Cut Diesel at Your BTS Sites Without Touching the Grid

A single off-grid BTS site in West Africa burns 8,000–15,000 litres of diesel a year. Fuel logistics often cost more than the fuel. Theft runs 10–20%. Generator maintenance is a monthly line item.

The Problem, in Numbers

• 8,000–15,000 litres of diesel per site per year for a 2–4 kW average load
• Fuel delivery to a remote site can add 20–40% to the pump price
• Theft and pilferage run 10–20% of delivered volume on unsecured sites
• Generator servicing every 250–500 running hours, plus rebuilds at 15,000 hours
• A failed generator means a dropped cell — which means regulatory penalties

The Configuration

Smaller sites use the 10 ft variant (12–15 kWp / 20–25 kWh) or the D02 outdoor cabinet.

Payback, With the Assumptions Shown

At a typical 3 kW average load and $1.10/litre diesel, a solar-hybrid conversion displaces 60–70% of fuel. Payback typically falls in the 2.5–4 year range, depending on:

• Local irradiance (5.5 kWh/m²/day versus 4.0 changes the answer by years)
• Diesel price and delivery premium
• How much load shedding you accept on consecutive cloudy days
• Whether the existing generator is retained as backup or removed

We will run the numbers on your actual site data rather than publish a number that flatters us.

What a Deployment Looks Like

1. Week 1 — site survey: load logging for 7 days, irradiance estimate, fuel records review
2. Week 2 — sizing and proposal: configuration, bill of materials, payback model on your data
3. Week 3–6 — factory build and FAT: container wired and load-tested before shipment
4. Week 7–8 — shipment and commissioning: two engineers, five days per site
5. Ongoing — remote monitoring with quarterly performance reports
