Telecom Site Power

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

ComponentSpecification
Enclosure20 ft ISO container, insulated, IP55
PV array25–30 kWp, ground or roof mounted
Storage40–50 kWh LFP with BMS
DC plant−48 V rectifier bank, 600 A, N+1
Backup15 kW generator interface with auto start/stop
MonitoringSNMP + 4G gateway, alarm to NOC
Autonomy12–24 hours without solar or generator

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
