Abstract

The invention relates to a modular photovoltaic array and a power station thereof used on the water, which belong to the field of solar photovoltaic technologies. The modular overwater photovoltaic array comprises a floating body, wherein a connecting mechanism for installing a solar cell module is preinstalled on the floating body, the connecting mechanism comprises connecting pieces in X, Y and Z directions and allows the solar cell module to be installed quickly on land in a modular manner, the connecting piece in the Z direction can serve as a bracket of the solar cell module, and supporting rods of the connecting piece in the Z direction are of a hollow structure and can be used for placing conductive wire cables of the solar cell module. The modular overwater photovoltaic array can adjust angle of the light receiving surface of the solar cell module through regulating connectors in the bracket according to needs, is simple in structure, flexible in use and high in applicability, can be integrally installed in a modular manner on land then put into water, eliminates the difficulty of installation in water, save time and effort, and cannot collide with other floating bodies.

Description

technical field [0001] The invention relates to a modular photovoltaic array used on water and a power station thereof, belonging to the field of solar photovoltaic technology. Background technique [0002] At present, the photovoltaic power generation system is mainly installed on land, and only a small part is installed on the water surface. However, compared with the installation on the water surface, there are three disadvantages: one is that the land area is limited, while the water area is vast; the other is that the dust on the land is relatively large. , the surface of the solar panels is often covered with dust very quickly, which affects the conversion efficiency, while the sea surface is relatively clean; third, the land temperature is very high, and the temperature rise will reduce the conversion efficiency, while the installation temperature on the water surface is low, which is conducive to ensuring The conversion efficiency will not decrease with the increase ...
