180W ETFE Flexi Solar Panel Roof and Deck Top Kit - Rear Exit

The 180W ETFE flexi panel roof and deck top kit provides all you need to install the panel on the roof of a vehicle or the deck top of a boat. With a robust ETFE surface on both the top and bottom for resilience and longevity, the panel's efficient solar generation delivers up to 750W a day to ensure the leisure battery is charged and ready for use. Benefitting from a two year product warranty, the fitting kit is supplied with a 0.9m cable (attached), 3m cable, diode box, fuse and fuse holder, 20A charge controller, bonding agent and detailed installation instructions. ...

Product information


Product support

Find fitting instructions, advice on expanding a solar system and answers to frequently asked questions on our dedicated support page for PV Logic Flexi Solar Panels.

The benefits of ETFE

Featuring a tough, double-sided, laminated outer layer, the 180W Flexi ETFE solar panel is designed and built for durability. High weather and corrosion resistant, the panel is IP67 rated and tested to ASTM B117 - ISO9227. That’s proven exposure to saltwater spray for more than 1000 hours as well as accelerated Ultraviolet (UV) testing to ISO 4892.

The dimpled surface pattern in our ETFE Flexi panels deliver excellent light transmission to the high efficiency monocrystalline solar cells maximising solar power generation.

The panels are suitable for flat and slightly curved surfaces and perfect for campervans and leisure vehicle roofs where panel weight needs to be minimised.

Completely waterproof

Each panel is assembled to ensure complete encapsulation. This ensures the six layer heavy duty laminate protects the solar cell circuit from extreme conditions. The junction box is also injected with special silicon, guaranteeing no water ingress.

Superior design

There are no square edges on a PV Logic flexi solar panel! Rounded panel corners and a unique curved junction box provide superior adhesion, no snag lamination and no sharp edges. The junction box is mechanically fixed in addition to being bonded to the panel. Strain relief is provided for the fitted 0.9m UV stabilised PV cable ensuring it cannot be accidentally pulled from the junction box. 

Easy fix

The flexi range can be bonded to flat or slight curved surfaces (3cm curve per metre) such as painted aluminium, metal, GRP and fibreglass using Teroson MS939

Installation method

Please only use the glue pattern below for land based vehicles (this is covered in more detail in the instructions), which ensures air flow under the panel is achieved preventing heat build-up and potential warping under extreme heat.

Taking control

The 180W ETFE flexi kit includes a 20A PWM charge controller. There is an option to upgrade to the 15A MPPT Pro charge controller.  Both are capable of charging 12V and 24V batteries.

The MPPT Pro charge controller increases solar yield by up to 20% over a standard charge controller by artificially modifying the voltage from s solar panel system to actively match any battery's requirements. This means that whatever the weather conditions your panels will deliver maximum power with minimum electrical loss.

The MPPT charge controller comes with its very own free-to-download Bluetooth app (Apple and Android) to display how the solar system is performing.

Please note 

All of our semi flexible panels will only bend from the top (has the cable and logos) to the bottom a maximum of 10% of panel length.
Bending the panel greater than this, or trying to bend the panel from left to right will possibly damage the panel and also invalidate your warranty.
