VIDEO DESCRIPTION:
I often receive queries regarding which connection of solar panels is the most efficient. Is it parallel, series connection, or a combination of series and parallel? The second question is, is it possible to use solar panels with different power ratings or specifications in one array or connection? What would be the outcome?
So in this video, I discussed just that and made some example calculations of different solar panel connections, including mismatched solar panels with different specifications.
So long my young Padawans. Blessings!

SOMETHING TO MEDITATE:
Galatians 6:7-8
Be not deceived; God is not mocked: for whatsoever a man soweth, that shall he also reap.
Proverbs 3:27
Withhold not good from them to whom it is due, when it is in the power of thine hand to do it.
Philippians 4:8
Finally, brethren, whatsoever things are true, whatsoever things are honest, whatsoever things are just, whatsoever things are pure, whatsoever things are lovely, whatsoever things are of good report; if there be any virtue, and if there be any praise, think on these things.

sir JF pag 10kwp po ba ung Solar Panel setup, kailangan 10kw din ung capacity inverter na bibilihin kahit mas mababa sa 10kw ung peak consumption? Di ko kasi sigurado kung sa solar panel capacity or sa demand ba magbabase ng inverter selection
New subs sir,a
Question lang sir
May
50w na 18.1v / 2.76a
+
30w na 18v / 1.66a
= 51.34 watts from 80watts (67% loss)
Tama sir?
Question sir what can I do para maging 80w output nya sir? Need ba isang controller pa?

salamat po sir sa ibinabahagi mong ka alaman napakalaking tulong po ang ginagawa mo
Wala pong anuman 😊🙏☕️
ito un hinahanap na calculation ditalyado lahat tnx sir
Wala pong anuman 😊👍
Thank you sir
ang solution sa magkaiba na size ng PV ay gumamit ng blocking diod ito ay pwede lang kung ang PV mo ay magkalapit ng voltahe (VMP) 50w to 200w d masyado mag babawas sa Imp tataas ang harvest so pwede natin pagsamahin ang 160w at 100w pv sa iisang SCC ng d masyado mababawasan ang A sa V sya mag babawas ng around 0.7v per panel so kung nasa 18v magiging 17.3v x ung pinagsamang Imp (A) pag 300+ na ung PV D na pwede kasi malayo na masyado ung voltahe mas ok na mag add nalang new SCC at dun ilagay ung mataas
Subukan nyo sa actual, i-vlog nyo at kung maari ay ibahagi mo sa amin para naman matuto din kami. 😊👍
good job more power po

Good day. 😊👋
salamat sir
Wala pong anuman 😊👍
Maraming salamat sir sa video nyo now we know how to compute different solar panel wattage, hindi kasi maiiwasan kung mag upgrade ka tapos hirap humanap ng ganong solar panel na kagaya ng dati at kung wala ka na mabili ng ganoon.Sir meron lang ako napuna tungkol sa 200 watts specs niya na Imp 5.36A ang nailalagay nyo po 6.56A pero konti lang po ang difference nila.
Good day. Wala pong anuman. Tungkol sa 200W solar panel specs na napuna ninyo. Hindi lahat ng 100W, 200W, 300W, 400, 500W ay magkakapareho ang specs. Iba ibang manufacturer, iba iba din po yan.
Napakalinaw po sir jf salamat po
😊👍
to be safe, same specs at wattage nalang sir noh para less hassle. As always very helpful tutorial sir!!!
Yes, tama 😊👍
pang dj ang voice mo sir,,heheeeh salamat sa tips

