PURPOSE:To utilize the incident sunlight effectively by arranging plural pieces of solar cells connected in series in a parallel direction with a ledge member. CONSTITUTION:Plural pieces of solar cells 2 are set up in a long base material 1 in lineup form. Then these solar cells 2 set up in parallel with each position of ledge members are connected to one another in series by wiring conductors 3. In addition, these solar cells 2 set up in a direction orthogonal with each position of the ledge members are connected in parallel by another wiring conductor 4. With this constitution, a shadow of the ledge 5 is cast on each of the solar cells 2, so that any possible drop in output is held back to the minimum. |
