Thanks Jesse, for the link. What I take from this is that: 1) If I use the 24v panels, under cloudy conditions, they can still produce some voltage which may be acceptable to the MPPT (which may need minimum voltage to operate). I should also be able to charge my 12v battery system, as the MPPT charge controller will take care of that. The only issue is that I am not able to use 12v equipment unless the equipment is directly connected to the battery. 2) Even though I use my panels in series and partial shading occurs on one panel, the cut off diodes will restrict this panel, while all other perform optimally. Is this correct?

yeah yeah, I get it. Now it would be great, as you have already done the research, propose the panels that do the best (that have the by-pass diodes) by manufacturer. Also you have mentioned about the small print, as you have already done the research, you should put up proposed good panels and we can buy using your vendor and you could benefit too. This is a Win Win for both of us, as you have already done the research. Only point out the products / Vendors that you know are significantly better and suggest those and earn from our qualifying purchases. I (I guess most of us watching this) would be interested in the Vendor / panels / efficiency / by-pass diodes to make the buying easier - or else put up a video about the buyers guide with the existing online vendors. IMHO that would be the greatest bang for buck.

Thank You for your video! It was very helpful! I'm just a bit confused about something concerning the hook up from my generator to solar panel. I've got a small size lot, so I want to use 'just one' 400 watt (4-in-1) solar panel. Also, they say I can charge my generator 'quicker' if I go parallel. But, don't you need more than one solar panel; to connect a generator to a solar panel in parallel? I'm trying to decide to whether to get just one 400 watt panel, or, two 160 watt panels, to get a few hundred watts back to the generator as quickly as possible. Also (if you'd be so kind)... EcoFlow says their Delta Solar Generator can charge up to 100% in about 1.6 hours via AC receptacle charging. BUT I've also read that one should "Not" charge a Lithium type battery up to it's full 100% And, should Not use or discharge down to less than 20%! Folks say Lithium type batts are "So Much Better" than a Deep Cell or AMG Types b/c you can only use like 50% of those other types of batteries! So Why go with lithium batts, if you can only use 60% of their capacity? And, what could be wrong with FULLY charging Lithium Batts to 100%? And why not discarge to just 20%? I'd really appreciate your input Jesse! And Thank You for your time!

@@SolarSolution Jesse, (unless I missed it) in the Udemy course, I think it'd be very helpful to have more details on sizing and configuring solar arrays (serial/parallel) vis a vis solar charge controller, inverter and battery capacities. This is what I'm dealing with now with my 7,400w solar array, two Midnite Solar Classic 150 solar chargers, 48V Magnum inverter/charger and 8S2P Rolls Surrette S6 L16-HC battery array.

Greetings Jesse. I’m in the process of building an array that will have 32 360 watt panels. I will parallel 2 strings of 8 into one string so each parallel string will feed one of 2 Growatt 5kw inverters. I’m wondering about a few things: 1. Should I put one or two grounding rods near the array, how big, as in rod diameter and length, and distance apart? 2. It makes sense to me to have the parallel connection at the array. That way, I only run wire from the panels to the solar disconnect switch which is mounted under the array, and not all the way to the Growatt inverters, some 35-40’ away. 3. What components would you suggest in my case? I don’t know what the schematic would look like, as in: panel wires into a fuse or breaker box then to solar disconnect switches, one per array, or if switches should come 1st, etc. any help would be much appreciated.

Great job!!! I' m from sri lanka. As a srilankan, Every day We face severe power cuts due to lack of sufficient fuel & water. We are currently experiencing continued power cuts during the day and night. This is becoming a part of normal life. Children are studying using kerosene oil lamps.

Can you make a video showing a few strings of panels where each string has two parallel series of panels. i.e. two series connected panels of three which are then wired in series together. Wouldn't this combat the voltage drop from low irradiance and the partial shading problem? With blocking diodes on the panels it would combat the shading problem even more. No need for microinverters.

