Jumat prayers aren't an extenuating circumstance that warrant an exam to not take place at that time. Please don't forget the fact that there are students from other religions partaking in the exams. I have never heard of anyone complaining about this until muric decided it was an infringement.

You're wrong, Jumah to Muslims is just like Sunday to Christians even though the degree varies, would any Christian dare fix an exam on a Sunday especially his service period?
There's no need bringing the issue of blocking roads into this, even though it is very wrong, there are countless situations too where Christians too constitute public nuisance during worship.

People have been complaining for ages, it is just that social media now brings these things to the limelight.

They won't fix their activities for Sunday for the same reason over 70 percent of the world population don't, because it's the weekend, you know, that time of the week where you get to rest after a hectic work week. Not necessarily spent in a place of worship. I am very sure waec officials are human beings who have families they love to spend time with during the weekend.

and "over 70 percent of the world population" accept and make allowances for other faiths, in majority of the western nations, Muslims are allowed to use their Hijabs in school and even prayer spaces provided so they can pray and get back to whatever they need to do, but our "Civilized Nigerians" think otherwise. We claim Nigeria is a secular state but that is far from the truth, the constitution recognizes and gives freedom to practice religion, nevertheless our rules and customs as a nation are still heavily tied to the colonials and it is well known that the ways of the colonialists is based on the Christian faith.

If there has to be fairness and equity, we have to sit and decide what would accommodate all and sundry rather than forcing Muslims to adapt the ways and customs of Colonials -christians.

so which is more important? spending time with loved ones or worshipping God?
Because what is being asked for is a simple adjustment of the timetable for exams not to fall on the period of prayers, I don't even think they're asking for the whole day, just the time of prayer.

A fan is about 80 to 100w for the regular fans and about 30 to 70w for the rechargeable type. A TV is from 55W (if 32 inch LED) if more the wattage increases, conversely, if less it'd consume less. A deep freezer wattage ranges between 200w to 450w depending on the size, make and model of the freezer and the temperature of the items in it. The freezer draws more current if, for instance, the things inside it are not cold; and the freezer takes less current if already cold.

The favourite low energy bulb ranges from 3w to 20w. I'd assume the lamp you are using is 15w; therefore total power consumption is 45w for the bulbs.

So assuming your total load, I can say you have 300w ( deep freezer) + 100w (fan) + 45w (bulbs) = 445w

You didn't make any mention of the number of hours you plan to use it, so again, I'd assume you want to use it for six hours (between 10am to 3PM)

Energy consumed is 445w x 6 hours = 2670 watt-hours (WH)


If you are running a 24V battery system, i.e. an inverter that needs two 12V batteries to function, to calculate the theoretical number of batteries capacity required we have:

2670wh / 24v

111.25Amps dc per hour draws from the system.

Battery capacity is expressed by how many Amps for how many hours a battery will last - Amp-Hour (A.H.) capacity.


For 6 hours for a 24-volt battery, we will require 111.25 amps DC x 6 hours = 667.5AH


If you are buying 200AH batteries that will be 667.5AH / 200AH = 3.3375 or approximatively four batteries.

I see someone selling 200ah batteries 70k here. Though prices change dependent on make and quality. That means you require 70k x 4 = N280k for batteries.


Now since the calculated energy is 2670wh, you will need some solar panels to replace the 2670wh of power consumed by the devices you run.

A 300watt panel will produce in 6 hours of sunlight 300*6 = 1800wh.

But we know in reality that it will not produce 100% of its rated capacity but rather between 30 to 50% of that. Going by worst-case scenario (30%) we have 1800wh * 0.3 = 540wh

Therefore we will need 2670/540= 4.9444 which we round to the nearest figure- 5 numbers of the 300w panel.

Assuming you buy the standard Chinese clone which ranges between 52k to 60 k you will require 52k x 5 = 260k

In Summary

Battery cost = 280k

Solar panel cost = 260k


I did not add the cost of the inverter and charge controller.

I can only say the budget between 200k to 220k for both.

That makes the total cost approximately 740k.


