Hi, good day & welcome! 😊 🙏 ☕️

I am an electrical and renewable energy engineer working as CTO (chief tehcnology officer) of a solar company in Europe, managing mostly industrial & commercial Solar PV installations.

A part of me, being an educator by nature, simply couldn't bear the fact that so many DIYers are lacking proper technical knowledge which compromises the safety, endangering theirs lives, neighbour's and investments. These are the reason why I share my technical knowledge in renewable energy engineering, particularly regarding Solar PV System.

As an educator/mentor, I call my mentee/students, and followers "PADAWANS" taken from the Star Wars film... meaning a Jedi apprentice.

    Great informative video. Would there be any issue or problem with installing two DC SPDs for one solar string. One SPD in parallel with the disconnect switch in a combiner / disconnect box for the solar panels and another SPD at the end of a cable run in a pass through / disconnect box before the inverter. I am thinking if during an electrical storm if the first SPD gets disabled the redundant second SPD near the inverter might help to possibly save the inverter. Thank you.

    Thank you for sharing your knowledge JF, my question is do you recommend using hybrid all-in-one MPPT Solar Inverter? Because I noticed that based on your teachings and diagrams you are still using traditional system like individual parts for mppt and inverter. I believe that for DIYers hybrid all-in-one is much more easy to install than the traditional set-up.

    Panel 1, which is capable of producing 200 W at its maximum power point (MPP), is only producing approximately 165 W because it is forced to operate at the lower current. This results in a loss of potential power generation. The reason for the power discrepancy is due to the series connection limiting the current to the lowest panel's current rating (Panel 2 at 5.41 A). This forces Panel 1 to operate below its MPP, reducing its power output from 200 W to approximately 165 W. The excess power from Panel 1 is not "produced" because the panel is operating at a lower current than its optimal current. This is a common issue in series-connected PV arrays where mismatched panels (in terms of current rating) lead to suboptimal performance. The power output is inherently limited by the panel with the lowest current capacity, leading to the observed total power of 265 W instead of the combined rated power of 300 W.
