In this study, a passive vibration control method termed as translational root mounting method is proposed and investi-gated, for suppressing the low frequency vibrations of spacecraft solar panels. The translational root mounting method employs dampers installed at the roots of solar panels to dissipate the dynamic energy.
Abstract: The proposed paper highlights the performance analysis of the effect of vibrations on the flexible solar panel. The vibrations have been produced by vibration generator embedded on the rear side of the flexible solar panel for testing purpose.
Scientists in the U.K. have developed a system which makes panels vibrate to provide cleaning. The academics have conceded, however, they are yet to calculate the ‘sweet spot’ of mechanical stress to be applied. The process involves the attachment of a DC motor to the rear of panels.
The self-cleaning mechanism involves attaching a DC motor to the backsheet of a panel. A solar module was supported on four edges to emulate a system being excited by an unbalanced mass to induce vibrations, the researchers said, adding: “The set-up was arranged to be constrained firmly and allow vertical vibrations throughout the laminate.”
The back of the panel is a solid backing material, and the entire assembly is framed in metal, providing structure and the ability to mount the panel. The assembly of solar cells into panels is a precise and careful process that aims to maximize the efficiency and durability of the final product.
The configuration of solar cells within a panel plays a crucial role in maximizing efficiency. Beyond the traditional flat-panel designs, bifacial solar panels are gaining attention. These panels can capture sunlight from both the front and back surfaces, taking advantage of reflective surfaces below the panel.
At the heart of a solar panel’s ability to generate electricity is the photovoltaic (PV) effect. Discovered in 1839 by French physicist Edmond Becquerel, the PV effect is the process by which solar cells within the panel convert sunlight into electricity.
In this study, a passive vibration control method termed as translational root mounting method is proposed and investi-gated, for suppressing the low frequency vibrations of spacecraft solar panels. The translational root mounting method employs dampers installed at the roots of solar panels to dissipate the dynamic energy.
