Hi guys I have had a bee in my bonnet about making my own tracking solar panels for a few years now, and a few weeks back decided to give it a go. Basically because of where mine are, either side of the sat dish, I need to make them slide out either side of the RV before elevating and rotating. I have made a frame that goes the full width of the RV with two sliding frames either side, mounted a lazy susan onto it which will be driven by window winder motor, both the sliding frame and the elevation will be achieved with electric actuators. Now an immediate problem is the drive between the motor and the lazy susan, I have tried nylon cord but it slips to much, next idea is 1mm galvanised wire rope, as it has a rough surface, but open to other ideas. I also need a source of cheap 12v actuators minimum 12" extension and 100kg push.
