I just finished expanding a shed on the side of my workshop building to create a carport (details on my blog). I find this setup to be practical and the install was very simple. Just pulled Romex 10/3 wire from the breaker box 25 ft and through the wall to the meter box. I installed the Voltec charger on the outside corner along with my own meter that I got used/reconditioned on eBay so I can track the energy used to charge the Volt. Most of the charging power comes from our 5.2kW solar array.
