Apparatuses for marine vessels to maximize solar energy collection are provided, along with systems and methods relating thereto. In some embodiments, an apparatus is mounted on the top of a marine vessel and extends its surface area, facilitating optimal sun exposure for solar panels. In some embodiments, prior to docking, the apparatus can be folded and rotated to fit within the original ship's profile, allowing for efficient cargo loading and unloading from the top as is standard in the cargo industry. In some embodiments, an apparatus comprises a plurality of solar panels and a plurality of skids configured to trail behind a stern portion of a marine vessel.
