    How do I stick the panel onto the shaft so it can rotate ?

    hi weiszed, I already used epoxy to stick the shaft. I'll post some pics once i get everything up. Thanks anyway.

    How do I stick the panel onto the shaft so it can rotate ?

    The first pic is the behind of the solar panel showing the perspex that I attached to it. The second pic was a bit confusing, here are some new pics to demonstrate what i want it to be like. (Of course, my hand is just there to hold it in place) Is this still unbalanced ? Anyone else have any...

    How do I stick the panel onto the shaft so it can rotate ?

    Hi Q, here are some pics, the first shows the frame behind the panel and the second shows the shaft. So how do I apply the epoxy ? Only in between the shaft and perspex (only on the surfaces touching each other) or should I put like blobs which cover the shaft, and then the bottom will be...

    How do I stick the panel onto the shaft so it can rotate ?

    So if I place epoxy along the shaft and stick it to the perspex, it will stick well ? Because the shaft is only 5mm in diameter and the surface area exposed to stick with is quite small. I hope you get what i mean. edit: or can i place a blob epoxy over the whole shaft and then the perspex...

    How do I stick the panel onto the shaft so it can rotate ?

    The motor shaft is connected to another shaft A with a coupling. Shaft A is where I want to place the panel so that it can rotate. How can I do that ?

    How do I stick the panel onto the shaft so it can rotate ?

    yes, there is a perspex frame and the shaft has a diameter of around 5mm.

    How do I stick the panel onto the shaft so it can rotate ?

    Guys, Need some help urgently! I have a thin shaft and a rectangular solar panel. The shaft is connected to a motor shaft and will rotate. How do I stick the panel onto the shaft so it can rotate ? The simpler the solution the better.. Thank you everyone

    How Do I Design a 2-Axis Solar Tracker Mechanism?

    Yea, with the servo I can just attach it to the shaft without worrying about the gears, etc. Any idea how I should attach the servo shaft to the big shaft behind the panel ?

    Estimating Torque for Solar Panel-Powered Servo Motor

    How tiny ? The panel weighs 0.8kg. Is this servo sufficient (3.40 kg-cm torque) ? http://www.databitz.com/Resources/crservo.pdf What about the servo at the bottom (there will be some bearings below the base) ? It seems like the top would be a bit heavy. The whole frame will be made of perspex.

    How Do I Design a 2-Axis Solar Tracker Mechanism?

    I've been thinking of a simpler structure (see attachment) if I decide to use servo motors instead. Any comments ? The round base would probably be made smaller.

    Estimating Torque for Solar Panel-Powered Servo Motor

    I would need the servo shaft to rotate a total of 135 degrees, rotating a few degrees every half an hour for eight hours (It will operate like a stepper, stepping during each hour). The speed of rotation is not important, as long as it rotates. The panel's length is 32cm and height is 18 cm. It...

    Estimating Torque for Solar Panel-Powered Servo Motor

    Guys, I have a solar panel screwed onto a shaft which connects directly to a servo motor shaft. How much should the torque rating of the servo be to be able to rotate it ? I mean an estimate of the minimum torque required. The panel weighs 0.8kg plus a few grams for the solar panel holder (made...
