What the Estimate Is Actually Based On
A lot of online solar calculators run on a fixed global formula that ignores local fuel prices, grid tariffs, and sun hours — which produces a payback number that doesn't hold up once a real quote comes in.
Ours is built around what actually drives your number: your current spend, your property type, and typical system costs for Nigerian sites. It's a starting estimate, not a final quote — the exact figure comes from a free site assessment that checks your load, roof or land, and access.

From Estimate to an Exact, In-House Build
The calculator gives you a starting point. What happens after is the part that determines whether the real payback matches the estimate — and that's handled entirely by our own team, from assessment through to commissioning.
Free site assessment follows every estimate
We turn your calculator result into an exact quote by checking your actual load, roof or land, and access — at no cost.
In-house engineering & design
The same team that reviews your estimate designs the system, so nothing is lost in a handoff between departments.
Sourced direct from manufacturers
We buy panels, inverters, and batteries direct from tier-1 manufacturers, keeping actual project costs close to the estimate.
Own crews install and commission
Our certified technicians carry out installation and commissioning, so the completed system performs the way it was modeled to.

ROI Calculator Questions — Answered
How accurate is the ROI calculator?
It's built on Nigerian fuel prices, grid tariffs, and typical system costs, so it's a solid starting estimate — but it doesn't account for your specific roof, land, or equipment, which is why we follow up with a free site assessment for an exact figure.
Do I need to give my contact details to use the calculator?
No. The calculator gives you an instant estimate on its own. You only share your details if you want us to follow up with a free site assessment.
Why does the calculator's estimate differ from my final quote?
The calculator uses your spend and property type, while the final quote also factors in your actual load, roof or land condition, and site access — all confirmed during a free in-person assessment.
What information do I need before I start?
Just a rough idea of your monthly diesel or grid spend and your property type. If you're not sure of the exact figure, an estimate is fine — the site assessment will confirm the real numbers.
Is the site assessment really free?
Yes. Once you send us your calculator result, we schedule a free site assessment to confirm your load, check your roof or land, and turn the estimate into an exact, buildable quote.
Free Site Assessments Across Nigeria
Once you've run the calculator, we follow up with a free site assessment wherever you're based — Lagos, Abuja, Port Harcourt, Kano, Ibadan, Ogun, and beyond.