This may be less or more depending on the quality of the product used and the person running the installation. I was only trying to give you an idea.

Experts are welcomed to weigh in on this


FYI: I did not add the cost of wires, installation of the solar panels, breakers and other accessories as that is dependent on the person(s) doing the job for you. This is just purely an approximate estimate.

Your calculation is somewhat confusing.

You already multiplied the total consumption (445W) by 6, so why multiply the current which you derived from the power for 6 hours by 6 again?

Celebritydevelo:
I see.

It's a project to test my python skill.

then no problem at all, you'll learn some things and a better usage for what you've learnt can come from there too.

Celebritydevelo:
Yes, exactly.

What's your thought on this?

It is nice but sounds more like reinventing the wheel because I can easily take a screenshot of a webpage on my phone or snip on PC, so why use an app ? or are there other functionalities attached?
are you merely embarking on it to test some functions or you hope that the general public would use it?

Celebritydevelo:
Working on a system where you can take screenshot of a website just by submitting the URL.

similar to creating a pdf of a webpage but just in image format?

MountainView , asalimp, Escalze, Vince77 , You said I should mention you when the app is ready. The official video is not out yet. Meanwhile, enjoy the video

impressive, well done.

ugwum007:
Also working on depression prediction app. The AI model developed with Python have already hosted on heroku.

python based webapp on android? how did you achieve that?

Razak5:
Well said.
The bolded is a rule of thumb.

See the item(preferably at the shop)>>>Check the item>>>before payment.

*cheers*

So What happens when I want to buy a laptop from you and my current location is Jos ?
Would you send me the laptop first then I pay after I receive it?

bayo2018:
Serious Help is needed

Report to the EFCC or the nearest police Area Command.

Akinola234:
Hello...

I am about to purchase laptop on amazon...

Please.. I want to know if they used to ship laptop directly to Nigeria.

Thanks

it is better you go through shipping agents, there see many of them in this section. check their topics and reviews.

herveze:
Good day everybody here, pls I am trouble right now because my laptop where I saved all my office documents to do at home is not booting in again and I must submit one of the documents to my boss on Friday morning. Anytime I switch on the system the system will just restart again,i am using HP 4515s laptop, pls any solution

start by getting an external hard drive casing, remove your hard drive from the laptop and put into the casing, then you can access your document.
After which you can get a solution to the laptop's issue.

Elbizzcklinz:
The link is not accessible.

When you say "if". Does that mean there are likely to be other conditions causing the blue screen?

The error is "Page Fault in NonPagged Area", you can Google that, as for the link, nairaland made it bad, just remove the space between the zero and coma. It can either be software (windows issue) or hardware.

check this

The error you it stated is what should give you an insight into the solution of which your RAM could be the culprit if the issue is caused by hardware.

I have a leak from my radiator and i am trying to get it repaired..

Ill let you know when i resume pickups..

Thanks

Pickup another car from offerup then letgo this one after they've fixed it, instead of allowing Chisomk9 to loose deals.

Ok, tomorrow someone else would come to tell us the font he uses.

terrymason:
That's their opinion.
After the panel installation, we always check with multimeter to see the amp and voltage results, which is always perfect.

Ok, thanks.

terrymason:
Correct sir.

Ok, I was asking because many people always advise against twisting wires due to loss of energy.

terrymason:
Remember that all positive/negative head of Mc4 connector has same shape, so it will be impossible to fit 11 panels positive/negative connectors together, when it being connected in parallel way... check the diagram below.

Ok, so you cut off the mc4 and twisted the wires together, right?

terrymason:
Will draw the connection later today...

I'm referring to the ones you cut of their mc4, how did you connect them to the linking wire?

terrymason:
series was via mc4 connectors, while for parallel, the mc4 connectors was cut off to enable us run a linking 6mm wire to all panels...

how do you link these wires? twisting them together or ?

terrymason:
in series and parallel.. Two panels were connected in series before joining in parallel.

directly via mc4 connectors or ?

How did you connect the panels?

Latest isn't always the best.
how many times has "updates" ruined the stock?, if it ain't broken, don't fix it.
