Floating photovoltaic device and floating photovoltaic power generation array formed by same

Abstract

The invention relates to a floating photovoltaic device and a floating photovoltaic power generation array formed the same. The photovoltaic device comprises component units and a central control bin, wherein the component units surround the central control bin and are in flexible connection with the central control bin; the central control bin gathers electric energy of the surrounding component units and supplies power to the outside intensively; adjacent component units are flexibly connected; the component units are provided with floating devices which can control the buoyancy force. A plurality of floating photovoltaic devices provided by the invention can be combined to form a larger floating photovoltaic power generation array; and the adjacent component units of the adjacent floating photovoltaic devices are connected flexibly. The invention has the advantages that the floating photovoltaic device can be arranged in water area safely and reliably and can control the wind and wave resistance of the floating device. A large photovoltaic power station can be formed by assembling the floating photovoltaic devices, the operation in the whole installation process is simple, and the structural cost is low.

Description

technical field [0001] The invention relates to the technical field of photovoltaic module structures, in particular to a floating photovoltaic device and a floating photovoltaic power generation array formed therefrom.

[0002] When photovoltaic modules are actually used outdoors, support devices are needed to ensure safe and reliable operation of the modules. Usually, photovoltaic modules are installed on land, but more than 70% of the water area on the earth has not been utilized.

However, the installation of photovoltaic modules on water areas needs to consider the harm of wind and waves to the photovoltaic system. US patent document US 2009 / 0133732 A1 discloses a floating solar device and method, which can realize the installation of photovoltaic modules on water areas. device, and installed on a solid keel, but the installation is more complicated and the cost will be high; European patent document WO 2011 / 100590 A2 discloses a floating solar power station, the design is similar to a honeycomb structure, and the movable pulley block and the floating device are used to The support frame floats on the water, and the photovoltaic modules are placed in the central area of ​​each hexagonal floating support frame. Large arrays can be assembled and combined by small arrays, but the wind and wave resistance and safety are slightly poor.
