₦airaland Forum

Yesterday I did something eye-opening with a friend. I sat down with a pen, paper, and calculator to check how much he actually spends on fuel. His gen drinks fuel like a fish, but he never bothered to count.

Daily, it’s like ₦3k here, ₦4k there. End of the week? Almost ₦20k gone. By end of the month, almost 80k was gone, he almost fainted. That’s a bag of rice or school fees deposit, burnt into thin air, literally.

And the funniest part? The gen still has the audacity to knock sometimes, like it’s doing him a favor by starting at all.

At this point I’m asking myself, “is this a relationship or financial slavery?” My heart especially goes out to business that quite literally cannot do without 24/7 light. They have to choose between four evils:
1)Expensive band A
2) Daily gen fueling
3) Solar system installation, which can be prohibitively pricey upfront, i won't even lie.
4) Shutting down business

The truth is, some of us cannot afford to not use generator every blessed day, just like my friend.
So, how much are you spending on fuel? Maybe I’ll feel better if I know I’m not alone in this.

Truth is, late-night darkness and noisy generators are a headache. You spend money, yet you’re still in stress. Solar, when properly sized and installed, simply removes that cycle. No “hidden costs,” no chasing fuel, no shock when bills come.

If you’ve been putting it off, maybe this is your sign.

Last Sunday, I visited a friend who runs a small frozen foods shop. Halfway through our chat, power went out. His first words weren’t “how do I fix it?” but “how much fuel is left?” Imagine that, your business model tied to a erratic power supply.

That same evening he confessed he’s tired of hearing customers complain about half-melted stock. It’s not just a matter of light: it’s trust, reputation, and survival.

We did a proper audit for another shop like his two months ago. Correctly sized panels, batteries with depth-of-discharge accounted for, and zero hidden costs. Result? They no longer shut down when the neighborhood does. Customers stay happy, stock stays fresh, and the owner sleeps better.

The point is: solar isn’t about chasing trends, it’s about peace of mind when everything else is unreliable.

Ever notice how the generator guy never runs out of work? Always fixing the same machine, always collecting more money.

Solar done right ends that loop. One client told us their fuel spend dropped in half after we set up their system, and six months later it’s still running like day one.

Solar is not just about panels and batteries. It’s about sizing, honest quoting, professional wiring, and after-service support.

Rhaspody:
6kva growatt 650k

15kwh battery 2.3m (x2 if you want)

Panels 650w x 12 1.9m (depends on brand)

Materials and workmanship 500k to 700k

This is a rough estimate. Can get the battery lower if you import yourself.

I agree. That's a well-informed estimate.

So you want to go solar? That's a good call, and congrats in advance. So, let's help you make it smooth as possible so you can avoid heartaches and hidden costs your installer may never tell you. Let me break it down.

1. Transport cost
When you see a quotation, you assume it covers everything. Wrong. Once you've decided to pay for you solar power components, if you don't see "transportation" in the quote, ask.

Why? Panels are bulky, batteries are heavy, and installers don’t like driving beyond their comfort zone. If you live outside the city centres, the fee can jump. Even inside Lagos, once you say “Ikorodu” or “Mowe,” they instantly add money. Some installers don't tell you this until it’s time to deliver, and you’re already emotionally locked into the purchase.

2. Accessories cost
This is another shock most first-timers face. Full package should be “full package,”. Not after mounting your panels and inverter, the installer suddenly starts saying “We still need breakers, SPD, proper cabling, isolator, combiner box…”. Trust me, you need all those things, so don't ever try to skimp on them. So asides from your inverter, panel, and battery costs, ask for accessories cost if you don't see it in the quote.

3. Cleaning and maintenance cost

Nigerian dust is wicked. I once visited a friend’s place in Kaduna, and his 6 panels were dull grey with dust. He hadn’t cleaned them for 6 months. Guess what? The output had dropped a lot. It wasn't charging his batteries as it should have and he just thought the inverter had become weak. Just a thorough panel clean restored it.

You’ll either pay someone to wash them or climbing your roof yourself with bucket and mop. If your roof is high and angled, you have no choice but to pay professionals to clean it every few months.

It sounds small, but neglect it and you’ll be wondering why your “5kVA system” suddenly struggles to even run a fan and TV.

