Jared Campbell points out the unique design elements of his Salt Lake City home that take full advantage of the position of the sun year-round. In summer the sun does not shine directly into the home, keeping it cool, but in winter the low angle of the sun heats up the steel wall to the right that collects the sun's heat through a thermal battery. Rocky Mountain Power is seeking to impose a monthly $4.65 "facilities charge" on net-metered customers like Campbell to ensure they pay their share of the grid's fixed costs.
