In this video the test set-up for the C2000 MPPT prototype is shown, with a 10W polycrystalline solar panel, connected to the prototype PCB. This was used for testing and tuning the Perturb & Observe algorithm. A full tutorial covering the electronics and C code can be found at my website Coder-Tronics.com by following the links below.
If you like the video and the tutorial please give it a thumbs up and support the site.
There is also an additional video which shows the tracking algorithm in operation, with the PV Power, PV Volts and Duty Cycle variables being graphed in Texas Instruments Code Composer Studio.
