Description

Horizontal Linkage Single-Axis Photovoltaic Tracker

technical field

The utility model relates to a photovoltaic tracker, in particular to a linked single-axis photovoltaic tracker, which belongs to the technical field of solar energy utilization.

Background technique

At present, international energy issues have become the focus of attention of all countries. The effective use of fossil energy and the development and utilization of new energy have become the research focus of scientists. With fossil fuels decreasing day by day, solar energy has become an important part of the energy used by human beings and has been continuously developed. The utilization of solar energy has two ways: passive utilization (light-to-heat conversion) and photoelectric conversion. Solar power generation is a new type of renewable energy. Solar power has become the first choice for clean energy.

In response to China's "Twelfth Five-Year Plan" to "promote the transformation of energy production and utilization methods". As of 2015, the domestic installed capacity is expected to reach 13GW. Currently used photovoltaic power generation devices are mainly used: fixed power plants, tracking power plants, home power plants, off-grid power plants and other types. Various large-scale power stations adopt centralized power generation, which means that a large amount of land area needs to be concentrated to meet the requirements of centralized power generation. Among them, the single-axis photovoltaic tracking power station can increase (compared with the fixed-angle photovoltaic power station) 20-30% of the electricity. It is more conducive to recovering costs in the short term.
