The X Axis aka Horizontal Axis

14th August 2012 - The build

Linear Actuator Solar Tracker
These are the parts used to create the x-axis.
1 x Linear Actuator - approx 40
2 x Mounting Brackets - came with the Actuator
1 x Threaded Rod - 2 from B&Q

The bottom mounting bracket. Drill two holes through the post and bolt. Simples!

You need to do some thinking here and work out the where you need to position the top bracket. The closer to the fulcrum, the greater the swing achieved, but you'll also increase the stress load on the actuator. I've mounted my bracket to give approx 80° swing. It doesn't quite achieve full horizontal, but as England isn't in the tropics, the sun never gets directly overhead, so I don't need it to achieve 90°

Here is a video demonstrating the x-axis. I'm powering it with an 18 Volt drill battery, which makes it move way too fast. I reckon I'll probably put 5 Volt to it when done.

Gokulesh - Yes, I suspect things might get a little twitchy, but I hope to fix this with some thresholds set in the Arduino code. Obviously still yet to be tested, but I'm hopeful!

Understood :) ... You'll rotate using vertical axis to go other side... but i think motors will be very twitchy during noon transit...

how it'll rotate other 90deg rotation? (you have rotated only to one half ri8?)

I'm not too sure. I plan on only using two panels cos that's all I need. But I reckon it could probably do double that.

Do you have any idea how much load it could take? ie, how many solar panels?
