Your Solar System Is Failing Because of this Simple Sizing Mistake
The Hidden Reason Your Solar System Keeps Failing
You’ve invested in solar — the panels are shining on your roof, the batteries are new, and the inverter hums quietly. Yet, a few months later, things begin to fall apart:
- The batteries stop charging fully.
- The inverter keeps tripping.
- Your lights flicker at night.
Sound familiar?
Here’s the hard truth: it’s not about poor product quality — it’s about poor sizing.
Yes. One simple sizing mistake is the reason most solar systems in Nigeria and across Africa underperform or fail completely. And guess what? Many installers won’t tell you this, because the less you know, the easier it is for them to oversell or undersize your system.
But today, that ends. Let’s uncover the truth — and show you how to fix it once and for all.
The Silent Killer: Wrong Load Calculation
Every solar setup starts with one thing — your energy load. That’s the total amount of power your appliances consume daily.
Get this wrong, and everything else (panels, batteries, inverter, charge controller) collapses like a house built on sand.
Most people (and even some installers) guess their load size.
They’ll say things like, “Two panels and one battery will be fine for you.”
But will it?
Let’s do the math.
How to Get It Right — The Correct Load Calculation Formula
Here’s the formula every solar user must know:
Total Load (Wh) = Power (W) × Time (hours used per day)
Then sum up all your appliances.
For example:
| Appliance | Power (W) | Hours Used | Energy (Wh) |
|---|---|---|---|
| TV | 100 | 5 | 500 |
| Fan | 70 | 10 | 700 |
| Laptop | 60 | 6 | 360 |
| Bulbs (x5) | 15 | 8 | 600 |
| Total | 2,160 Wh |
So, your system must comfortably supply at least 2,160 Wh per day — preferably with a 20% safety margin.
Now, here’s where people go wrong — they buy a 1kVA inverter or two small panels, thinking it will work. But without proper solar sizing, they’ll be disappointed.

Why Wrong Sizing Destroys Your Investment
When your solar system is undersized:
- Batteries get drained too often, shortening their lifespan.
- Panels don’t charge fully.
- Inverters overload and shut down.
- The system becomes unreliable — especially at night or during cloudy weather.
In short, you waste money, time, and trust in solar technology.
That’s why proper solar system design is non-negotiable.

Final Thoughts — Get It Right, Get It Once
Most solar systems don’t fail because the components are bad — they fail because the design was wrong from the start.
Before you add another panel or buy a new battery, pause and run a proper solar sizing check. You’ll be shocked how much difference it makes.
Don’t let one simple mistake ruin your solar experience.