Nd nkakasawa sir JF Legaspi kahit paulit ulit kong pinapanuod for mastery...
Pinakamaganda Parallel lang.
ayos klarong klaro
😊👍
Sir maganda yung Tinuro mo sana patuloy mo lang sir.
😊👍
Sir jf salamat sa good tutorial., ask ko din po paano palakasin ang charging sa solar battery.
Gumamit kayo ng MPPT SCC na may mataas na efficiency rate. 😊👍
Good day Sir JF. Helpful and informative ang video nyo as always. Ask ko lang po if also possible to connect in parallel ang two toroidal off-grid inverters with the same model (not hybrid)? Maraming salamat for providing as education in a well organized and comprehensible manner. Mabuhay po kayo.
Good day. Kung sa DC side/supply ng dalawang toroidal inverters, pwede. Depende na lang sa C-rate ng battery kung kakayanin ang hugot ng dalawang inverters.
Pero kung sa AC side/output, hindi pupwede. Puputok kapag ginawa nyong parallel ang dalawang inverters.
Pwede ba e series Ang panel.3psc 450watts at 1pcs 120watts?
Sir paarbor digital mulyitester.. hehe😂😂😂
Sir love this content po dagdag kaalaman sakin to, tanong lang po since magkakaibang Panels po ang gamit Pano po kung separate SCC sila tas isang battery lang(Off-Grid). thank you sir
Good day. Pwede po 😊👍
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.
Thank you sir . Malaki tulong ito sa mga bagohan.
Para mas safe same specs nlng talaga gamitin or gumamit nlng nang isa pang SCC if gusto mag dagdag nang panel with lower specs. Tama po ba sir?
Tama po.
Sir Jf..medyo nagogolo pa Po Ako.. salamat Po sa vedio online classes Po. God bless

Hi sir. Pwd po makabili ng scc mppt nyo ung low prof lang po at lowprice😀😀😀 NB lang po s solar diy maraming slamat po sir jf legaspi.. more vlog pa po.. pra maraming matutunan...
Good day. Wala pa po akong shop dyan sa Pilipinas, paumanhin. 😊🙏
@@JFLegaspi ah akala ko po nsa phillipines po kau.. hehe slamat po. More blog pa po sobrang thankyou po s mganatututunan namin.
against ako sa pmax computation, kung different Ampere ang panel oks lang yun as long as parallel at yung lowest volts ng panel ay pasok sa charging requirements ng battery. e.g lowest voltage ng panel is 18v pero 12v lang naman ang battery, papatong parin yan unless 24v na ang battery na gagamitin. sa series connection hindi talaga recommended pag different Ampere since dun sa mababang Ampere na panel mag kaka bottleneck dahil hindi dadaloy ang mataas na Ampere sa lowest Amp na panel, solution iparallel ang dalawa or tatlong lowest Ampere na panel para mag match sa biggest panel na nais i parallel. make sure na in good running condition ang panel kung mag parallel, pag hindi cgurado pwede gumamit ng high Ampere diode sa positive or negative side ng each panel para forward lang ang direction ng supply at hindi babalik ang supply sa may issue na panel. expect a 0.5Voltage drop pag may diode but you are safe to go mag parallel kahit iba ibang specs wag lang mas mababa sa charging requirements ng battery.
ben tulfo kaanoano si sir legaspi just kidding always watching sir...
😊👍
Gud am,magttnong po kung myron kyong mai-recommend n complete guidebook abt solar power system installation from designing (computation or formulas) & up to the completion of installation).Tnx.
Paumanhin, wala po. Etong channel ko ay kompleto sa mga tutorials about pv system.
Sir JF, additional po ito sa kaalamam ko, salamat
Wala pong anuman 😊👍
Sir gud day, pra walang agam agam ang gawin n lang ay puruparehas lahat ang specs, lalot diyers ka lang . Di ba poh . Inuulit ko mga video mo at natuto nman ako slamat god bles...👍
Mabuti naman at may natutunan ka 😊👍
ung sa akin po sir ay 25w at 10w naka parallel sya..
imp 0.56 at imp 1.39 Vmp 18v
1.95x18=35.1watts
Tanong ko po sir JF kung tama ako. Mayroon akong pv 2x 100w Vmp 17.6 at imp 5.71na naka parralel connection at sineries ko sa isang 200w na may Vmp 19.69 at imp 10.21. Ang reading sa scc elejoy 600w. PV volt:48V at CHG current is 16a. Kapag imultiply ay maging 768 out of 400w.
Good Am Sir JF, inquiry about latest Trina solar panel same wattage but different specs.
New Model
Trina Solar
VMP-33.3v
IMP-15.03A
500w output
Old Model
Trina Solar Vertex
VMP-42.8v
IMP-11.69A
500w output
Solis 3.6kw inverter
Ang sabi kasi sa store sa angeles di daw pueding i mix sa old model kase mababa ang VOC tas tumaas ang ISC and IMP.
Puedi ba itong i connect and mix kasi i did the math pero pareho lang ang output nya kung dadagdag pa kami ng 2 solar panel, 1500w ang first 3 previous commection kung dagdag pa kami ng 2 na solar para 2500w output power sa inverter. Correct me if i made it wrong ang computation.
(3) vmp 33.3v = 166.5 voltage series
(2) vmp 42.8v = 83.6voltage series
11.69A X 195 V = 2,279.55 wattage output
Or puedi bang gawan nalang ng separate string papunta ng inverter sa PV 2 input? Magakakaroon ba ng problem regarding sa set up.
Ano po ba ang pueding gawin na solution or connection sa aming set up.salamat po in advance, please help and advise. God bless po!

