Abstract
Abstract The solar-exposed cover portion of conventional solar panel boxes are subject to variation depending upon customer choice, cost, heat insulation requirements and other factors, whereas the interiors of the boxes are standard. Thus, the cover portion may be a panel of plastic, or glass, or a combination of glass and plastic of varying thicknesses. The interior has a thick bed of insulation, headers and tubes all surrounded by a frame. Two different retainers are provided which may be attached around the side edges of the frame and used individually or in combination to accommodate plastic panels, glass or a combination of glass and plastic sheeting. The connecting pipes from the headers to the exterior of the box are provided with seals. By removing the retainers, seals and glass and/or plastic, the headers and tubes may be lifted out of the box for repair or replacement without removing the box.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
213 words
A solar panel construction comprising an open top box, said box having sheet metal sides, each said side having an inturned top flange, said side and flange coinciding at a corner, said box being open inward of the inner termini of said flanges; a first cover for the open top of said box; first retaining means for said first cover, said first retaining means having a first base having a flat bottom supported by said flange, a down-turned first outer edge extending outside said corner and engaging said side adjacent said corner, an upturned rim extending from said first base inward of said first outer edge, an upward-extending first offset inward of said first base, a first inner edge inward of said first offset engaging said first cover and securing said first cover against said flange, a second cover above said first cover, the margins of said second cover resting on said upward offset; second retaining means for said second cover, said second retaining means having a second base resting partially on said first rim and partially on said first offset, a downturned second outer edge engaging the outside of said rim, and an upward-extending second offset engaging said second cover; and securing means securing said second retaining means and said flange together.
Claim 2
Dependent Claim
213 words
A solar panel construction comprising an open top box, said box having sheet metal sides, each said side having an inturned top flange, said side and flange coinciding at a corner, said box being open inward of the inner termini of said flanges; a first cover for the open top of said box; first retaining means for said first cover, said first retaining means having a first base having a flat bottom supported by said flange, a down-turned first outer edge extending outside said corner and engaging said side adjacent said corner, an upturned rim extending from said first base inward of said first outer edge, an upward-extending first offset inward of said first base, a first inner edge inward of said first offset engaging said first cover and securing said first cover against said flange, a second cover above said first cover, the margins of said second cover resting on said upward offset; second retaining means for said second cover, said second retaining means having a second base resting partially on said first rim and partially on said first offset, a downturned second outer edge engaging the outside of said rim, and an upward-extending second offset engaging said second cover; and securing means securing said second retaining means and said flange together.
