, sockets, electric fencing etc. Best thing we ever did.

Electricity company wanted £10,000 to connect us to a supply which already runs across one of our fields.

We would have had to dig a 1M deep 200yd trench lay the cable and do all the connections on the yard. All they would do would be to do the main connection at the other end (transformer box thingumy is already there).

The solar system is miles cheaper for us. Dont know about domestic dwellings though.
