- I,- A foldable parasol , comprising: a top surface comprising a plurality of rigid surfaces , each comprising at 5 least one solar cell fixed thereto; and at least one mechanical hinge disposed between each adjacent two rigid surfaces , for allowing folding one rigid surface in relation to the other, the at least one mechanical hinge comprising an electrical conductor, for electrically conducting between poles of solar 10 cells of the adjacent rigid surfaces , thereby electrical conduction between solar cells of different rigid surfaces is applied through mechanical hinges , being durable to folding. |
