Energy-saving Solar Panel

Abstract

Disclosed is an energy-saving hollow sheet whose spacing bars between the multiple panels are totally canceled; whose positions of screw hole have cylinders of certain thickness mounted by directly moulding, gluing, assembling, etc.; whose panels have frame at their brim; whose panels' distances and positions to each other are fixed by the above cylinders and frames with the distances between the panels controllable and the number of panel layers addable thereby, resulting in a thermal insulating performance able to reach any level; whose cancel of the spacing bars can bring a transparency same to glass curtain walls.

1 . An energy-saving hollow sheet whose spacing bars between the multiple panels are totally canceled; whose positions of screw hole have cylinders of certain thickness mounted by directly moulding, gluing, assembling, etc.; whose panels have frame at their brim; whose panels' distances and positions to each other are fixed by the above cylinders and frames with the distances between the panels controllable and the number of panel layers addable thereby, resulting in a thermal insulating performance able to reach any level; whose cancel of the spacing bars can bring a transparency same to glass curtain walls. 
     
     
         2 . The energy-saving hollow sheet according to  claim 1 , wherein the spacing bars and the insulating structures are combined: at the outer layers the cavities have spacing bars so as to keep the structural strength; at the inner layers the cavities have no spacing bar so as to bring the insulating function; the numbers of outer layers for structural strength and that of the inner layers for insulation function can be adjusted according to the specific requirements on strength and insulation. 
     
     
         3 . The energy-saving hollow sheet according to  claim 1 , wherein a rain cover is set between two hollow sheets in left-and-right connection: the rain cover is fixed to the building's frame with sufficient space at the inner side of rain cover for expansion of the hollow sheets; at the edge of the hollow sheets there are set rain-proofing plates to prevent the rain from entering the space between the hollow sheets; at the lower brim of the upper rain cover there is set a covering plate to cover the upper brim of the lower rain cover. 
     
     
         4 . The energy-saving hollow sheet according to  claim 1 , wherein the bolt hole has a rain-proofing ring: the diameter at the bottom of the rain-proofing ring is smaller than at its top, so as to prevent the rain from surpassing the rain-proofing ring. 
     
     
         5 . The energy-saving hollow sheet according to  claim 1 , which can be used in a multiple-storey building: the floors of the building have insulating blocks with a rain-proofing plate and a covering plate respectively set at the top and bottom of the insulating block; at the same time, the hollow sheet above the floor has a covering plate set near its lower side, which covering plate has an elastic lower brim with a height lower than the top of the rain-proofing plate on the insulating block; during installation of the hollow sheet, when it is being pushed outward, the lower brim of its covering plate surpasses the top of the rain-proofing plate on the insulating block and then restores its original shape, so as to prevent the rain from entering the space between the hollow sheet and the insulating block; also, the bottom of the rigid part of the hollow sheet's covering plate is set slanting outward, so is the top of the insulating block set, thus further improving their rain-proofing fun
