The electric room is a little intimidating. There will be all of the lines from the solar panels to come in, and feed into the battery banks. There is also a circuit panel which will be used to selectively turn off a room to allow for proper workings. In addition to the solar lines, there will be the electricity as provided by the electric provider. The meter will be inside the electric room which will be electronically read from the electric company to provide for accurate billing. Keep in mind that with the solar panels, the excess electric will be sent to the grid for credit.
