2nd Saturday in Advent: Solar power at the railing - win the new FLINrail+ MultiVolt 100W+ from FLIN solar

The bifacial module provides enough energy to supply the fridge on board with solar power, for example. Lightweight, efficient and easy to install - for anyone who wants to be independent and sustainable when travelling on the water.

If you want to generate electricity independently and sustainably on board, the sophisticated solutions from FLIN solar are a must. The young North German company specialises in mobile, flexible solar systems for sailing yachts and boats - developed in Germany and inspired by real sailors. A particularly practical prize is now waiting for you in the YACHT Advent calendar: the new FLINrail+ MultiVolt 100W+ - a powerful railing solar module of the latest generation.

The FLINrail+ MultiVolt 100W+ is the logical further development of the popular FLINrail system. It can be hooked directly into the railing without tools and removed or aligned again in seconds if required. The solar module is bifacial, meaning it utilises light from both sides and can therefore generate significantly more energy than conventional modules, especially over reflective water surfaces. Thanks to a voltage Vmpp of 60.5 V, not only 12-volt batteries but also 24- and 48-volt batteries can be charged efficiently via MPPT controllers. This means it can be used universally - from small vehicle electrical systems with conventional consumers to large lithium battery banks for the electric motor.

A single FLINrail module supplies enough energy to fully power the refrigerator on board with solar power, for example. Thanks to the six integrated bypass diodes, the output remains constant even in partial shade - for example, if the module is partially covered by sails or rigging. The hotspot-free design ensures safety and a particularly long service life. Weighing only around three kilograms, the FLINrail+ is easy to handle and can be mounted on almost any boat. A matching carry bag is optionally available and enables safe, space-saving transport and storage below deck.

FLIN solar develops all its products in Germany and places particular emphasis on quality, practicality and sustainability. In addition to the relining modules in the FLINrail series, the company offers other innovative systems - including the FLINraft+ 300W+, an inflatable floating solar system that extends the solar area at anchor, and the FLINpole+, a solar system for mounting on the pushpit. Together they form a modular concept for self-sufficient energy on board - flexible, robust and practical.

So if you want to supply your on-board power supply with clean solar energy, the YACHT Advent calendar gives you the chance to win the new FLINrail+ MultiVolt 100W+ - and thus enjoy the freedom of generating electricity whenever the sun shines.
