Oga buy your 590w and use.

In my shop set up, I have two 550w, two 585w and two 590w (all Monofacial) connected in series and I don't have any issues at all.

Recently I wanted to add two more panels, I searched for 590w fouani no get, na so I buy 615w join am.

This is how it works.
In series, the same current pass through but different voltages. The smaller panels will limit the current of the flowing through the panels.

At the same current, the 590w panel will generate more watts than the 535w because it has higher voltage.


Though there will be a reduction in efficiency of the higher panels which I am OK with.

Valentinooo:
Mostly 2.8kw. Maximum I have seen is 3.1kw

According to you, you have

2pcs of 550w = 1,100w,
2pcs of 585w = 1,170w
2pcs of 590w = 1,180w
2pcs of 615w = 1,230w

Total Power expected = Approximately 4,680w
Actual Power harvested = Approximately 2,800w

bassdow:
of course it works BUT He / She should have certain things in mind. Also the gap between 535w and the almost 600w solar panels is wide BUT that doesn't mean it wouldn't work BUT still better He / She waits a little more. That it works, doesn't mean it's working as expected or should be done in the first place.

When you hear of Solar related fires, something like this is part of it. Of course some have done it for ages and had no issue BUT it's worth having in mind. Hence why atimes e better make those wey dey the field decide if it's worth it.

Back in the days, we could get away doing certain things BUT nowAdays that a lot of you prefer running high voltage setUps, coupled with lots of low quality MCBs, MC4 connector, cables, etc; One needs be extra careful

hoover420:
Okay thanks, that panel has been out of stock for over 3 months now. And I can’t find that particular 535 watt anywhere

look to see if you could get 500w or 550w. The one you mentioned is approximately 600w which is far from your 535w. Also, what's your installer (abi make I call am Professional) saying ?

twinskenny:
Boss choose whatever you believe.. I don't even know you to begin with! I believe you won't be offering an installer such a ridiculous price..

seems you don't get me BUT no issue

Paschal007:
I have similar challenge. I have 4 575w and I need 2 more. I have been waiting for them to have at least 585w. But 590w is not too bad. I have contemplated putting them on a separate charge controller but that's just expensive. I'll have to order it tomorrow.

Mixing solar panels of different specs introduces issues sometimes subtle, and sometimes not.

Shey make I talk say I talk am before about all these iregular capacities wey una dey buy then. Now people wey sell am no come get am again

Once again, I love ma way: my regular specs are 300w, 350w, 400w, and 450w . Worst case, I go 500w but when some of us talk, e be like say we no get sense

toyeoye:
For eligible solar users (with larger systems... 50kWp–1.5MWp), excess power no longer has to go to waste or sit unused. It can now be exported to the grid in exchange for credits, improving the economics of investing in larger solar installations.

Generate your own power, use what you need, sell excess back to your DisCo, Earn credits and reduce your electricity costs further

Hopefully, they're aware not all inverters supports such.

meanWhile, rather than do this, why not I sell low key to ma neigbours

twinskenny:
10kva deye inverter

30kwh lithium battery

16 no of 620w jinko

Location Osogbo

Installations fee 60k

Some client though... I can't even reply to this... I know some installer will sure take up the job

This one sha funny. Funny enough, have spoken to a few nairalanders who thought Giving out information for free ALSO meant I would be willing to do the actual work almost for FREE.
But it's rude not responding. That's if the above is TRUE to begin with.


...and I know You refering to mua

Ezimuoh:
You were the one that wanted to imply the type of battery used, when you said you wondered what kind of battery people use that go bad in 2 years

and when I wondered, I meant in terms of Quality; not battery chemistry

No worry; we would go with Sachet Water

hoover420:
Wow I just checked the Fouani website but they don’t have the 535 watt bifacial panel I wanted to order. Can I order the 590 watt bifacial panel they have, to compliment the single 535 watt panel I already installed? I’m confused, I don’t want to order for it then installer will say it cannot work with each other

you could but kindly understand the pros and cons of doing so. Would suggest you wait as the gap sef is much.

HustlingHustler:
Update!!!
I called the engineer to help me diagnose the problem with the inverter system. He detected that the battery terminal going from battery to the inverter was burnt and partly broken. Reason for the tripping off when using heavy appliances. He changed the wire and everything is working fine now.
Thanks to everybody who offered advice on how to go about the problem.
I appreciate each suggestion.

