go with mono facial. The bi-facial is only 615w when mounted correctly where it can get the reflected sunlight rays. If you mount on the roof you won’t get 615W. Just go with mono facial either ways.
That's not really accurate . You get more than 615w if mounted on the ground in a way sun gets to the underside. You could get up to 720w or more from this 615w PV when ground mounted and appropriate conditions met.

They too, they use third party shipping company just like the way importers do and now the item is no where to be found.

The third party shipping company is asking for container number and tagging lists.

They told me to cancel the dispute, yet third party shipping company can't find my package, while the third party shipping company in china is saying the package is in there Lagos warehouse.
Have you gone to the Lagos warehousehuh

This is a terrible design. Someone should advise them to improve on this.I remember those days , I use my PWM charge controllers to monitor battery voltage without connecting to PV
Idea is to save energy during nighttime.

Was a faouni today and it's just 615w panel they have. Both BI facial and MONO facial are same price. Which is preferable? Also a transformer base and non transformer base hybrid which is better?
Buy bifacial if you are mounting on the ground.

Buy the other if mounting on the roof.

Good morning my people, it seems lightning has damaged my DC breaker, I woke up this morning to notice that my battery is not being charged by the panels, so I decided to put off the DC breaker switch and then put it back on. Noticed there was a bit of spark.

As it sparked, I saw the input wattage from solar panel go up a bit. After the spark the wattage disappeared. Attached is the DC breaker switch. Would I have to replace the breaker switch? I'm thinking of unscrewing the spd box to ascertain the level of damage.
That's not a DC breaker.

Buy appropriate breaker.

Nigerian electrician hates to ground a house.

It's appalling the level of no protection they put up while wiring the house.

87% of Nigerian electrician needs to go back to tech school for a one month intensive course on electrical protection.

Nothing makes me sad to see multiple houses without basic electrical earth and lightning protection.

I need your insights please.

Can I safely power a 12V CCTV camera directly from a 12V battery (charged by solar)?

I have a CCTV camera that normally runs on an adapter rated for 12V DC, 2A (input: 100–240V AC). I want to bypass the adapter and power the camera directly from a 12V battery (such as a sealed lead-acid or LiFePO4), which is charged by a solar system[b].

[b]My questions:


1. Is it safe to connect the battery directly to the camera’s power input?
2. When fully charged, the battery can output around 12.6V to 13V—is this safe for the camera?
3. During solar charging, voltage can reach up to 14.5V—would this damage the camera if it's connected?
4. How do I ensure correct polarity when wiring?
5. Is it safe to charge the battery and power the camera at the same time?

Any advice, experience, or wiring tips would be really appreciated!

Mrree.d , Dam.5reey1 , dollarn aira , Heaven.lyBang and others.
Try a DC to DC converter to ensure safe stable voltage.

After he buy everything he go come dey proce installer 100k tongue.

Nobody talks about this stuff on this thread.

If you are going to spend on what has been recommended (the recommendation is Valery valid) be will to spend well on a good installer.

Is funny a lot of people will spend good money on equipment the spoil it with cheap installation....

Inverter will damage then you will hear this product is not good
Crossed an installation yesterday. More than 30 solar panels mounted directly to the roof. No roof mounting kit, cables running bare on the roof.


Often a product of "I can do it cheaper" group of companies.

Well, it works. Until it doesn't.

Hello everyone, please how much will it cost to send a used laptop from Germany to me here in Nigeria and which shipping company would you advise me to use
Whatever you do, don't use DHL, FEDEX or UPS. If you do, you stand a very high chance of paying crazy high import duty.

Cheers.

MorningStar and Deye actually are on the expensive side for a lot of us. Something like epEver is much cheaper and has high quality.
Mind you, cost of a small used ePever charge Controller is a lot higher than a brand new high amperage and voltage charge controller from all the funny names out there.
Epever inverters ain't cheap o. In fact in China the price difference between Deye 5kw and Epever 5kw is less than $120

Even when well mounted, don't think the GAINs is worth the extra price
Most bifacial sold is the same price or cheaper than conventional PV. I haven't seen any with prices higher than conventional PV, yet, of the same capacity.

Lately became a Headphone enthusiast, and these are my collections
Urbanista Miami
Bang & Olufsen H4
Sony WH1000XM4
Lenovo YOGA
You have quite a great collection. B&O and that Sony rocks. My friend has the latest XM5 bought by his employer for work. Dude rocks it all day! Features on that headphone is just so much. I particularly liked the hand gesture cup of one of the of the headphone to talk to someone without having to manually reduce your music volume.

