Solar tracker for water surface floating photovoltaic power generation and implementation method of solar tracker

Abstract

The invention discloses a solar tracker for water surface floating photovoltaic power generation. The solar tracker includes a plurality of floating type photovoltaic arrays arranged on water surface; photovoltaic assemblies are fixed on the floating type photovoltaic arrays; the side edge of each floating type photovoltaic array is provided with an adjustment water tank; the adjustment water tank is connected with a water pump; and the water pump is connected with a controller. According to the solar tracker of the invention, the quantity of water in the adjustment water tank can be adjusted through the water pump, so that gravity or buoyancy can be changed, the adjustment water tank drives the floating type photovoltaic array to move, so that an included angle between the plane of the photovoltaic assembly and a horizontal plane can be controlled, and therefore, the photovoltaic assembly can track solar altitude angles or solar hour angles in real time. With the solar tracker adopted, the problems of high cost and difficult maintenance brought about by electric machinery and transmission mechanisms adopted by an existing solar tracker can be solved.

Description

Technical field [0001] The invention belongs to the technical field of solar photovoltaics, and particularly relates to a solar tracker for floating photovoltaic power generation on water surface and an implementation method thereof. Background technique [0002] Solar power generation is an emerging renewable energy. It is favored by more and more people due to its advantages of no noise, no pollution, short construction period, safety and reliability. It is widely used and provides a new way to alleviate energy shortage and environmental pollution. Way out. Although the power generation method has many advantages, we have also found some disadvantages, such as the very large area required to build a solar power station. With the rapid growth of the world’s population, problems such as the lack of land resources have become more and more serious. The floating photovoltaic power generation system effectively breaks through the restrictions of land resources on photovoltaic power...

AI Technical Summary

Problems solved by technology

[0005] The traditional solar tracking system implementation method requires the use of mechanical mechanisms. There is friction between different parts, which increases energy consumption and reduces the life of the tracker. The problem of metal corrosion in floating photovoltaic power generation applications is aggravated.

The internal precision gears of the electric drive power unit show the disadvantages of high cost, short life and high maintenance requirements in application

The adjustable bracket cannot track the movement of the sun in real time, and a lot of labor is required in the adjustment process
