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...
In the design of solar power stations, the tilt angle of the mounting system directly determines the annual light-capture efficiency of the panels and is a key hardware factor affecting electricity generation. Many project owners and contractors have long been torn between the question of whether fi...
There is no uniform standard for the thickness of roof trusses; they must be custom-designed to match the roof type, span length, local wind and snow loads, and operating environment. Selecting the appropriate model based on specific requirements is the safest, most cost-effective, and most professi...
As the load-bearing framework of a photovoltaic system, the thickness of the mounting profiles directly affects structural strength, wind and load resistance, and safety—making it a key consideration during selection. However, thicker is not necessarily better. Blindly increasing thickness no...
Numerous engineering case studies have shown that the rapid rusting of scaffolding is by no means solely due to “harsh environmental conditions”; rather, the core issues lie in three major industry malpractices: cutting corners in construction, using substandard materials, and non...
The design service life of a photovoltaic power plant is generally 25 years or more. As the core load-bearing structure of the plant, photovoltaic mounting systems are constantly exposed to the elements, enduring year-round exposure to sunlight, rain, temperature fluctuations, and harsh envir...
In a complete photovoltaic mounting system, clamps and rails are essential core components.
PV Clamps: Locking Components for Securing Solar Panels
PV clamps are hardware components used directly to secure and fasten solar modules. They are the most basic and widely used components in solar power p...