...and there were people who would have hoped the issue is battery related since you using leadAcid battery

twinskenny:
i dont know what you are implying but i don move.. it is easier for you to type all these guess you are not a regular site person. but try not to encourage what you suppose to discouraged.. there is a reason why we have DC and AC cable.

dont cut corners!

so You got evidence I cut corners just because I suggested means for those on tight budget to cut costs eh Oga Professional ?

twinskenny:
setup 8 batteries years ago for a client.. he used to run 2 no of 1hp ac on the system. tubular batteries was luminious inverlast.. such a good battery then before they flooded the market with fake ones

I'm quite glad you at least acknowledged that leadAcid batteries are capable so long they're quality ones and properly sized.

Now this is what I've always said annd implied whenever I speak about leadAcid batteries. Yes Lithium is better BUT if you can't afford the quality ones or don't have a reliable vendor, kukuma go for leadAcid batteries and while at it, ensure they're the quality ones else it's a waste of resources.

And actually, getting quality lead Acid batteries is much more easier than Lithium based batteries.

Someone just upgraded 8pcs of Tubular batteries of almost 8 years and He runs 2 standing ACs and 1 split unit AC among other loads.

Now We've moved him to Lithium because Oga wants to add 2 more ACs. Person wey him balcony sef dey cool. All doors have foam underneat to trap the cool air.

Now the lithium batteries occupies less space than lead Acid battery YET that doesn't mean the leadAcid batterie didn't dutifully serve their purpose.

So you see why I refuse to keep mute when people try to completely pait leadAcid batteries black.

As for the NEPA Aluminium wire; I use it personally and have deployed it for few clients on tight budget and guess what,, a lot of times, you could barely tell the difference. Of course my expertise on it didn't happen overNight as starting with mine, had to almost once in a year go adjust the connection then with time, realized how to connect them properly and it's been over 6 years I last touched it.

Aluminium cables ca always replace Copper. You just need it much thicker to achieve same or similar results and most times, depending on capacity of setUp, those ones sold down the street for less than 20,000 naira is what you need if you can't afford spending much especially if distance is long.

e get reason NEPA dey use am despite having all the funds. So me wey no too guide go come dey burn the small funds wey I get just to do what exactly when there's a simialr alternative.

Funny enough, nowAdays most people are doing high voltage setUps, Aluminium would give you as close a result that you get from Copper.

I'm not one to easily go south just because everyOne is doing so. Most time, I decide and know why I'm doing that which I do.

And personally, I don't see mySelf using Lithium batteries anytime soon despite knowing they're more superior and know where to get quality ones BUT that's me personally. For clients, I give them options, inform them on the differences and what to expecta nd most times, we end up deploying Lithium for them.

And Yea, Everything about Copper remains good except it's PRICE.

So no worry; I know what I'm doing

Bryanluke:
which one is original not cheap. They are all original but they only change stickers on the panel to another wattage. Your location in lagos

Hopefully you're just an end User

Dabss:
you didn't see the part where he said he was using it with AC? When I saw that part I just smiled and moved on. 😂

Did you also see this response https://www.nairaland.com/390522/solar-energy-complement-fta/2378#139612071 by @twinskenny in response to my comment ?

AyarmBoye:
sharp… the best investment is that your lifepo4 u just bought…you will enjoy it….. I use a transformer based inverter with my lithium battery (solar for charging with Mppt cc) I want to upgrade to hybrid transformerless but my problem is lightning,,I have much here during raining season and I Dey fear for the inverter..my current inverter is rugged and I haven’t even had issues since I got it even with all the lightning thunder I no Dey put am off..


I just one relate the later innovation but I Dey fear…I heard hybrid is more efficient in term of power consumption

Hope say You no dey Ogun state (Especially our side for Ota), rainy season comes with angry wind + random thunder / lightenings.

For our side in Lagos, and even most places in Lagos, rain dey fall gently with no trouble.

unFortunately, me dey use transformer based inverter for the 48v system so can't tell BUT I know 2 people using Solar pumping machine that theirs got so bad they had to buy another pumping machine. One of them even had to downgrade to our level.

Thing is, other than extra efficiency, transformer based inverters remains king. If possible, get 2 inverters: the transformer based Rugeddy baba for day time use. This could even be much bigger. Then a smaller or same capacity but transformerLess inverter to be used mostly from Evenings since their idle battery draw is often much low.

Also that way, you have extra inverter acting as backUp should one go bad which you could rely on till the bad one gets fixed / replaced.

