For small residential installations: A two-person lift or ladder slide is usually the simplest and most cost-effective option. As system size increases, this method becomes more difficult. Installing a smaller sized system means less panels; a 6kW system, for example, only includes about 15 panels. Carrying them up the ladder can also be done with products like the solar panel caddy, and all of these ideas will make this task that much easier. Petehimself of HBPowerwall fame mentioned in his live stream today something about having issues lifting PV panels onto the roof, so I thought I'd share "my" (*1) method. I use this to lift up 18kg panels onto my 3. RGC's new Platform Hoists are engineered for heavy-duty lifting, offering increased capacity and stability for solar installation teams. You can easily grip the solar panels with suction cups that. Items that are heavy, large, awkward in shape or awkward in weight need two or more people to lift.
