This bank branch in Monrovia depended on diesel generators for 60% of its operating hours. Liberia's grid delivers power only intermittently, and a bank cannot tolerate downtime — ATMs, security systems, and transaction servers must run 24/7. Monthly diesel and grid costs totaled $2,800.
The branch required zero-interruption power for banking operations. Diesel generators were noisy, required constant maintenance, and fuel price volatility made budgeting impossible. The bank needed a silent, reliable, and cost-predictable alternative.
Mars Solar designed a hybrid solar power system with battery storage sized to carry the full branch load through nights and grid outages. The LFP battery bank provides 8+ hours of autonomy at average load, with seamless switchover in milliseconds.
| Solar PV Capacity | 50 kW (Tier-1 mono PERC modules) |
|---|---|
| Battery Energy Storage | 150 kWh LFP, 6,000-cycle rated |
| Inverters | Hybrid inverter, 3-phase 50kW |
| System Type | Hybrid: grid + solar + battery |
| Autonomy | 8+ hours at average load |
| Installation | 4 days, Mars Solar certified team |
The solar power system now covers 85% of the branch's annual energy needs. Monthly energy costs fell from $2,800 to under $500. The generators now run only during scheduled maintenance tests. Noise complaints from neighboring offices stopped entirely.
| Monthly savings | $2,300 |
|---|---|
| Annual savings | $27,600 |
| Payback period | 13 months |
| Energy cost reduction | 82% |
| Grid independence | 85% of annual demand |
“Our branch has not experienced a single minute of downtime since installation. The ROI was confirmed within 13 months by our own accounting.”

Branch banking cannot go dark: ATMs, teller terminals and network equipment need continuous power, and outages are routine across much of West Africa. A solar system for bank branches is sized against the full branch load rather than lighting alone, with several hours of battery autonomy built in. Our 40–125kVA BESS line is the standard building block for a solar system for bank rollouts, so the same design can be repeated across dozens of branches. If you are costing a solar system for bank, send us your load profile and your latest electricity or fuel bills — we return a sized design, a landed quote and a payback model within 24 hours.
