What Happens When You Connect Different Solar Panels In Parallel? Renogy - NewPowa - BougeRV

[@grindychum]

Rule of thumb I was taught; multiple panels in parallel- shoot for similar voltage. Multiple in series- shoot for similar Amps.

[@Jasonoid]

That's exactly what you want to do 👍

[@canalsentir]

Informative!! Thanks! 😊

[@mickeybrumfield764]

I would like to see how they do in series.

[@Jasonoid]

I think that would be a great video as well

[@PeaceChanel]

Thank You folks for All that you are doing for our Planet Earth.... Peace.. Shalom.. Salam.. Namaste 🙏🏻 😊 🌈 ✌ ☮ ❤

[@minceym]

Always learning something new from you. Thank you for all you do! 😊

[@Jasonoid]

I think it's fun to see how these experiments turn out.

[@minceym]

@@Jasonoid INDEED!

[@todd.parker]

Great test Jason. Very interesting to see the theory in action!

[@stuartstuart866]

Helpful video. It can be a bit frustrating to try and purchase an exactly matching panel, when even the same brand changes specifications.

[@Jasonoid]

Yeah, one year a company will have a specific voltage panel, and in a year it's been changed so you can't match your older panel.

[@DYT-jx4jp]

Thanks for your efforts and added moments of fun along the way!! 👍😂

[@OnusBones]

Interesting. I wonder where that power is going; perhaps heat from the diodes of the NewPowa panel?

[@Jasonoid]

That's a great question! I'm this case it was only 25 watts being lost, so not too horrible.

[@thom1218]

@@Jasonoid In bigger systems, that extra power bleeding off in components like diodes could make for dangerous hotspots that might lead to fire or premature failure of the weaker panels.

[@rwstarke]

I have 8 Newpowa 100W panels. I tested them on April 30, 2023 and saw 19.8 to 20.6 VOC in the Houston area.

[@Jasonoid]

This is their older 100w panel (short n' stubby model, 5BB vs the newer 9BB). Their newer panels have higher VOC.

[@skttnm]

This information is perfect as I've purchased two different sets of 100W panels, rigid and portable. The rigid ones will be semi-portable. With this info, I should be fine setting up 3 arrays of 400 watts each.

[@minutemanprep]

Cool test!🎉

[@Jasonoid]

Thanks! 😁

[@twloughlin]

Good luck with the consulting business! Priced right IMO.

[@Jasonoid]

Thanks for your feedback!

[@ZIlberbot]

would be also interesting if you connect them in series, what would be the result as for connecting them in series solar sun panel with the lowest voltage serves as a load for other two allowing current flow due to difference of voltages ....

[@StartVisit]

my two 100W Renogy panels mixed in parallel with another brand 200W panel, 22.76V at controller.

[@shelley131]

This was interesting. Now I am going to try my solar saga 100 from Jackery and one of my lynx panels from Inergy Apex 100W too. Just need to figure out how to do some adapters as one has the 8mm plug and the other has the EC8 plug. As always, you have great contents in your videos.

[@Jasonoid]

There are many more adapters available vs what there has been in the past. You should be able to find something that works!

[@Ethan.s..]

Can you also include a link for the “Cut Green Beans”, aka solar angle barometer?

[@Jasonoid]

😂🤣 I found this HUGE can! Haha amzn.to/3VlpE5F

[@DYT-jx4jp]

Yea, in a prior video he provided the specifics (e.g., brand, contents) to max solar alignment 🤣🤣

[@Ethan.s..]

@@Jasonoid thank you sir! Ha

[@eltonpereira875]

Connecting all 3 with a diode on each would make a difference?

[@marygallagher3428]

Interesting!

[@schadlarry]

I have the same NewPowa panel with the 9BB. The max I have seen using an inline wattmeter was 95 watts. Not bad for a $70/panel. I also noticed a world of difference with the panel tilt. Testing in the winter sun it dropped 40% lying the panel flat vs the optimal tilt of 45-50%. So in theory if you connected 3 NewPowa's you wouldn't have that much of a drop then.

[@Jasonoid]

Great info about the newer panel and it's output. I love the price of those ones! I paid near $100 for the renogy...

[@schadlarry]

@@Jasonoid Yeah, if I recall I was getting around 20V out of it too. For less than $20 in PVC and some hardware you can make adjustable legs for them.

