Accurate steering adjustment method for photovoltaic solar panel

Abstract

The invention discloses an accurate steering adjustment method for a photovoltaic solar panel, which comprises the steps of (a) acquiring latitude and longitude coordinate information and current day data information; (b) acquiring local sunrise time and sunset time of the current day according to the latitude and longitude coordinate information and the data information; (c) calculating the time difference between sunrise and sunset according to the sunrise time and the sunset time; (d) acquiring the average angular velocity Y of the sun between sunrise and sunset; (e) enabling the photovoltaic solar panel to face towards the due east, timing from the sunrise time, rotating the angle of the photovoltaic solar panel every 15 minutes with the rotation amplitude being 15*Y at each time, wherein the photovoltaic solar panel rotates clockwise along the horizontal direction if the photovoltaic solar panel is located in the northern hemisphere, and the photovoltaic solar panel rotates anticlockwise along the horizontal direction if the photovoltaic solar panel is located in the southern hemisphere. The method disclosed by the invention is used for solving a problem in the prior art that the orientation of the photovoltaic solar panel is inconvenient to be adjusted, and a purpose of carrying out accurate control on angle adjustment of the photovoltaic solar panel is realized according to local specific sunlight conditions.

Description

technical field [0001] The invention relates to the field of solar power generation, in particular to a method for accurate steering adjustment of photovoltaic solar panels. Background technique [0002] Solar power generation is mainly divided into two types: solar photovoltaic power generation and solar thermal power generation. In 2011, the newly installed solar power generation capacity in the world was about 28 million kilowatts. The cumulative installed capacity reached 69 million kilowatts, and the global solar energy output value was 93 billion US dollars that year. Solar photovoltaic power generation is the use of solar cells to directly convert sunlight energy into electrical energy. The photovoltaic power generation system is mainly composed of solar cells, storage batteries, controllers and inverters, among which solar cells are a key part of the photovoltaic power generation system, and the quality and cost of solar panels will directly determine the quality an...
