Why 400W Solar Panels?
- Optimal size-to-power ratio for most residential roofs
- Higher efficiency means fewer panels for the same system size
- Lower balance-of-system costs – fewer rails, fewer connections
- Available in monocrystalline, bifacial, and all-black options
- 25-year product and performance warranties standard
400W panels are ideal for maximizing energy production on limited roof space. Their higher wattage per module reduces the total panel count needed, lowering racking and labor costs. Most 400W modules feature half-cut cell technology for better shade performance and lower temperature coefficients.
PES Supply stocks 400W panels from multiple brands so you can compare specifications, warranties, and pricing. Whether you're installing a 5kW residential system or a 500kW commercial array, our team helps you find the right panels at the right price.
