This Process Works the Same Way for Every Facility Type
Whether you run a factory, hotel, hospital, school, residential estate, or warehouse — the qualification, design, and installation process is identical. Only the system sizing and engineering approach changes.
Solar for Factories
100kw–5MW systems for manufacturing plants.
Solar for Hotels
24-hour hybrid systems for hospitality.
Solar for Hospitals
Uninterrupted power for critical facilities.
Solar for Schools
Lower overheads for campuses and boarding schools.
Solar for Developers
Estate-wide solar for residential developments.
Solar for Warehouses
Cold-chain and logistics facility power.
Two Parties. One Direct Process.
No middlemen, no third-party installer handoff. You work with Olasupo Energy from your first message through to a commissioned system.
You — The Business
The factory, hotel, hospital, school, estate, or warehouse that needs commercial solar and wants a fair price with no surprises.
Olasupo Energy — Your Installer
That's usWe design, install, and support your commercial solar system ourselves, in-house, from your first message through years of after-sales service.

You Contact Us on WhatsApp
Every commercial solar enquiry — factory, hotel, hospital, school, estate, or warehouse — starts with a single WhatsApp message to our team directly. You tell us what type of facility you have and roughly what your diesel situation looks like. That is all we need to begin.
No forms, no registration, no waiting for a callback. Our WhatsApp is monitored Monday to Saturday 8am–6pm and we respond within 5 minutes during business hours.
What to include in your first message
We Qualify Your Requirements in 15 Minutes
We ask you five specific questions on WhatsApp. Not to gatekeep — but because the answers are what our engineering team uses to size your system correctly and prepare for your site visit before we ever set foot on your property.
This conversation takes 10–15 minutes and happens entirely on WhatsApp at your pace. No phone calls required unless you prefer one.

Our Engineers Visit for a Free Site Assessment
Within 24–48 hours of qualification, our own site engineers — not a third party — schedule a visit to your facility. They assess the rooftop, measure the electrical load, review your generator setup, and take everything they need to design your system correctly the first time.
This is completely free and comes with no obligation to proceed. Because our design and installation teams work under one roof, nothing gets lost in translation between an assessment and the system that eventually gets built.
What our site visit covers
Rooftop structural inspection and available installation area measurement
Electrical load assessment across all generators and mains
Grid connection evaluation and inverter placement planning
Shadow analysis and panel orientation optimization
Battery storage sizing based on overnight load requirements
Full system design and itemized cost proposal within 5–7 days
Our Design Team Builds Your System and Proposal
Using the data from your site visit, our in-house engineering team designs a system sized to your actual load — not a generic package. You receive a full proposal with panel and battery specifications, inverter sizing, an itemized cost breakdown, and a projected payback period.
Because we design and install the system ourselves, there is no separate installer marking up our own quote. The price you see in the proposal is the price you pay.
Why our designs hold up on site


Review the Proposal, Ask Questions, Sign When Ready
We walk you through the proposal line by line before you sign anything — system sizing, component specifications, warranty terms, and payment milestones. Every line is explained, not just handed over.
Take as long as you need. If your requirements change after the site visit, we revise the design and re-quote at no extra cost. There is no pressure to sign on the spot.
What's included in every proposal
We Install, Commission, and Stay On for Support
Once you sign, our own crews handle the entire installation — procurement, rooftop work, electrical connection, battery installation, inverter setup, and commissioning. You continue operating normally throughout, and you deal with the same team that assessed and designed your system.
Because there is no separate installer in the loop, there is no handoff where things get missed. One team is accountable for the system from the first WhatsApp message to years of after-sales support.

Questions About the Commercial Solar Process
Is the qualification call and site assessment really free?
Yes — the qualification call and the site assessment cost nothing and carry no obligation. You only pay once you review and sign the installation proposal, and even then payment follows the milestone schedule set out in your contract, not a lump sum upfront.
Do you subcontract installation to a third-party company?
No. Olasupo Energy handles qualification, site assessment, system design, procurement, installation, and commissioning with our own team. You are not handed off to a separate EPC company partway through the process.
What if I do not like the proposal you send me?
You are under no obligation to proceed. If the initial design does not meet your requirements, we revise the system and re-quote at no extra cost until it does — or you can walk away with no charge for the assessment or design.
How do I know your team can handle a project the size of mine?
Our engineering team is licensed and has completed multiple commercial installations above 100kw with verifiable client references. During the proposal stage we're happy to share relevant project history for facilities similar to yours.
What happens after the solar system is installed?
Your installation contract includes a workmanship warranty from us on top of manufacturer warranties on the components. We remain your point of contact for maintenance, monitoring, and any future capacity expansion — you don't need to find a separate provider.
How long does the whole process take from first message to installation complete?
From first WhatsApp message to a signed contract is typically 3 weeks. Installation then takes 4–12 weeks depending on system size — a 100kw system installs in 3–4 weeks, a 500kw system takes 8–12 weeks. Total from first contact to an operating solar system is typically 7–15 weeks.
Does this process work the same for hotels, hospitals, schools, and estates — not just factories?
Yes. The qualification, site assessment, design, and installation process is identical across every facility type we serve. Only the system sizing, battery configuration, and engineering approach differ based on your specific load profile.
We Install for Businesses in Every Major Nigerian City
Every site visit and installation is handled by our own crews, who know the local grid conditions, council requirements, and logistics in your area.
