Embodiment 1

[0023] like figure 1 , figure 2 As shown, an above-water solar photovoltaic power generation system according to the present invention includes a plurality of solar cell assemblies 1 arranged in arrays, and an above-water photovoltaic array support platform 2 floating on the water surface for fixing each solar cell assembly. Each array is arranged The solar cell modules 1 are connected to form a photovoltaic array, and the photovoltaic array is installed at a position above the height of the water wave. Power grid or local load, the grid-connected connection method includes direct connection to land grid, or power transmission connection through submarine safety transmission line, and the photovoltaic system balance device and grid-connected inverter 3 are placed in the equipment compartment 5 . The solar cell module 1 can be a monocrystalline silicon solar cell module, a polycrystalline silicon solar cell module, or a quasi-single crystal solar cell module.

Embodiment 2

[0030] This embodiment is basically the same as Embodiment 1, the difference: as image 3 , Figure 4 As shown, this embodiment is an implanted fixed-type outlying island solar photovoltaic power generation system on water. The photovoltaic array formed by connecting the solar cell modules 1 arranged in each array is connected to the photovoltaic charge-discharge controller and the storage battery pack or The off-grid inverter 3' connection is used to supply DC or AC loads on water or offshore.

[0031] In addition, the truss connection structure 22 is fixed to the bottom of the water through the underwater support 8'.

Abstract

The invention belongs to the field of photovoltaic manufacturing and application, and particularly discloses an overwater solar photovoltaic power generation system. The overwater solar photovoltaic power generation system comprises a plurality of solar cell assemblies which are arranged in an array and an overwater photovoltaic array trestle table used for fixation. The solar cell assemblies are connected to form a photovoltaic array. The photovoltaic array is connected into a public supply network or a local load through a cable via a photovoltaic system balance device and a grid-connected inverter, or is connected with a photovoltaic controller and a storage battery pack or an off-network inverter through a cable and is used for supplying electricity to a direct current load or an alternating current load on water or off shore. By means of the overwater solar photovoltaic power generation system, a solar photovoltaic power generation system can be installed on the surface of a water area such as a reservoir, a lake, a river and the sea; by means of fully utilizing the overwater sun exposure area with good solar irradiation conditions, the restriction on the installation area of the solar photovoltaic power generation system due to the facts that land resources are limited and land cost is high can be overcome beneficially, and the concept that a large or ultra-large photovoltaic power station is built at a coastwise water area to provide electric power for coastwise regions or cities nearby can be popularized beneficially.

Description

technical field [0001] The invention belongs to the application field of photovoltaic manufacturing, and specifically discloses a solar photovoltaic power generation system on water. Background technique [0002] Solar photovoltaic power generation is a very promising renewable clean energy. At present, a large number of photovoltaic power generation and solar photovoltaic power generation systems have been built on land, but solar photovoltaic power generation systems are rarely built on water such as reservoirs, lakes, rivers, and oceans, which wastes 71% of the surface of the earth's surface. The popularization and application of solar photovoltaic power generation system. Contents of the invention [0003] The object of the present invention is to overcome the geographical limitation of the application of the prior art and provide a solar photovoltaic power generation system on water, which can realize the utilization of the sunshine area on the surface of water areas...
