Support connector, solar panel connector attachable to the support connector, and attaching system comprising said support connector and said solar panel connector

A support connector configured for attachment to a support, the support connector comprising:

• an essentially U-shaped profile having a horizontal lower wall and two parallel vertical side walls,
• wherein an upper end of the parallel side walls is bent inwards to provide vertical rails for slidably receiving a solar panel connector;
• wherein the vertical rail comprises a downward projection for blocking the sliding movement of the panel connector;
• wherein the downward projection is located in a longitudinally central portion of the vertical rail;
• wherein the vertical rail further comprises a downward protruding, upwardly elastic portion located at a longitudinally end portion of the support connector,
• wherein a lower edge of the downward protruding, upwardly elastic portion forms a downward slope with respect to the horizontal lower edge of the vertical rail such that the downward protruding, upwardly elastic portion is first displaced upwards by a lower horizontal wall of the lower channel portion of the panel connector and then enters a first hole of said solar panel connector when said solar panel connector reaches an inner position.
