The Eco Panther Series maintains a simple, lightweight design, enabling it to be fully electric and eco-friendly. It operates at 7.5 knots, consuming just 16.11 kilowatts of power. Equipped with 124 square meters of solar panels, the yacht’s efficiency is limited by vertical surfaces and hull shadows. As a result, we estimate a maximum output of 14 kilowatts on optimal days, rather than the full 18 kilowatts, taking a conservative approach to ensure realistic energy expectations.
