The installation bracket structure for photovoltaic systems is an important guarantee for long-term, stable, and safe operation of photovoltaic power plants.
This article mainly classifies installation scenarios. Based on the actual situation of photovoltaic power plant construction over the years, photovoltaic systems are mostly installed in the following scenarios:
The installation of photovoltaic systems on tiled roofs is generally for residential use, especially villas and upscale rural residences in developed countries such as Europe, the United Kingdom, Australia, and high-end villas in China. The quantity of these installations is generally small, with most being small systems ranging from 2KW to 10KW.
The installation on tiled roofs should be designed according to the construction of the house (tile shape, material and span of support beams, slope, etc.), weather conditions such as wind and snow loads, and other information.
The installation of photovoltaic systems on colored steel tile roofs is mostly in industrial plants and is common in industrial parks. Different structures can be used for different types of colored steel tiles. It is recommended to use a clamping structure, which is easy to install, does not damage the roof, and is free of water leakage problems.
Installation on reinforced concrete flat roofs is also mostly in industrial plants. This type of roof mostly uses a installation form that does not damage the roof, and the required weight to be carried is determined by load calculations, with slit cement pressure blocks or loading trays used for pressure bearing fixation.
The ground installation of photovoltaic systems is mainly for large-scale photovoltaic power plants, which are planned and built on non-arable land such as deserts, Gobi, and wastelands in areas with abundant solar energy resources. The support forms for large ground photovoltaic power plants include fixed, single-axis tracking, and dual-axis tracking.
The use of tracking can significantly increase the power generation of photovoltaic systems, but it occupies a large area, and has high costs in terms of construction, operation, and maintenance. Therefore, the fixed installation form is still the main form, considering comprehensive cost-effectiveness.