4. Replacement Cost
This is the one that makes some people shout “solar is scam.” Panels can last 20+ years if good quality, but batteries and inverters? They don’t forgive carelessness.

Flooded tubular batteries, even when pampered, last about 4–5 years. Lithium can last longer, 8–10 years, but they cost nearly double at purchase. Sooner or later, you’ll be faced with replacing them. Today, a 200Ah tubular battery goes for ₦300k–₦350k. Multiply by four, eigth, or even 20 pieces and you're looking at millions just on replacement.

Same with inverters. Good ones might last 8–10 years. But if or when they fail due to whatever reason, the replacement cost can be expensive. So i advise you to get a good inverter that'll last.



If you’ve already done solar, which hidden cost stung you the most? If you’re planning, which of these opened your eyes? Let’s talk, because people only share the sweet side but hide the bitter bills.

Buying solar in Nigeria is not as easy as many people think. Most first-time buyers get carried away and fall into the same traps. Here are the common ones.

1. Not sizing your load properly
Many people buy solar without knowing their exact power needs. They just want “light” and think the system will run everything. Then they discover the inverter trips when they plug fridge or pumping machine. Before buying, write down every item you want to power and how many hours you need it. Without this, you will either underspend and suffer, or overspend and waste money.

2. Falling for cheap products
It is very tempting to buy the cheapest inverter or panel in the market. But most of those low-cost products don’t last. Panels lose efficiency faster, and inverters develop faults too quickly. What looks like savings at the beginning usually turns into another expense within months. With solar, quality pays in the long run.

3. Poor installation planning
Some buyers just tell installer to “fix it anywhere” without checking roof direction or shading. A badly positioned panel can cut power generation by half. Many also don’t plan where to keep batteries, leading to overheating or damage. Planning the installation properly is as important as buying the right equipment.

4. Ignoring after-sales support
First-time buyers often don’t ask about maintenance or warranty. They pay and assume everything will work forever. The truth is, you will need support at some point. If your installer has no proper after-sales service, you will be stranded when the system develops issues. Always confirm support before paying.

5. Mixing wrong batteries and inverters
Not every inverter is compatible with every type of battery. Some inverters cannot charge lithium properly, while others are not designed for tubular. Mixing the wrong equipment leads to battery damage and wasted investment. Make sure all parts of your system are matched correctly.

Conclusion
Solar works well in Nigeria if you avoid these mistakes. Do your load calculation, buy quality, plan installation, confirm after-sales support, and use matching equipment. Ca.ll u.s for the best solar installation service with peace of mind.

Captainjack100:
6 million will get u 17kva working solar and 24 hours light for a three bedroom

I'm not saying it won't but how? I'm really curious.

Let state a fact: If you intend to power these two types appliances, namely ACs and fridges, then you need to be very meticulous as you intend to go solar. But let's focus on ACs for. Can solar power AC? Of course.

But before you give your money to that person, here are some things they may never tell you if you want to do it things right:

1. Inverter ACs are your best friend
Inverter ACs are better than old-school ones. They run quieter, use energy more wisely, and never go full blast on startup. A 1 to 1.5 HP inverter AC usually runs around 800–1,600 W and draws up to 2–3 times that at startup (way less than 6-9 times startup surge of regular ACs).

So if your inverter can’t handle that sudden spike, even for a few seconds, you can't use an AC. Sorry.

2. Inverter sizing must include surge capacity
A regular 5 kVA inverter might sound enough, but you need one that can absorb startup surge, especially if you intend to power more than one AC in your house. We recommend going for an inverter that’s 20–30% higher than your AC’s peak demand. If you don't know where to start that's okay. Reach us for a free consultation via the WhatsApp contact on my signature.

3. You need serious panels
To keep an AC running, especially in hot Nigerian afternoons, solar panels must produce way more than the running demand. A 1.5 HP AC needs ideally 3–4 kW panels, to give room for inefficiencies and heat drop-off. Some installers just tell you to install panels without taking into consideration your AC's demand, and then act surprised when you complain later.

