Photonic Universe 20W Semi-Flexible Solar Panel (ETFE) | 4Boats

Durable 20W semi-flexible solar panel with anodised aluminium reinforcement and a robust ETFE surface — ideal for charging 12 V systems on boats, campervans and off-grid setups.

• Anodised aluminium reinforcement and strong ETFE coating: This reinforced semi-flexible solar panel has a unique 7-layer construction, featuring an embedded sheet of anodised aluminium fully encapsulated for exceptional strength and resilience.
• Semi-flexible design: The semi-flexible design makes it ideal for slightly curved roofs and surfaces where bonding is preferable (bolts or screws can also be used).
• Solar panel specifications: Peak power 20W; Maximum power voltage (Vmp) 17.5 V; Maximum power current (Imp) 1.14 A; Open-circuit voltage (Voc) 21.6 V; Short-circuit current (Isc) 1.21 A; Power tolerance ±5%.
• Solar panel dimensions: 450 x 350 x 4 mm (17.7 x 13.8 x 0.16 in). Junction box dimensions: 90 x 16 x 16 mm (3.54 x 0.63 x 0.63 in). Weight: 1.10 kg (2.43 lb).
• Supplied with 2 x 0.9 m (2.95 ft) solar cables; sealed, waterproof construction with high saltwater resistance and designed to withstand occasional foot traffic — suitable for marine use.
• ETFE surface: Lightly textured, anti-reflective ETFE increases light absorption, improves efficiency and offers longer service life with reduced risk of cracking, delamination and corrosion.
• Supplied with a user manual; technical drawing and handling guide (Technical Drawing of 20W Reinforced Semi-flexible Solar Panel ARFLX-20M) available to download. Fitting guidance should be read before installation.

Care & compatibility: For charging a 12 V battery this panel requires a solar charge controller/regulator and must not be connected directly to the battery. Suitable for permanent outdoor use in all weather conditions.
