Oh dear,

It has now become more childish than should be.

Guys, unhealthy response begets another.

May we change the sub-topic.

IS THE WEATHER TREATING EVERYONE'S DAILY PANEL YIELD NEGATIVELY (POOR YIELD) LIKE IT'S HAPPENING IN MY SOUTHERN VISCINITY IN THE PAST 3DAYS?

Been brutal over here for a few days. No sun and light no come even dey, if it continues tomorrow I may have a low battery for the first time ever.

You are right. I see sun while sitting in the office thinking that should be enough. But not on getting home. Had to just wash my panels since they are at easy reach. Yet no improvement...

System may resort to grid, via Dry Contact on cc tonight if not already before I get home.

On the bifacial argument, let me put down my understanding:

Bifacial Tier 1 vs Monofacial Tier 1, same or slightly different prices, Bifacial wins.

Bifacial Tier 1 vs Monofacial Tier 1, significant differences in prize, draw, pick your poison based on price/watt.

Bifacial low quality panel vs Monofacial Tier 1, Monofacial Tier 1 wins for durability, higher efficiency and reliability.

Bifacial low quality vs Monofacial low quality, draw, pick your poison based on expected price/watt.

If all other parameters are the same, Bifacial SHOULD win.

However, let's see real life comparison promised by @Dam5reey1.

na to switch to survival mode. na people wey no get enough panel go feel am more. Freezer still run today despite the rain pouring down since morning

There really seems to be some (intentional) misUnderstandings here

I never said Bi-Facial solar panels are not worth it especially if you got the original ones. My argument was the figures they're quoting and all the unnecessary advantages they say without considering the what IFs.

Another is, you can't compare price on Receipt as total cost of a Bi-Facial solar panel compared to ordinary ones.
Because Bi-Facial solar panel must be mounted in a way that exposes the under surface to some extent, you need spend more on accessories and because at end of the day, if properly done well, you get to see any increase in output around 5% to maybe 15% (anything above 15% is just a temporary extra) best case scenario, you need bigger fuse and cables to account for such, then it's never CHEAPer.

Also not informing people about other nuances such as the extra weight, etc; are the things I tried to point OUT but they became DEFENSIVE.

Most times, when I say things, I need not turn Video creator or start going online to fetch supporting evidence BECAUSE they are things you can easily see around you.

Look around, most Bi-Facial solar panels are installed like ordinary Solar panel which defeats the purpose. Now you end up having unnecessary weight on your roof, for no extra gain.

Now one might say, it's still same size of fuse, cables, and mounting accessories they use for Bi-Facial, THEN I WOULD TELL YOU it's only because you installed them wrongly that enabled you to use same things like ordinary Solar panel.

The group / thread ought be avenue to share ideas and learn ways to keep costs low BUT a few cabals have turned it to something else.

And they keep counting on the fact most people wouldn't want to appear immature and childish hence they keep doing their thing brazenly.

Unfortunately, me no really care. Dem don quiet thinking say I go stop BUT as I still never wan do as anticipated, one of them kukuma tell me say make I keep Quiet.

Battery's down to 51% so I'm currently running on a low power mode. Only fridge and phones plugged in, hopefully tomorrow will be better.

"The foundational strength of the Tiger Neo 3.0 lies in its N-type (TOPCon) cell technology. With a unique advanced structure of the cell and by implementing the latest technologies like ME, MAX, HCP & FP, The Tiger Neo 3.0 has changed the game rules in the PV industry, boosting an impressive cell efficiency of up to 27%, a module efficiency of up to 24.8% with a maximum power output of 670Wp."

eeyaaah
The charge controller powering My work computer is currently reading 70% and I'm sure the moment the Light goes out completely, would drop more BUT I no shake because I still got extra 2pcs of 150AH Ritar batteries on standBy. Na to just switch over to them. Normally, a single 150AH Ritar battery dey last me for almost 2-days on single charge BUT as weather dey very bad since how many days now, na to switch over to the idle ones. Today gan worse pass yesterday.

as for the server room, those ones dey kampee. Me don off Freezer since 3:45pm Na the beauty of overPaneling

Bossdow, why your system dey copy cat mine. Jokes.... 😁

Got home to see 51% precisely... I suspect you tapped from my display.... Another jokes....