Sir, wat if 3pcs 550w panel. Tas ang koneksyon po is nka series ung dalawa tas pinarallel po sa isa? Pwd rin po ba yan ung same lang po sir na hnd po magkakaiba ang watts po?
Sir JF is it posible po ba na if meron akong inverter na operating dc voltage 45-90v. is it posible po ba na gagana sya sa 50v voc series with 30 voc na panel? in short , magkaibang VOC ang each panel in series?
Sir, may 4 panels po ako na 200 watt each.. same specs lahat. Plan ko mag 2s2p connection pro 24v system po set up ko, pwede ba po ung 2s2p sa 24v system set up? Help namn po, baguhan lang po sir eh..
pagseries ang solar panel po Sir...dapat series din po ang battery po?, pagdalawa po ang battery at tatlo ang solar panel po...thanks...
Blessed day sur Jf,nkabili pi akknjg powmr na hybrid inverter 3.5kw 24v
Ang STARTING PV VOC VOLTS PI AY 150V ..MAY 4 NA 650W CANADIAN 45voc PANEL 2S2P CONNECTION. ENOUGH NA PI BA ITO TO RUN YONG INVERTER NA MAY STARTING BA 150V VOC?
Good day. Kung ang starting PV voltage ng inverter ay 150V, ang 2S ng inyong ay 90V lang. Hindi po sapat. Kailangan maabot ang 150V. 😊
Sir sabi ng iba okay lang daw mag oversize ng solar panel?
thanks Sir JF, saan po kaya pwedeng mag enroll for solar set up
Wala pong anuman. Marami naman pong nagko-conduct ng solar training na mga nagpo-post sa FB.
good morning sir JF pasensya na po sa abala, sa busy ninyong time, Sir clarification lang sa PV calculation, series parallel connection of 8 pcs na 400w with Voc 41.2 at Isc 12.28A at ang Inverter ay may max na Voc na 150v at Mppt SCC na max 80A, kung ang connection ng 2 series at 2 parallel 123.6v at Isc naman ay 24.56A sa anim na PV paano ung natirang dalawa na 800w, isasama ko rin ba siya sa naunang 2S/2P para maging 3S/3P, wala bang overload or exceeding sa Voc ng Inverter na 150v, salamat sa mga reply ninyo po at god bless.

sir JF magandang ARAW po, may mppt po ako 60a max nya is 1680w at 120voc sa 24v system, at may 4 solar panel ako 500w 42.8V(vmp) and 11.69(imp)
balak ko sana epag series kaso di pwd kasi limited lang kaya ni mppt ano po bang pwdng e.setup?, iyong pinagbilhan ko ng mppt nag suggest sakin 2s2p daw na connection, pwd po ba iyon ? kasi bka mag ka over sa Watts kasi mag kakaroon ng 85.6V(vmp) at 23.38(imp). ano po ba magandang safety suggestion nyo sir JF?
Dapat sundin kung ano ang nakasulat sa datasheet ng SCC. Eto ang tutorial kung paano mag match ng SCC at solar panels.
