Provided is a structure including a float, a solar panel module having a plate portion, and a supporting member fixed to the float and supporting the plate portion. The plate portion is supported to be movable relative to the supporting member, and a cushioning member is disposed between the supporting member and the plate portion.

Renewable Energy (RE) sources are already one of the cheapest sources of energy available today but are variable and infirm, and the open ocean offers many opportunities to generate energy by using various disparate sources and methods on a floating station. These energy stations converting renewable energy including solar, ocean currents, wind, waves and batteries and hydrogen to store energy and provide sufficient stable power and energy as required and available most of the hours. The invention claimed here is a system to capture energy from a combination of wind, solar and ocean currents, along with batteries for storage and later use and hydrogen creation, storage and use for generation. In addition, apparatus is described that provide mechanical stability and resilience in deep open seas and reliably survive storms and hurricanes. Also described is a method for overcoming intermittency of ensuring continuous and stable energy export from the station, and finally methods to continually operate RE station in the open seas even during storms and hurricanes and survive the high winds and waves.

The photovoltaic device includes a base, a photovoltaic power panel disposed on the base to produce electric power using sunlight, and a reflector formed on the upper surface of the base, being provided to accommodate water, and having a receiving groove defined by a bottom and a sidewall extending from the bottom such that the sunlight is refracted according to a difference in refractive index between the air outside the receiving groove and the water accommodated in the receiving groove, and to be reflected toward a lower surface of the photovoltaic panel through the bottom or sidewall. Accordingly, the photovoltaic device may effectively collect sunlight from both sides of the photovoltaic panel to improve power generation efficiency.
