Photovoltaic solar collector and use method thereof

The invention discloses a photovoltaic solar collector and a use method thereof, and relates to the technical field of solar collectors, a rectangular frame is arranged above the top surface of a chassis, a pair of side plates are fixedly arranged at the rear corners of the two side edges of the rectangular frame, a plurality of translation plates are arranged between the opposite surfaces of the pair of side plates, and fixed lug seats are fixedly arranged in the middles of the bottom surfaces of the translation plates; a fixing shaft is arranged in the middle of the fixing lug seat, and a solar panel is fixedly arranged at the front end of the fixing shaft. The solar panels can be adjusted leftwards, rightwards, forwards and backwards in all directions, the solar panels can be folded and stored under the condition that weather changes are complex, circulating water is heated when flowing through a pair of heating pipes through use of the heating and ventilation mechanism, then the whole solar panels are kep