Let's progress the discussion from weather condition please... So far so good I should say... The sun power is the answer.

Heavenly, I am looking at you as the Sabinus Knower of our time... Enjoy!

Correct... Any half-smart fellow will hold their peace to see what's to come. This is a place to learn, share ideas and have a different perspective from the norm.

Gloryjoyeux was the first fellow to post his observations about how his bifacials mounted normally on his roof produced much better yields than expected of them in that condition.

Dam5reey1 has also done the same...

If anyone believes both members are lying in order to market, sell products or scam others. Then, they should also be productive and run their own setups to dispel the wrong notion they feel the 'CABALS, MARKETERS, and HYENAS in Gloryjoyeux and Dam5reey1 are feeding all of us.

bassdow:
you already used a clause there "Good Complete" but that's not all, if you buy Bi-Facial solar panel and install it wrongly, then you just using Bi-Facial panel BUT would get be getting Single faced performance all things equal.
What lot of people who use Bi-Facial solar panels don't know all they doing is beautifying their roofs, that's apart from the added weight. They need not even use extra fuses or thicker cables sef because said Solar panels wouldn't utilize the other portion which best scenario is only about 5 to 20% to begin with.
Mind you, sellers also would make you believe both sides gives same reading hence even if you mount it like normal solar panel and one side breaks, you could always turn the other side.

If they had just advertised or made a suggestion and listed both it's strong and weak points, I for no even stress myself BUT they come, praise what benefits them, then trash talk everything else

I am not looking for the 30% gain, I am only interested in the better technology in the Bifacial.. 590w Bifacial can give 590w plus some gains. Its extra and it does not add any cost on initial puchase.

Tdoctor:
Personally,
I think it is good to add a fan to a charge controller that only has passive cooling. Ever since I added a fan to my charge controller with passive cooling, I have been seeing outputs greater than I used to see. Many of these devices are made without any field testing in our climate (how many video game characters are Africans? They don't care about us like that). So, we have to make adjustments based on how we see these devices behave in our climate.
For instance, I had a wifi device I had to add a small fan to because it continuously overheated.
Just dropping my two cents on this.
...
Meanwhile, it is very possible to use a lithium battery and a lead acid battery together, with some important considerations and relays to cut off the lithium and/or lead acid battery (esp. lithium). Many people have done it outside the country with zero issues.

Can you share pics of how you connected your DC fan.

Una just dey twist like Fufu inside Okro soup. issue has never been about Bi-Facial being better or not BUT the misinformation you people put out.

Bi-Facial is good BUT you need mount it well to get that extra less than 20% extra harvest. BUT a lot of the thins now being said, were never said from onSet about Bi-Facial.

Mind you, even half-Cut cells tends to give better harvest than ordinary Mono solar panel. Bi-facial has it's own advantages also BUT when you consider the extra costs, then you decide which path to take.

Issue be say una don too paint pictures so tey even those wey no too sabi dey scared unnecessarily because they've been made it's got to be a particular this or that else you waste your money and not get what you expected. The things I say, I need not wait on anyOne to do Videos to proof otherwise.

Everything got the way it ought be used BUT here, we sometimes focus more on what would benefit us, to the detriment of the customer.

It's one thing to first get certain information out of a potential customer, before knowing what to suggest VS just blindly making suggestions, then quoting astronomically fictitious figures to backUp a hoax.

cutefy:

though I haven't done this personally, BUT if I were to do it, I either tap light from any point inside the chargeController, or if said chargeController has USB port, I use that port or I kukuma just go external by getting power elsewhere.
Most small Fans are 5v and those are more energy than their 12v counterparts.
As for where to buy the fan, go to any electrician, ask them you need the small Fan inside DVD player and they would give you, they mostly would charge you but should be 500 naira or less.
Another place is computer repairers - ask for laptop fan (those are 5v) as the fan for Desktops are most 12v and also bigger.

or if you know electronics store (where they sell things such as Diode, IC, etc), those places are very few but you could get them there also.

if you go meet people wey dey sell Solar, price go wear shoulderPad

I've observed that you have knack for obsolete technology and ways of doing things.

