Modular System for Cleaning Solar Panels

A modular system (1) for cleaning panels or arrays of panels (100), wherein it comprises:

• at least two independent modules communicating with each other, arranged at the upper and lower ends of the array of panels (100), respectively, thus forming an upper module (10a) and a lower module (10b);
• and
• at least one cleaning element (16) disposed transversely to the array of panels (100) between the at least two upper and lower modules (10a, 10b), wherein said at least one cleaning element is attached to said upper and lower modules (10a, 10b) by means of couplings (17);
• wherein each of the upper and lower modules (10a, 10b) comprises at least one traction element (14) arranged perpendicular to the array of panels (100), wherein said traction element (14) rotates when a force is applied, providing in this way movement to the upper and lower modules (10a, 10b) through the array of panels (100).
