Na so them talk down on lithium until recently that majority is agreeing with us after they have first hand experience.

Heat Dissipation is better, back side still see lights since there are transparent spaces on the panels itself, Glass on Bifacial is 1.5X thicker than mono.

Anyone talking down on Bifacial without using one or providing tangible data is inexperienced and ignorant.

...and who are those suddenly agreeing with you on Lithium batteries ?

If you wan talk, at least try and be direct. Have never discouraged anyOne between Lithium or Lead acid batteries. My take has always been, there's a place for every battery chemistry + except you trust your dealer not to cheat you, you're better off with Lead acid batteries e.g Tubular batteries.

Another is, those who have positioned themselves to benefit from sales of anything lithium related, suddenly started singing all manner of praises even when a lot of them made little to no sense.
They leave the CONs and overAmplify the PROs.

Despite my constant warning on only going for Lithium if the dealer is 100% trust worthy and wouldn't take undue advantage of you, people still follow the flock and when issues arises, the few in here (aka solar cabals) are quick to cast the blame on the customer, or label the sellers as untrustworthy and still blame the Customer for not doing their assignment well enough to spot genuine sellers.

But then again, I stopped disturbing myself because most humans are Sheeps, easily swayed because they got little to no opinions of their own. After-all, e get reason why Religion still strong in this day and age.

Dam5reey:
Most people struggle to understand basic physics, Instead make Dem do practical test, they will continue to push wrong narrative.

Bifacial offers better performance even on the Roof.
And they are even cheaper!

My Bifacial outperforms Mono..

BUT you and I know that even on roof tops, except that space is reflective enough, you're just better off with just Mono that the extra you spend on Bi-Facial.

And it's not just the cost of said bi-Facial solar panels alone, one still gonna account for specific accessories. Well, been waiting for those whose sole business is Solar to come up with Youtube videos of practical tests to show how a 300watts BiFacial sola panels outperforms a 600watts Mono solar panel by 250%

Anybody know where I can get a grid meter with RS485 capabilities

Dam5reey:
A 590W Bificial and 590 Mono are priced similar Bi facial is likely cheaper now.
And all I need is 590W, Bificial delivers on that. I don't understand which extra you are paying for that you cant use. Cause at peak Irradiation Bificial generates more, added advantage for same pricing.

yea they generates more BUT at what ratio ? As for being cheaper, they only appear cheaper, for now, just like there was a time Kerosene was cheaper, then Cooking Gas was cheaper, then CNG was cheaper, etc.

A lot of you preach the PROs, without making obvious things that ought be considered. At end of the day, hardly would you even get up to 30% (haven't calculated this myself though I currently own 2pcs).

Mine is, except there's enough spacing between the surface mount and the panel, or weight isn't an issue. Lots of roofs are not so strong compared to building of before especially on a lot of newly built houses. A lot of those houses prioritized aesthetics to quality hence house go fine, dem go use Gerard / stone coated roofing sheets, but fail to spend as much for the wood underneath.

There are lots of roofs where you don't wanna tamper much to avoid leakages.

Have seen a lot of biFacial solar panels mounted just like ordinary solar panels. I even pity a lot of those panels sef because the way they mount a lot of them, the heat from the roofing sheet gan go fir fry dodo.

if you come reside in areas with lots of wind, like some parts of Ado-Odo-Ota, or Ago-Palace way, Okota, you need be careful so you BREEZE no go help you carry your solar panel go where you no know.

You also end up paying for extras such as thicker cables, fuses, etc, even when such wattage / amperage might never be reached.

Mind you, most times, charging cable for Samsung Galaxy S8 and Samsung Galaxy s3 no be same price - mostly due to class of both phones despite using same cable.

Don't just rely on youTube videos, anyOne can cook that up. Same way they do with Movies and Religion.

do you mean something like "STS Check Prepaid KWH Meter" ?

No too sabi this one Ooo. na once once I see things such as this

Nothing to backup stories, I have shown my PV arrays with data to back it up on Tiktok.

There are plenty STS meters on Jiji but most of them don't have a website with documentation. I need a device that is reasonably cheap with proper documentation for the RS485 protocol.

Trippledots:

HeavenlyBang:
Think it isn't very likely that such a facility would use hacks to handle their solar installation. As long as it's electricity, there's always a risk of fire--doesn't necessarily have to be a case of bad installation.

But yeah, things like smoke detectors and extinguishers are always necessary to mitigate damage if it happens.

