Cascadia 4X4 Prinsu Roof Rack 45 Watt Modular Solar System


Cascadia 4x4 is proud to introduce the Prinsu Roof Rack Modular Solar System. This 45W Prinsu Roof Rack-specific solar panel can be run as a single unit or combined with as many units as required in order to achieve your desired power output (e.g. 4x panels produce 180W).  Each panel is mounted to a 4mm powder coated aluminum backplate that provides an abundance of different mounting options and configurations. 


  • Modular 45W solar panels: Customize your setup with as many panels as necessary for your roof rack!
  • Rugged “Marine-Grade” construction to withstand extreme environmental conditions.
  • Laser cut & powder coated aluminum back sheet provides rigidity while cutouts allow for air flow around the solar panel to aid cooling.
  • Perfect for overlanding, camping, and the jobsite. Keep your drinks cold and equipment charged without killing your battery.
  • Solar Made Simple: The optional “Plug-and-Play” complete kit includes everything you need for a clean and simple install.
  • 2 year warranty

Choose the size of your solar system by adding as many 45-watt solar panels as needed to your Prinsu roof rack. The rugged construction of the solar panels combined with the rigidity of the aluminum backplate even allows you to stack gear on top of the panels without causing any damage.

During daylight hours, the solar system provides a constant flow of clean solar energy to your primary or secondary vehicle batteries. This gives you the ability to run 12V accessories like fridges, phone/laptop chargers, lights, power inverters, etc. without the need to start your engine and without the fear of draining your battery and leaving you stranded.  

The Prinsu Roof Rack Modular Solar System should be paired with our optional MPPT solar charge controller. Our weatherproof MPPT charge controller comes pre-wired and can be conveniently mounted to the base of the solar panel(s). A single charge controller can be used for up to 2 of these 45W solar panels wired in series. A system consisting of 3 or 4 panels would require a minimum of 2 charge controllers. 

We chose the most stable and durable multilayered solar panel construction available to ensure that these solar panels can withstand extreme environmental conditions, maintenance-free, for years.


    - Keep your battery topped up at all times with a solar panel mounted on your Prinsu roof rack: Perfect for the overlander or camper who wants to power devices without worrying about draining their battery. 

    - Extend the life of your battery: The Cascadia 4x4 VSS System™ will give you longer overall battery life by tending it constantly during periods of sun exposure. 

    - Emergency engine starting device: If you ever manage to completely drain your battery the VSS System™ will start the vehicle up again in as little as 30 minutes depending on sun exposure.
