<p>PROBLEM TO BE SOLVED: To provide a novel solar collector, capable of indirect collection of 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 having the solar cell module is provided with a bag-like body (6) made of a flexible sheet (61) and facing header pipes (7A) and (7B), disposed in parallel with facing sides (62A) and (62B) in the bag-like body (6). When heat is collected, one (7A) of the header pipes makes heating medium from the outside flow into the interior of the body (6) through a heat medium discharge port (73A), and the other (7B) of the header pipes makes the heating medium which is flowing in the interior of the body (6) from the opposite header pipe (7A) to flow into the pipe through a heat medium intake port (73B) and discharges the heating medium to the outside. The body (6) is inflated by the heating medium, flowing in from the opposite header pipe (7A), so as to be brought into close contact with the rear face of the solar cell module.</p> |