Thanks bro, however the QCY HT08, HT05, Soundcore P30i, QCY T13 etc, i have tried them all, they are good on their respective ways but anything with silicon or in ears do give me pain & make me uncomfortable, that's why I'm looking for airpods type earbuds populary known as semi in ears(they just sit in your ears without going in deep)

If it's about bass, i was already satisfied with the Soundcore P30i, that thing thumps very well
Oh, I missed the part about the silicon. Unfortunately, I have no recommendation on that type of airpod-like buds.

dollarnaira:
They should be vertically mounted in an open space. It should be the best orientation. I don't like this technology.
Not mounted vertically, but rather with space underneath, ideally over a reflective surface, to capture reflected sunlight on the rear side of the panel.

The tilt angle should be around 10° to 40°, depending on the region of the country.

Mounting it on a roof wastes the bifacial power gain and unnecessarily burdens your roof with more weight, as it is heavier than an equivalent conventional monofacial PV panel.

Satellite TV Technology › Re: Solar Energy, A Complement To FTA by mctfopt: 4:49pm On May 24, 2025
Sibrah:
most people do not leave room for the bifacial to reflect rays and generate more power. Just dump it on the roof and expect magic.
Stuff is even heavier. Not ideal for roof mount.

Who has used any semi in ear earbuds with the biggest bass possible?

I need one, I've heard good things about 1more Q10, Soundpeats air 5 lite, Soundcore K20i, anyone has experience with any of these earbuds or know any bass heavy semi in ear earbuds, I'm a bass head & will like to get one as in ear earbuds i have with silicon tips gives me ear pain
Try the QCY HT05.

AWESOME bass.

Been rocking one for a year now. Super clear call mics. Mics so good you can make calls in noisy place.

i went to their office myself and checked out both haisic and bread. I'm beating my chest and telling you that bread is a better inverter. Better mppt specs, 60a against 100a, better pv voltage range

Single cooling fan and air vent on haisic against dual cooling fan and 2 air vents on each side on the bread. (This alone means better performance)

I held both on my hands.
Oh, just that I never saw the load handling capacity of Bread. Would love user's review on that.

What's Bread's PV voltage range?

Grid voltage fluctuate between 70v-150v in my area until i wrote an email to Ikeja Electric, though they did not contact me but there is significant improvement. The voltage is between 120v-210v now.
Invest in a good servo stabiliser. Those that trust NEPA with their equipment dey try. I don't trust 'em one bit.

Please, does anyone have any experience with inverter being exploded?

A customer called and told me yesterday that his 5kva 48v Felicity hybrid inverter exploded at about 8pm and smokes were every where.

Though I'm sending someone to his house today to check what actually happened but I tried asking him certain questions to know what actually happened. He told me there was nepa light (low current) but the house was running by the solar. The weather was normal and lightning/thunder at all.

The installation was perfectly done.
Components like MOSFETs and capacitors can go out with a bang.

Nothing to worry about, I've had a few experience of having it go POW! while actually checking some.

Pretty loud bang. Most times it could be a result of a lot of things ranging from voltage surges, cooling fan failure, too much dust on components leading to thermal runway etc.

Once that happens, inverter needs to visit the service centre. But to the uninitiated they may think it's a bomb grin

“I Began Collecting Them Years Ago and Now Have Over 650”:

This Man Has Been Powering His Home With Laptops Since 2016
An ordinary homeowner turned discarded laptop batteries into a powerful energy source that has kept his house running for nearly a decade. This surprising approach combines old tech with solar power in an unexpected way.

24 440 watt capacity panels
Each battery pack is rated at 100 amp hours

Since 2016, a dedicated energy autonomy enthusiast in Farmingdale, New York, has been powering his entire home using more than 650 recycled laptop batteries. His system is installed in a shed roughly fifty meters from his house, where discarded lithium-ion cells are carefully harvested and assembled into a custom battery array. This unconventional energy solution combines recycled batteries with solar panels to create a fully off-grid power system, providing continuous electricity for nearly a decade.

Source: India Defence Review
The one thing I love about the US is the vast land one owner can easily have. Imagine owning a property where you can afford to have a shed 50 meters away from your house in Nigeria.

Just for one second imagine that.

I love it for the man, many love the idea of going "off grid" in the USA for a variety of reasons ranging from independence from the government to saving cash in not having to pay for power bills.

I think there was a particular sale going on at that time.

After that, it reverted to normal.

Funny thing is, the price didn't change grin
Most "sales" in most Chinese e-commerce websites are just an avenue to push sales. Most times the "discounts" aren't real as prices are often inflated and reduced to give a semblance of a discount.
