Description

Three-dimensional fixed photovoltaic power generation equipment in road space

Technical Field

The utility model relates to solar power generation equipment, in particular to road space three-dimensional fixed photovoltaic power generation equipment.

Background

Solar photovoltaic power generation can be divided into three types, namely a fixed installation type, an inclination angle adjustable type and a complex automatic tracking system according to different installation modes of arrays. The total annual radiant quantity received by the photovoltaic array after the inclination angle adjustable type, the single-axis tracking and the double-axis tracking are higher than that of a fixed type. However, in actual engineering operation, the system operation efficiency is often less than the theoretical value for many reasons, such as: the mutual shadow casting among the photovoltaic modules and the operation of the tracking support are difficult to synchronize, and the improvement rate of the actual generated energy is slightly reduced. Meanwhile, the tracking support is high in construction cost, operation and maintenance cost, high in failure rate and low in reliability. Through technical improvement, the array fixed installation can be applied in large scale.

As is well known, both solar photovoltaic power generation and photo-thermal power generation are related to the light-gathering area, and a photovoltaic array for high-power generation requires a large area of space to install the photovoltaic array, so that large-scale photovoltaic arrays are often built in desert regions.

The solar photovoltaic power generation is safe and reliable, does not produce pollution and noise, and can be more flexible and can be operated safely and stably. The application of photovoltaic power generation enables the power utilization problem of remote areas and special areas to be effectively solved, and solar energy resources can be used anytime and anywhere. However, it is not practical to find an idle place suitable for installing solar photovoltaic power generation in a city, for example, a solar photovoltaic power generation system can be installed above a road, so that the solar photovoltaic power generation technology can be greatly utilized, and carbon neutralization can be realized earlier.
