A solar cell array is formed by connecting an n-type electrode of a first solar cell included in a plurality of solar cells and a p-type electrode of a second solar cell with each other. An n-type electrode of a protective diode is connected to the p-type electrode of the first solar cell, while a p-type electrode of the protective diode is connected to the p-type electrode of the second solar cell. According to this structure, a solar cell array capable of reducing the number of welded points with respect to bonded portions of the solar cells as well as a process time and a solar cell module including the same can be provided.
