Solar electric power apparatus, solar module, and installation method of solar modules

摘要

In a solar electric power apparatus provided with a plurality of solar modules that are ranged in such a manner that edges of adjacent solar modules are overlapped, each solar module has a plurality of solar cells that are electrically connected in series with each other, with the serial connecting direction of the solar cells being set to a direction orthogonal to the ranging direction of the solar modules. Upon ranging these solar modules, one side portion of the solar module on the lower side on which a shadow of the solar module on the upper side is cast is formed into a non-power generation area by removing the solar cells therefrom.
