Black 120W semi-flexible mono-crystalline solar panel with a rear mounted junction box, ideal for discreet and aesthetically pleasing installation on dark coloured roofs, vehicles or mounting surfaces.
120w Black Reinforced Semi-Flexible Solar Panel ETFE – Rear Junction Box
120w Black Narrow Reinforced Semi-Flexible Solar Panel with ETFE Coating and Rear Junction Box
The way flexible solar panels are often bonded to vehicles, you don’t want to to be buying cheap ones that you will need replacing in a few years. This highly durable semi-flexible solar panel reinforced with anodised aluminium and a strong ETFE surface and made from German mono-crystalline solar cells is a good choice that will offer you years of use.
This model has a rear counted junction box with 3m of cable so this panel can be completely flush mounted to a surface.
This high efficiency 120W 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 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 , de-lamination 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. ETFE material has long been used in applications where durability and high-temperature resistance is required, such as in the Eden Project, Cornwall. You can read more about ETFE and its benefits on our blog.
High quality German solar cells:
The high-efficiency mono-crystalline German solar cells used in this solar panel have excellent performance in low light conditions (particularly when compared to solar cells of unknown origin) and they produce a good amount of power even in daylight – when direct sunlight is not available. These long-lasting German solar cells will provide many years of consistent, free power.
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.
Back Mounted Junction Box
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.
This solar panel has a unique black backing, making this solar panel ideal for discreet and aesthetically pleasing installation on dark coloured roofs, vehicles or mounting surfaces. Please note that this solar panel is not ‘ultra jet-black’ – the exact hue may vary marginally from panel to panel, depending on the batch of solar cells.
- 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 (only 4.3kg) which is great for all vehicles
- High resistance to salt water environments and possibility to walk on the panel make it perfect for boats and yachts.
- Sealed waterproof design ensures the panel can be used in all weather conditions.
