Slope construction method in mountain forest area

Screw piles are driven vertically into sloping land

Construction to match the topography of sloping terrain

The power converters are fixed on a single pipe frame.

The back-fastening method eliminates the need for a person to climb on the top of the solar panel to install it, allowing for more secure installation. (Prevention of micro-cracks in the cells)

Solar cell backside fixing method hardware
The aluminum frame on the back side of the solar cell is clamped and fixed to the frame with special

metal fittings.

Ground-mounted frame

Structure

Aluminum alloy (6005-T5)
Anodic oxidation of the surface (Alumite treatment)

Configuration

Horizontal and vertical lines of solar cells
2 to 4 Tiers
Special order available for 5 to 6 tiers

Installation angle

5° to 60° supported.

Supported solar cells

Crystalline and other types of solar cells
30mm to 50mm thickness supported

Strength

Resistance to wind 40m/s
Resistance to snow 1.5kg/m2 (approx. 25cm)

No need to drill holes for fixing on the rooftop, easy installation, simple placement construction. Inclination angle 10°
When the tank is filled with water, it weighs about 150kg/piece and can withstand the standard typhoon wind pressure (34m/S) prescribed by the Ministry of Land, Infrastructure, Transport and Tourism.

Vertical installation on the wall in front of the factory building
Accessory equipment, such as power converter, is installed on the roof to ensure ease of maintenance.

Installation completed

A total of 162 solar cells were installed in 9 units with 18 solar cells per unit. The wiring is kept in the cable rack (W=200) to improve the appearance.
The structure has a slope of approximately 3° to eliminate water puddle and is facing south.

Small power converter 9.9KW x 2 units Dedicated installation rack
Power converter foundation block 120×120×600

The rooftop is waterproofed with exposed asphalt, so the frame units are placed on top of t5.0 anti-vibration rubber.
The weight of each unit is 1000kg to withstand wind pressure. (Loading weight of 40kg/m²)

The placement foundation construction method can be used in places where there are buried cultural properties or industrial wastes under the ground and the land cannot be dug or removed.

The concrete is about 0.7m³. The weight of the concrete is about 1,500kg, and the pull-up load of the concrete is 400kg per foundation in typhoons, etc., and therefore, more than triple safety performance can be ensured.

Auxiliary equipment such as the power converter is fixed with the solar cell frame and the lower round foundation.

The construction cost can be greatly improved by streamlining the construction method, lowering the cost and eliminating the need for residual soil disposal.
Various soil types and strengths can be supported by using long or short screw rods.

Taking advantage of the characteristics of chemical anchors, the construction can be done with a simple method without building a foundation due to the waterproof performance and adhesion to concrete.
