BIPV
“Mortise-and-Tenon Joint” is the culmination of Yu Energy’s bracket manufacturing technology and traditional Chinese wisdom. It ingeniously applies the principles of mortise-and-tenon joinery to the design, manufacture, installation, and use of aluminum alloy brackets. “Mortise-and-Tenon Joint” is a flexible structural system that leverages the inherent variability in materials and structures by pre-setting them as “pre-stress,” thereby effectively counteracting “external stresses” arising from meteorological and geological conditions as well as product wear and tear. Under the “Mortise-and-Tenon Joint” structure, “external stresses” and “pre-stress” interact with each other, thus establishing a holistic systemic relationship between the bracket itself and external variables.
When it comes to the issue of “waterproofing,” Yu Energy attributes it to four causal factors: “blocking, guiding, pressurizing, and supporting.” Under this causal framework, these variables establish a reciprocal relationship—characterized by both “external stress” and “prestress”—with specific product components. Together, they synergistically amplify force, creating an integrated system that is oriented toward “active waterproofing.” Through the principle of “mortise-and-tenon interlocking,” Yu Energy also endows each component with individual functionality within the overall architectural structure, thereby achieving a result where the whole is greater than the sum of its parts.

KEEP OUT WIND AND WATER FOR BAD WEATHER
1. Waterstop in the main sink
In response to adverse conditions caused by severe weather—such as violent storms, heavy rain, or heavy snow and ice—prevent dust, condensation, and splashing water from entering the interior.
2. Water-blocking and wind-resistant panel
Sealing and covering the gap between two adjacent gutters beneath the photovoltaic modules can effectively prevent rainwater and horizontal winds from entering under the modules, while also providing corrosion protection for the original roof components.

KEEP OUT WIND AND WATER FOR BAD WEATHER
1. Horizontal sink
Due to the small spacing between the upper and lower adjacent components, rainwater primarily drains naturally across the surface of the photovoltaic modules. A small amount of rainwater that accumulates on the top surface of the modules is collected in an organized manner and directed separately through open openings at both ends directly into the longitudinal main water channels located at either end. At both ends, specially designed self-waterproof drip lines have been installed; their cross-sectional shapes help reinforce the structural stability and strength of the original component’s frame along its length.
2. Vertical main water channel
This is the primary water-conducting component of building-integrated photovoltaics, and also serves as a critical structural element that bears the load of the PV modules. It channels rainwater collected by the diversion troughs into this main water channel, where, thanks to a predetermined slope, the water drains efficiently by gravity toward the lower end (the gutter).

KEEP OUT WIND AND WATER FOR BAD WEATHER
1. Single-shoulder compression block
Stainless steel bolts are used to vertically stack and load the components, flow channels, brackets, and flashing panels, ultimately securing them indirectly to the main gutter for locking. This ensures that the photovoltaic modules form a robust, integrated unit with the bracket system.
2. Diversion channel
The upper frame of the protruding “7”-shaped single-sided strip-shaped pressure-locking component on the cross-section serves to resist wind uplift.
3. Main sink pressure block
The contact surface features a toothed, anti-detachment design. M8×35T bolts are used to secure the roots of the gutter on both sides, effectively controlling the radial and axial movements of the gutter. This design is particularly suitable for roofs in areas with high wind pressure and can also prevent adverse effects caused by seismic sources.
4. Double-shoulder pressing block
Stainless steel bolts are used to vertically stack and load the piercing gasket, components, flow guide channels, brackets, and flashing panels, ultimately securing them indirectly to the main water tank for locking. This ensures that the photovoltaic modules form a robust, integrated whole with this bracket system.

1. Ridge (passageway board)
Supports the upper frame of the component at the ridge of the roof; provides a walkway for operation and maintenance; its cross-section is shaped with drainage channels on both sides to direct rainwater into the main gutter.
2. Bracket Assembly
The key components—pressure blocks for the component boards, guide grooves, and tray water collection troughs—are sequentially connected and positioned in an integrated manner, ensuring secure fastening. This design facilitates easy assembly through a modular, prefabricated approach.
3. Main sink support component
The top surface component of the main channel for BIPV supports can also serve as elevated rails as required, making it suitable for a variety of applications.
4. Main sink end connector
The gutters on either side of the ridge of the photovoltaic support structure are parallel and can be controlled, while the top surface provides support for cable trays.
5. Support tray
It primarily supports the controlled interaction between the baffle in the main tank and the side walls of the main tank.
