SWB-400M 400W Bifacial Solar Panel
Ultra-High Efficiency Bifacial Monocrystalline Technology
The Solarika SWB-400M is a high-performance 400W bifacial monocrystalline solar panel engineered for maximum energy harvest. 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%.
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

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.
