Nice one. You did well

But na MONEY!

Alphamentips:


Nice one bro. I'm a bit of a handyman too but this seems a bit extreme for me. I'm thinking about getting a 1500 Watt home inverter as I no fit de house w/o Ac

So in my case, like how much do you think I should budget for both inverter, solar panels and batteries? Workmanship fee excluded?

I can see 1.5kva inverters online ranging from 13k to 20k for solar inverters and put to 80 - 200k for normal ones. Which is better?

I can see chargers online for 9k - 12k.
And finally, how many Watt solar panel should I buy?

Pure sine wave inverter is better. Best for inductive load

lasthero:
Total cost:

Battery : 85k
Solar panel : 30k
Inverter : 35k

Total: 150,000 naira.

I bought wires 2k

Making 152,000.

My observations so far
It takes 5 to 8 hours of sunshine to charge the battery from 0 to 100% depending on the sunlight intensity.

And guess what guys. When all the house load are on it, it lasted me up to 8 hours to use up a single charge. But when I put of the fridge, the 45watt fan and when my laptop isn't in use, it takes more than 12 hours and that's exactly what I needed.

Burning 8 to 12 hours on petrol daily will send me back to my village.


Thanks for coming to my Ted talk

Nice and commendable. Please kindly work out the payback time by dividing the N152k by your usual daily electricity cost. If you can do that calculation, you can then start counting if you got value from the investment or not. For example, if the battery and/or the inverter pack up before your payback time then it's not cost effective
As at now, it's too early to say if it's money well spent. I commend you greatly though.

Whatever you buy, make sure it's a monocrystaline panel. I bought 6 300w ones on Saturday and I'm currently evaluating performance

Mods, I don't know the right thread to post this. If romance section isn't the right thread, you can move it to the appropriate section.


Moved into a new apartment and realized the light isn't too good. Average of 6 to 10 hours per day and sometimes, there won't be light for like 3 days on a stretch.

I do freelance, love watching movies, I have a small fridge which serves me cold water, I need fan to cushion the heat. This implies that I need a constant light and with the epileptic light situation around, I felt I needed to do something.


My first thought was to get a generator. Average 1kva generator cost 80- 100k. I will have to be buying fuel, buying oil and also servicing the generator regularly.

I almost bought a new generator from jumia during the black Friday sales until I heard the rumors that fuel will likely to be sold for 320/ litre in 2022, I had to abort the generator plan and seek for alternative.


Then the thought of inverter came in. To figure out the specific watt to purchase, I first analyze the power rating of all my electronics.

1 dc led TV - 12v 3A which equals 36watt,
1 gotv - 12v 1A which equals 12wat,
1 dc standing fan in living room of 12v 2A which equals 24watt,
My laptop of 18v 2.3A which equals 41.4 watt,
1 table top fridge of 45watt,
6 energy saving bulbs of 5w each in entire apartment (bedroom, living room, toilet, kitchen, corridors, which equals 30watt
Phone chargers of 5v 2A which equals 10w.
1 wall fan in the bedroom of 45w

When I summed all the power ratings, I arrived at 243.4 watt in total.


So with miscellaneous appliances like woofer and the likes. I concluded And settled for 500w inverter.

What lack of electricity has caused us in Nigeria it's too bad

Bro the sine wave of the inverter is not deep more or less modified so I would not suggest using it for some appliances using motor like fan

You are right about the wiring been neater.

The socket is a change over plug just like the one we see in barbers shop. I run main light to a socket that serves as nepa source and also have the inverter socket for inverter plug.


The only heavy load I have is a table top fridge which is energy savings (45w).

As for the visitors , I hardly have any. Just a single guy living alone and my interaction with neighbors ends at the compound.

The charger and inverter are all in one as shown in the picture and not separate solar charger and separate inverter as obtainable in most houses, so it was easy for me to connect. The only challenging part of the process is placing the panel on the roof which I was able to do with the help of ladder and rope.

What's the critical importance of this? The person that installed for me kept insisting that he must earth it irrespective of whether the building was earthed

wow this a real eye opener, I go sell my generator very soon.

I will upload mine later, nepa want to kill me here in warri, so I opt in for inverter, planning to get another on, I will b using at home

binladen:
Good job, kindly give us update on the state of your laptop battery in 3-4month( if it ok now), the state of the GBM in 6-9month.

Assuming a Pure sinewave inverter, would there be any impact on the laptop Lithium ion batteries?

Well, since you are the one that did the installation and not the electrical guy, you must make sure you follow the basic rule of electronics. And that is, to make sure ALL THE CONNECTIONS ARE VERY TIGHT.
Nothing destroys electronics more than a lose wire that is just lose enough to allow an electric arc/spark to keep jumping across wires. That spark is called Plasma. It is neither a solid, liquid or gas. But it is as hot at 10,000 C. A tiny thing will burn and melt wires and create bigger sparks and more heat till the whole connection will burn.
I hope there's a point for Nepa to charge the inverter and batteries as well. Because you'd be surprised that you won't always get 8 hrs of Sun, Mon - Fri, January - December in this Nigeria.

This one go stingy die

ignis:
Please can anyone help me with this in kano or minna?

In the North, you guys will be balling with this solar setup, especially now during dry season.

Thread bookmarked. Nice one lasthero , as i type, we never see light for 4 days now, my gen has been on since 9 am till now. I only turned off to refuel around 1 pm, I use on average 10 liters of fuel daily if no light and sincerely, it is really not good, plus I feel bad about my gen disturbing the whole house even tho everyone has their own flats, but still, even me, I enjoy the peace when I turn off my gen. This will definitely be what my first agenda mmediately after the holidays.

Eh, we took white man's technology (phone, computer..) but forgot to take white mans electric power supply.
Now everyone has gadgets and no electricity to power the gadgets.

For me it looks like money well spent for my use case. NEPA slapped me an estimated bill of ₦150k/month and loss of revenue of ₦277k (stupid landlord did "Free Rider connection" and lied about it). Paid ₦780k for the setup which is about half the total bill I will pay for a year at ₦150k monthly

I need to save this page, I will need something like this next year (2022)

This is quite helpful!

This really helped me a lot.

Englandboy:

Would still charge, just a slower. My own started charging around 7am. On very rainy days, of course charging may not occur. I'm currently working on having a small wind turbine to augment during rainy season

Please send me the links to where you bought them please

i got this setup already but without the solar panel. i just charge it with light when light comes. below is my setup. 200 amp hour battery

Nice one bro.

A single usage must not be lower than 70% of your battery if you want it to last. Well, it depends on your battery as some can still take 60% to 65%. If you keep using your battery below the level specified on your battery, it will kill it fast.

So, every night you use it, make sure it doesnt go below the recommended level which is always btw 60% - 70% of the battery.

Goodluck bro!

You did well. Na only sense person de take survive for this country.
