You don't have to choose between solar and your generator
A lot of hesitation around solar comes from an assumption that it's all-or-nothing — that going solar means getting rid of the generator entirely and hoping for the best. In practice, the most common and most sensible path is a phased handover: solar and battery take over daily, predictable loads, while the generator stays on standby for rare, exceptional demand. Fuel spend drops sharply from month one, without removing your safety net.
Stage 1: Identify what's actually running your fuel bill
Before sizing anything, it helps to know which loads are driving daily generator use. For most households, it's a short list:
- Lighting and fans, running for hours every evening
- A fridge or freezer, running continuously
- A TV, router and phone charging
- Occasionally, a fan-cooled or split AC unit
A proper energy assessment quantifies this precisely, but even a rough version — the same appliance-and-hours exercise from our battery sizing guide — usually reveals that 80–90% of daily generator hours are covering a fairly modest, predictable load.
Stage 2: Size solar and battery to cover that predictable load
This is where a system like our Home Plus package (5kVA inverter, 10.24kWh battery, 5kW solar array) earns its keep — sized specifically to carry the loads identified in Stage 1 through a normal day and evening, recharging fully the next day. Once installed, the generator simply isn't needed for that routine load anymore.
Stage 3: Let the generator become the exception, not the rule
With solar and battery covering daily use, the generator's job changes: it's there for the days solar genuinely can't keep up — an unusually long stretch of heavy cloud cover, an appliance-heavy event, or simply while a family gets comfortable trusting the new system. Many of our customers report going from daily generator use to running it a handful of times a month, sometimes less.
What this actually saves, in practice
Using the numbers from our solar vs. generator comparison, a household running a generator 8 hours a day can spend ₦150,000–₦180,000 a month on fuel alone. Shifting that daily load onto solar and battery — while keeping the generator for occasional use — can cut that monthly figure by the large majority, since the generator only runs a few times rather than daily.
Common concerns, addressed honestly
"What if solar just isn't enough some days?"
This is exactly why keeping the generator during the transition — rather than selling it immediately — is the sensible approach. Most households naturally reach for it less over time as they see how consistently the solar system performs.
"Is it worth doing this in stages, or should I go all-in at once?"
Both are valid. Some customers install a full system matched to their eventual target from day one; others start with an Essential package and expand battery or solar capacity later as budget allows. Financing through Rivy makes the full-system route more accessible upfront if that's your preference.
"Will my family actually notice a difference day-to-day?"
Almost always, yes — the most commonly reported change isn't the fuel savings, it's the quiet. No generator noise through the evening, no fumes near the compound, and no late-night refill runs.
The realistic timeline
| Stage | What happens | Typical outcome |
|---|---|---|
| Week 1 | Energy assessment and system sizing | Clear picture of actual daily load |
| Weeks 2–3 | Installation and commissioning | System live, covering daily use |
| Month 1–3 | Generator use drops sharply | Fuel spend falls; generator used occasionally |
| Ongoing | Generator becomes rare backup | Most households report near-zero routine generator use |
FAQs
Should I sell my generator once solar is installed?
We generally don't recommend it, at least initially. Keeping it as a backup-to-the-backup costs nothing beyond occasional fuel and gives peace of mind while you build trust in the new system.
How quickly will I see the fuel savings?
Immediately for the loads the new system covers — most customers notice the change in their very first fuel purchase after installation.
Can Lumion Energy help me phase this in over time?
Yes — our energy assessment is designed to map out both an immediate system and a sensible expansion path, so you're not locked into guessing what you'll need in two years.
