Solara S505M34. Yacht Solar Panel 115 Watts.

Top performance Solara S505M34 marine solar panel. Back-contact cells for very high efficiency.

This slim (4mm) yacht solar panel, part of the Solara Power M Series, was specially developed for maritime use, such as on boats, yachts, buoys and life rafts.  The panel is bendable by up to 3%, so it is also ideally suited for mounting on slightly curved surfaces.

If mounted on a solid base, it can be walked on without any risk of breakage.

The panel consists of monocrystalline high-performance cells encased in several seawater-proof protective layers. The connections to each individual cell are on the back so that more of the cell is exposed to sunlight. This means consistently high electricity yields even low light or diffused light conditions.

Developed for permanent operation in extreme heat and high humidity conditions.

The panel can be mounted with screws and glue. The screw holes can also be used for mounting on a bimini-top.

Solara thoroughly test each individual solar panel’s operational reliability, weather resistance and long-term endurance.

  • Monocrystalline back-connected high-performance cells for maximum electricity yields, even in low light conditions
