Regarding solar, this YouTube channel was recommended to me by a kind soul on this very thread

https://www.youtube.com/channel/UCQhnGf9YGnXbbDwPWBUrLNQ

I refer to it not for equipment but for the Nigerian perspective.

I was watching click on BBC1 this morning , there was this high power battery called MOIXA, heard of it? sold by IKEA UK!

erico2k2:

Bia U nor get chill at all Ohhh, nah competition to build?
U wan drag us back to page 500 ni?
I try to see where Egun yab u I nor see more so guy plz stp using the N** word is so derogatory among us black men in a not so friendly chat

You speak both Igbo and Yoruba by forces �

How can i reach you directly, what's your contacts?

Timtol:

Will have to see the plan or a well sketch first.
Thanks

I haven't heard of that one specifically (I've been watching the Tesla stuff to see if pricing will come down by efficiency).

But I'm always keen to learn so I'll go find that episode/battery.

Thanks, mate.

Morning to u all, Happy Sunday Happy independence day ..............

The good in all these is that those who think they would find the Book useful, are asking for a PDF copy.
I bought four units of the Hard Copy and made 'gifts' three of it, to friends.

@Commonsense101: I will appeal to you to not react to the snide remarks of Egunmogaji.
Let it pass-by, l am sure his choice of words was not lost on anyone here but "he is who he is" and l am not taking offence.

@desiji: Here, we are talking about individual and domestic consumption ONLY.
Three phase that you are referring to, is for Grid-tie connections (we all know that the Grid has R,Y,B and Neutral). I dont think anyone here has even generated enough power to fully discharge hsi needs, no tot talk of having surplus to export to the National Grid.
Even the way Nigeria's power grid is, you cant tie into it for now, unlike say in the U.K or U.S

Automatic Current cut-off has nothing to do with ...and is not achieved by neither Three or Single phases.
You are probably referring to the load balancer. and associated cut-off Diodes.

Be that as it may, it is not an issue for arguement, we are all here to learn, right?

Please explain the impact of charging your non solar inverter with generator in the absence of PHCN

Absoluetly No Impact!

Just ensure that your generator is of equal aor higher capacity, than the Fast Charger/Setup you are using or charging.
You will notice this when you Generator starts 'screaming' above its normal self, when you connect or swith the charger on with Generator.

But nothing to worry about.

The Moixa one is similar to Teslas own, both very good solutions and I think well worth it for most consumers. There's a backlog for Teslas stuff for example in the US due to popularity.

With my background though I think I prefer cobbling together my own stuff - at least that's where I am at for now. It may change.

It's always good to share ideas and I'm receptive to that. Unlike asshats that want to shove their unsolicited ideas down my throat. For where?

Thanks.

Great !

Stand, arise and let's celebrate..... No place like home U kw so?

@Daboomb, this is where we don't think things through sometimes, What about a colletive solar farm for a group of individauls or a solar array project for a block of Flats. High in acqusition but cheap on the long run. was even in Naija back in a while was invited to a discussion in Gbagada where some Landlord's were talking of a solar array farm for them , how feasible and at what cost, we have about 12hrs sunlight in Naija why not make use of it.
The today Technological advancement is there to be made use of not also ohing and haing how the oyinbo people do it. I agree due to its acqusition high cost it may seem daunting but if you calculate how much you will save in 20yrs and also not contributing to the burden of the Enviroment it is a win, win situation.(considering the Epilectic PHCN power supply in Nigeria now)
Batteries are the only weak point in a solar setup but with the high rate of Technological advancement, It is also been conquered,
Lifepo4 for, example the Tesla used batteries to name a few. with depth of discharge DoD up to 90% and nothing do the battery! still going on strong with 10years warranty

Articulate points bro,This idea will be possible in ESTATES the downside is the acquisition cost a very welcomed initiative for home owners within an estate to pull resources together to build solar farms to generate electricity and depend less on the national grid,if this can happen in the country all these DISCO,GENCOS will sit up as this will impact their bottom line which may lead to efficiency of the NATIONAL GRID

There are strong plans to be able to convert batteries from cars i nto Home use by various tech coys.happy Days.There is this guy on youtube who made his own power gen with no fuel to run, just initial start up of a motor.SOme Asian DR like that, I will post link if I can find it again.

Daboomb:







There is a 'possible' misconception here, l think.

A million niara is about $2,700.

A Solar Inverter of such range- amount from Sunny Boy is about 9KW (9,000 Watts) and it is a GRID-TIE inverter.
You wont need that in your house if all you need just enough equipment to generte Power for your household usage.

'Grid-Tie' is when you generate enough energy with so much excess that you want toi "sell" the excess to the Utility company, by tieing your own excess generation, to the Public Utility company such that they pay you money for it in return (You are like PHCN, selling Power to the Public).

That Inverter is a special one and different from what the slef-service user need.

Most households dont use more than a 4-5KW Inverters and they are ordinary Inverters as opposed to Grid-Tie ones.

Let me also mention here that we can take advantage of other alternatives aside using Solar Panels.
For example, you can tie your inverter to PHCN if your area gets around 4hrs of elelctricity in 24-36hrs.
All you need is a Digital Fast Charger and you are good to go.

