Its really interesting.

We just commissioned a mega gas station adjacent to Lagos Business School in Ajah and it is fully solar powered

No single electricity from the national grid.
All ACs, pumps, lightings and equipment all get fed from the solar panel.

It cost is millions of naira

We have 48 *3 batteries. Installed i.e 144 200Ah batteries and 93KVA total power available at the station

Hi, nice thread. I had mine recently installed. 2.4kva with 2 btl sollar batteries and 1_200wats solar panel but the truth is i'v never enjoyed it since day one as I stay in d east and I paid for for transportation and installation all d way from ibadan and yet the thing has been a real pain and regrets ever since. Imagine leaving d house since morning and coming bak and d so called solar doesn't last 30 minutes with ma laptop, ceiling fan, ps4 and one or two bulbs on(with out load, it reads 12.7 and when fully charged with gen it reads 13.1 but as soon as u power anything it goes down to 12.5 and below drastically). It's so disheartening. Pls what's d way forward

modik:


What is the cost implication ie. Installation and periodic maintenance costs?

Donaldomo:
With the picture u posted, I bet say that you work lacks d perfect touch of an expert. On d other hand, d nature, type and no of batteries used may have contributed to ur predicament with d system. So I urge u to contact a correct expert to look at the system properly for accurate diagnosis. So can work well in Nigeria.

is it a must to use battery when using solar?

Flips:

Please I will like to buy a solar inverter (3.5kvA) + 4 batteries. Do you know a reliable seller(s) in Lagos?
Where did you get yours if I may ask?

kekakuz:
was about to but the mtn inverter until I heard it can't even power a laptop

Kelechi2020:
Following strictly....i would love to know the cost implications though...

Emeka71:
We use up to 24 solar panels with Trista Inverter and 6 batteries . I shall snap them tomorrow .

Nice thread
I'd like to know, how many typical household appliances and a panel power.

DMerciful:
Alternative power sources like inverter/batteries and solar are for powering light load esp for convenience. They cannot economically replace public power supply when the load becomes large. For 3 bedroom flats , 5 energy bulbs is enuf at any particular time, 1 freezer is enuf to run for 5hours per day, 1 led TV and prob 2 rechargeable fans(they are more energy efficient). A 300w* 4 solar panels, 40a epsolar charge controller, 1.5kva sulkam inverter, 4*200AH batteries and you're good. If you need specifics...hala me

YoursGEJ:


Would the setup you recommend here be suitable for a 4 bedroom house with one 50 inch LCD TV, one fridge, 8 bulbs, 2 laptops, charging 8 mobile phones?

I would like to be completely off-grid (24 hours) so I'm thinking I could get a 2kVa or 2.5 kVa inverter instead of a 1.5kVa.

Also, can you suggest what each of these components should cost? I no want make them cheat me

ekpotek:
Got one installed in December 2015. Cost me N250K including installtion. Consist of
130watt mono x6 panels N120,000
35Amp solar charger controller N15000
200Amh deep cycle batteriea x2 N100000
3KVa modified sine wave 12v inverter. Systems still workiing and powers my big fridge. Get up to six hours of power supply after sunset. Saves me about 10 litres of petrol everyday for my generator.

petekayo:
Where can I learn solar panel installation?

Perfecttouch:
nice thread but analyzing with price attached will have helped greatly. Pls do that for would be buyers like me cos I need to be convinced really cos I still don't believe in this solar thing.and if am to use it with 1hp air condition,what and what will u recommend? Pls explain in a lay mans term

sEGXY2:

How much would everything amount to?

ibietela2:


How much did it cost

Lanjonath:
If I may ask sir, how many solar Panels do you use with the charge controller?

@ SycophanticGoat
Please you didn't tell us the appliances your inverter successfully powers.
Thanks.

What is Price of 300W/24V solar panel dat time?

What is the Brand or Manufacturer ?

Can you give Merchant or seller info & location?

First thing first, when choosing your Solar Panel, if you can not get 3-junction PVC , then buy only Monocrystaline Panels.

