Unlike traditional monofacial panels, the SWB-400M utilizes advanced dual-sided solar cells to capture sunlight on both the front and rear surfaces, harnessing reflected light from the ground to increase energy output by up to 20%. RELIABILITY: Built with innovative multi-busbar technology and a reinforced anti-corrosive aluminum frame to withstand harsh environmental conditions while maintaining peak performance. Key Features ✔ Bifacial Gain: Up to 20% extra yield from rear-side light ✔ All-Weather Design: IP68 rated junction box ✔ Pre-Wired: 60cm cable with MC4 connectors ✔ Space Efficient: High power density for limited roof space Technical Specs Peak Power (Pmax) 400W Max Power Voltage (Vmp) 30.98V Max Power Current (Imp) 12.91A Open Circuit Voltage (Voc) 37.10V Short Circuit Current (Isc) 13.80A Dimensions 1722 x 1134 x 30 mm Weight 21.0 kg Compatibility & Fitment Guide Application Requirement Notes 12V Battery Charging MPPT Controller (30A+) Ideal for motorhomes/caravans 24V Battery Charging MPPT Controller (20A+) Efficient off-grid storage Mounting Systems Standard 30mm Profile Compatible with Z-brackets & rails OEM Cross Reference Manufacturer Part Number / Reference Photonic Universe SWB-400M Industry Equivalent 400W Bifacial Mono 108-Cell Installation Guide The SWB-400M is designed for plug-and-play integration via its pre-installed 60cm solar cables and MC4 connectors. For bifacial gain, it is recommended to mount the panel at least 0.5m above a light-coloured or reflective surface (such as white gravel or light roofing). Always use a high-quality MPPT charge controller to manage the high current output of this panel. Questions & Answers Is this a genuine Solarika part? Yes, this is a premium Solarika branded panel manufactured to the specific technical standards of the SWB-400M design for long-term off-grid performance. How do I know if it is compatible with my controller? Check the "Max Power Current" (12.91A). Ensure your MPPT charge controller is rated for at least 30A for a 12V system or 20A for a 24V system to handle the full output. What is the benefit of bifacial technology on a flat roof? Even with limited ground clearance, bifacial panels capture diffuse light and reflections, typically resulting in a 5-10% increase in yield compared to standard panels on flat surfaces. Note: Solarika.co.uk recommends verifying your mounting area dimensions and charge controller capacity before purchase.