But then again, with proper earthing, probably also thunder arrestor, good breakers and the likes + Prayers, you could face no issue BUT me no get that kind FAITH

Also, One must not leave inverter ON overNight unnecessarily especially if you got transformer based inverter from 5kva, or 10kva and above.

AyarmBoye:
bro even a taico 1.28kwh battery is better than 90% of lead acid batteries being sold at alaba

See eh, issue is most are used to FAKE leadAcid batteries. Back in the days when I got into Solar newly, My batteries no dey last beyond 8-months TILL I stopped buying the likes of Neptune and the rest. Quality leadAcid batteries dey wether wet or dry cell. Issue be say most of us go run from expensive ones, buy cheap Ones, then later come complain.

Once again, not saying Lithium chemistry ain't superior to leadAcid batteries BUT a low quality lithium based battery can rarely surpass a quality leadAcid battery.

For market, we dey call those fake batteries "Alaba Battery"

mctfopt:
People do it

You need to see what people subject their system to out in the wild.

I've seen things.

Surprisingly, some works, but sadly not for long.

Wait Ooo, so before Lithium battery, no One was using AirConditioner abi shey na me no understand una ni ?

Bryanluke:
Do we still have any honest and trustworthy solar panel seller in Alaba or Oshodi here... who will give any wattage panel and it'll be the exact wattage.

Some sellers are not trust worthy at all

There are Sir BUT at the moment, Quality solar panels (USEd or NEW) are somewhat scarce.

twinskenny:
you see the reason why people house get burnt.. here is an example.. i have seen things. some even using 3core ac wire to run dc cable

That's funny my dear. Houses wouldn't get burnt if things are properly done. Check well, Majority (if not all) of such houses you refered to all used Copper cable.

Make una dey try reason say no be only Naive + inExperienced people dey this thread na.

Anyway Sha, Hopefully you not refering to the Aluminium Cable OP refered to. And as for 3-core AC wire, or even 2-core or single core, such person ought be arrested. That's if truely na TRUE.

AyarmBoye:
chief even those used batteries sef nah luck…not many of us can identify good used batteries.A friend used a voltmeter to read one battery showing 13.8v ,.he bought it thinking it’s good and clean..only for the battery to drop to 11.6v under load…Bad battery !

your friend funny . unfortunately, checking for voltage ain't how to check battery health.

HustlingHustler:
Hi Engineers!
My 5Kva Felicity Solar inverter now goes off immediately Nepa takes light. It can't power most of my home appliances anymore without it tripping off.
It has been powering every items in my house since I bought it 2 years ago but now, anytime I put on AC, Fridge or TV, it goes off. Bulbs and Fans are still working fine.
Also, I noticed that the inverter has stopped making the humming sound or noise when charging with Nepa light. It is always quiet now when charging.
Please, I would love to know if the inverter or battery is what is faulty.
Attached is the picture of the inverter setup
Thanks

it's safe to wanna assume the battery is gone BUT would suggest getting an experienced person to examine your setUp. A properly cared for battery of good / average quality shouldn't packUp within 2 years

he should dig a soil pound and not caging those innocent fish inside one bucket.

Sheybi na if He owns a land that would permit such

Onkoolos:
Good morning guys, I have 545k that I saved in a bank giving me return of 7k per month, 2 months ago i saw a land available at place in ogun state after mowe ofada area. I want to ask should I withdraw the money to buy the land or keep enjoying the 7k..

Investment wise what is the best decison to take here

Pls banter and roasting is welcome. Because I’m here to learn. I know I’m not too smart.

Pix Google Image

which bank is that, what kind of account please ?

Also hope you know OmoOnile wahala in places like Ogun state means you need be prepared beyond just paying for the land.

Reloadedisraelp:
Animal are suppose to move freely.. . This one looks like caging

Another is, if you got your own land, get aboki dem to dig like 6ft deep and whatever width (though at least 6ft long and 5ft wide), use tapoline or cement to make it water prrof and do your thing there

You could plant Azolla and the likes around to help further cut down cost of feeds and probably even construct small poultry overHead using low cost materials in a DIY way

Also at this kinda small scale, na you dey feed those selling Fish feed and other things as you actually s pending more except you're able to improvise means to keep cost very very low

Same with those keeping poultry of less than 100 birds. To me, except the chicken dem dey chop around the bust / compound, buying feed as main means of feeding them is waste of money. Kukuma take that money go buy crates of egg.
