A solar battery module includes: a plurality of solar battery cells, a plain shape of each being a substantial rectangle, and a ratio of a short side length and a long side length of the substantial rectangle being 1/n:1 (n is an integer equal to or larger than 2), includes a plurality of light-receiving-surface bus electrodes parallel to the short side of the substantial rectangle on a light receiving surface, and includes rear-surface bus electrodes each at a position on a non-light-receiving surface corresponding to each of the light-receiving-surface bus electrodes; and a light-receiving-surface lead (an interconnector) that electrically connects the light-receiving-surface bus electrodes of one of the solar battery cells to the rear-surface bus electrodes of adjacent one of the solar battery cells.

Solar battery module and manufacturing method thereof

A terminal box for a solar cell module is composed of, a box body, an inner cover and an outer cover, wherein the box body includes a bottom plate, an outer plate arranged in an upright manner around the bottom plate, and an inner plate arranged also in an upright manner inside the outer plate to enclose a circuit housing area; the inner cover includes a top plate and a side plate extended downward from an outer circumference of the top plate, and is formed into a lid shape and fitted around an outer surface of the inner plate to cover the circuit housing area; and the outer cover is fitted around the outer plate of the box body to thereby cover the inner cover and the box body, wherein the terminal box further includes a fitting member that causes the inner cover to be fitted to the box body to thereby prevent the inner cover from being removed from the circuit housing area.
