lolz , na for panel e worst oo.

What brand of tier 1 panels do u recommend and do u ve any reputable seller here or offline? I de fear solar resellers.. na so i see one electrical shop de gum stickers 4 circuit breakers 4 alaba

FabulousAutos:
Good morning house.

Pls can someone help me review this bill.



My plan is to buy two more batteries and more panels before end of the year. Also, what product will you recommend since the technician chose not to be specific?

This quotation get issues but wat do i know. Let me wait 4 d elders

hello house.. Few articles i have come across suggests that solar panels should face south for optimal energy production. I decided to check on my panel direction using a digital compass on my phone this is what i get.. Does it mean my panels are facing the north? I have been getting poor outputs from a 1.2kw setup.. Althought i was not the one who mounted it.

Today i went to aanother location where the roof position was pointing in a south east direction with panels on it.. i also want to know if this is a good direction also..

I will appreciate all comments from everyone... thanks

Btw jinko and Canadian panels which is better.. Apart from gennex, any reliable seller for original canadian panels

Hello good people,

I installed six pieces of 350 watts Felicity solar panel mono (3 each in series and paralleled). That is totaling 2,100 watts. I’m using 3.5Kva/24v Felicity Hybrid inverter IVPM 3524 with 80amp inbuilt MPPT charge controller.

The system is only able to generate 1,200watts maximum on very bright sunny days, even with depleted batteries and load. So I’m wondering if other users have similar experience.

This means I’m loosing 900 watts of my total installed capacity.

Is this normal? Please what are your experiences?

Did you check each panel individually befor mounting? What about the direction of your panels? Any shading? Can we see pics of your installation.

Around Q4 last year. I upgraded my solar panels from 9x 335 Yingli panels to 9x 600w Canadian Hiku7 solar panels. Bought panel from techland.

Here is a short performance review.

Installation. The panels are roof mounted with a 21 degree tilt. They face South East at 123 degree Azimuth.

The panels are paired with a 100A / 150v Victron smart solar charge controller. Total capacity is 5.4kw.
9 panels are connected in a 3SP3 arrangements. There is a 10mm2 shielded and UL listed cable between PV and charge controller. Cable length is about 10 meters.

Overall the system performance has been really good. I get an average of 4.5kw output which represents over 80% of panel PMAX.

One thing the panel is really good at is how it handles heat. It has a heat co efficiency of 0.34% and this shows in the performance. Yesterday ambient temperature (as pulled from my personal weather station) was as high as 43C, yet the panel was able to produce (consistently) north of 4400w.

During cloud edge events the panel has produced close to 110% of output which is 5.8kw of 5.4kw PMAX.

I attached 2 centrifugal fans to the Victron solar charge controller to help handle heat since I am using the controller close to it's limits.

Very impressive.. so does it mean the canadian panel has more performance over d yingi?. How much did i get the canadian panels sir ?

First check if your hard drive connection is intact

Did u or ur engineer downgrade your operating system say windows 10 to windows 7? if yes u have disabled UEFI BOOTING options to legacy to support older windows operating system.

You made mention of no backup (battery). Most laptops now dont come with a cmos battery.. settings stored on bios are being backed up by the laptop battery. so if the battery is dead, there is no way the bios setting can be saved hence it results to going back to factory settings which is UEFI booting and ur pc is set to legacy boot..

my take here is this replace laptop battery and go into bios setting and allow legacy boot options.

Please, be very careful with this installation. One mistake and the fan won't work.

I got 2 units from a seller on Konga via offline sales. My installer made a silly mistake and the first one didn't work. We had to watch a video from YouTube (link below) together and we corrected the mistake in the second fan.

I had to reach out to the seller who then directed me to the distributor at alaba international who finally directed me to their service centre also.there in Alaba and it was repaired. It was not a palatable experience. I spent the whole day on that move.

pls where is the service center in alaba? i would really appreciate if i can have d address

sometimes i wander wat some piple tink. wen did Tinubu turn lagos IGR to 5 billion? Lagos enjoyed so much benefits as the nations capital for almost 70 yrs or more than. Several piple conspired to starve other regions of thier economic uplifment. Take away sea ports from lagos and see the empty skulls. The ibos you piple hate so much runs the affairs of Lagos business wise. How many yoruba de do business? From importation to exportation and logistics. Some of you just stay behind your keyboards to type rubbish here..

Tinubu has nothing to offer anymore..

hello everyone where can i get original canadian solar panels.... is there a sole distributor here in Nigeria? not alaba sticker panels ooo.....

Hi everyone, i seek solutions from knowledgeable people here for genuine companies that do forward items bought on US sites to Nigeria. with moderate shipping rates. Most of the ones i have tried are a complete rip off thus making the things i bought online look more expensive due to their greedy rates... some
All ideas are welcomed.... Thank you

If Tinubu can gather this crowd in Delta that's expected to be won by PDP then I see Tinubu winning the next year election by landslide margin


Underestimate Jagaban at your own peril.

The day Jagaban won APC primary was the day he became Nigeria president

gada dust abi fire.... do u know how many luxurious bus came from lagos state just to grace the occasion... they rented crowd from lagos and brought them to delta state...

