<p>PROBLEM TO BE SOLVED: To provide a sunlight utilizing roof which improves sunlight utilization ratio with respect to a roof area. SOLUTION: A plurality of solar battery panels 21, 22 are arranged on roof surfaces 14, 15 in longitudinal and transverse directions, and solar heat collectors 30 are arranged on roof surfaces on which the solar battery panels 21, 22 are not provided. The solar heat collectors 30 are each of a simple structure which heats heating mediums by sunlight, and the solar heat collectors 30 can change the shape and size thereof more freely than the solar battery panels 21, 22. Therefore, even if a remaining portion of the roof surface other than the portion on which the solar battery panels 21, 22, is not large enough for the solar battery panels 21, 22 to be set, the solar heat collectors 30 can be arranged on the remaining portion. As a result, the solar battery panels 21, 22 and the solar heat collectors 30 can be arranged on the roof surfaces 14, 15 without a gap, which enhances the utilization ratio of solar energy with respect to the roof area.</p> |
