Abstract:
1. A solar module comprising: a solar cell with a light-receiving surface and a back surface; and an encapsulant sealing the solar cell, wherein the encapsulant includes a ratio of a thickness of the back surface side encapsulant at an end surface thereof to a thickness of the back surface side encapsulant at a region where the solar cell is provided ((the thickness of the back surface side encapsulant at the end surface thereof)/(the thickness of the back surface side encapsulant at the region where the solar cell is provided)) is smaller than a ratio of a thickness of the light-receiving surface side encapsulant at an end surface thereof to a thickness of the light-receiving surface side encapsulant at a region where the solar cell is provided ((the thickness of the light-receiving surface side encapsulant at the end surface thereof)/(the thickness of the light-receiving surface side encapsulant at the end surface thereof)), further comprising: a light-receiving surface material located on the light-receiving surface side of the encapsulant and made of glass; and a back surface material located on the back surface side of the encapsulant and made of a resin sheet and wherein the distance between the glass and the resin sheet at a region where the solar cell is provided is larger than the distance between the glass and resin sheet at the end surface and wherein water vapor transmission rate of the back surface side encapsulant is higher than that of the light-receiving surface side encapsulant.
