Roof light

To create a solar-powered setup, I cut the tops off two cola bottles for a watertight seal and increased sunlight exposure. PVC pipes drain rainwater and house diodes, all glued together for waterproofing. A roof joint sealer surrounds a hole, followed by assembling components and tightening bolts to secure the setup. Finally, the cell cover is sealed with joint sealant; the lower bottle is filled with water prior to assembly.
