The patch off is not a fair comparison for both. You need to check the orientation of the series and parallel connection of the individual cells on the panel. It's likely not identical
I have always known this about Mono and Poly, Poly are very efficient in places like Northern part of the country where the sun intensity is crazy. Areas like Lagos, just stick with Mono.
@smilinsun Correct, but it's not a bad idea as long as they are in parallel connection. I will not recommend the series connection for obvious reasons. When they are in parallel, 220AH battery gets to full charge first because they are in parallel connection and the 230AH will also get to almost full charge. Let's say 225AH storage or even 230AH depending on the charging parameter or inverter. Let's be theoretical here. Let's say the first battery is 10 ohms resistance connected in paraale to 11 ohms resistance (Second battery). The total or effective resistance is (10 x 11)/(10+ 11) = 5.23 ohms. Voltage drop increases with increase in resistance. This is why the voltage on the battery increases as current flows through the battery thereby increasing the battery internal resistance. Charging voltage increases by the increase in battery internal resistance. Full charging voltage is determined by the inverter as a result of the expected internal battery resistance which determines the charging absorption voltage. Another way to look at it is because the 2 batteries are in parallel. Using ohms law, the same voltage will be across both batteries, but the charging current will be different based on different internal resistances. This will continue until the resistance to stop charging current flow is reached for both batteries. Inversely when discharging, more current is discharged from the battery with lesser resistance (230AH Battery) then the low battery protection is reached when the resultant resistance for low battery protection is reached for both batteries. When the storage capacity (Amperage) for both batteries is wide, it is practically not encouraged. 230AH and 220AH in parallel is not totally a bad idea if there is no option of using the same battery amperage and brand. However, this is not a yardstick or a culture to begin to mix different batteries of the same amperage or different battery amperage of the same brand. My humble submission. Good job@smilinsun
All vedios your are intresting
Thank you Sir
Wow loving thr video
Thanks
Very interesting fight
Thanks for watching
nice please do a comparation btw halfcut panel and none halfcut panel
Thanks for the insightful information and awareness.
I love this ❤️❤️❤️❤️
Thanks
Just a proof point out my points nw … thanks for the video ❤
Glad you enjoyed it
You're doing great work
Thanks for watching
Thanks for this information
Thanks for watching
From what I see here buying a poly is 200%
@@HappyWinging Lol
Well done.....Can we have Monofacial vs bifacial panel
Ok will do Thanks for watching

Lol very incorrect insight
Great review as always.
Please check your title. You wrote poly vs poly.
Oh wow Thank you so much didn't even notice that.

Yeah Poly pulls in great energy all the time , Mono is so highly overrated
I was surprised also with mine making 5-10% power over my monocrystalline, but the opposite happens in lowlight and shading where the mono always win.
Thanks for educating us always, sir I have two batteries of 220ah and 230ah. Both in 12V, hope it's not bad using them together?
Batteries of different amperages should not be used together

Good job@smilinsun
Thanks for the text, but a bit complicated...
How do you mean, would love to simplify
@@smilinsunsmilinsun8056 To me I prefer the monocrystaline...
My Judgement Is that Mono has slightly won the battle.
Not scientific enough. Brand? Voc, isc, etc?
What about the tilting angle position?.....Are they at 15degree?
Yes
Its MONO for Me.
Good Choice Buddy!!
African weather is special 😂
We are very Blessed