4. Batteries must match energy appetite
Your small battery might light bulbs all day, but an AC is a heavy appliance. It will drain that battery fast. Tubular batteries do okay, but only if their capacity is enough and they're well-maintained.
Lithium batteries do better (longer life, faster charge), but cost more upfront.
AC running on solar without first calculating the correct battery size is like planning to travel interstate on 5 litres of fuel. It’s not going far.

Hope you learnt something?

tanigororo:
Nice analysis, how about other silent costs not included in your calculations:
Cost of going to buy fuel?
Cost of Generator Maintenance?
Cost of buying the generator itself?
Sanity Cost nkọ?
Noise Health Cost?
All these carries financial cost too.

Funny
That's left to the sppecific situation of each person.

At the end of the day, it’s not really about solar itself. It’s about control, image, and the fear that tenants will make permanent changes they can’t undo neatly. Some the other hand, are just an extension of your village people.

It sounds simple in your head: “let me just buy solar, wire my flat and live in peace.” But the reality is, many landlords don’t like it when tenants start doing permanent solar installations. See, I've once lived in a compound where the rule was, never stay out past 10pm. Funny as it seems, nobody dared break that rule, because, where you won see another house rent. It was cray!

Here’s 10 Reasons Why Landlords Hate When Tenants Install Solar:

1) Fear of property damage
Nigerian landlords love their houses like first-born children. So when you start drilling walls to mount panels or running new wiring, they see it as “spoiling” the house. Even if you promise to fix it later, they don’t trust you.

2) They don’t want disputes later
Imagine you pack out after two years. Who removes the panels, the wiring, the brackets? If anything looks rough, the landlord believes you have reduced the value of the house. No landlord wants argument at handover.

3) They think you are making their property look funny
Some landlords are image-conscious. Panels on the roof or wires running at the side of the building makes them feel like their house is “under experiment.” They worry about what other tenants or neighbors will say.

4) They don’t see why you should invest in their house
In their mind, if you can spend ₦1m on solar, why not just build your own house? To them, it looks like you are wasting investment on something you don’t own.

5) They prefer tenants to stick to “normal” power
For many landlords, solar still feels like luxury. They expect tenants to manage with NEPA and gen like everyone else. So when you break that pattern, they see it as you “doing too much.”

6) They suspect you’ll soon claim ownership of the house
Install solar today, tomorrow you’re repainting, next week you’re planting flowers. In their mind, you’re already practicing landlordship.

7) They fear other tenants will copy you
The moment one person brings solar, others start saying “if he can do it, why can’t I?” Suddenly the compound looks like a mini solar farm. Some landlords see that as loss of control.

They secretly believe it exposes their failure
When you put panels on their roof, it’s like you’re indirectly announcing to the world that their property can’t guarantee stable electricity. Landlords hate public shame.

9) They don’t want extra maintenance headaches
If something sparks or a panel falls during heavy wind, who do neighbors blame first? The landlord. Even if you installed it yourself, it still “his house” they’ll point at.

10) Some are just plain evil
Let’s be honest, some landlords simply don’t like seeing tenants too comfortable. If you’re enjoying cold drinks from your solar-powered freezer while NEPA is out, they feel cheated. In their mind, “tenant life” should not be sweeter than “landlord life.”

So let’s hear from you. if you’ve ever tried to install solar in a rented apartment, did your landlord support you or fight you?

In other words, I'm saying, if you spend X million setting up a solar system for yourself, how long before you spend that same amount, say if you're buying fuel every day to power a gen set.

Quick context and assumptions
We are modelling a typical 5 kW PV system for a 3-bedroom house with some night storage. For this particular scenario, deciding between a lead-acid (tubular) battery or a lithium battery doesn't make much difference, but I've added prices nonetheless. The inverter is a 5 kVA hybrid.

Fuel price for petrol generators is taken as ~₦850–₦900 per litre. Small genset fuel burn for a 5–6.5 kVA unit is estimated at 1.5–3 L/hr, depending on load; we use 2.0 L/hr as a conservative everyday average for calculations.

For a 5kW solar system, you may spend upwards of N6million. (Check image below)

So, depending on your current use of gen to power your house, your spending on fuel should look like this:

1) Light users: 2 hours/day → 4 L/day → ₦3,600/day → ≈ ₦1,314,000/year.

2) Moderate users: 4 hours/day → 8 L/day → ₦7,200/day → ≈ ₦2,628,000/year.

