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...
Many older factory buildings, older self-built homes, and early prefabricated concrete slab roofs were not originally designed to accommodate photovoltaic loads, resulting in relatively low overall roof load-bearing capacity. There are concerns that drilling holes could damage the existing wa...
Leaks in photovoltaic rooftops are, in most cases, not due to poor-quality mounting brackets, but rather result from a failure to distinguish between different roof types and the application of a one-size-fits-all approach to waterproofing. Many construction teams drill holes and apply sealan...
When installing solar panels, many property owners and contractors are most concerned about the risk of leaks caused by drilling holes in the roof and damage to the roof structure. In fact, it is not always necessary to drill holes when installing solar mounting systems on a roof. Currently, the ind...

Photovoltaic desertification control breaks free from the traditional dilemma of ‘high initial investment and difficulty in...
The key differences between the two types of mounting systems lie in their power generation gains, structural stability and O&M requirements. Selecting the appropriate system based on roof conditions, project scale and revenue requirements is essential to maximise benefits, and the specific sce...