1) It's wrong to mount panel directly on roof, without adequate space underneath for ventilation. So your point on extra mounting gears is null and void

2) you wrongly assumed it will require thicker wire and bigger fuse without doing the calculations to ascertain the wire size it will need. I showed you that wire size will be same for same size of nominal panel wattage. You also wrongly assumed that higher current fuse is costlier than equivalent lower current fuse or breaker.

3) whenever you see superior argument, your first line of defence is emotional attack: you claim those oppose to your ideas are vendors or pretend not to be committed to the cause of this thread, pretending to be "cruise-catcher".

5) when you talk of weight, do you have record of any roof that has collapsed because of bifacial panel weight?

Just as everything in life, there will always be for/against any technology: lithium vs lead/acid, mono vs poly panels, bifacial vs monofacial, copper vs aluminium wire etc. The superior technology will always win overall.

you write full page, no evidence of any sort BUT you want me to bring evidence when I call you guys out for misinformation. You say you Observed, abeg keep Observing Ooo

bassdow:
so as I no come act matured enough to keep mute, you come kukuma tell me.
Why not try ignoring me, maybe, just mayBe, I would get tired.

e funny say una dey talk without viable evidence, BUT expect me to bring evidence. MayBe you haven't observed I don't share pictures or videos. Those ain't my line of work hence no get such time.

Una wey dey quote figures, where una evidence. Even manufactures of the things una dey promote go shock sometimes seeing the confidence and figures una dey quote

Maybe you are not on Tiktok. Many guys here like damreey5 and others post experimental videos and do 5 hours+ of tiktok live scientifically reviewing solar DIY products.
They are doing the doings you are doing the talkings.

Stop unnecessary cho cho cho, do your experiment and post your results...

All these your write up na just noise... This is a DIY thread.... Show working, or allow those willing to put their resources into work for the solar community do their thing without casting needless aspersions...

Are you SURE ?

Because it looks to me like a Sales page. We know say na cho cho cho such as this trim down the lots of adverts una dey spread for here

ask4bk:

Are you aware the Argument is not about if Bi-Facial is better or not

BUT why trying to deceive the general public ?

Whatever experiment or testings or reviews they do, is different from someone coming here to tell lies just to pull traffic.

Once again, if you buy Bi-Facial Solar panel, come mount am wrongly, then you're just better off without it.

Bi-Facial need to be mounted the right way. I need not create videos to show you anything - just take a walk around your neighborhood, and tell me how many Bi-Facial Solar panels you found that were mounted the right way.

Now even when you attempt to mount it the right way, you would incur extra costs, while exposing yourself to extra risks just as wind. This is mostly true when mounting on top of a roof.

Now offline, a lot of you charge very differently for Bi-facial solar panels BUT would come here claiming something else. Just as una dey use style chat with me, me sef don do similar with una.

Once again, except conditions decides, most time You're better off buying normal Mono or even buy half-cut cells. problem be say a lot of rubbish flood market all in name of Canadian solar, Jinko, etc. Now una don dey add bi-Facial to the noise.
una go sell rubbish, come dey hide behind online articles and videos.

Before now, it's used to be Lithium batteries against anything else BUT I said - except you TRUST your dealer, you better off buying LeadAcid / tubular batteries. A quality lead Acid based battery is much better than a low quality Lithium based battery. That one vex una so tey I no even know as that one take end.

A lot of the things you guys say here might confuse users who don't have deep experience BUT for those intending to come onboard, they would totally loose their balance.

I like the arguments so far . I won’t lie.

I believe I understand the final angle of discussion bassdow chose to rest his arguments which is based on how the bifacial is balanced on the roof and the cost that is likely incurred. Most of the initial ones were countered, and I liked that too.

Being a science person and one who has also published a paper too, most of the claims here are hypothesis (both bassdow and the rest) because they are yet to be tested and proven to become a theory or a generally accepted fact. A scientist must be cautious as not to easily accept an hypothesis except an experiment is being done and proven on it.

The findings or results from the experiment can actually differ from the hypothesis (the original sayings here) and if that is the case, such sayings are refuted.

