  As described above, the upper end portion of the solar cell roof panel 3 is formed to extend under the ridge cap 45 on the ridge 5. As a result, the upper end of the duct 61 is under the ridge cap 45. The ridge cap 35 has a conventional inverted V-shaped cover sheet 47 designed to prevent rainwater from entering the building, and a plenum for collecting air flowing upward into the plenum chamber 49 along the duct 61. Chamber 49. The plenum chamber 49 extends across the roof and is generally trapezoidal (although it may be of any suitable shape), one chamber 49a for one roof facing direction and the other With a separate chamber 49 for the roof facing direction, the air from the colder side of the building can be used separately from the air from the side of the building facing the sun more directly. These plenum chambers 49 can be made of steel or any other suitable material, and are generally used to direct air collected from ducts 61 used in buildings for heating or cooling. Used.

  The plenum chamber 49 may include a fan (for example, one or more inlets (or spigots) (not shown) or other suitable elements along the length of the plenum chamber for forced air flow ( It may be connected to an air treatment system (not shown) including (not shown). The number of outlets generally depends on the size of the fan and the length of the chamber, and how the heated or cooled air is used in the building.
