SOLAR POWER PART 2
Video of my Solar Tracker
By tilting the panels down reduce the force by 80%
Before adjust for high wind
The wind is my enemy
Strong wind can easily create the force that destroy my solar-project. So i think i must have a solution for this. I have done some test and found out that if i tilt the solar-panels down to 15 degrees and 10 degrees off the wind direction the force to the solar-panels goes down by 80%. But how to do it? I recently got in contact with Dougal Plummer a guy that has his own Solar-park and he has done several project and programming in controlling the movement and track the sun. He is marvellous in programming.
How to make Altitude movement ?
There is Linear actuators out there to buy but they are to weak, i think. So i got a M30 tread bar for 10USD at Biltema, one meter long and weight 4 kg.
I will make my own Heavy Duty linear motor with a DC motor with a worm gearbox.
After seeing what can happens in strong wind i decided to make the Solar Tracker more stable by adding a mesh at the back. Se the movie.
Altitude South - North
A linear motor should do the job. But i could not find any strong enough for the purouse so i will make one myself from a M30 tread bar and a worm gear motor. The WormGear motor speed is 440rpm. That will turn the M30 bar 2,5mm/rpm = 1100mm per minut. That will be a fine speed to move the Solarpanels with a lot of torque.