Nigerians no dey agree to install smoke or fire detectors until after a fire incident they will now see the essence

Okay, so those Solar panels are really giving bi-facially. I wouldn't argue as me sef no get strength. My stress relieve time is up hence need get back to work. as for your tikTok videos, just talk say you want more engagements.

I guess we should all still be reading newspapers by now and not be on Nairaland, since advancement of technology has now become a crime. Hope you are still using Nokia Asha 200 phone in 2025.

New technologies are being developed every day, and the just because you love the old tech so much, doesn't mean that the new tech is a bad idea for others who use it.

You first complain about Bifacial panels was initially the prices and you were proved wrong about the pricing, you now decided to shift to other excuses. I hope you are currently using the first generation of solar panels in your setup, as everything else produced after that is a scam according to you.

Learn to embrace new technologies and adapt to it, don't hold on to old tech for too long. Nokia tried to hold on to their Windows OS on smartphone for too long when other phone brand were embracing Android OS, where is Nokia today?

if you understood the meaning of that BI , then you would know the answer to your question is a Capital NO

Naturally, I always often discourage clients going for such. The extra cost is never worth it coupled with the fact most times, we mount flat on roof top / car port

Just buy yourself the regular solar panels, go for MONO and be done with it

FROM FOUANI MANAGER HERE IN ABUJA

1. Price of both bi and mono are same at fouani( i confirmed and bought 4 pieces each)
2. It is safe to install bi on a roof top
3. One can use bi on a normal roof

The prices are not same. You probably considering just price of the Solar panels (which are not always 1:1 exactly) BUT what about the installation kits ? Do you also consider those or you wanna install them exactly like non BiFacial ones. Even you, would you charge same fee to install a BiFacial that you would ask for a non Bi-Facial ?

What about other things such as Fuses, cables, etc; abi if you wanna use same size.

At end of the day, you need know what you doing. A lot of people just go with the crowd. There are lots of Bi-Facial solar panels out there with no spacing at all. They just mount them like regular solar panels - how you wanna enjoy the extra harvest.

Even when you wanna install to enjoy the extra which is never close to 30%, you still need invest in installation else you risk making it vulnerable to wind.

See eh, even when I bought a 60A SRNE MPPT charge controller for 60,000 naira, I still considered cost of transportation + cost of my own stress hence at end of the day, the cost exceeded 60,000 naira I gave them.

Funny enough, a lot of sellers don't even spend much on Solar for their own personal use BUT want their customers to do differently.

Mind You, I'm a Linux user so next time, try use Linux as example while me go use FuFu for comparison since true true...

it goes beyond the price printed on the receipt Sir / ma as one needs consider other costs even at that sef.

Mind you, there are tradeOff for why it appears cheaper on Receipts, abi no be companies dey subsidize cost of unHealthy foods so they are much cheaper than Healthier foods

It will be unintelligent to install a bifacial solar panel on a dull roof or any roof other than a white one, cos it will make no difference from the mono panel type n it will serve no meaninful purpose during harvest instead an individual have only successfully added more load on the roof for the roofing structures to bear which might be dangerous for the entire building. However, if a bifacial panel is to be installed on a shining roof, one can not use a normal interlock aluminium for its installation, instead a more technical accessories that will raise the panel at an height on the roof will serve a tremendous purpose in energy generation and that would birth higher safety precautions. So I hope solar panel dealers are not pushing agenda on bifacial panels to the populace. Though in all honestly, bifacial panel is better than the mono types but best installed on the ground for awesome results

I recently replaced my monofacial solar panels with bifacials in June this year, and I didn't need to buy any extra cable, breaker, fuses or whatever. Because I maintained similar capacity range of Panel Output. Installation cost was exactly the same as mounting my monofacial panels.

So I don't get your argument without any facts to prove your points, did you contact any installer and they gave a separate quote for bifacial as against monofacial?

I actually thought you had some basic engineering knowledge. I'll like see your own personal comparison videos between your beloved monofacial panel against the bifacial panels, so we can also see your facts on why it is better than bifacial.

Do you have any data to prove your point? My bifacial panels are mounted on my black roof and I still get >10% the rated capacity on sunny days.

The things you just said are what I have been saying which they keep on evading. The extra costs go way beyond the numbers on purchase receipt for individual panels. One needs consider installation kits which differs from normal installation kits. I could even hang without installation KITs but can't do same for Bi-Facial solar panels.

