<p>PROBLEM TO BE SOLVED: To provide a novel solar collector capable of indirectly collecting heat from a solar cell module more efficiently and easily, and to provide a solar cell unit or system having the same. SOLUTION: The solar collector of a photovoltaic power generation unit with the solar cell module has a plurality of small bag-like bodies (6) disposed in parallel and made of a flexible sheet (61), an inflow header pipe (7A) in communication with one ends of the respective bag-like bodies (6), and an outflow header pipe (7B) in communication with the other ends of the bodies (6) facing the one ends. The inflow header pipe (7A) and the outflow header pipe (7B) are disposed facing each other with the respective bodies (6) which are placed between them; when solar heat is collected, the inflow header pipe (7A) makes a heating medium flow from the one end into the respective bodies (6) and the outflow header pipe (7B) takes in via the other ends into the pipe itself, the heating medium which is flowing through the bodies (6) to cause the heating medium to be discharged to the outside. With such a constitution, the respective bodies (6) are swollen due to the heating medium to be brought into close contact with the rear face of the solar cell module.</p> |
