In areas prone to high winds—such as coastal regions, open Gobi deserts, and wind-prone sections of plains—wind loads are often the primary cause of failure in photovoltaic mounting structures. Many projects simply rely on wind speed as a reference, neglecting factors such as wind press...
The penetration rate of tracking mounts has been increasing year by year, and the combination of bifacial modules with single-axis tracking has become the mainstream solution for large-scale flat-ground solar farms. This has led many customers to wonder: Will tracking mounts gradually replace fixed...
The power generation efficiency of photovoltaic modules is highly sensitive to temperature; for every 1°C increase in module temperature, the output power decreases by a certain amount. The key advantage of ground-mounted racks is that they provide a ventilation gap beneath the modules, which h...
Many solar projects fail to generate as much electricity as expected. After ruling out module and inverter malfunctions, the problem often lies in the design of the mounting structure spacing. Localized shading not only reduces power generation but also causes hot-spot effects, which accelerate mod...
As a fundamental component of solar power plants, raw material costs account for 70% to 80% of the total cost of photovoltaic mounting systems. The core materials are steel and aluminum alloy, supplemented by stainless steel fasteners, zinc-aluminum-magnesium-coated materials, and other components....
Many property owners and contractors have questions: Since aluminum alloy brackets are lightweight and made of a soft material, are they more prone to deformation than carbon steel brackets? The answer is: Aluminum alloy brackets that meet national standards will not deform under normal use; bendin...
Low-cost solar mounting systems on the market that are priced significantly below market rates commonly suffer from issues such as cutting corners, substandard workmanship, and materials that fail to meet specifications. While they may seem to save costs in the short term, they can lead to multiple...
I. Ensuring Power Generation Efficiency and Preventing Power Reduction Due to High Temperatures
Photovoltaic modules exhibit a significant negative temperature coefficient; the higher the operating temperature, the lower the power generation efficiency. In summer, enclosed rooftops have extremely po...
In a complete photovoltaic mounting system, the rail serves as the core load-bearing beam and is the critical intermediate structure connecting the photovoltaic modules to the main mounting frame. While failures in most projects may appear to stem from issues with the modules, waterproofing, or win...
I. Prioritize Load Distribution to Prevent Concentrated Pressure at Single Points
The load-bearing capacity of older roof slabs is generally weak, and their local load-bearing capacity is extremely poor. If mounting brackets and counterweights are concentrated in the mid-span or weak areas of...
When installing solar panels on older roofs, the key challenges are roof deterioration, varying materials, and weak load-bearing capacity. There are significant differences in load-bearing capacity, waterproofing, and structure among different roof types, and generic mounting solutions can easily le...
Leaks caused by drilling holes in photovoltaic rooftops are not sudden problems, but rather the result of long-term accumulated risks. All water leakage issues can be traced back to specific construction defects, and the core causes can be divided into four points:
1. The waterproofing layer...
