Please does anyone have an idea how many solar panels a roof of 13m x 9.2m can take?

Hope the shape of the roof is plane, no too many corners/funny stuff? What solar panel wattage are you looking at, 255(~30pcs)-450w?

Note that the all whole dimension is not usable and your roof is not a perfect rectangle.

Need help on this pls.

Ordered an item via Ali express on march 14, 2021, order never arrived till the 90 days expired on June 14, 2021. Only to show order received. Other items I ordered on march 14 arrived in just a month time. I later ordered same item from another store and received it in less than a month.

I have manage to open a dispute on the said item. But is this how the automatically confirm order after 90 days even though I am yet to receive it?

Yes

The problem I have is, how did the police get to know about the killing and the hideout of the boy?
Bandit went to report him at the police station, or police got to know that they were short of two personal(bandits)? So many questions to ask about this ban..... Police force.

Arrest him for what exactly?

chris81964:
Someone told me that I can connect the PV inverter to the load side of the battery inverter. I will explore and do a new video when I do

Exactly!
You wouldn't be limited to the 5kw of your hybrid.

chris81964:
You are most welcome. Thank you for being the first to comment. Doing it from the gen port limits it to 5000 watts which is the capacity of the hybrid. Yesterday when it got cloudy and it rained the system paid for itself. I had two AC's running and I got to 97% fast and when the rains started I maintained that percentage. During the dry season, system the system will be overkill

Could it have been done differently to get above the 5kw of the hybrid? Since technical you have 10kva combined. The extra watts may be needed during the dry season.

Barezzi:
No shading issues...
The South array is elevated with support and less than 10 degrees, while the West array is flat on my steep roof-I'd say 15 to 20 degrees.

I strongly believe this matter is spiritual!

Lol, it must be highly spiritual then!

Let me try and explain small. Before you conclude this, did you observed this for a period of 1yr and the cumulative results showed this?

If you are observing it around this period, it very possible cos the sun is moving more to the north and sets almost in front of any west facing roof side. Secondly, ur inclination angle of around 20degree is very optimal for west-side roof, any time from 1pm till sunset. So, as long as the sun it out shinning, u will keep smiling to the "bank".

Barezzi:
I've noticed that my West facing 4800W pv array consistently outperforms the South facing 5200W PV array.

Are they the same panel brand?

gameboy55:
I ve not put that to test though, we uaually ve power supply from grid for a whole week untouched. But they do carry out maintanace which might last for 2 to 4days

DURING THOSE DAYS, I USE MY GEN FOR JUST 2HRS BTW 7PM TO 9PM TO CHARGE MY BATTRIES (reason for additional panels).



So far, I think my pwm CC is working fine for me becos I make use of 1 deep freezer and 1 refrigerator which is always ON from 10am to 3pm everyday. 1 55inch tv, home theater nd decoder which is usually ON nd 1 43inch tv nd decoder (only ON wen in bedroom), among other lesser loads.


My batteries has neva gone low with this setup.


MY REASON FOR ASKING OF ADDITIONAL PANELS IS TO ELIMINATE THE 2HRS GENERATOR USAGE WHEN THERE IS NO POWER FROM GRID.

I think you have a problem of storage not charging.

Or is it that the batteries never got charged before 7pm?
How is your usage like during those day?

stevebond007:
With some of the info I have been able to process, one can build a 5.0kva solar inverter system with #1,000,000

Kindly list the info u have processed, u may be wrong.

He who has ears let him hear. LG is no longer in existence. They have now been reborn as Hisense. Japka if you see any brand new LG product that's not old stock.
Thank me Later

This is new to me, though I ditched LG(Nigeria) a long time ago!!
Thanks for the info

SaintUlot:
Like how much will one spend to achieve this and will i save money ditching phcn and their estimated bill on the long run, taking into account that solar back up batteries don't last more than 5 years and the battery is the most expensive of the set up.

How much depends on the product you are willing to pay for.

with a 2.1kw pv(minimum, battery capacity will determine this too), 5kva inverter @48v, 45a mppt controller(battery dependent), batteries(LiFepo4 or lead-acid, depends on you, also backup time will determine batteries capacity) and other stuff. can you paint a picture of what you intended to run, I already know of pumping machine and electric iron?

SaintUlot:
Many people have confirmed that going solar is better than running generator, but nobody has confirmed that it is better than PHCN afterall. Lets assume you live in an area where PHCN supply light regularly, but estimated billing is suffocating you because they refuse to deploy prepaid meter and you wish to go solar 100%.

