SolarKiosk — Solar Phone Charging Solutions for Emerging Markets

The Reality

This Is Why We Exist

Across Sub-Saharan Africa, phone charging is a daily struggle — not because phones are scarce, but because reliable power is.

Nigeria national power grid collapse news

The grid keeps collapsing

National grid failures make headlines again and again. In many areas the power is out more often than it is on — a wall socket is never a promise.

Charging today is unsafe chaos

Makeshift boards, overloaded adapters and tangled cables. People leave phones for hours with strangers, with no metering, no security and no protection for their data.

We Were Born to Change This

FLOWVISUAL SolarKiosk delivers secure, metered, solar-powered charging stations — each port individually controlled, each payment recorded, powered entirely by the African sun. No grid. No fuel. No chaos.

Product Line

Four Charging Solutions, One Platform

Matched to local purchasing power and operating scenarios — from a one-person street cart to an indoor wall-mounted charger. All stations connect to the same cloud management platform.

Manned · Mobile

Portable Solar Charging Cart

Wheeled 0.8mm powder-coated steel cart with folding solar canopy. 16 USB fast-charge ports (5V/3A, 9V/3A, 12V/2.5A), 150W mono panels ×2, 12V 120Ah lithium battery, 1200W inverter with AC/gas generator backup, GPS tracker.

IC card charging station embedded in a wall

Self-service · Smart

IC Card Smart Station

Unmanned 16-port cabinet with IC card top-up and per-port control. Android terminal + RS485 port control board, real-time current metering and cloud billing — our proven core system.

Mobile money charging station in an African market

MoMo · Unmanned

Mobile Money Station

Same hardware, payment switched to Flutterwave mobile money (M-Pesa, MTN, Airtel). Users scan, pay in local currency, port unlocks — ideal where bank cards are rare but phones are everywhere.

Indoor · AC Power

Indoor AC Charging Station

For shops, kiosks and public spaces with grid power: compact AC-powered charging counters with the same card/MoMo payment core. Rentable to shop owners as a value-added service.

Technology

Smart System — Explained in Plain Language

No engineering degree needed. Here is exactly how a SolarKiosk station works, from the moment a customer pays to the moment you see the money in your dashboard.

SolarKiosk smart charging cabinet with touchscreen

Customer pays — by card, phone or cash

The customer taps an IC card or scans a QR code with M-Pesa / MTN MoMo / Airtel Money. The touchscreen confirms in 2 seconds. No smartphone? The site operator can accept cash and start the port for them.

The "brain" (Android terminal) unlocks one port

A small Android computer inside the cabinet sends a command over an industrial cable (RS485) to the control board — like a light switch, but one switch per charging port. Only the paid port turns on.

Every port counts its own electricity

The control board measures current, voltage and temperature on each port in real time. When charging finishes (or time runs out), the port switches off automatically — no waste, no arguments.

You watch it all from your phone

Each transaction travels via 4G to the cloud dashboard: which port, how long, how much money. If a cable is cut or a door is forced open, you get an alarm instantly.

👤 Super Admin — owns the whole business→ 🏢 Country Agent — runs one country's sites & revenue share→ 🧑‍🔧 Site Staff — sees only their own stations

Three-level account management: every person logs in and sees exactly what they should — no more, no less. Money flows up, reports flow down.

Payment received→ Cloud records & splits revenue→ Station unlocks port→ Metered charging→ Auto stop + report

Beyond Charging

Multiple Business in a Box

One prefabricated solar kiosk = a complete small-business platform. The operator owns the box and rents it out; entrepreneurs step in and start earning the same day.

Born from our sheet-metal fabrication and FRP kiosk production lines, the SK07B modular branded solar kiosk turns one 1950×2650×2400mm galvanized steel box into a whole micro-economy — phone charging, telecom services, mobile money, retail, even a barber or tailor shop. For many African communities where monthly income is under $100, this is the lowest-cost storefront possible — and a real job for unemployed youth and persons with disabilities.

Rent-a-shop model: investor buys & imports the kiosk (~$1,000 landed incl. shipping), secures the local license, and collects rent from small business owners — tailor, phone repair, barber, hair dresser, BBQ stall
Ready-to-work interiors: working table, mirror, cloth shelves, accessory cabinet, stainless BBQ shelf & grill — configured per trade
Telecom & fintech services: airtime & SIM sales, phone charging, mobile money & agent banking, e-government registration — one kiosk, multiple daily income streams
Solar powered from day one: 30W–200W panel options with gel/lithium storage, LED lighting, DC fan and 2–8 USB charging ports — no grid needed
Built to last & move: 0.8mm powder-coated sheet metal on galvanized tube frame, 5–8 year lifespan, recyclable, flat-packable and relocatable

The Full Stack

Kiosk + Starlink + Super WiFi + Solar = Rural Communication Base Station

The same kiosk upgrades into a small-scale telecom hub — internet where the mobile network doesn't reach.

🛰️ Starlink backhaul+ 📶 Super WiFi router+ 🏪 Business kiosk+ ☀️ Solar power

🛰️

Starlink Uplink

Satellite broadband reaches villages no fiber or tower ever will — mounted right on the kiosk roof.

📶

Lens-Antenna Super WiFi

Meta-material Luneburg lens router: signal dozens of times stronger than standard antennas, indoor 500–3,000㎡ / outdoor up to 100,000㎡ coverage, mesh multi-hop networking.

👥

Whole Village Online

256 concurrent users, 150 streaming video at once, 1800Mbps. 15W power draw — trivial for the solar system.

💰

Sell Connectivity

WiFi vouchers, charging, airtime and retail from one site — connectivity becomes your highest-margin product.

Validated by the field — we just deploy it smarter

Our concept is proven by Rural Digital Center projects already running in Nigeria (Hotspot Network × MTN): rural Nigeria is 50% unconnected to the digital ecosystem, only 23% of rural households have electricity, and 37% are unbanked. Those projects prove enormous demand — but they rely on 40-foot container centers and traditional solar mini-grid construction: heavy, slow, permanent.

We go small and beautiful: a human-scaled kiosk on a street corner instead of an industrial power station — communities actually welcome it
We go mobile: relocatable wherever foot traffic moves, no civil works, deployed in days not months
We go consumer-grade: like China's shared power-bank model — except in Africa the phone charges on the spot: pay, plug, wait a few minutes, take your fully charged phone home. No deposit, no return trip

Business Value

A Charging Station Pays for Itself

Over 600 million people in Sub-Saharan Africa lack reliable electricity. Phone charging is a daily, cash-backed, non-discretionary expense — and solar removes the fuel cost entirely.

$1–2

Daily revenue per station

16 ports × $0.1–0.15 per charge, 3–5 cycles/day in busy markets.

6–14 mo

Typical payback period

Depends on traffic and pricing; field data from Nigeria & Kenya deployments.

3 levels

Franchise-ready management

You run the country, agents run cities, platform handles billing — revenue split automated.

0 fuel

Solar-only operation

No generator fuel, no grid bill. Generator input only as backup.

Multi-stream

Kiosk upsell potential

Charging + retail + printing + SIM/airtime sales multiply income per site.

ESG

Impact & carbon story

Every station displaces small gasoline generators — fundable via green programs.

Projects

Scenario-Based Delivery

We customize by country economy level and site scenario — one product family, many configurations.

Business in a Box kiosk deployed in an African town square

Town Square · Business in a Box (Manned)
