Guys, what are the odds of a roof leak after solar panels installation and has anyone here experienced that?

bassdow:
if you intends using Solar panels, this money no go easily fly Ooo.

Either way, if you within Lagos or Ogun state, I could be of help BUT still, budget 500,000 naira to be on safer side especially if you intends using Solar panels

I can stretch to 500k if it will serve well.
Solar is not in that budget at all, just a basic backup system to augment NEPA power.

I'm in Lagos, I'll be grateful for any help I can get.

7 months in and my lithium battery still holding full capacity even with 2 heavy AC use, electric iron, oven, washing machine and basically every load on a daily. Best decision I made thanks to listening to expert opinions on this thread, meanwhile my in-law don park his load of LA batteries after just a year+ on much lighter loads.

Even the lithium-ion batteries I got for my rechargeable fan has outperformed the 2 LA which barely lasted 3 months for each replacement.

Bottom line is, LA batteries are a very bad investment choice for new and intending users. Use your money wisely once and for all!

bassdow:
then it's possible depending how much backUp time you expects.

Kindly remind us of your loads and those that are essential at Night time.

teejx13:
Key loads:
Freezer of 110W
Laptop 65W
Phone + Light, Fans, etc 150W

I'm okay with 4-5 hours of backup.

I don't mind sachet or used if it's functional and reliable.

budget is ₦400k -> ₦450k.

I don't think my total load is up to 400W continuous.

Oshomo12:
It is not possible with 500k, don't put hope at all.

4 to 5hrs of freezer is a premium taste

1200whr of battery will give u 960whr with 80% DoD and you listed a load of 400whr

divide 960/400, then you will get your backup time, all other things assumed ok nii oo!!

HIGHESTPOPORI:
Buy the itel power tank with 450w panel and save your self stress

dollarnaira:
Get the following:
4 lifepo4 Cells 12v (4.2kwh) =360k or less
Balancer = 18k or less
3kva Satchet inverter = 100k
Grid charger = 40k or so.

Total = roughly 520k

Mind you, the biggest load here is the freezer which you can run alone for over 30hrs. Your laptop will not be plug in all through and lightings only come up at night. Fans will run fully at night without freezer.

With time you will add add solar panels and be power dependent.

Baba use your sense it will work

Edrizz:
What's the essence of using solar without solar panels, "what if" national grid collapse n his freezer is loaded with stuffs, then pressure will now certainly set in to mount solar panel.


Let's try n work with his budget n here's my opinion

100ah 12.8v battery @230k
1kva hybrid inverter 165k
530watt jinko panel 98k
Cable n MCB 30

Total 523


U don't necessarily have to charge with nepa cos of inevitability of funds to buy protective kits against surge

But he had been on the grid with the above loads before his request. But wait oo, which will u choose between 230k 1.28kwh and 4.2kwh of 380k?

bassdow:
from experience, most people who use inverter without solar panels tend to spoil their batteries overTime. A lot of inverters don't recharge batteries well + the fact the NEPA light is rarely regular enough hence they end up doing to their inverter + battery system what rechargeAble fans suffer.

My suggestion would be to use Solar panel even if it's just 2pcs. A budget of 500,000 naira is well enough to handle that. That way, His freezer runs during the day between hours of 10am to 3pm daily.

durodee:
Odds not in your favour

teejx13:
Thanks for this boss.

This looks nice.
I can still look into expanding and mounting panels in the future, just need to organize some other things (not just the money).

I have a question. How fast the can the charger fill up the battery?
is it configurable by charger?

Also, I will work to never drop below 20%, or of there's a way to configure the inverter to cut-off earlier as well to avoid draining too deep.
I want to avoid the issue raised here by @bassdow

BangaRice:
abeg ooo. Where is the bold available?

4.2kwhr for 360k or less.

dollarnaira:
Cells only

teejx13:
Okay. I guess this means the cells will have to be assembled and combined with the balancer.

How will I go about this and the rest of the setup?

Oshomo12:
kindly share with us when you achieve your solar goal with 500k that will power your loads...

cells only for 360k, how much BMS will he buy with it, 30K abi, casing etc unko? no go enter express like this oo

bassdow:
I often find it difficult giving quotes without having idea of max budgets as what we might give might end up not being useful due to costs

for the PV cable (the wire coming from the solar panels on top the roof to your apartment), budget 25m length of cable be it Aluminium or copper depending on budget.

for freezer of 20Litre, I want to presume you meant 200 litre.

for inverter, go for minimum of 3.5kva or 5kva as cost difference ain't much. Feel free to do hybrid or standard inverter. Could be 24v or 48v though I tend to suggest 48v but then it largely depends on your budget as battery dey wait for you.

for batteries, go for leadAcid or Lithium batteries based on your preference and if you trust your vendor.

If not Hybrid inverter, then you need an external charge contorller, go for minimum of 60A MPPT and again depending on budget, budget anywhere from 80,000 naira for NEW or USEd one.

For solar panels, you would be needing a minimum of 4pcs of 400w mono solar panels new or used based on budget.

then budget for circuit breakers and the likes including installation

dollarnaira:
Why is your heart like this?
Casing for this kind stage?
Is like you don't just wish him well at all.
Some of you just believe a system won't work without bms.

His set up will look like this with just an active balancer.
