The Winlet product line has been used for glass and window installation for many years, allowing extremely heavy window elements to be lifted, transported, and installed easily. Most recently, the engineers at Winlet have worked with solar power professionals to develop a track-based Winlet, capable of meeting the requirements for solar panel installation. This Winlet technology increases efficiency and speed in solar panel installation and transportation, while improving safety in the workplace. The Winlet features four suction cups, which will hold up to 1320 pounds of material. The Winlet is also self-propelled, and can access narrow doorways, elevators, and balconies. It also features tracks for rough terrain operation.