Secondly, some experiments may not have had the best set up required to completely and successfully determine a conclusion (in this case, a marketer here who claims that Bifacial yields better than a mono may have his reasons; maybe from personal experience or testing). But if further experiment is done that finds out more about the original theory from the first experiment, then it requires a “modification”. The popular Bhor’s atomic model modification on Rutherford’s comes to mind.

That a bifacial panel will yield better than mono on a regular position on the roof is an hypothesis, of which I don’t know, but an experiment. So Damrey can go ahead and perform his experiment, it is now left for us to find any experimental error (or magu-magu 😂) to invalidate his experiment or not. Shikena.

And pls bassdow, pls try to keep your arguments shorter. I like them, but sometimes they are too long. But keep them coming anyways 😁.

Good day everyone

I am using Powmr 4.2 hybrid and Haisic 25.6v black one, grid was on (charging was going on too), and supplying the house (load was lights and fridge), suddendly i heard a sound and power was off. Went where my setup was, saw inverter in error mode. Error 9 (bus soft start failed), battery shut down (battery is still shut down, not on)

Please what is the way foward? Location is Benin. Please

Please note my system is well protected With all necessary protection. It was not rainy, just normal grid usage (AC bypass mode) with less than 200w loads.

I have mono and initially ran away from bifacial because the crowd seemed to be against it.

I was also always a Jinko guy because the crowd seemed to say Jinko or nothing else.

But when last I wanted to shop for panels.

590 watts Jinko was so expensive and I found 700w FY way cheaper.

I opted for the 700w FY bi panels and I can tell you that in the same position as my 545 watt Jinkos they do better and consistently match their rated output.

I believe they would exceed the rated output if not for the bottleneck in the form of the charge controller.

To confirm, or disprove this, I would need a charge controller with a bigger throughout capability, that is not a priority for me now but will be in 6 months when I plan an upgrade, I'll report back to the house.

So from personal experience bifacial panels rock

see eh, a lot of the things I say here are things I've done. Even said Solar panel, I get am 2pcs.

Ordinarily, when a client shows interest on something, I ask questions as these helps in understanding the client's needs and requirements.

this argument is like saying a solar panel would produce current when kept in a dark room.
What these people do is tell you whatever they can to make a sale and that works for them most times because we've got more population of people who don't push.

I never said Bi-Facial solar panel is not BETTER BUT in what Circumstance there are times they are not better. Where do you intend mounting them, and how.
Do you even require them when there's half-cut solar panels.
why have we suddenly started speaking like the Bi-Facial is so good it outperforms non Bi-facial ones ?

Even in carpentry works, there are times you don't need a nail but bolts & nuts, other times screws, or nails. Yea you might say using Bolt and Nuts is cleaner, fancier and can easily be removed hence better BUT there's also something likened to sagging whereBy under stress, the Bolt & Nut would break vs a nail that would just bend.

I happen to know this despite not being a Carpenter because I own an electric hand drill and have constructed cages for my chicken coop, and currently even planing on doing same for Snails which I also intends going into. I'm someone who loves doing handy things even if outside my field. I'm also one who don't mind speaking with the local guys just to expand my knowledge.

the things I have said, requires no video evidence. if they doing Video, it's to show that a half-cut cell Solar panel would outperform regular solar panel most times, or that a Bi-facial would outperform regular Solar panel when certain conditions are met. Not that they're always worth the extras.

Just so you know, there's a BIG difference between doing online research to understand a technology vs doing google search just to sound intelligent . Funny enough, since this year, not sure I've google anything solar related

FEGEITOK:

So from personal experience bifacial panels rock

if I change a regular poly or mono solar panel to the newer half-cut cell solar panel, there's no way I wouldn't see improvement. You would always see improvement when coming from the much older technology BUT that doesn't mean you utilizing the Bi-facial features completely. Let's leave all other variables constant.

na person come do work where e install 20pcs of 280-watts solar panels all new for an ice-block making machine. As the thing dey disappoint, and said installer wasn't around at a crucial time, I was called, I came and after accessing the situation, suggested they change the solar panels BUT the man refused say it cost him lots of money already yet the almost 15kwh feliciity lithium battery struggles to charge up above 80% in 2-days which using said machine at same time. All I did was assure him we change the solar panels, if not worth it, he would get a refund (I already agreed with seller to allow me bring them back since they are used and He agreed).

