## Abstract

A solar thermal collector is disclosed. The solar thermal collector has side surfaces and a bottom supported by a support frame shaped into a square shifter and installed tilted on a rooftop of a building by means of a plurality of angle connections. The solar thermal collector includes a reverse bias circuit. The top of a lower surface of the support frame is level with a tilted surface of the solar thermal collector or the support frame includes a tilted surface tiled downward, which is formed along a horizontal direction, lower than the surface of the solar thermal collector.
