Technical Specifications & Performance

1. Output Power: 400 Watts
2. Cell Technology: Monocrystalline PERC, which offers better performance in low-light (overcast) conditions.
3. Voltage at Pmax (Vmp): ~41.0V – 42.0V
4. Current at Pmax (Imp): ~9.5A – 9.8A
5. Dimensions: Approx. 2008 x 1002 x 35 mm
6. Durability: Features tempered glass and a reinforced aluminum frame designed to withstand 10+ years of harsh outdoor exposure.

The 400W Efficiency Edge

1. Lower Installation Costs: Because you get more power from a single panel, you need fewer mounting rails and less wiring compared to using smaller 100W or 200W panels.
2. Modern Inverter Support: Most 2026 hybrid inverters (Deye, Felicity, Growatt) are optimized for the higher voltage and amperage outputs of 400W+ panels.
3. Space Savings: Ideal for urban Lagos or Abuja homes where roof space is limited but power demand is high.

Important Connectivity Note

Since 400W panels are high-voltage, they require an MPPT to function efficiently.

1. For a 24V System: You can connect two 400W panels in parallel.
2. For a 48V System: Connecting panels in series allows for faster charging and uses thinner, more cost-effective cables.
3. for an 800W System: combine 2 400W panels

Conclusion: Professional Grade Power

The 400W Solar Panel is a heavy-duty solution for those who want a "set and forget" power system. It is robust enough to handle the core power needs of a modern Nigerian home.
