Pre-emptive solar planning
Our under-construction house is designed for energy efficiency, although we are not making the jump to solar/photovoltaic due to cost restraints at present. However, our metal roof has been designed and sited so that solar panels may eventually be installed once the technology becomes more affordable. In the meantime, while we are building, should we be running some sort of conduit from the roof to ?somewhere (basement?) in anticipation of future solar power? Or would any cables/wires from PV panels run on the outside of the house/roof?
