120W Solar Panel FLAXBJB-120M

Premium Black Semi-Flexible Fibreglass ETFE

The FLAXBJB-120M is a high-performance 120W monocrystalline solar panel engineered for demanding environments. Featuring a unique rear-mounted junction box, this panel provides a completely flush surface once installed, making it the perfect choice for aesthetically pleasing installations on vehicle roofs or boat decks where trip hazards and visible cabling must be minimized.

ADVANCED ETFE COATING: The textured ETFE surface is highly durable, offering superior resistance to salt water, UV degradation, and extreme temperatures compared to standard PET panels.

Constructed with glass-fibre reinforced plastic, this panel is incredibly thin (2mm) and lightweight (2.14kg), allowing it to conform to curved surfaces with an arch height of up to 122mm. The 5-busbar solar cells ensure maximum efficiency even in low-light or cloudy conditions.

Key Features

  • Rear Junction Box: Low profile, professional finish.
  • ETFE Surface: Robust, non-stick, and self-cleaning properties.
  • Marine Grade: Highly resistant to salt water environments.
  • Lightweight: Only 2.14kg - ideal for structural weight limits.
  • High Efficiency: 5-busbar monocrystalline cells.

Installation Guide

1. Surface Preparation: Ensure the mounting surface is clean, dry, and free of grease. Bonding with a high-quality marine-grade adhesive (e.g., Sikaflex) is recommended.

2. Junction Box: As this model features a rear-mounted junction box, a small hole must be cut into the mounting surface to accommodate the 30mm diameter box for a flush finish.

3. Wiring: Connect the 3m dual-core cable to a suitable 10A (or higher) Solar Charge Controller. Do not connect the panel directly to a battery.

Questions & Answers

What are the benefits of the ETFE coating?

ETFE (Ethylene Tetrafluoroethylene) is a high-strength fluorine-based plastic. It is more durable than standard PET, offers better light transparency, and has a textured surface that reduces reflection, increasing efficiency in cloudy conditions.

Can I walk on this solar panel?

Yes, when properly bonded to a solid, flat surface (such as a boat deck), this reinforced fibreglass panel is strong enough to be walked on in soft-soled shoes.

How much can this panel bend?

This panel is designed for slight curvatures. The maximum recommended arch height for the 1000mm length is approximately 122mm. Over-bending may damage the internal solar cells.

Note: Please verify measurements and technical requirements before purchasing. Professional installation recommended for drilling/cutting surfaces at solarika.co.uk.
