In order to ensure long-term reliability when a photovoltaic element is bent or curved to be deformed: (1) In a method for manufacturing a solar cell module having a photovoltaic element encapsulated with a resin on a support member, the step is adopted which forms a bent portion in the photovoltaic element and in the support member, wherein the formation of the bent portion is performed while reducing a working pressure in the normal direction to a surface of the photovoltaic element; and (2) In a solar cell module comprising a photovoltaic element comprising at least one photoactive semiconductor layer on a flexible substrate, at least a part of the flexible substrate is subjected to tensile deformation in the direction parallel to a surface of the substrate with a strain less than a critical strain to lower the fill factor of the photovoltaic element, whereby the photovoltaic element is deformed.

A solar cell module according to the present invention includes at least a base material, a first insulating material formed on the base material, a photovoltaic element set including a plurality of photovoltaic elements formed on the first insulating material, and a second insulating material formed on the photovoltaic element set. The base material has an L or W shape. In one embodiment, the base material has an L section shape, and a bent portion is formed in a portion where no photovoltaic element is arrange. In another embodiment, the photovoltaic element set includes a wiring material for electrically connecting the photovoltaic elements, and a bent portion is formed in a portion where the wiring material is arranged. Power generation and heat collection efficiency are increased, and optical deterioration of a non-single-crystal semiconductor are decreased in the present solar cell modules. By incorporating the present solar cell modules into a heat collecting panel, a hybrid roof panel with effective power generation and heat use is obtained.

A solar cell module is provided at the position of a heat collecting plate inside a heat collector, at the position of its window member or at the position of its bottom plate. With such constitution, a hybrid system can be achieved in which the hot air can be led into a house while maintaining the performance of solar cells making use of amorphous silicon semiconductors.In the case where solar cells are provided at the position of the heat collecting plate, a resin used as a filler has so high a thermal resistance that the heat conduction to the air may be insufficient to make it impossible to obtain hot air having a sufficiently high temperature. To solve this problem, the solar cell module is made to have a smaller thermal resistance on the non-light-receiving side than the thermal resistance on the light-receiving side.

A roof unit is constructed in such an arrangement that a plurality of combination solar battery and roof panels, each having flanges at two opposite sides, are placed adjacent to each other with clearance on a joining/fixing member, the adjacent combination solar battery and roof panels are fixed to the joining/fixing member in the clearance by a removable fixture, and a removable cap is placed in an upper part of the clearance. This arrangement simplifies the work at a work site, decreases the construction cost, and decreases work errors. In addition, measurement or replacement of each module can be made even after mounting, thus providing a practical vertical-roofing roof excellent in maintainability and also in wind endurance.
