Our collaboration with Team Malizia – same as their overall approach to the IMOCA 60 project – has been a joint quest to achieve the maximum. From the first minute our engineers have been impressed by the level of professionalism and the pace Boris and his team worked on getting the boat ready for this year’s racing season.
Planning
Starting with a precise 3D CAD model of the yacht we first analysed the double curvatures of the hull and deck shapes to define possible panel installation areas. Following on, a shadow analysis allowed us to optimize string layouts, bypass diode positions and the custom distributed MPPT regulating system. Cable positions were adjusted to avoid penetration of load-carrying structures and minimize wire runs.
While 3D data is great for the initial planning process, experience has shown that reality often differs from the virtual model. For this reason we sent 1:1 prints of the full system to Lorient (France) which were then placed on their original positions to fine-tune shapes and cable positions – making it impossible to miss small details not shown on the model.
The result was a 1.149Wp system design using two different cell types – SP cells in the center and SX cells on the side decks, altogether weighing only 24,5kg including pre-mounted adhesive.
Installation
While the solar system and charge regulators were being manufactured in Italy and the USA, the Malizia crew carefully prepared all surfaces for the installation, removing the nonskid deck finish and stiffening cable feedthrough areas. After delivery, they removed the protective film on the back and used the pre-mounted adhesive to attach the system to the deck surfaces, followed by finishing the edges with UV-resistant sealant.
The wiring and installation of the 15 separate step-up MPPT charge regulators was finished just-in-time for the launch of the boat and its first sea-trials – the first 24h test has just been done, 100% powered by our solar system.

Big plans
After having experienced the motivation and quality of work the team has shown during the preparations, we can’t wait to finally see Malizia in action. Not only are we convinced to see great race results, we also hope for our solar system to help them to complete a CO2 neutral Vendee Globe and carry the important message of their Malizia Ocean Challenge, educating children and giving them the knowledge to become ambassadors for ocean protection.
