A generator feels like the cheap option. You buy it, you plug it in, you have power. But the price on the showroom floor is the smallest part of what it actually costs you — and once you add up the years, the maths tells a very different story.
For millions of Nigerian homes and businesses, the generator is the default answer to an unreliable grid. It's familiar, it's available, and the upfront price looks manageable. The problem is that a generator's real cost isn't what you pay to own it — it's what you pay to run it, month after month, for as long as you own it.
The upfront-cost illusion
When people compare a generator to a solar system, they usually compare purchase prices: the generator looks cheaper, so the conversation ends there. But that comparison ignores the single biggest line item in backup power — fuel — and the slow drip of servicing, repairs and replacement.
A generator is cheap to buy and expensive to keep. A solar-and-battery system is the opposite: more to install, then close to nothing to run. The honest comparison isn't the sticker price; it's the total cost over the life of the system.
What a generator really costs to run
Add up everything a generator quietly takes from you over a year:
- Fuel — by far the largest cost, and the one that rises with pump prices entirely outside your control.
- Servicing — oil changes, filters and routine maintenance to keep it running.
- Repairs and rewinds — the bigger bills that arrive as the unit ages.
- Replacement — most small generators have a short working life under heavy use, so the purchase cost repeats sooner than you'd think.
Run the numbers over five or ten years and fuel alone usually dwarfs the original purchase price many times over. The generator was never the cheap option — it just spread the cost out where it was harder to see.
What solar and storage cost
A solar system flips the cost curve. The upfront figure is higher because you're paying for equipment that lasts — panels, a battery and an inverter designed to work for many years. But once it's installed, sunlight is free. There's no fuel to buy, no queue at the filling station, and far less to service.
A generator is cheap to buy and expensive to run. Solar is the other way around — and over time, the other way around wins.
The catch, of course, is that upfront figure. For a lot of households and businesses, the capital cost of a good solar system is exactly the barrier that keeps them tied to the generator they already own.
The hidden costs nobody quotes
Money isn't the only price a generator charges. There's the noise, the fumes, the fire risk of storing fuel, and the simple unreliability of a machine that won't start when you need it most. There's the downtime when it fails and the fuel run when the tank is empty. None of that shows up in a price comparison, but all of it is part of what you live with.
Where Power as a Service changes the maths
This is the gap Bice Energy is built to close. With Power as a Service, you don't buy the solar system at all. We finance, install and own it — and you simply pay for the energy you use, through a smart prepaid meter, with nothing to pay upfront beyond a small application fee.
That removes the one thing keeping the generator in the picture: the capital cost. You get the running economics of solar without the upfront bill, and we maintain the system for its lifetime, so there are no repair surprises to budget for.
The takeaways
- A generator's purchase price is the smallest part of its true cost — fuel and upkeep are the real bill.
- Solar costs more upfront but close to nothing to run, so over years it usually works out cheaper.
- The upfront cost of solar is the main barrier — and it's exactly what Power as a Service removes.
- With Bice, you pay only for the energy you use, and we own and maintain the system.
The cost points above are general and illustrative, to explain how backup-power economics work. Actual costs depend on fuel prices, usage, equipment and site conditions, all of which change over time.
