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. |

DETAILED DESCRIPTION The present invention has been made in consideration of the above situation and has as its object improvement of both the heat collection efficiency and the power generation efficiency of a heat collecting panel (hybrid roof panel) with a solar cell.
It is another object of the present invention to provide a hybrid roof panel which can be easily assembled and has a high mass productivity.
To achieve the above objects, a first solar cell module comprises at least a base material, a first insulating material formed on the base material, a photovoltaic element set formed on the first insulating material and including a plurality of photovoltaic elements, and a second insulating material formed on the photovoltaic element set, wherein the base material has an L sectional shape, and a bent portion is formed in a portion where no photovoltaic element is arranged.
A second solar cell module comprises at least a base material, a first insulating material formed on the base material, a photovoltaic element set formed on the first insulating material and including a plurality of photovoltaic elements and a wiring material for electrically connecting the photovoltaic elements, and a second insulating material formed on the photovoltaic element set, wherein the solar cell module has a bent portion in a portion where the wiring material is arranged.
The base material has an L or W shape, and so an optimum raised angle can be freely designed by taking account of the place and the gradient of installation.
This increases the amount of power generation.
At the same time, this increases the heat collection efficiency and particularly helps recover the optical deterioration of a non-single-crystal semiconductor.
By incorporating the solar cell module with this shape into a heat collecting panel, a hybrid roof panel which generates power and simultaneously effectively uses heat is realized.
Especially in the second solar cell module of the present invention in which the base material has a W shape, the solar cell modules need not be connected to each other when the hybrid roof panel is assembled