3) Heavy use: 8 hours (or more)/day → 16 L/day → ₦14,400(or more)/day → ≈ ₦5,256,000(or more)/year.


So, moment of truth...If you spent, say ₦5,890,000 for a 5kW solar system with the number of components as suggested in the image, it would take:
4.48 years, if you're a light generator user using 2 hours/day → 4 L/day
1.12 years if you're a heavy generator user using 16 L/day → ₦14,400(or more)/day

PS: Of course, there's a lot of simplification and assumption in this example, so please take note that real-world results will vary.

So, over to you? Is worth switching to solar?

KingMack:
I was thinking to get this to jus power my smart TV and decoder and jus a fan..any suggestions?

That's a Hithium 1KW Solar Power Station. You're perfectly safe with that amount of load.

Jakarta:
I spent around 500k switching to BAND A early last year, I average around 50k for electricity bill. A friend called it reckless spending, that solar is the way. He spent around 3m installing solar, loaded batteries on his corridor like CNG tanks on Dangote trailer. He dares not power on his refrigerator, water heater, or hot plate. As it stands his batteries and solar panels are currently for sale. I"m yet to spend 2.5M even after a year+ Nothing beats Band A.

Anybody that can afford to switch to band A should definitely do so. Nothing beats the peace of mind. In fact, i often tell my clients to do so if they're not ready to go for the kind of solar system that can conveniently carry their load. I no won dey hear, "that stupid engineer did rubbish solar for me". As for your friends case, i guess the installer never did a load audit, cos if he did, he woud have known exactly what he could power and for how long. If you're ever going solar, reach out to us at Primistine Electric. A load audit and honest evaluation is the start of any of our installations for clients.

Tailorcaesar:
I regretted buying solar controller....the sh!t no dey charge my battery 🔋....
In fact I have switched to charging my battery using normal battery charger

Hello, that's sad to hear. Can you share your setup and what you're powering? Most regrets with solar often come from a mismatch between solar system setup and load.

Primistine Electric is honestly here for you.

One of the biggest mistakes people make when going solar is skipping the math. I’ve lost count of how many stories I’ve heard of someone proudly installing their panels and batteries, only to find out a week later that the “system” can barely keep up with their load.

So, what is the secret i'm talking about this evening? Load Audit.

The truth is, load calculation isn’t some fancy engineering calculation. It’s just knowing how much power your appliances really consume and matching that with the size of your solar system. For instance, a small LED bulb might sip just 10 watts, while a standing fan takes 75–120 watts. Add a freezer (200–400 watts when running, more at startup), and suddenly your 2kVA inverter with two tubular batteries is struggling.

Without this calculation, you will fall into either of two traps. Either you overspend on a big system that you don’t fully use, or you underspend and end up with something that can’t serve you. The latter is more likely tho.

Both ways, regret is guaranteed. And here’s the kicker: even the so-called “solar installers” sometimes inflate or miscalculate loads just to sell equipment, leaving you to discover the hard way. Not us tho...reach out using the contact in the siggy.

Honestly, load calculation should be the first conversation before buying even a single panel. It saves money, frustration, and that awkward moment when you realize your solar system is only good for lighting the compound and charging phones.

So let’s be real, did you calculate your load before buying solar, or did you just buy what the installer suggested? And if you skipped it, how badly did it burn you?

If you're on a budget but still need 24/7 light, then you may have heard of these modular solar kits (the types pictured below). Plug-and-play solar kits are the tempting option right now. They arrive as a single box that claims to be a battery, inverter, and charge controller. Personally, i don't trust their claims. Haven't use one ngl, so i want say they're good or bad.


Has anyone here actually used one of those kits they parade on Jiji or Jumia? Was it your “small but mighty” lifesaver or did it end up as an expensive lantern? Kindly tell us what exact model you bought, what it actually ran, and for how long.

Don't know where to start, or have questions? Comment and i'll respond ASAP

I get a lot of questions like, "Engr., I have so, so, so amount (usually like 500k), can I get a good solar system with it?" The answer is, it depends. So, with ₦ 500,000 in your hand, what’s the smarter move: generator or solar?

