This is the best solar panel currently on the market to fit flush mounted inside our Sprinter Stealth+ Roof Rack side to side (replacing the discontinued Renogy 175w panel) for maximizing space to wattage output. For our Promaster Rack and Transit Rack we recommend the Rich 250w solar panel to maximize output for the width. 

Newpowa's 180W Monocrystalline 12v Solar Panel is commonly paired with van, RV, marine, camping, and various off-grid applications. Use our Flush Solar Panel Brackets for the best fit and aerodynamics if installed on our Transit or Sprinter rack.


  • Under ideal conditions, 9 busbar PV module will outperform the dated 5 and 6 busbar technology. The void space reduction between the 9BB solar cells is designed to enhance the overall efficiency of the PV module by lowering current lengths and mitigating against loss of output.

  • What’s the difference between monocrystalline and polycrystalline panels?

    Polycrystalline panels, which are light blue in color, are less efficient than monocrystalline panels, but they are also cheaper. Monocrystalline panels, which are darker in color, are more space-efficient. If you have a limited area on a roof, we’d recommend monocrystalline panels to be able to make the most out of a small space.

  • How many solar panels do I need?

    To determine what size system will best fit your needs, make a list of all the appliances and devices you plan on running. The main appliances to take into consideration when addressing energy needs may include a TV, lighting, water pump, laptop, fans, microwave, and refrigerator. 

  • How do I maintain solar panels?

    Solar panels are low-maintenance. We encourage you to wash off the panels at least once a year to remove any dirt or other residue that may have been collected. In the winter, use a snow brush to remove snow from the panels (although panels generate enough heat to typically melt off most snow.) In the fall, we’d recommend brushing off any leaves that may collect on the surface of the panels.