What about fuses and cables, one got to factor in those also. Abi na the extra weight especially since nowAdays, most people are after spending more on expensive roofing sheets, than on the wood that holds same roof. Let's pretend to ignore other more technical specs.

Most Bi-facial solar panels you see installed, are rarely installed in the proper way; rather they install them just like regular Solar panels.

For the person who said He had to replace his BiFacial with regular solar panel, without changing accessories or cables, it's probably because it wasn't properly installed to begin with. For instance, all things equal, a 300watts Mono solar panel SHOULD NOT use same fuse or cable size as a 300watts Bi-facial solar panel.

How many of them even use fuses sef. what they mostly do is just use a single circuit breaker and that's it.

What wattage n ur location ?

Abia
550-590w

Good day guys
Im trying to get a monofacial panel since I'm installing direct on rooftop within 550 -590w for my Ecoflow d2
I know brands such as jinko,ja solar,zn
But issue is where can I order from
Out of stock on fouani, even cdcare ,my location is in the east
Any help will be appreciated.

You forgot to mention that you also need to get a new specialized inverter for bifacial panels, that will also add to the cost of the setup, lol.

All surfaces reflect light, all. Some more than others.

The degree of reflection has to do with the material, angle and colour of such surface.

People with real world use are telling you that there is more advantage to using bifacial, even while mounted on a roof. I have seen Dam5rey's test, the other person also mentioned about 10% more yield than rated capacity from his own experience. The correct thing should be you doing your own research instead of holding onto an opinion based on belief and no empirical facts.

Boss calm down now, no one is fighting with you n we are all trying to share knowledge here, meanwhile retract n retrieve ur fallacy that ALL surfaces reflect light, like does asbestos roofing n all dark pigmented roofing sheets also reflect light?. So please read n digest my comment above, I never said a properly installed bifacial isn't better than mono during energy harvest but my stand is that for a better result, it's best installed on the ground with a galvanised sheet placed at an angle underneath the mounting structure or on a shining roof but with a more sophisticated mounting racks for better result during harvest

Why would I bother contacting an installer for services I already render myself. Doubt any installer would easily charge same because the work involved ain't same.

You do know you really don't have to add the "lol" part right.

anyways, I have never had issues with newer technologies so long they fix more problems than they introduce BUT issue here, mostly from you guys is, you preach the GOOD, while completely ignoring or completely hiding the BAD part.

Theoretically, bi-Facial Solar panels are better BUT then, you can't just swap them with previous technology without a few considerations which automatically introduces costs.

For instance, they're heavier (currently own 2), they require extra specialized mounting accessories hence one need consider where they're mounting it - if on roof top, it's got to be strong enough and not negatively affect the roof or cause accidents thanks to Wind.
if you paying someone do installations, there's no way they collecting same fee.
how about fuses, cables, etc, you gotta put those also in consideration.

of course there are other tradeOffs but for now, let's ignore those.

Now sum all those downSides; compare it with how much harvest you would be getting at end of the day, then you begin to a sk yourself if it's really really worth it, especially for small scale setUps BUT that becomes a personal decision. Issue is when people now come online to paint a picture comparison of 1:1 perfectness with no downside.
A lot of people would just be buying bi-Facial, and end up using them as regular panels BUT with the extra nuisances e.g weight.

Some seller are even of the opinion that both sides gives same value hence should 1 side break, you could easily turn the other side. And mind you, a lot of people are sheeples. they just go with what they're told, never inquisitive enough; no wonder Religion keeps growing despite obviousness.

Like all things in life, there's always the PROs (Good) and CONs (Bad) side of things; when marketing or making suggestions, endeavor to point out both sides so intending users know what they getting into.

Same thing with Lithium based batteries - they come here to speak so so highly of Lithium batteries like it's got no bad side; then they also speak so so lowly of other alternatives like they got no good sides; all because selling Lithium based batteries to you would add more to their pockets. They've come up with ways to wipe and control the thinking of people so they're literally zombies and guess what, a lot of innocent ones help amplify their claims thinking they know what they're doing because they got evidence - data (fact Sheets and videos) made available by those with beneficial ties to said product / technology.

Once again, up till today, large companies such as Google, Microsoft, etc still use tape Drives and hard Disks even when SSDs now exists and prices steadily coming down.


When advertising or recommending a product, kindly state the Good and Bad sides and how they compare and contrast against previous technologies and see if I would challenge you guys.