Guess what, I replaced them with a used 350-watts Mono (not even half-cut cells Ooo) solar panels and since then, I've become the Man's favorite. He keeps saying how He didn't understand how a used solar panel would outperform a brand new one. Mind you, Solar panel were the only thing I changed, that's apart adding fuses and combiner box as the previous company (that's what He called them) just connected the entire wires together.

BigDickProblems:
I like the arguments so far . I won’t lie.

I believe I understand the final angle of discussion bassdow chose to rest his arguments which is based on how the bifacial is balanced on the roof and the cost that is likely incurred. Most of the initial ones were countered, and I liked that too.

Being a science person and one who has also published a paper too, most of the claims here are hypothesis (both bassdow and the rest) because they are yet to be tested and proven to become a theory or a generally accepted fact. A scientist must be cautious as not to easily accept an hypothesis except an experiment is being done and proven on it.

The findings or results from the experiment can actually differ from the hypothesis (the original sayings here) and if that is the case, such sayings are refuted.

Secondly, some experiments may not have had the best set up required to completely and successfully determine a conclusion (in this case, a marketer here who claims that Bifacial yields better than a mono may have his reasons; maybe from personal experience or testing). But if further experiment is done that finds out more about the original theory from the first experiment, then it requires a “modification”. The popular Bhor’s atomic model modification on Rutherford’s comes to mind.

That a bifacial panel will yield better than mono on a regular position on the roof is an hypothesis, of which I don’t know, but an experiment. So Damrey can go ahead and perform his experiment, it is now left for us to find any experimental error (or magu-magu 😂) to invalidate his experiment or not. Shikena.

And pls bassdow, pls try to keep your arguments shorter. I like them, but sometimes they are too long. But keep them coming anyways 😁.

The things I said from the onSet, remains same. Bi-facial solar panels are not cheaper hence if not properly mounted, is a waste of money. The price on receipt ain't the total cost. Let's ignore quality.

As per my comments being long, there's a reason students still buy Textbooks even when they got key-points

bassdow:
There really seems to be some (intentional) misUnderstandings here

I never said Bi-Facial solar panels are not worth it especially if you got the original ones. My argument was the figures they're quoting and all the unnecessary advantages they say without considering the what IFs.

Another is, you can't compare price on Receipt as total cost of a Bi-Facial solar panel compared to ordinary ones.
Because Bi-Facial solar panel must be mounted in a way that exposes the under surface to some extent, you need spend more on accessories and because at end of the day, if properly done well, you get to see any increase in output around 5% to maybe 15% (anything above 15% is just a temporary extra) best case scenario, you need bigger fuse and cables to account for such, then it's never CHEAPer.

Also not informing people about other nuances such as the extra weight, etc; are the things I tried to point OUT but they became DEFENSIVE.

Most times, when I say things, I need not turn Video creator or start going online to fetch supporting evidence BECAUSE they are things you can easily see around you.

Look around, most Bi-Facial solar panels are installed like ordinary Solar panel which defeats the purpose. Now you end up having unnecessary weight on your roof, for no extra gain.

Now one might say, it's still same size of fuse, cables, and mounting accessories they use for Bi-Facial, THEN I WOULD TELL YOU it's only because you installed them wrongly that enabled you to use same things like ordinary Solar panel.

The group / thread ought be avenue to share ideas and learn ways to keep costs low BUT a few cabals have turned it to something else.

And they keep counting on the fact most people wouldn't want to appear immature and childish hence they keep doing their thing brazenly.

Unfortunately, me no really care. Dem don quiet thinking say I go stop BUT as I still never wan do as anticipated, one of them kukuma tell me say make I keep Quiet.

My lord, if you can please try not to be the Van Damme and not try to out talk everyone it would greatly help the thread.

Some of us the NOVICES that look up to you guys for knowledge, you don they make the thread look like a secondary school WhatsApp group. And we no go they fit get the knowledge way we need.

I understand you are trying to prove a point, but please allow us see meaningful contributions as well.