Oya, let’s talk numbers. On Jumia, a Sumec Firman unit, 3–4.5 kVA, is regularly listed between ₦ 250,000 and ₦ 400,000 on various sites.
Higher capacity units, like 10 kVA generators, still hover around ₦500 000. These ones can power even fridges and pumping machines conveniently.

So, it's settled.

For around ₦500k, you could get a decent generator and still have enough left for fuel for a while.

Now, solar. This one is a bit tricky. For 500k, you can only get a system that powers your phones, laptop, lights, fans, and maybe TV.
For example, a simple setup involving a 2000W satchet inverter, one 100ah lead-acid battery, one 300W panel, charge controller, and installation can easily guzzle up your 500k. Yet, you can only power your basics.

For larger installations, like a hybrid 1.5 kVA system supporting lights, fans, TV, and others, the price jumps to ₦800 000–₦1.2 m

And a full 5 kW setup (for up to a 3-bedroom home) can hit ₦3.6 million to ₦4.5 million

So here's the reality check:

• Generator: Hands down, power, you know how many naira you're spending now. Fuel bills come later, but entry is easy.

• Solar on ₦500k: Not enough for a whole-home solution. It won’t run ACs or deep-freeze, but just enough to power your essentials till NEPA restores light.

So, if you had exactly ₦500k, would you go with a lean solar starter or get a generator?

Share your thoughts, and let's get talking. Reach out for a free consultation if you're looking to go solar.

Sometimes I wonder if we're just paying for the sins of our father's in this country. Businesses and homes are suffering under this national plague called NEPA, yet the sun shines freely every day. BUT... tapping into it feels like an exclusive privilege for those with deep pockets. Walk into most solar shops, and the first thing you hear is a six-figure quote that can easily give you a headache.

Meanwhile, the average Nigerian just wants the basics. Light for a fan when the heat is unbearable, steady power for a small freezer, maybe for TV to keep the family entertained. Nothing fancy, nothing extravagant. But somehow, even this feels out of reach because by the time you calculate panels, batteries, an inverter, and installation, the cost could build a small kiosk.

It makes me wonder: why is solar still seen as a luxury product here? I mean, in some parts of the world, i hear solar panels are so cheap that people use them as fences because it's cheaper and they can generate electricity from it (talk about killing two birds with a shot). But the same cannot be said for Nigeria? One thing i know for a fact is, the technology itself isn't that expensive. So, are middlemen and importers inflating things unnecessarily? Some people even whisper that the “solar industry” in Nigeria survives because we don’t have steady power.

The sad part is that those who try to cut corners end up regretting it. You hear stories of people spending their last savings on a kit that can barely power bulbs, then they say solar is bad, but that's just not true. And the cycle continues.

Maybe I’m overthinking, but does it really have to be this way? Shouldn’t solar be something every household can gradually scale into, instead of something only reserved for those who can comfortably write a big cheque?

So let’s talk. If you’ve tried to go solar, what shocked you the most about the cost? Was it the panels, the batteries, or the installers quote?

comment your thoughts and reach out to us for perfect installations and professional services.

Yes, you should I won't bore you with big grammar so let me break it down in plain words.

What does 'Pure Sine Wave' mean in inverter talk?
A pure sine wave inverter produces power that looks exactly like what you get from NEPA/PHCN. Smooth, clean, and steady. That’s why your appliances behave normally on it.

There are three main types of inverters:
Pure sine wave: clean like grid supply.
Modified sine wave: cheaper, but rough.
Square wave: almost useless.


Motors (like in your fridge, freezer, pumping machine, AC) run cooler and last longer on pure sine. On modified sine, they can overheat. Some devices buzz or make humming sounds if the power is not clean. Also, sensitive gadgets like smart TVs, laptops, medical devices, CCTV, routers – smething that can all be avoided with a Pure sine wave inverter.

Pure sine inverters usually have Total Harmonic Distortion (THD) below 3–5%, while the cheap ones have much higher. I’ve once adviced a client to buy a pure sine wave inverter, because i knew he had a big fridge. He went behind my back to buy modified sine inverters because of the price. Later, his fridge started making noise and the inverter itself started overheating. They ended up spending more in the long run.

When to spend extra for pure sine
1) If you run fridge, freezer, pumping machine, AC.
2) If you use smart electronics like laptops, TVs, audio, CCTV.
3) If you don’t want buzzing sound or short lifespan on your appliances.