Big thumbs up!! I'm also a Mechanical Engineer but in the Ammonia industry and have forgotten my solar energy theory. I want to oversize my solar panel by 35% to take advantage on cloudy days . But Is this safe when there is full sun ? My inverter does have a solar charge controller. I've been told the inverter will only absorb what it can. Please confirm?

excellent explanation, thank you. I wonder If I have 3 roofs all solar panels in series. What is more efficient. Invertor with 1 string for all panels (cca 23 panels and different directions) or Invertor with two strings and split roof for 13 panels main roof and 2nd string with 10 pannels) and all in serial with optimisers?

That said, tin copperplaterd wires all over, as less distrubitions as possible etc, but when i looked in on a battery isolator that was fitted when buing the boat it was a Victron Diod one, learnd they have a 0,7v drop of effeciancy from generator to batteries, a hell of alot.

U need 2 check with the manufacturer if the inverter can handle the 14x43v = 602v maximum of ur panels in series I would go with that... If the 500 is a hard Max, then u will have 2 do 2 strings in parallel... It also depends what country u r in & the min-max temperature range... (The colder it gets the higher the voltage will b) Ur other option is 2 use a different inverter... Series is better (if possible) as u will have less losses & generate more overall... Hope that helps.

Hello Mr Curry, thanks for you question. For personal advice you can contact me through the main website. All the best, Jesse www.solarsolution.co/contact

Hello please let me know what you suggest for the best setting for luminous solar battery 12200 I have 4 Battery 200 amp connected to inverter 48v Inverter app setting: Battery Parameters Setting: -Battery cut-off voltage: -Back to grid voltage: -Back to discharge voltage: -Charger source priority: SUB -Max. charging current: -Max. AC charging current: -Float charging voltage: -Bulk charging voltage(C.V. voltage): Regards

Wait in parallel panel connectin if one panel reduces the power due to shading. it will affect overall ouptut. parallel connection required the same voltage. If the one-panel output voltage drops and parallels to others. the overall output will depend on that lower voltage one. because all other current power generated will flow to the lower one instead of the solar controller. For that, if connected in parallel it should connect the blocking diode on each patch so that the current generated from all other full power panels would not flow the current to the lower voltage one. Do you agree?

Thanks for your feedback Sayi, would it be possible to re-phrase your question and make it more specific? Thanks, Jesse.

Hi can you please kindly help me on my solar panel I have Panasonic VBHN330SJ53 330W Solar Panel Module which I have connected 7 panels in series which is 7 x 330 watts = 2310 watts dc voltage approximate 483... And I have another string same solar 7 x 330 panels in series which 2310 watts Can I connected this 2 strings in parallel so the dc voltage approximate will be 483 and the total watts should be 4,620 will this system will work ? Please kindly help me on this thanks you Sam

Can bypass diodes be built into each and every cell, rather than each panel?

An excellent question Nic! That would indeed drastically increase the panel's ability to withstand partial shading, though this is rarely done. Based on your question, you might also be interested in the video I shared specifically on bypass diodes in PV modules: kzread.info/dash/bejne/aXeBx5Oogru2dqQ.html. Enjoy! All the best, Jesse.

Most modern solar panels with 60 cell 66 cell 72 cell or split cells (120) generally have 3 bypass diodes. Each diode covers a third of the panel. More diodes would obviously make the panel more expensive. Also diminishing returns with multiple diodes and of course, more points of possible failure.

If you connect solar panel in series does the wattage of the solar panel increase or decrease?

yes, the wattage will increase. in parallel the voltage will stay the same and amps will add up. in series connection, the voltage of the solar panels will add up and Amps will stay the same.

Please help! 4 separate inverters?? I have 48v 30,000w two phase inverter and two series 300ah battery banks. Need advise on configuration of the 24 individual single diode PANELS. Panels to be install in two layers. I.e. 14 on top of 10 lower pneumatic slide out panels. Each PANEL specifications as follows: 1. Panels wattage 180 2. Low temperature Arbitrary -10F 3. STC 25 4. VOC 43.2 5. IMP 5 A 6. Temperature Coefficient of Voc -.33 7. Temperature Coefficient VMAX -.44 8. WMPP STC: lrradiance 1000 W/m2, module temperature 25 °C, AM=1.5; Since the bottom 10 panels may not always be exposed, helpful to configure setup please.

