Ogas in the house.

I currently use Growatt 6000 ES Plus inverter, powered by 8 pieces of Exulted 460W high voltage panels connected in 2Sx4P.

The problem is the highest the panels have given me is around 1600W for something that should be generating 3600W.

Installer is suggesting doing 7 panels parallel since we can’t connect all 8 in parallel as the voltage will be too high for the inverter to take, leading to a fault code.

I’ve not been bothered since I installed it 5 months or so ago, but now that dust is settling on the panel, panel output has even gone as low as 1000W some times.

Please advise.

if you know dust is part of the problem, why not wash the panels and if the location is not comfortable, buy those tiny hose and work in there so you don't have to climb to wash the panels

3600w panel should generate ar least 14000w a day of good sun no matter how hot, because 3600w is for one hour of peak sun.

Check the parallel connections.

Didn't know exulted eagles have their branded solar panels

Once again, even the best of Solar panels, can never give you 90% efficiency let alone 100%.

So long the solar panels have no issue, are properly installed, and using good enough thick cables, and no dust, enough unLight, and quality MPPT controller whether inBuilt or external. Mind you, As the sun gets Hoter, efficiency drops.

Would suggest you focus on total harvest at end of the day and not at the point you peeping at the screen

Of course I was not expecting 100% efficiency. At best, 80% because it’s really sunny over here.

But doing less than 50% even when the sun is brightest is a concern.

I have a 15kwh battery but max I’ve been able to harvest in a day is still less than 10KWH.

I noticed the charging power way before the dust started settling.

Omo I just noticed my 60inches l.g smart tv is 205 watts. That's is much ohh..

That is like the theoretical maximum. You are most likely using less than that unless your brightness, contrast and loudness are always set to the maximum. Get a meter to measure real time power consumption.

Why is your installer doing 2s4p? What is this Max VOC of your Growatt inverter? What is the Voc of each panel? Your connections should be more of series.Your Growatt should be able to take the panels all in series.Or is it not an hybrid inverter? Snap the spec sheet of thx Growatt inverter so we can advise you better.

I no sabi d meter ohh

The TV should have Eco Mode or Energy Saving function. Whenever I'am on battery backup, I make sure my 50" TV is on Eco Mode.

Hello everyone. I'm a newbie looking at having my first installation. So I got the contact of someone who installed for my cousin. Here is a list of what he quoted. Please I'd love you all to help me to know if I'm getting value for my money. He intends buying felicity inverter.
How durable is felicity?
Which inverter would be best to install? I keep seeing itel inverters? Are they durable?
As regards the list, I noticed no charge controller, would that be needed too?
Is the amount being charged not too high for a 3kva setup?

Please house help me. Thank you all.

Most things in that quote are too Cost-excessive!
Infact. the Installer wants to build House from your Job.
Imagine, #16,000 Clamp (#200 each!) to tie down just Six Panels?
Run!

That Amount should conveniently get you a 5KVA setup, with 8KVA - 9KVA LiP04 Battery

Depending on your Budget, buy Growatt Inverter (it does not need an External Charge Controller because it is Hybrid), read all the complaints about Felicity in the last 30pages behind though, some will still advice you to buy it, if that is what they have in Stock to sell but the eventuak decision is your own.


If you need an Installer that is reasonable, leave a message for me and l will share his Number, he just did work for me.

Do you know you get more wattage per price point from smaller panels than bigger panels.

2pcs of 350w at 55k each is 110k for 700w
2pcs of 450w at 80k each is 160k for 900w
Just 1pc of 715w panel is 151k for 715w

Which of these gives more value for money and easier to carry, easier to replace in case of damage, easier to install on roof and easier to spread the load balance across the roof?

Price of Panels are also a function of The Product/Maker.
For example, Canadian Solar costs about 30% more, for the same Wattage, than most of all these generic Ones that dont even give you the full stated Wattage or some of them are just 'pasted' Capacity, by you-know-who.

All the fear about High Capacity Panels are mostly unfounded.
- Small Wattage Panels means more number of Panels and therefore, more possible Point of Failure. If l carry three 715W Panels (255W) and someone else carry Ten Units of 250W (2500W), who is more likely to face a problem of connection point failure, in the nearest future?

- And Roof Space is always an issue with all these small-small Panels, even if it is your House, you still dnt want to litter the whole Roof space with too many small panels, it will spoil the beauty of the House because Roof are part of the aesthetics of a House.

- What exactly would damage a Panel that is on the Roof and working? Whatever can damage a High Capacity, can also damage a low Capacity Panel but one should just make sure his Panels are properly installed, use Thunder Arrester and Earth it properly. 20yrs from today, it is still working.

As long as the Building is Standard and not all those Old Mud Houses or Village Houses, it will carry the High Capacity Panels without any issue.
I am yet to see where High Capacity Panels collapse the Roof of a House.

