Flexible, shaped Solar Systems
Our flexible Solar Panel solutions are individually designed for each cruising catamaran. We offer for most of the models different variants, called Essential, Comfort, and MaxPower.   

We developed flexible solar panel solutions which provide the maximum output on energy, even in hot, and sightly shadowed conditions. The high-end solar cells from SUNPOWER are glued on a thin fiber-glass, and covered with an anti-slippery cover - meaning that you can walk on our panels.

Stern Solar Systems
Our Stern Solar solutions are designed to work with high-end residential solar panels, the Sunpower 400W Maxeon 3. Four or five panels produce a total output of incredible 1600-2000 watt-power.

Our stern system allows to install additional gadgets, such as a Starlink-, TV, or NAVTEX antenna, or a rear-camera. Two or three full-RGBE lights, installed below the solar panels, provide a nice light at night.

Seamless Design ...

Our Stern Solar System is designed for a specific catamaran model. The shape of the frame, the poles, etc. have been designed in a way that they 'integrate' with the design of the catamaran. Even the color of the frame matches the yacht's color.

Frequently asked questions

  • Are the Flexible Solar Solutions resistant to salt-water, and extrem conditions?
    Yes - they are. We tested the solar panels on our own cruising catamarans in the Atlantic Ocean and the Mediterran Sea. All panels are also tested in our lab under extrem conditions. 
  • Can I walk on the Solar Panels?
    On our flexible Solar Panels you can walk with no restrictions.
    On our residential solar systems, we do not recommend to walk on them.
  • How is the electrical connection made on the Flexible Solar Solution?
    All panels have their electrical connections on the back-side, and are therefore not visible. This method gives a maximal protection of the connections
  • Was Solar Technology is used to transform the Solar Energy?
    We recommend to use the Solar- and Battery technology from Victron Energy or Mastervolt.
  • Do I need to upgrade the service batteries to Lithium?
    No, there is no need for upgrading the service battery bank to Lithium technology. However, for a maximal benefit we recommend to consider the installation of Lithium batteries. APASWISS is happy to develop an electrical concept tailored to your needs.
  • How long does it take from ordering to get the solution delivered?
    In case we have the templates for your yacht, we need between 2 and 4 weeks to produce the panels. For a stern-solar rack, we estimate a delivery time of 10 to 12 weeks, plus transportation.
  • Who is going to install the solution and how long does it take?
    A local service partner can install the solution with our guidance, or we will travel to the boat to install it. We normally operate from our bases in Switzerland, and Lefkas, Greece.
    Depending on the model of the yacht, we expect 2 days for installing the solar, and 1 to 2 days for installing the solar electronic (cables, MPPT controller, etc.).