The challenges one will face is that using appliances like pumping machine and pressing iron will drain the solar system faster and to put up a set up that will accommodate those two appliances seamlessly will increase the solar setup budget sporadically.

Which part of Nigeria is this? less than 10% of our population will enjoy this.

you can run those appliances during the day and you won't kill yourself budget-wise(though u still have to spend too, nothing good comes cheap)

Dam5reey:
Issue is most want to buy cheap products and expect it to work like brand new, Even LG brand new I bought from LG had remote sensor issue after one month though LG repaired under warranty..

If you want to buy product and have 2 years warranty just go to Fouani store or similar, stop looking for cheap deals and say someone scammed you, even seller may not know.

It's 50/50, when you buy used especially from Alaba.. it's not something New.

point of correction, it is 20/80, from Alaba, it cant never be 50/50(this is too good)

Ceaser01:
2s 3p should do. I'm not sure the max VoC of 2 series 300 watts panel in series approach 80v. Although I may have to confirm from my setup.

He should not do 2s for a VOC of 75v for 300w panels, the ones I have seen cross the 40v/panel mark easily.

earthrealm:
Too bad this happened.
I wish i didnt hold my tongue...

First question i 2anted to ask when i saw justmenuels advert for the LG inverter ac was, is there no founai office near you?.
Why patronize other sellers when accredited Lg dealers dey every city..

My Lg Inverter ac i bought direct from founai Lg office developed issues after the first yr. Lg repaired it free of charge, replaced the compressor, and i didnt pay a dime.
Dont see justmenuel or most sellers on this forum having that type of waranty/after sales service.

Their first strategy is to try and blame you for the malfunction and later graduate to pleading, if they are boxed in a corner

Wao, sorry for the experience, it's a very sad one. I was looking for a tv to buy about the time u did. I had bought LG tvs some years back, 2012-2015. All new from LG main sellers, in akure, Ibadan and Ogbomosho. Mine, 125k, my brother, 90k, my in law 85k and my flat mate, 100k. Reason I went all out for Lg was, I had one from UK, up till this moment, no stab or surge protector or anything. The tv is connected to mains 24/7 it goes off whenever there is power outages. Still working fine. So, back to the Lgs I bought, none survived the surge, or any irregular voltage, mind you, all was connected to stabs! Except the one from UK. Since then I vowed never to near anything labelled LG. Except the ones from UK or Europe. So I went in search of used Tv, my first stop was here, naira land, and I got to those threads, including the one u talked about. All they were posting and specs are not just adding up, including the pictures(mind you, women can't collect money from me, but electronics will), so before I pay, I do my research. That's was when I discovered that this guys in Alaba do couple this stuff together, though I do repair tv in Alaba way back, I know my people very well there. After none could convince me, I just locked up I went for Sony that nearly cost an eye

ranktzy:
Hello to you sir, I see you've used Trojan flooded cell batteries & managed them well. I have an uncle who uses 4 12v 200Ah Trojan batteries, he recently complained the inverter goes off when the sun sets for the day, so I went to his house and found out the batteries where no longer storing charge cause the moment it's loaded, the voltage drops instantly. I checked the config of the inverter, it was set on flooded, but it has no equalization feature. Do you think the batteries can be salvaged if subject to equalization, & what external device can I use to accomplish this. Thank you!

Change those batteries, don't waste your time, effort, money and peace of mind.

mahkanjuh:
please, house, does anyone know anything about this solar panel product? picture attached
please, is it going to be a good buy?

Google the name and find out yourself, you learn better that way.

Note: that picture is not very clear, I know the panel is a brand and has a footprint here in Alaba.

olopan:
The last time we tried partnership with Yingli, the but charge didn't take us serious .... So we took our business to Flames as a budgetary panel but these days ....

The name plates stats we observed are between 2.93 to 3.1 of name plate and it's quite not that fantastic to me.

In our recent install the Canadian PERC cells beat flames Half-cut cells which were suppose to be more efficient over conventional PERC cells...

After like 4years of use, check flame production. You will be deadly shocked!

Flames is a none existence brand(i want to believe it is/was a label in naija)

It is so sad that we have been played into the hands of these clueless ones. This is the case of the land of those that can see being led by the blind!
Keke NAPEP being used as a monitoring vehicle according to them, "for urban planning and development", in 2021 where Geoinformatics is deployed as a tool for sustainable development.
I blame the youths that have refused to also check up on what is happening in other climes via YouTube and Google.
Our youths that are so obsessed about WizKid vs Davido vs Burma boy, Arsenal vs Man U vs Chelsea...... supremacy, which is not a major problem. But referring to this cluelessness as a welcome development is simply obnoxious!

God bless u!!

