Frequently Asked Questions
Q What is a ballast-mounted solar mounting system for flat roofs?
A ballast-mounted solar mounting system is a non-penetrating racking solution that uses weighted ballast blocks (typically concrete) to anchor solar panels on flat rooftops. It eliminates the need for roof drilling, protecting the waterproofing membrane while providing a stable and adjustable structure for PV modules.
Q Why choose C-type steel rails for flat roof solar installations?
C-type steel rails made from high-strength Q355 steel offer excellent structural integrity, corrosion resistance (via ZM coating), and quick installation. The C-shape profile provides a reliable attachment point for PV modules and accommodates a variety of panel sizes and configurations.
Q What tilt angles are available for this flat roof solar mounting system?
The system supports adjustable tilt angles typically ranging from 5° to 30°. This flexibility allows installers to optimize the solar panel orientation based on geographic location and roof conditions, maximizing energy yield throughout the year.
Q What certifications does the Aisinee flat roof solar mounting system hold?
The system is certified to multiple international standards, including ISO, CE, SGS, AS/NZS, JIS, and ASCE7-10. These certifications ensure the product meets rigorous quality, safety, and performance requirements for global markets.
Q How long is the service life and guarantee period of this mounting system?
The Aisinee C-steel ballast flat roof mounting system is designed for a service life of 25 years, backed by a 20-year guarantee period. The ZM-coated steel construction ensures long-term durability even in demanding outdoor environments.
Q What are the typical lead times and shipping arrangements?
Lead times vary by order quantity: 1–7 working days for up to 1,000 sets, 7–10 days for 1,001–5,000 sets, 10–15 days for 5,001–10,000 sets, and subject to negotiation for orders exceeding 10,000 sets. Products are shipped from Xiamen Port, China, with inner wrapping and outer wooden case packaging. Payment terms include 100% TT and L/C at sight.
