Product Overview
Ballasted flat roof solar mounting holds the array down with precast concrete weights instead of roof fixings — the membrane stays untouched and warranty risk drops to zero. Aerodynamic base trays reduce ballast weight by up to 30%.
The system sets a 10° or 15° tilt optimized for low-latitude sites and wind zones. Ballast pads are sourced locally near the project to cut freight, while we supply trays, rails, clamps and a full ballast calculation per roof zone.
Key Features
- Zero roof penetration — membrane and warranty untouched
- Aerodynamic trays — 30% less ballast than flat designs
- Local ballast sourcing — we ship structure, ballast is bought locally
- 10° / 15° optimized tilt — low-latitude yield balance
- Zone-based ballast map — edge and corner zones calculated for you
- Fast row installation — snap-together trays and shared rails
Application Scenarios
Ideal for these flat-roof projects:
- Membrane-roof warehouses — TPO / PVC / EPDM membranes
- Concrete rooftops — offices and commercial buildings
- High-wind city sites — zone-calculated ballast layouts
- Rented buildings — removable, reversible installation
Configuration Options
- Tilt — 10° / 15° (east-west 5° optional)
- Ballast type — precast concrete blocks, locally sourced
- Tray material — HDG steel or recycled PP
- Rail — AL6005-T5 or HDG steel
- Layout — south-facing or east-west

Frequently Asked Questions
What is the MOQ for ballasted flat roof solar mounting?
MOQ is 50 kW of structure. Ballast blocks are specified locally — we provide the weight map.
How much weight does it add to my roof?
Typically 12-25 kg/m² including modules; we issue a load summary for your structural engineer.
Does it work on east-west layouts?
Yes — the 5° east-west version maximizes roof density.
Lead time?
10-15 days for structure; ballast sourced locally saves 1-2 weeks.
