When choosing a photovoltaic bracket installation method for a home solar system, you should consider the roof type, structural conditions, climate, budget, and maintenance requirements. The following are selection recommendations based on different installation methods:
I. Roof Installation Methods (Suitable for Most Homes)
1. Sloped Roof Installation (e.g., tiled roofs, metal roofs)
Recommended Method: Use a rail-type bracket or hook-type bracket, secured to the roof structure with clamps or hooks, without penetrating the roof.
Advantages: Easy installation, excellent fit, visually appealing, and good drainage.
Precautions:
Ensure the roof structure can support the weight of the bracket and components;
Avoid damaging the waterproofing layer, especially in older homes;
High-rise roofs require enhanced wind resistance.
2. Flat Roof Installation (e.g., concrete roofs)
Recommended Methods:
A: Concrete Counterweight Bracket: No drilling required, suitable for roofs with high waterproofing requirements;
B: Steel Frame: Overhead installation creates a sunshade, balancing insulation and space utilization;
C: Concrete Piers + Brackets: Brackets secured via concrete piers, suitable for roofs with sufficient load-bearing capacity.
Advantages: Adjustable tilt angle improves power generation efficiency; some methods also provide roof insulation.
Notes:
A: The roof's load-bearing capacity must be calculated;
B: Sufficient spacing must be maintained between modules to prevent shading;
C: Wind speed has a significant impact, requiring structural stability.
Ⅱ. Ground Installation (for homes with courtyards)
Recommended Methods:
A: Screw-in or hammer-in piles: Suitable for soft soil;
B: Concrete foundation mounting: Suitable for long-term installation in areas with strong winds;
C: Plug-in bracket: Easy installation and adaptability.
Advantages: Adjustable tilt angle, good ventilation, high power generation efficiency, and easy maintenance.
Notes:
A: Geological survey required to ensure a stable foundation;
B: Occupied ground space requires consideration of land use planning;
C: Suitable for homes with courtyards or in rural areas.
Ⅲ. Other Installation Methods (Special Applications)
1. Sunroom/Greenhouse Roofs:
Use lightweight aluminum alloy brackets to ensure both day-lighting and power generation.
2. Color-Tile Roofs:
Use aluminum alloy clamps (such as 470/760/820) with T-rails for quick installation and excellent wind resistance.
Additional Recommendations
1. Material Selection:
For home use, we recommend aluminum alloy (lightweight and corrosion-resistant) or hot-dip galvanized steel (high strength, suitable for windy areas).
2. Angle Design:
The recommended bracket tilt angle is ±5° relative to the local latitude to maximize solar radiation.
3. Maintenance and Warranty:
Choose a warranty-backed, corrosion-resistant bracket system to ensure a service life of at least 20 years.
