The final entry showcases a design improvement that allows the use of existing bottles on roofs. To install, simply remove the cap, drill a small hole, and add new components. The transparent LED bulb cover and ON/OFF light cord remain featured. Notably, this system is compatible with all roof types, requiring only one hole and screw for mounting. The light cord is routed through the screw pole to the house's interior, featuring a rubber sealing ring for water prevention. A new aspect is the ability to adjust solar panel placement post-installation using a knuckle joint, ensuring optimal positioning. Despite having three additional parts and a joint, the solar-panel/battery unit is considered a single box due to increased flexibility. The bottom battery unit can be mounted between grooves with minimal fuss, thanks to its compact size and fixation via one screw within groove dimensions no longer being a concern.