I am thinking for best effeminacy (considering are each single diode panels and any shading maybe an issue) to connect them in four Separate solar Array strings as follows: TOP two Strings A) 2S4P (8)= 100v max/20A (max 35A) 45’ (15M)=10AWG B) 2S3P (6)= 100v/15A (max 26A) BOTTOM two Strings C)2S2P (4)= 100v/10A (max 17.4A) D) 2S3P (6)= 100v/15A (max 26A) CABLE SIZE All four 60A, Max Amps 105A

Sir i wana work with you

how do I know if bypass diodes are installed

Hello Michael, thank you for your question. There are several ways to approach this, two options would be to either check the datasheet, or open the junction box. Good luck! Jesse

Pretty much most, if not all modern popular panels will have 3 bypass diodes incorporated. As advised, check spec sheet to be certain.

We have 4 250 amp gel batteries connected parallel, we have 6 100 watt solar panels connected in series and a 60 amp MPPT controller but the batteries are only charging to 12.1 to 12.3 in full sun. What are we doing wrong, shouldn't we be having 13 or better?

Hi Scott, thanks for your question. I'm sorry to hear your batteries are not coming up in voltage. Great by the way that you got the gel type, if you picked the right brand you can get really good performance out of them. The voltage levels you mention are definitely worrisome, has this been going on for more than a few weeks? Is your voltage reading accurate? How old are the batteries? Are they 12/6V? Did you measure them individually yet? Have you checked your charge controller, and your panels? It is probably caused by a relative simple topic, but you would do well to figure it out as soon as possible in order to avoid [further] damage to your batteries.

@@SolarSolution Hi Jesse, I checked our system over the weekend and found out our 6 100 watt panels are producing 20 + volts, our 4 gel 250 amp batteries each have 12.4 volts. We installed our new renogy 60 amp rover and on sunday at 4:10 pm we had 60 amps from solar to controler, 0.7 amps, and 12.3 volts from batteries. When I checked it this morning it was 50.3 volts solar to controler , 0.1 amp, and 12.0 volts from battery. I dont know if my wiring is not sufficient enough for the batteries or that we are loosing to much power within the 100 feet ( using # 6 wire) from our solar panels to our controler I am just not sure.

Hi Scott, thanks for your message. Here are some thoughts in response to the information you provided: a. QUOTE When I checked it this morning it was 50.3 volts solar to controller , 0.1 amp UNQUOTE: You might get more insight in the operation of your system if you would work with the value of Watts [Watts = Volts x Amps]. In the situation you mentioned here, your PV system [of 600W] was producing [50.3*0.1=] 5 W. b. QUOTE We have 4 250 amp gel batteries connected parallel UNQUOTE: FYI, I would avoid at all times to wire more than 3 conventional lead batteries in parallel, since this enhances battery bank instability over time. c. QUOTE I dont know if my wiring is not sufficient enough for the batteries or that we are loosing to much power within the 100 feet ( using # 6 wire) from our solar panels to our controler I am just not sure. UNQUOTE: You may verify whether your voltage drop remains below 2-5% with online calculators, there are plenty available. d. QUOTE We installed our new renogy 60 amp rover and on sunday at 4:10 pm we had 60 amps from solar to controler, 0.7 amps, and 12.3 volts from batteries UNQUOTE: Following the same approach as mentioned under point (a) above, your figures indicate that you were charging your battery bank with [0.7*12.3=] 8.6 W. Not a great yield from a 600 W solar array :(. e. QUOTE Hi Jesse, I checked our system over the weekend and found out our 6 100 watt panels are producing 20 + volts UNQUOTE: It is not clear to me where this value comes from, did you measure the open circuit voltage [Voc] from the panel? If so, this value however useful, does not give complete insight in the functioning of the panel. I hope this helps Scott, good luck! Jesse
