Product FAQ

How much does a 20kW solar system cost in 2026?
Tier-1 modules run $0.28–0.48 per watt FOB, so a 20kW solar system starts at $5,600–9,600 in modules alone; inverters, mounting and sea freight (typically +20–35% over FOB) complete the landed figure. Send us your load profile and we will return a firm CIF quote within 24 hours.
How long does a 20kW solar system take to pay back?
Against grid tariffs, 3–5 years. Where the system displaces diesel generation at $0.30–0.60 per kWh all-in, payback falls to under 18 months — which is why factories and mills switch first.
Which certifications and import approvals apply?
Modules carry IEC 61215 with IEC 61701 salt-mist testing and inverters ship CE / IEC 62109. For imports we prepare SONCAP for Nigeria, BPS for the Philippines (mandatory from July 2027) and SASO or DEWA paperwork for the Gulf.
Can I add battery storage to this system later?
Yes. Every system in this line can be ordered as a pure grid-tied plant and upgraded later: our hybrid inverters accept LFP battery cabinets (50kWh–6MWh) without replacing the solar array. If you know storage is coming, tell us now — we will pre-wire the AC/DC distribution to make the upgrade a one-day job.
Will the system comply with my country's grid code?
The inverters carry CE and grid-compliance settings for the main export markets we serve (West Africa, Southeast Asia, the Caribbean, Latin America). For markets with mandatory conformity programs — e.g. SONCAP for Nigeria — we prepare the certification documents with the shipment. Confirm your utility's requirements with us before ordering.
20kW grid-tied or the 15kW + 50kWh battery package?
For bill savings with a stable grid, this 20kW grid-tied package wins on price per kWh. For outage-prone sites, the 15kW + 50kWh battery package trades a little array size for real autonomy. If you want both, this system's hybrid-ready inverter takes a battery cabinet whenever you are ready.

20kW solar system Price & Payback

What moves the 20kW solar system 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 factorTypical figure (2026)
Solar modules$0.28–0.48 per watt FOB, tier-1 supply
Sea freight & landed costTypically +20–35% over FOB to West Africa / Southeast Asia ports
Storage share35–50% of total system cost where batteries are included
Payback3–5 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.

For country-level landed-cost math, read the commercial solar system sizing guide, and see the 50kW bank branch project in Liberia for how the same hardware performs in the field. The IEA solar PV market track is a good neutral reference for global module price direction.
