NOVELTY - A resin substrate solar cell module (100) comprises solar cells (102); support posts (104) disposed between the adjacent solar cells; and two transparent resin substrates (101), where the plural solar cells and the support posts are disposed between the two transparent resin substrates, a void section between the two transparent resin substrates is filled with a transparent filled resin (106), and peripheries of the two transparent resin substrates are welded with a resin having a repeating unit identical to the transparent resin substrates.    USE - As a resin substrate solar cell module (claimed).    ADVANTAGE - The resin substrate solar cell module prevents breakage such as cracking in a light-weight solar cell module; prevents breakage, sound insulation function, and lighting; prevents the warping of the module and the stress concentration at the sealed part coming along with the expansion of the transparent filled resin such as a silicone resin in the solar cell module making use of the resin substrate; is highly reliable, and excellent in flame resistance, weather resistance and stress characteristics; avoid the influence of warping of transparent resin substrates comprising polycarbonate caused by wind pressure and hailing by being supported with support poles; has high durability against wind and rain; and has good power generating characteristic even when an installation site is not necessarily a site being oriented to the south and has a good sunshine condition since crystalline silicon solar cells are bifacial solar cells. Since a partition wall (weld band) forming a resin inflow section is formed of polycarbonate, it is possible to grant durability also to the partition wall in spite of the fact that light-weight resin substrates are used.