I've gotten over 90% output from my 550w panels so I don't know what you're saying.

Please busy minds how many litres of water frezes into the big size of ice blocks commonly sold 500 naira

you would get more accurate response when you ask those in the business. If you don't know anyOne in the business BUT knows where they sell such blocks, ask them the question first, and when they can't respond due to not knowing, ask them where they buy from so you could ask the person. reason you need first ask them the question is so they don't think you trying to byPass them and buy directly from their supplier.

The problem with that clamp Is he might be quoting for the actual PV clamp, but might end up getting #200 clamp .

So we can only speculate.
Besides all the wires he dey write up and down what are they for?
180k should cover all the wires needed.

Ok

Excellent analysis. It is very convincing. But the technology of these higher sized panels are usually better than the smaller ones, such a single 700w will give significantly better output than 2 units of 350w. Also, most solar panel companies that known to produce quality panels do high sized panels these days.

Although I doubt I will personally go for anything less than 590w though.

But the thing is, landlords, roofers and carpenters should begin to design roofs and select roofing woods and sheets with solar panels installation in mind.

My roofer measured my roof space and gave me a quotation based on 0.455 aluminium thickness. When I asked him why he arbitrarily decided on that low thickness level, he just said his clients always complain of price when he quotes higher thickness levels, and that the 0.455B can still be successfully installed without leakage, "sey dem go just dey waka small small on top am as dem dey install am". I just weak. I had to tell him solar panels will be installed on them and we had to eventually go for 0.55.

Roofing wood nko? The guys at the sawmill will first quote solo (half) wood for you because they will make more money and it will be slightly cheaper for you. You will see a supposed 2x6 wood looking like 2x4. You have to insist that you want full wood across all the sizes so that you can have a solid roofing Base that can withstand any kind of wind and solar panels. And the difference is not even more 300naira on each wood

The peace of mind will always justify the extra cost

To best of my knowledge, theres no difference in output between 2pcs of 350w halfCut mono vs a single 700w halfCut mono all things equal.
except you comparing between solar panels of different grades.

As for that roofing sheet matter eh, even those at the factoring, if you no carry guage go, that 0.55 no go still complete. For the wood sellers, dem go still try mix am up for you. even the one wey no be SoLo (full) no go still complete and if you talk, dem go tell you say na so e dey be nowAdays. dem go try make am seem like standard. don't know about sawMills outside Lagos and Ogun state sha. To even see wood wey complete 10feet na grace of God. Even the popular 2 by 12 no complete 2 by 11 sef; na mostly 2 by 10.5 . You end up buying more just to achieve your aim.

Please advise.

Your installer was wrong.
8S is the way to go. The inverter also supports 2 mppt inputs so you could do 4S on each input( although that would be a waste of cable IMO)

He originally did 8S but the voltage was higher than the inverter could take.

The panels are high voltage panels.

Open Circuit Voltage (Voc) of one panel is 65.71V, i.e 8 panels will give 525.68.

Meanwhile the inverter has maximum Photovoltaic (PV) input voltage of 500 VDC

Take out one panel.

HeavenlyBang:
Take out one panel.

Even 7 panels could still be much as that gives 459.97v which is still very close to the max. We even calculated with 65.71 without giving extra room. Me for say make he kukuma use 6pcs which gives 394.26v which is above the recommended normal 300v.

Another is, as una dey plant high voltage DC on top una roof, hope say una dey take the necessary precautions ?

300vDC wicked pass 200vAC . Some installers still dey even do joinJoin + Celotaping of wires. Also earthing is adviced to protect your investments Ooo.

The only way to use the complete 8pcs of solar panels, na to involve high capacity external MPPT charge controller.

Alternatively, if there's room for extra solar panel, He could buy extra 1 or 2 pcs of solar panel and alter the config.

Next time, make una dey buy Solar panels after buying hybrid inverter / externnal charge controller. Person ask me to give am prices few days ago, as the talk dey move like palito Radio signal, I tell am say make He buy Solar panels first as I need am to know which breakers and the likes we go use.

HeavenlyBang:
Take out one panel.

Simple
It's waste doing 2s4p.Yhen change your installer afterwards for him to even do 2s4p with such inverter

larger panel are way better most larger panel come with premium technology, do you know what is TOPCon (Tunnel Oxide Passivated Contact) or N-type panel technology, no 400watt or 500watt panel comes with is type of advanced tech, it is always better to go bigger if 900watt panel they use am it better off than those small small panel, one big panel nor go heavy make e heavy reach bag of cement

fuckboys:
yeah now imagine the bro who got 6pcs of 715w panels, I would have gladly done 10pcs of 450w panels.

10pcs of 450w panels is 4500w at 800k
6pcs Of 715w panels is 4290w at 906k

A savings of 100k and more wattege.

Ajeh we no Dey think for this hard economy.