You need not to spend so much to get Solar Generator to Power your Electronics.

Original Mercury Deep Cell Battery made in Korea works well for me.

Unless you need power in the evening, you can preferably buy Grid-tie Inverter which is always all in one as it as been integrated with Maximum Power Point Tracker Controller to enable you get the most out of your Solar Panels. BuybMonocrystaline Panels always only.

You can still use battery with a grid-tie inverter mind you. Butbif you are on rigth budget, then G.T inverter will save you cost at the expense of no night power.

MPTT controller integrated in grid tie inverter makes sure that if your Panel is rated at 300w for example, you will at least be getting a minimum of 250 Watt of Power from your panel during the daylight.

Make sure the inverter you will buy have proper copper wound transformer and is as well integrated with Overload Protection, Short Circuit Protection, battery Low Voltage Protection.

I bougth my Panels from China as well as my Pure Sine Wave Inverter.

Pure Sine Wave Inverter is what you should always go for to keep safe your electronics from possible malfunction and fault.

You can buy your Pure Sine Wave inverter on Aliexpress. Mine is name I power. It is built to withstand Overload, reverse Polarity etc.and I have tested all this Protection levels and it works fine. No damage at all. When you mistakenly overload it for example, instead of it to affect it internal component like MOSFET, the inverter will Shut down on it own. Immaginne that!

You can buy your Panels from Chinese on Alibaba.com

Just negotiate with the sale rep per watt starting fro say 10Watt. But prepare he or she ahead to agree to the fact that the more wattage you buy, the lesser the price.
But presently, most manufactures are selling Monocrystaline Cellers per Wattage between 30cent to 55cent.


Solar Business is the next big highly lucrativevBiz you can go into now. You justvhave to avoid greediness in the biz to make it big time or do I say attract people at large to buy from you.

One Package you can bring in now is 120Watt Folding Monocrystaline Panel with 150W Pure Sine Wave Grid Tie Inverter with 5V 2A USB port. This Package is for Students.

You can even remove the inverter and go straight for Integrated Universal Laptop DC to DC Charger of 150. The integration therein implies that the DC to DC universal Laptop Adapter will have on it board MPTT Circuit which will be feeding the main Circuit of the Universal Laptop Adapter Circuit.

So Buyers of this Package will need no Battery at all to use the folding 120watt Monocrystaline Panel to get there Laptops Charged during the day anywhere they are.

The panel will have a shock absorbing carrier bag to ensure Smith mobility. It Advance universal adapter will have the major tips of Laptop brands like Accer, Samsung etc.

You can get electronics engineering company to newly manufacture this type of laptop adapter for you.

The adapter can also be made to have 2 USB output of 5v/2A each for fast charging assurance.

If you have the money go into this Biz now forget electronics as people lacks constant power supply to power there phones let alone other bigger ones.

Be wise. Be a problem solver not Problem creator.

For the items listed, even 1.5Kva will do the trick but I will always advice people to go for higher inverters in case they'd wanna increase load in the future. Your TV should not be more than 350w, if the bulbs are energy efficient then let's peg their total wattage at 40w (some bulbs are as low as 3w), laptops usually are rated about 50-70w. Let me peg yours at 70 each, means total will be 140w for two laptops. Modern fridge should not be more than 300-400w. Total power rating is about 940w, let's say, max of 1,000W (1KW). Dividing this value by 0.8 will convert the Wattage to Va. This equals to 1,250Va (1.25KVa). Adding 20% for surge, we will have 1,500Va (1.5KVa)

In terms of battery capacity needed, will get back to you..

For cost..

Batteries cost between 70something to 100K for Indian products but will cost higher for American brands.
Inverter (2.5KVa) will cost about 60 - 90K

YoursGEJ:


Going with your calculated load of 1000W, does that mean I need 250W*4 solar panels? Looking forward to hearing about the batteries also

sjahdey:
Very interesting topic.

How much power do you generate?

What electrical appliances do you power with your system?