Batteries are actually the most important part of such alternative energy solutions but there are batteries that you can buy in Nigeria that are as good as those you buy in Europe or US (My Batteries are made in Germany but l bought them in Nigeria. Served me for over 4yrs now and l am sure l will draw at least another 4yrs from them...the Guarrantee was for 10yrs)

The problem most people have with batteries (when they say it does not serve them long enough), is over-drawing the batteries.
You need to ensure that your setup has an inbuilt "warning system" that alerts you once you draw your battery to critical level and at that point, you must either recharge it or shutdown.

How long it lasts (duration of operation) depends on what you load (instant Consumption) on it and the combined size/capacity of the batteries you coupled together.

There is a very good book which anyone can buy, read and become a 'champion' on Solar energy and installations. It is so simple that you will wonder why you have not read it before:
Solar Elelctricity Handbook by Micheal Boxwell (cant remember how much l bught it on Amazon, back then).

Buy it, read it and come back here to give testimony


Cost will depend on a few factors like:
What is the Capacity of say, each A.C you want to use and how many will be on, simultaneously
What other equipments will be 'on' concurrently with those A.C?

Basically, you need to do an "intant energy consumption' calculation that would tell you the maximum power you can draw from the setup at any time.
This is what is now used to determine the capacity of the Inverter, the Capacity/number of Baterries required, Number/Capacity of Panels (if Solar), capacity of Charge Controller, e.t.c.
Finally, how long you want it to operate for, at any time, is determined by the installed battery (storage) capacity.

But not to worry, you can start "small", and increase the capacity in small bits, as the Lord provides.
Start with a PHCN-charging Inverter type.
If you outlay Batteries at say 600K, other materials at 400K, you can get a system that will carry all your household equipments, (AC for just a few hours, if you want it to last long) for about 2days non-stop, no-charging.

Add Solar Panels afterwards, when your pocket gets bigger. (Some people l know cant use Solar because they dont have their own building so for such people, the PHCN-Charging option is their only solution and they make it work well for them!)

If anyone is serious about their intention, l recommend they get the book and do a little research.
Everything in that book is for beginners like me and you, in simplified English with very easy diagrams and calculation.

NB: An inverter is just an equipment that converts D.C current, to A.C current (or vice versa) and it doesnot have to be an expensive Sunny Boy.
There are cheaper but less aesthetic alternatives

I need clarification.

I thought Grid tie inverter is an either way inverter. Meaning you can draw from the grid and can also inject to the grid. That means the term grid tie is not exclusive to injecting to the grid. Which ever way you use it, drawing or injecting, it is still a grid tie inverter even if the inverter cant do both.

The onus is matching the frequency and waveform of the grid and secondary is the injection capabilities. Draw you pay, inject and get paid if that option is available by the grid. In our case, its not available to get paid for injecting.

Correct me if am wrong.

I want to add to this

The problem most people have with batteries (when they say it does not serve them long enough), is over-drawing the batteries.

Overcharging is also a major problem for batteries. Most chargers are not intelligent enough to appropriately determine battery type and chargeing it accordingly. Different battery types require different charging voltages and current but when a charger has no user or intelligent control, it treats all batteries the same. What could be good for AGM battery may not be good for flooded or GEL batteries damaging it in the process.

I know 1st hand because my battery died as a result of this. Check the picture below, you will notice the label section isnt straight. If you were to see it physically, the bulge is very obvious. It's a classic sign of overcharging.

This happened because my area has good PHCN supply.

Theoretically, this is a good point but practically in an environment like Nigeria it is too much of a challenge to make any meaningful sense. For such to be feasible you need a strong legal system to enforce legal contracts and a culture of trust. The rule of law and trust are weak subset in Nigeria.

Again you need an economy of scale for a solar farm. So you need a large compendium of Landlords in a particular area, like an estate as someone said. But not all household would be owner occupier, most will be rented apartments and I do not see a landlord expending that outlay of cost for a rented apartment that most landlord have trouble collecting rents as at when due. You expend all that money on solar energy and end up with tenants owing backlog on rent and electricity bill as well.

Now the most important debate on this solar stuff is the future of household electricity. You need to know that in the next 10 years or less, the structure of household electricity will change dramatically. Instead of the national grid supply of electricity to homes, household will soon be buying electricity from supermarkets and corner shops the way we buy water or can beer.

A number of countries including China have announced that they will stop producing petrol/diesel cars in 20 years. So in the next 20 years it is a clear and present possibility that cars would be powered by powerful fast charged cell "batteries" which will make it as normal as a petrol or diesel car. It is only a matter of time before there will be the cross over from cell powered cars to cell powered homes. So you go to the supermarket to buy your home power cell and when finished exchange it for a fully charged just like you do with empty coca-cola bottles or beer bottles in Nigeria: liquid content only.

So private individuals (note: not government) investing all that sum in a huge solar farm without the needed economy of scale and waiting for 20 years for the break-even point might turn out a white elephant project that is sure to be consumed by the disruptive technology like powerful fast charged cell batteries.

I will say the best way out with power supply in Nigeria and solar energy is to go the same way as borehole: Individual bespoke design to suit one's lifestyle. Design your solar outlay to what suits you and what you can afford but settle for the REAL THING and not some cheap Asian stuff that are jokes because of cost. One can design solar just for light bulbs and fans and a good generating set for Air-conditioning and fridge/freezer and supplement the fridge/freezer with the national supply when it is available.

Nicely written.

If we can’t get together on boreholes then I personally don’t see how we can do it with something as intense as electricity and it’s accompanying materials.