Na we be deltans Na we de stay wafi... if u de doubt me i go tell u where dem lodge dem...

Good day house, want to get Lithium battery build from Valto. I need vouches for him and his products.

bros u nor get problem... just do as he says and be transparent....valto save me from high bp.. i am enjoying my lithium setup

hI everyone,

my cousin has been suffering serious ulcer ailments for sometime now.. infact we are tired of buying drugs as they only supress it for while.

Is there a permanent herbal solution to this.....

mctfopt:
Use DHL or FedEx. Kinda expensive. I've received goods sent via DHL in 4 days.

are there no frieght agents that deliver to lagos... dhl n fedex nor be where person de look up 2

hello everyone i am new here...i want to purchase something from aliexpress but i dont think i have the patience to wait for the next three weeks or so.. is there a way out... say i receive my guds in with a week?

Jefferyzz:
Check individual volt n amps of ur panels with clamp meter. I wanted to buy some used panels of 250w from alaba. I noticed the panel was showing 38v thereabout just for me to test amps n see 0.33a. n it was around 10:30 in d morning.

i only checked one panel with a pv meter. it was showing 22v and 4.99a (btw 1.30-2.30) translating to the 110w shown on the pv. i didn't check on the rest because they were same specs

zeestone99:

Are you saying the panels are substandard?

gadgetplanetng:
South usually gets better results here. Can you move them when the sun is up and measure?

that roof top get as e be oooo...

gadgetplanetng:
What direction are the panels facing?

from the compass on my phone that should be east..

fellow nairalanders pls come to my aid. i contacted a friend to purchase some pv modules.. Initial calculation was to get 300w*4 panels to charge a 4.8kwh lifepo4 battery.. Even the battery sef get e own story.. I am using an epever 30a 100v mppt controller

At first i didnt pay attention to what the panel was generating . But i later began to find out that the whole thing was not performing.. Pv modules are africell 300w.. According to my the installer whom i purchased the pvs from the connection was done in parallels. i was getting 29v 10-12a (pv input) during peak hours... This to me was unacceptable... even if there was a longer cable run because i leave down stairs (a storey building). When issues arose as to leakages on the roof i was determined to use the opportunity to check the panels . I borrowed a pv meter and the testing was done off peak hours on just one panel.. voltage and current were about 22v and 4.99a. which translated to 110w.

Now i changed the connection to 2series parallel 2 series.. My readings were sometimes 45/47v 5/6a, 50v/3a during peak period (pv input)...

I am beginning to think i was sold panels with stickers of questionable datasheet.. On a second thought if the panels were living up to expectations, the current in parralel was very close to my pv input current and the installer carried out the connection in parallel to the detriment of my controller.... E come be like say my journey into the solar industry na wrong entry

Has anyone used africells solar modules here. if yes are they reliable?

Oshomo12:
Seriously, who sold you this line? To connect solar panels properly, use the MC4 connectors abeg!

shuuu... it is well with me oooo.. maybe na substandard panel naim cos an

ceaser:
Maybe I should ask you this: Were the MC4 connectors of your panels left intact by the installer or they were cut off? This is important especially as you said it is a new installation that has worked for only three days.

In instances as where the MC4s are removed, the twisted panel wires often form an arc at the junction of the panel wires and the wire running the rest of the way to the CC. With the arc formed at the junction, a voltmeter may even show normal panel output voltage when measured at the point of entry to the CC. However the current required from the panels will be low or non-existent as shown by the CC.

does it mean removing mc4 connectors harms the current the pv is generating? please i need more clarification on this.. sometimes this mc4 connectors do not make good contacts

Let's hope some day soon, regulations can be put in place to separate the bad onions and Nigerians can get the best for their monies.

Just like someone said they always get majority of the jobs

olopan:
That thing can pain, especially when clients start saying i have a quote of lower price.

These days with the economy not looking so bright, computing quotations & juxtaposing with price is a big task

We have spoilt so many things in this country because of cheap labour.

we all have to admit it. solar is expensive.nor be all this corners wen we de cut

HeadofNairaland:
E go work bro.
But view urs as 200w, most pv na just pasted stickers.

so i nor go fit see panel wen dem rate @300w still output at least 220w. somebody de say make i buy Canadian solaror victron solar panel.

i just need rest of mind. Person go calculate add losses still add jara for the losses . panel go com de Bleep up

HeadofNairaland:
Test these panels on the ground. Adjust accordingly with a wedge or call som1 to assist u in adjusting to different angles. The result will be different.

Mine is on the ground resting on a 6 inch type building brick. One pv rated 190w used producing 130w. The highest amp I v seen was 10.9A. Cc Powmr. But usually 8a or 9a.

Probably my pv was just a "luck". Bc me sef no understand.

I dey find panels to buy oo even if na cracked.

if ur pv rated @ 190w de produce 130w .. its fair to me.. not my own rate 300w de produce 110... like u said na to bring am come down... but my guy u know how all this 300w panel de heavy to carry....
