Thanks man, think I got it now

Next Problem, since the rotational speed for tracking the sun is extremely low, average is 0.000694 rpm, and using a motor of 110 W, the torque experienced on my shaft is impossibly high. Note, this has nothing to do with the wind load, just power delivered to the shaft by the motor and gears...

http://groundup.org.za/article/renewable-energy-streetlights-could-change-lives_1874 Think I stuffed up with the square brackets. Thanks everyone for the help today but I'm outta here. Will let you know what the final outcome is.

I'll speak to my lecturer about the wind speed but we were required to adhere to the standards. If you have a look at the "Twerly Street Light" [http://groundup.org.za/article/renewable-energy-streetlights-could-change-lives_1874] , which was designed in my city, it was also designed for 300...

Haha I questioned this myself when I first took a look at the standards. Then contacted a peer that is busy designing a parabolic reflector, he too used a wind speed of ± 300km/h

Shot boet

Aah Titus, so that was your post? You manage at all?

Haha thanks for the help guys. Hopefully I come up with a solution that makes some sort of sense.

Ultimately what this boils down to is the selection of a suitable motor; however the torque provided by low speed, high torque motors I've found on the net aren't sufficient. I have a suspicion that other post about the solar panel may be one of my peers. He/She seems to have gotten stuck at...

I will check it out. The 300km/h wind is due to South African standards [SANS 10160-3: Structural Design for Wind]

Thanks. Having done that, I get a torque of 1450,158 [N.m]. Surely it can't be that much? Would the motor for that torque not need to be huge?

< Mentor Note -- thread moved to HH from the technical engineering forums, so no HH Template is shown > I'm busy designing a solar panel mount for a 300W solar panel, roughly 2m x 1m in size and 30kg in mass. I would like to know how to calculate the torque on the shaft (situated in the centre...
