I gave up. The mod is totally broke the stock parts. When I tried to select the parts for elimination I did not know which part is really belongs to original Squad, and not the Ven's mod. I try to delete lines from CFG-s but it did not helped at all. Sometimes I just got gray box models instead of the original. Then I deleted all the part folders in the Ven's mod folder except Squad/Electrical. I deleted the Path cfg-s too (except the electrical). The original Squad items disappear or they get the gray box model (science stuffs, docking ports, antennas, etc.). This radical method is working on the other mods This mod is just too complex for me. I think I should love the original solar panel textures. Thank you for the help
