Dual Axis Solar Tracker V2 - Arduino Powered - Open Source

Solar Tracker V2 is made made of laser cut wood, a whole bunch of screws, an Arduino Uno, two 9G sized Servos, and a custom Arduino shield. Get kits and parts from us or use our open source files to make your own.

Seriously, this is 100% Open Source. The code, laser cut files, and PCB files can be found below. Buying kits from us helps us buy equipment, go to teaching conferences, and spend more time making Open Source Projects.

i love this video, i came to it last night

[lolaloliepop]

oh finally this is so helpful. I plan on making one to make a heliostat for my dark apartment....looks like even just using this design I could somehow just strap a mirror to it where it doesn't fully block the panel

[adzjamros]

Thanks a lot. Mine use cardboard boxes and work like yours. Keep sharing!!!

After a some time of troubleshooting when I plug power into the board after downloading he program all it does is go invert and stays that way.

[Museincore]

Which LDR Sensor Shield did you use? I can't seem to find it.

[triyulianto]

whether this design can lead automatically to the sunrise the next day ?? because this design will stop at sunset.

Does anyone know of a version for an outdoor 100watt solar panel set up?

[rohitdama]

Really a good project but
What is the difference between dual axis solar tracking system & automatic solar tracking system using arduino

[polaezzat]

please, can you upload the design with its dimensions in an engineering program like solidworks or autocad

[Mlebanni]

Hello, I wanted to know if it is possible to know how much energy is produced by the panel, like can you have a number on your computer for example ?

[littleprincessdeekshu]

Please send me the diagram of the lazer cut chassis board

[alexmod]

Hello! Can you please tell me which servo motors are you using? Will the sg90 tower be enough?

[kaziimranahamedprotic]

will you please tell me. how did you guys take the value of dtime and tol ?

[sunilbute]

Very nice 🙏👍🙏 how can I use with it linear actuator, ? Is it possible to use with linear actuator?

[lukagobovic]

Hi. Do you have any info on solar cell like power, max voltage, max current? Or manufacturer of the cell? Thanks :)

[lewisnearker]

can someoneo help me with the code. the one i got from the website. it's not working properly.

[hieuphung]

Can you explain this code to me?




// int dtime = analogRead(4)/20; // read potentiometers
// int tol = analogRead(5)/4;
int dtime = 10;
int tol = 50;





This is the code I took from you. I don't understand much about this part
why tol is 50?
aint dtime=analogRead(4)/20; Why is 20?
Looking forward to your early feedback
Thank!!!

How long does it take to get the shipment to Mexico?

[tophbeifong]

I can't find the laser cut files in the link

[alexfurnies]

Someone can comment to me line by line this part of the code of what makes me not understand
if (-1*tol > dvert || dvert > tol)
{
if (avt > avd)
{
servov = ++servov;
if (servov > servovLimitHigh)
{
servov = servovLimitHigh;
}
}
else if (avt < avd)
{
servov= --servov;
if (servov < servovLimitLow)
{
servov = servovLimitLow;
}
}
vertical.write(servov);
}

if (-1*tol > dhoriz || dhoriz > tol)
{
if (avl > avr)
{
servoh = --servoh;
if (servoh < servohLimitLow)
{
servoh = servohLimitLow;
}
}
else if (avl < avr)
{
servoh = ++servoh;
if (servoh > servohLimitHigh)
{
servoh = servohLimitHigh;
}
}
else if (avl = avr)
{

}
horizontal.write(servoh);
}
delay(dtime);
