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.
