Offshore chinampa type photovoltaic power generation system

Abstract

The invention discloses an offshore chinampa type photovoltaic power generation system, which comprises a photovoltaic assembly tandem, an inversion conflux module and a load that are connected in order; multiple photovoltaic assemblies connected by the photovoltaic assembly tandem in series generate power by utilizing solar energy; the load is accessed through a cable by a mini inverter and an AC conflux case; each photovoltaic assembly or each AC conflux case or two mini inverters are installed on a main buoyancy aid in contact with the water surface through a press strip; the main buoyancy aid inclines in a fixed angle facing the sunshine incident direction; the main buoyancy aid is connected through a first auxiliary buoyancy aid and is floated on the water in a complete offshore way. The sunshine in large area and high water level water area surface of rivers, lakes or seas can be fully utilized; the direct current can be directly converted into alternating current that can be directly; the electricity can be influxed and supplied to the load through the AC conflux case to provide power supply for various water loads conveniently.

Description

technical field [0001] The invention belongs to the technical field of photovoltaic power generation, and specifically refers to an offshore floating island photovoltaic power generation system. Background technique [0002] With the warming of the climate on the earth, the sea level continues to rise, the surface area of ​​the ocean water surface continues to increase, and the surface area of ​​the land continues to decrease. Since the industrial revolution, human society has burned coal and oil in large quantities, and emitted a large amount of carbon dioxide, sulfur dioxide, and particulate matter into the air, causing brown clouds to appear in the atmosphere on the earth, and smog to appear on the ground, resulting in land pollution. The frequency of acid rain and the acidification of water quality in the ocean have caused many changes in the ecological environment of the earth, such as air, water quality, ocean, soil, and lakes. In order to improve the ecological envir...

Problems solved by technology

At this stage, most domestic fish ponds and tidal flat photovoltaic projects mostly use photovoltaic module pipe pile foundation schemes. This existing water surface photovoltaic foundation scheme is not only time-consuming and costly, but also because some ponds, reservoirs and lakes have thick water bottoms. However, it is impossible to build a mounting frame for installing solar modules through piling, and it is impossible to promote it in rivers, lakes and seas where the water level changes greatly and the water area is huge.