If all you want is to power bulbs and charge phones, a modified sine inverter will work fine. But be clear about the limits.

What do you guys think? Would you pay more for pure sine or go for the cheaper modified sine if it powers your bulbs and fans?

Good day guys,

Many people who have inverters at home don’t fully understand what happens when the load is too much. I’ve had several people ask me: “If I mistakenly overload my inverter, will it spoil immediately? Or will it just trip?”

Let’s break it down in simple terms.

🔌 What Does “Overloading” Mean in Inverters?
Your inverter has a maximum capacity, usually written in KVA (kilovolt-ampere) or Watts. For example, if you buy a 1.5kVA inverter, the maximum safe load it can take is around 900–1000 watts.

Now, if you connect appliances that consume more than that limit, you are overloading it. Example:

- A 1.5HP AC (≈1200W) + Fridge (150W) on a 1.5kVA inverter = overload.
- Pressing iron (800W) + Water Pump (1000W) on 2kVA inverter = overload.

What Happens When Your Inverter is Overloaded?

- It Shuts Down Automatically (if it has overload protection)
- Most modern inverters in Nigeria (brands like Luminous, Su-Kam, Blue Gate, Felicity, Must) have built-in overload protection. The inverter will beep and shut down to protect itself.
- It Trips Breakers or Blows Fuse (if no protection): Cheaper or older models may not have proper overload protection. This means if you overload it, the fuse might blow or the inverter might trip the circuit breaker.
- It Can Get Damaged (worst case)

Batteries Suffer Too
Overloading forces the batteries to release current faster than normal. This shortens their lifespan. Instead of lasting 3–5 years, your battery may start failing in just 1–2 years.

Common Appliances and Their Average Power Ratings
see image below

How to Avoid Overloading Your Inverter
1) Know your load limit. A 1.5kVA inverter = max 1000W. A 3.5kVA inverter = max 2800W.
2) List appliances you want to power and add up their wattage.
3) Avoid high power devices like pressing irons, kettles, electric cookers, and pumps unless you have 5kVA and above.
4) Use energy-saving appliances. Inverter-friendly fridges and TVs reduce load drastically.

From My Experience
If you overload your inverter once, don’t panic. It will likely shut down and restart fine. But if you make it a habit, you will shorten the life of both the inverter and your batteries.

Over to you guys:
Have you ever overloaded your inverter before?
What happened: did it trip, shut down, or spoil?

Share your experience so others can learn.

Solar is a great investment, but let’s be honest: in Nigeria, too many people have been disappointed because their system didn’t perform as promised. Many people regret going solar because they weren't informed about certain things.

So my people, here are some things you should know before going solar:

1) Shading reduces output
Even a little shade from a tree, water tank, or neighbour’s wall can cut down the power of the whole panel string. For example, if just one cell on a panel is blocked, output can drop by 20% to 30%. This is because most panels are connected in series, and the weakest point reduces the flow for the whole chain.

Undersized Batteries
Some installers use smaller batteries to reduce cost. The system looks cheap on paper, but you’ll wake up at 2am with no light because your battery bank can’t carry you till morning.

Wrong inverter size
If the inverter is too small for your appliances, you’ll keep getting overload errors--very annoying. If it is too big also...problem, because you've just paid for capacity you're not using.

Cheap cables
Low quality wires increase voltage drop. It means you lose part of your generated power before it even reaches your battery. In the worst case, it can even start a fire. This problem alone can make you regret going solar because your battries won't charge as they should, and they can even get spoilt on time because they never get charged fully.

No proper load audit
A serious installer should first check your daily appliances and usage. Without this, your system will never be balanced to your needs. At Primistine Electric, we will never start installing without asking to know what your load looks like. This helps us advice you on what size system to choose and how to balance your load.

Skipping safety devices
Surge protection, breakers, and grounding are not “extras.” They are what protect your system and house from fire and sudden damage. Too many installers skip them to save money. Never allow anyone install for you if they can't point out the safety devics in your setup.

Bottom Line:
Solar is not just “buy panel, buy battery, connect wire.” There’s a science to it. If you don’t ask the right questions, you’ll end up with frustration instead of savings.
