Description:- 160W & 180W Solar Panels with Round Rear Junction Box

Colour:- Black backing

Contents:-  1 Panel with 3m cable

Size Options:- 

160W -  1345mm x 665mm

Other Information:- The panels with rear junction box require a cut out in the roof to enable the panel to lay flat.

This highly durable black semi-flexible solar panel is made from monocrystalline solar cells, reinforced with anodised aluminium and has a strong ETFE surface.  This model also features a rear-fitted circular junction box and 3m dual core cable.

The 160W High efficiency solar panel is perfect for permanent outdoor use to provide free electricity for charging 12V batteries to power various applications, such as in a motorhome, caravan, camper, boat, or for solar lighting systems, off-grid, and back up solar power systems. The panel can also be used to provide direct power supply for applications not sensitive to changes in input voltage / current (e.g. electric motors or pumps) and for various grid-tie applications.

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 within the solar panel. This additional reinforcement offers greater strength and resilience, making this one of the most robust semi-flexible solar panels available on the market.

In addition to the aluminium reinforcement, the surface of this 160W semi-flexible solar panel is made of strong ETFE material which has a longer service life compared to standard semi-flexible solar panels. As a result, these particular semi-flexible solar panels are extremely hard-wearing and less prone to cracking , delamination and corrosion. The lightly textured coating of this panel creates an anti-reflective surface which allows the panel to absorb a far greater amount of light, thereby increasing efficiency. 

High quality 5-busbar solar cells:

This panel also features innovative 5 busbar solar cells, which are more efficient than the 2, 3 or 4 busbar solar cells used in most other solar panels, and are able to extract more power from the same surface area. This results in a smaller overall solar panel, which is ideal for applications where space is limited. These solar cells are also the best choice for applications in warmer climates, as they operate well even in high ambient temperatures.


This particular model features the junction box and cable on the rear side of the panel to create a completely level surface and professional finish after installation. Unlike other solar panels, the junction box on this solar panel is a circular shape with only one dual core cable (3m length) attached, allowing for simplified installation.  Please note: in order for this panel to be flush-mounted, a recess must be cut in to the roof/surface.

Other benefits:

  • Semi-flexible design makes it ideal for slightly curved roofs and surfaces where bonding is preferable (though the panel can also be fixed by bolts or screws)
  • The panel is incredibly light (5.70kg)
  • High resistance to salt water environment (junction box and cables underneath are protected from contact with water) 
  • Sealed waterproof design ensures the panel can be used in all weather conditions
  • Junction box on the back allows for a smooth and level surface, free of trip hazards and unsightly cables. Round shape for easy fitting.
  • Fitted with a single length of high quality 3m dual core cable for easy installation and wiring
