What moves the 125kW BESS price? Module pricing first: tier-1 modules currently run $0.28–0.48 per watt FOB. Inverter class, mounting type and cable runs come next, and where batteries are included, storage typically adds 35–50% of the total system cost. Sea freight and clearing usually add 20–35% over FOB to reach West African or Southeast Asian ports.
| Cost factor | Typical figure (2026) |
|---|---|
| Solar modules | $0.28–0.48 per watt FOB, tier-1 supply |
| Sea freight & landed cost | Typically +20–35% over FOB to West Africa / Southeast Asia ports |
| Storage share | 35–50% of total system cost where batteries are included |
| Payback | 3–5 years against grid power; under 18 months when replacing diesel |
For a verified reference point: our most-ordered 100kW solar system paired with a 215kWh BESS cabinet quotes CIF $88,000–115,000 to ports such as Lagos or Manila. Every Mars Solar quote is factory-direct: FOB from our Foshan plant or CIF to your port, with the full certification dossier included.