Saipro:
Those who "claim not to be pros but we know them" might hate me for saying this (as it's something anyone who's done reasonable research should know, long-time installers know and copycats might know with this post) but ... you should by now have realised Canadian Solar modules aren't made in Canada.

Born and bred in China, the main brain behind it, Chinese

wilmaria14:
dis is 350w half cut will send d picture of my won 350w and u see sir

Ok, noted. I will visit your place one of these days.

This should sort things out a bit.

Boys!!!

Your mama don't know your pin, your brothers don't, your sisters, hmmm, no!

Na f..k mate, sorry, girlfriend, knows everything. Guy live with that, and move on!
Hope you have learned something?

abbeymighty:
Please is 250 watts * 6 Canadian solar panel OK for 48 v hybrid inverter set up? Please urgent response. Thanks in advance

Try and add two more, making it 8 in total, at the minimum.

abbeymighty:
Hello house, please what is the difference between electrolyte and distilled water?
Urgent reply please

Calm down!!

(a)Electrolyte na acid(H2SO4, chemistry stuff)

(b)Distilled water, de-ionized, na 'water'

Note, (a) can deform you if not handled with care. In fact, for u asking, I take God beg u, don't go near it.

olopan:
The effect can't really be noticed instantly sometimes

Except one goes head on to compare both in the same location and area just like victron did in Romania

From my personal experience I have discovered tier 1 trump over tier 2 in

1. Daily harvest and yearly harvest. Even if they are both the same capacity

2. They hit peak production for several times of a daily power production ..

3. Many tier 1, I observe works 58-73% efficiency of their power when at maximum and more predominant around 60-63% ... Could be more but maybe not observed while tier 2 works between 45-65% maximum that I have observed but mostly 50-55% is predominately constant

I strongly believe that there are tier 1 and tier 4 solar panels in Nigeria, no in-between. You have mentioned some tier 1s. If there is any tier 2 or 3, I will like to know such panels.

cluewebhost:
I've been going through this thread and I'm confused.

What sort of setup would I need (solar) to power this AC?

I only need it on for 6 hours when I'm asleep

It shows 940W and 4A.

The rest of my load is negligible I use 2 - 2.5Kwh a day for 12 Hours of grid power - Refrigerator, Computers etc.


How many panels would be sufficient?
How many batteries + capacity?
I assume a Hybrid inverter would work but would 3Kw be okay?

Is there anything else I should know?

If I get you correctly, this are day time loads, ie during the day, right?

cluewebhost:
I was ready before I asked.

Ok, beautiful!

Yes,
Those rest loads are not negligible.

To power that 900+ watt on batteries for 6hr "off grid"....
Firstly, can you keep around 3million naira somewhere for this project? Before we start to analyse.

Sorry if this is too direct.

JustCryptos:
Ps. This will be a long read. Biko helpe.

Good morning to all the gurus in the house. Please I have some questions and need some help. I'd really appreciate some answers. My case is peculiar

I am still in the process of building my house, with plans of moving in in the next 4 months. We are almost at the electrical wiring phase.

Here's the major constraint regarding the site.
1. NEPA light is yet to get there. There is power supply on other streets but not on mine yet.

2. The location is still largely inhabited. There are only 5 families on the street with a lot of bush around.

That being said, I'd be relying fully on solar and gen to power my appliances.
There has also been no recent incident of crime, but security is my priority.

Here's what I have in mind that needs some vetting.

1. During the piping, I asked the electrician to split the load. I purchased two DBs and requested that all lighting (internal and external) be sent to one box, while the second is left to carry other loads.

My reason for this is because, I don't want my lights (especially external) to go off at night even if the house is not powered. Overall, I estimate that lighting may consume 150 watts and run for about 11 hours.

Is this a good setup to adopt?

To this effect, I already purchase 6 used 200 watts panels from Oga valto. I already have a 1kva mercury inverter setup. However, I'll be disposing my current batteries for 2 200ah batteries to support my lighting needs.

What else do I need to add to this setup to make it functional?

For the internal load, priority is one freezers (make my madam no kill me). Other things like TVs and fans come in once in a while.

I am estimating about 700 watts for the entire freezing load, expected to run for 8 hours daily. Once in a while a 1000 watts iron may come up or a 1hp pumping machine.

Other loads such as TVs and fans come up to about 300 watts and should run for about 5 hours daily.

Can someone please help with a breakdown of what I need to achieve this? Let me start saving. I am not also looking to get everything done at once. I can upgrade in the future.

Can you go 48v, and how dip do u want to go pocket wise?

Iron, water pumps, the freezer can be powered during the day.
