[Title: solar collectors, solar panels and building heating processes with integrated heat storage.The invention relates to a solar collector (4), which comprises a tube (40) extending from an upper end (41) of an opening to a second lower end (42) corresponding to a closed bottom,The tube (40) has a double wall, the first wall forms a cylindrical cavity (43) and defines a heat absorber, the second wall surrounds the first wall and defines a solar collector (4),The second wall connects the first wall at the upper end (41) of the tube (40) and extends parallel to the first wall between the two ends (41, 42) of the tube (40), forming a cylindrical gap between the two walls, which is in a vacuum state, The utility model is characterized in that the upper end (41) of the tube (40) is closed by a sealing plug (5), which allows the heat absorber to contain hot fluid,The cover (5) extends from the base (50) of the upper end (41) of the support tube (40) to at least one free end (51), which is configured to extend into the heat exchanger so that the cover (5) transmits the heat energy stored by the hot fluid to the exchanger hot.The invention also relates to a solar heat plate (1), which comprises a solar collector (4) and a method for heating a building integrated with the collector.Abstract figure: Figure 1]
