Little "rule of thumb":

The series connection makes so much sense !... great video Amy

Thank you so much for explaining these things! I've been searching for these answers for months and you're showing me exactly what i need to do for my situation! Best on youtube!!!!!

these are gr8 video tutorials which I start watching these few days, thanks alot- RAHKAR Green from Afghanistan

Great explanation, thanks! Would you be able to test solar panels in series (as per your last test) and then cover up one panel to see if the performance is still ok?

Excellent and professional demo of set up...loving this "series" you are doing! hahaaa!

How this setup works with 12v panels but 1- 200w; 1-100w with a PWM charge controller, any help will be appreciated, again thanks.

Very clever lady, thanks for this explanation 👌

i love all of your videos. much more detailed and informative than tbe rest.

What kind of monster actually puts a thumbs down on these videos..

I am curious of a side by side comparison to panels wired in series to increase amps and then single panels hooked to multiple charge controllers and the controllers wired in parallel. We know wiring controllers in parallel will increase amps but do you have more loss of efficiency?

This implies the more panels of any sort you have in series is good. But what about the higher and higher voltage you would get, frying the MPPT charge controller?

What will be better in my case is 8 440 watts in series or 9 panels in series-parallel, because 450v is my maximum of inverter panel has a 52 VOC and 4500 wattage

I have 3 solar world 60 cell panels, 290 watt. I want to install 6 canadian solar 315 watt in parallel with the 3 290 watts panels. The voltage, amps are very closely the same. I know that the the system is going to work at the lowest rate, but is any additional info to consider for this combination??

I'm enjoying leaning from these test rigs and I always have a go at guessing in advance which arrangement will result in the highest MPPT power output. Really educational videos; thanks Amy (and team)!

Hi just found you channel. I have 2 /100 watts panels one is 21.8 V the other is 19.83V . My question is ... will this make that much of a difference to no run the parallel. I was told that this might cause my MPPT controller to over charge my batteries

Thanks for sharing this information....it's very useful. I have a question, can you charge a single 12v battery with a 300w solar panel with a voltage rating of 36v?

Heard your comment about separate charge controllers for the different panels as an option... how does such an arrangement feed into say a 12v battery bank. I'm a novice.

Did you happen to try the series the other way, if you had the neg from the big panel going to the controller instead use the pos?

This helped a lot! Thanks! Would it be too much to combine a 36V 50W panel with a 12V 200W one?