[@jaysonstebbins2539]

I have 18, 100 watt panels on my ecoflow delta pro. 6S3P 10 renogy 24.3 VOC 2 renogy 21.8 VOC 4 HQST 20.4 VOC 2 HQST 21.8 VOC I mixed in the lower voltage panels to bring the VOC down to keep the MPPT safer from cloud edge effect in which jasonoid described in one of his videos which was a phenomenon that I wasn't aware of when running 6S2P all renogy 24.3VOC on my delta pro which is a 150VOC max input and 15.9 amp input max. On cloudy days I would see the input drop to 0 then back up to about 1450 watts on a 1200 watt array... so now with the lower voltage panels mixed in I see up to 1610 watts and about 135VOC and 115 V under load. the delta pro pulls the 15.9 amps and with overpaneling I get great results in low light conditions like overcast. Thanks Jason!

[@Jasonoid]

Great tactic to lower down the voltage to keep it within spec of the charge controller!

[@lesbollinger7099]

Interesting need to learn what all the different numbers and letters mean not a geek just a old guy tryin to learn have relied on your videos over the years thanks much

[@Jasonoid]

The most basic on you need to learn is this one: volts x amps = watts

[@myfpv6813]

I would love to see bigger diffrence in A between panel to test. Here we got 5; 5,5 ; 6A. But I wonder what would happen if we get a 5A panel and 10A panel together, will the power be really limited to 5A on each? Or there will be some average balance set? And same what will happen if we. Get a 20v and 30v panels together :) theory says one, but that kind of practical tests sometime give more interesting results :)

[@GrantSR]

I was surprised that the parallel voltage kind of averaged out. The common "wisdom" is that the voltage always drops to that of the lowest voltage panel. That is encouraging, because i need to buy a third panel to add to my existing two. If i buy a panel that is a little higher in voltage than the existing ones, then i can simply pretend that I have purchased a lower power panel for that same price and just call that good.

[@zenniz1992]

Connecting panels with different voltage rating in parallel is dangerous. There will be reverse current to the panels with the lowest voltage if the difference is huge, this will blow the fuse of the panel or damage it.

[@GrantSR]

@@zenniz1992 Well, I specifically said I wasn't planning to do that anyway. But, I get it. It is still important to warn novices to not go too far with things. Even if you are really just looking out for others who may read something later.

[@jasonbroom7147]

What the heck just happened? Why was there some other guy in your video, randomly presenting one aspect of it? Yeah, mismatched panels will always be brought down by their "weakest link".

[@DYT-jx4jp]

I think he is having some fun with his videos occasionally?? 🤣 I was like, who is this person? 🤣🤣

[@oscaranderson1822]

❤

[@michaelcyntchi8941]

What if you connect with panels of different wattage

[@zenniz1992]

Wattage doesn't matter, it is your voltage and current rating of the panels. Power (wattage) = voltage x current In series, final voltage = sum of output voltage of all panels. final current = lowest of the panels.

[@linkinanytime]

What happens when you connect in series mismatched panels?

[@Jasonoid]

In a series array, its all about the amperage of each panel. If you have similar amperage specs on all the of solar panels, the array will perform well. In parallel, you want all the voltages to match for the best performance.

[@scozilla8503]

Great videos! Can you specify what close voltages and amps are ?Less say a 21.8 volt panel and a 24 volt panel close enough? I have four of the same one hundred watt panels and considering buying 4 panels that are at least two volts higher but not much more. Amps slightly different as well. Any suggestions would be great. thank you.

[@robert4027]

i have 4 hqst 100 Watt panels. 19.8 open circut voltage and 4 9bb hqst 100 watt. 24.1 open circuit voltage... how should i wire these ..victron 100/50. charge controller is what i have. ???

[@chaon93]

The losses weren't too huge thanks to the fact that the VMP is simply the ideal voltage, As long as the lowest voltage panel's VOC is higher than the highest voltage panel's VMP, the panels will just shift around on their voltage/amperage curves. Nothing is producing at ideal levels, but everything is still within spec. Basically, Great = Identical panels, Good = Very similar voltage, Okay = VOC of low panel greater than VMP of high panel

[@richardhobbs7107]

Of course you let all panels get to the same temp. before doing these tests. So the Renogy's obvious superior output was not due to it's being the first one tested (at a cooler temp.) . . . . ? I do enjoy your videos = Thanks ! take care, rh

[@Jasonoid]

I let them sit out for about 2 hours before doing the video. They were all exposed to the sun for the same time period. Great question!
