The invention discloses an adjustable base for supporting a solar energy panel and an angular adjustment method thereof. The adjustable base comprises a frame, an angular adjustment element and a side bracket. At least one solar energy panel is fixed to the frame. The angular adjustment element arranged on the frame comprises an angular positioning element so as to provide a limited number of angular positions. The side bracket is connected with the frame via the angular adjustment element. The relative rotatin angle of the side bracket corresponding to one of the limited number of angular positions with respect to the frame is adjusted by the angular adjustmtent element. Therefore, the adjustable base can satisfy different requirements so as to fix the solar energy panel at different angles, which solve the problem that the sunlight utilization rate of a solar panel panel fixed at a single angle is low in the prior art.

The invention provides an all-weather photo-thermal photovoltaic integrated automatic control heat pipe water heater. The water heater comprises a solar water tank, a support, heat pipes, a thermoelectric generation module, a storage battery, a cold water circulation system and a controller which are mutually connected.
