Watched the Auxano/BOI Video.
I must say l am thrilled that we have started from 'somewhere', guys lik that need all the encouragement they can get, to go "Automated".

Having said that, l must also point out that there is a difference between Assembling Solar Panels and Manufacturing Solar Panels.
What l see in that Video is a Company into "Assembling Solar Panels".
I did not see anywhere they Manufactured the Solar Cells, which is the backbone of a Solar Panel, they imported the Cells and then began to put them together.

But it is a good start, Rome was not built in a day.
With a good enabling environment, Govt can use its Diplomatic leverage to "buy Technology" from the Chinese/Russian/Asian Govts in a BOT arrangement, for our Entrepreneurs.

The Europeans and Americans wont sell such technology to us, they prefer we are always in a begging position, so they can continue to arm-twist us into submission. [/quote

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.

Thanks for the insight, the wire was cut off and joined den covered with aa tape, if it was the arc formed causing the low voltage what's the possible solution sir?

Good day,

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

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

Good day,
Does any of the supplier has this 350W panel in stock? How much is it, where is this available (Lagos preferred)

The same Company l mentioned above, (Gennex technologies, Lekki, Lagos), sold my Panels to me and they were ORIGINAL Canadian Solar, not the 'Put Sticker' types you get in that market over there.

Browse their website and see if you see what you like there. I saw a 375W Canadian Solar on their website,

@bolded is quite untrue.

The MC4s are designed to ensure perfect and fit contact with themselves. They are weatherproof and designed to last the lifetime of the panel. They are also rated to handle the current that flows from the panels. That is why arcing is quite uncommon at their points of contacts when used in installation, whereas the naked wires (after the MC4s are decapitated) will form arcs when huge current passes across the twist junction. This gradually weakens the joint and eventually the joint burns out, disrupting flow from the panels down to the CC, hence your voltmeter may give correct voltage reading at the termination on the CC, but no current will be detected by the CC. The naked wires too (even with black tape insulation used), are prone to oxidation as they get exposed to the elements.

So if the problem of arcing does not occur soon, oxidation will definitely come along later. The wire develops depositions, the strands become brittle and break off easily. You don't want to have this kind of problem if your panels are roof mounted where they are not within easy reach.

I guessed as much.

If your panels are roof mounted, sorry you will have to climb back on the roof. If it is a weak joint, twist the wires well. If it is an arc joint (with dark burnt junction and melted insulation), then you have to cut off the bad section and make another twist. After the correction, check back on the CC to see if its charging.

But I can assure you that the problem will likely repeat itself later on as it has to do with the junction not being optimal for the current coming from the panel.

So your best bet, which I implore you to do, is to purchase MC4s and rẹ-fit back to the panel wires.

buy original 360w real capacity mono solar panel from yingli office in ikeja or alaba. it is less than 75k. 280w is around 57k. their panels are real capacity.

HeadofNairaland:


182k will buy u:
Off grid inverter 34k via AliExpress
LifePO4 (12v 4psc, 37k x 4 = 148k )
PowMr cc = 47k from AE
Use d balance for Panels, charger,etc

It is just a 12v.

Probably ur tv will be 120w
Use 5w akt bulbs × 9 = 45w
Get rechargeable fans with 4 to 8 speeds version to allow for low to big watt. Max is 42w
Low setting will give u 15w give or take.

Remove d fridge for now and get ursef considerable amount of hours of energy.

Probably run only d mini fridge on a sunny day alone.

Run ur loads according to ur pocket as u don't need to break a bank to power ur appliances. Manage ur load like the way u manage ur salary b4 the next pay.

Dont compare ursef with some big boys in d house who will look at the above set up as nothing.

Bsideangel, I sell the Powmr CC for 55k and you can get it in less than 12hours if you stay in Lagos. I am helping you save the AE lead time, the uncertainty and, of course, the extra expense if you source dollars at black market rate.

You can thank me later...

Na wa o.

How do you even burn dry wood in an airtight container, hehn?! How will the fire burn? Even with fuel mixtures, oxygen is still needed for fire to burn.

See, I think you're trying to pass information across, but the way you are going about it is very nondescript. You don't even make effort to make detailed and convincing explanation and in easy to follow patterns. The way you jump from one discussion to another makes your depositions too abstract, uninteresting and non-catchy reads.

I don't mean to come across as confrontational o before you now reply me with diatribes, that will even be difficult for me to read smoothly sef.

The confusion is coming from the term "burn"..

Thanks for the reply. I did exactly like that but it didn't work.
I just took it for repair and realized most of the capacitor responsible for the charging were burnt. I didn't connect the stuff via stabilizer.
Na fixing level now though repairman say chance of it working well na 50/50.

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