Solar panels: large tree generates electricity
The FLINstripes solar modules are easy to attach to the tree and are designed to deliver up to 99 watts of power.

The Kiel-based company FLIN offers solar panels that can be placed on the mast or attached to the railing when anchoring. The new FLINstripes solar modules are a practical solution for generating electricity on a large boom. With an output of 33 watts per module and the option of combining up to three modules, batteries can also be charged while underway.

Simply attach the solar modules and you're done

Easy mounting on the large tree using Velcro makes installation particularly simple. The solar modules are supplied with pre-assembled Velcro. Sailors can attach them to the starboard or port side of the main boom in just a few minutes. The counterpart of the Velcro fastener must be sewn onto the lazy bag, so some preparatory work is required. The installation effort is nevertheless manageable. We recommend purchasing double the number of modules for double-sided installation. FLIN offers special modules for the port and starboard side. The orientation of the Velcro surfaces and cable connections then match the respective side. #

Particularly suitable for smaller yachts

The FLINstripes are particularly suitable for small to medium-sized sailing boats with limited space. The maximum output of just under 100 watts with three solar modules is sufficient to supply the refrigerator and navigation electronics with power. There is also space for three solar modules on the second side of the main boom. However, both sides will never generate electricity at the same time. However, it may be possible to generate electricity in the harbour in the morning and afternoon without having to actively track a solar module. The FLINstripes measure 119.5 x 22.6 x 3.1 centimetres each. The narrow design of the solar modules limits their output compared to conventional solar modules. Their great strength, however, is that they do not get in the way and do not interfere at sea and continue to produce electricity.

Good investment

One solar module costs 210 euros. An installation with three FLINstripes per side then costs 1,260 euros. A suitable solar charge controller must also be installed. The cost of fitting the lazy bags with a Velcro strap also adds up.
