## Abstract

The solar cell module includes a solar panel that includes a transparent substrate and is configured by aligning solar cells, a reinforcing frame arranged on the back surface of the solar panel, and a shock absorbing unit arranged between the solar panel and the reinforcing frame, where the shock absorbing unit has the first main surface facing the solar panel, which is a flat surface, and a second main surface facing the reinforcing frame, which is a curved surface bowed in the longitudinal direction of the reinforcing frame, having an arc shape in cross section, and convexed toward the reinforcing frame side.

## Claims

### Claim 1

A solar cell module, comprising:
a solar panel that includes a transparent substrate and is configured by aligning solar cells;
a rectangular frame surrounding an entire perimeter of an edge of the solar panel, and the rectangular frame includes a pair of opposing long frames and a pair of opposing short frames, and a notch is provided in a center, in a longitudinal direction, of a back surface of each of the long frames;
a reinforcing frame engaged with the notch of each of the long frames and arranged across a back surface of the solar panel; and
a shock absorbing unit arranged between the solar panel and the reinforcing frame,
wherein the shock absorbing unit has a first main surface facing the solar panel, and the first main surface is a flat surface, and
a second main surface facing the reinforcing frame, the second main surface including a plurality of projections extending in a direction orthogonal to a longitudinal direction of the reinforcing frame, in which a curved line smoothly connecting ridge lines of the projections to one another defines a line having only a single curve between terminal ends of the second main surface in a longitudinal direction of the reinforcing frame, and is an arc-in-section curved surface line convexed facing the reinforcing frame, wherein
the projections arranged at the terminal ends are configured to be triangular in cross section and a top surface thereof continues to the flat surface such that the shock absorbing unit has no end surfaces in the longitudinal direction of the reinforcing frame.

### Claim 2 (depends on 1)

The solar cell module according to claim 1, wherein the shock absorbing unit is adhered to the back surface of the solar cell panel.

### Claim 3 (depends on 1)

The solar cell module according to claim 1, wherein a plurality of shock absorbing units are arranged in the longitudinal direction of the reinforcing frame.
