Share My Creation cheap solar panel system (solar tracker + MPPT charger)

Hi all,

It's quite a long time since I posted something in this section ...

Here is my latest creation, it's a cheap solar panel that I have mounted on a solar tracker system.
Added to this is a MPPT controller which is itself controlled by a B4A app 👍

It allows, data logging and command/control of the controller (nothing fancy but works !)

System running under France's sun :




Everything is submitted to the Hackaday's "Planet friendly-Power" challenge. You can find a rather detailed description here : https://hackaday.io/project/185105-low-cost-solar-panel-solution-mppt-sun-tracker

DONE : Within 15 days I will know if selected for the second round or not ;)
BTW, don't hesitate to like the project on hackaday it may help for final selection (as I am already finalist of this prize !), who knows ?

[edit] : source code is here : source code

[edit] : companion App to "find the sun" is
available here (see this post for details)

Have fun with B4X

Thanks for this amazing work.. Not quite sure but I thought maybe a telescopic linear actuator be more easier control thank the stepper of servo motor operated, but it may need a lot of app changes.

BTW, the leadscrew is already a linear actuator (but DIY !)
Your proposal should work with very little code modifcation.

Hi all,

As promized here is the source code for both the B4x App and the ESP32 MPPT charge controller : https://github.com/f2knpw/ESP32_MPPT_solar_panel_controller

More details on the ESP32 code here : hackadays

Detailled description for the B4X App will come soon, but I am sure that you don't need it on this forum !
The zip file is on the github repo : B4A app

Don't hesitate to follow and like the project on hackaday as it is now selected among the ten finalists !
I must say that thanks to this great B4X community I already won 500$ prize :)

By the Way I did publish another project but with "no code" for another challenge --> follow and like it if you wish : pullstruder-from-plastic-bottle-to-pet-filament

I have just added a simple App to find right orientation of the panel.
It should work with any solar pointing device.
There is a simple compass to rotate until the "sun logo" is aligned with the blue line
Same thing for the Elevation angle

Needs location permission to work

based on animation library, FusedLocationProvider (@warwound ) and sunAngles (@derez Astrolib)
