On the roof will be solar panels, and nothing else. The panels are setup with a sun tracking system to give 50% more solar hours. This will allow for the building to generate as much electricity as possible to reduce the electric bill for the building. The solar panels will provide for the resources they need, and make things simply run better. Each unit will have a battery bank in the basement to assure that there is always electrical power even in the power outage. Without the battery bank, the SRO? will lose power for 2-5 seconds while the generator turns on. For those with desktop computers doing an OS? update, this could become a significant problem. The solar panels helps protect from such.
