India's most widely deployed rooftop solar structure. The Vlux RCC Rooftop Mount is engineered for concrete flat rooftops — from a 1 kW home system to a 5 MW commercial installation — using penetrating anchor bolts designed for maximum structural integrity without compromising your roof slab.
Concrete flat rooftops are the most common solar installation surface in India — found on homes, apartments, factories, schools, hospitals, and offices. The Vlux RCC Rooftop Mount is precision-designed for this surface, using L-feet or base plate anchor assemblies that distribute structural loads across the slab without concentrating stress at single points.
The system supports panels at tilt angles optimised for South Indian and central Indian latitudes — typically 10° to 20° — using hot-dip galvanised steel rails and 6061-T6 aluminium clamps. Pre-drilled holes and pre-assembled subframes mean installation is clean, fast, and fully reversible.
Ideal for residential homeowners, housing societies, commercial builders, schools, hospitals, government buildings, and industrial facilities with concrete flat rooftops. This is the right system when your roof can accept anchor bolts and you want maximum structural security for your investment.

Every feature listed here is a deliberate engineering decision — not a marketing bullet point. Here is why each one matters for your project.
L-foot anchors are ideal for most residential and commercial RCC rooftops. Base plate assemblies provide greater load distribution for larger commercial arrays. Both use EPDM rubber gaskets to prevent water ingress at penetration points.
Standard tilt angles of 10°, 15°, 20°, and 25° available — selected based on your rooftop latitude and available roof area to maximise annual solar yield without excessive wind loading.
For rooftops with limited area or complex shapes, Vlux also engineers east-west facing systems at lower tilt angles — allowing higher panel density per square metre with reduced wind load.
A typical 10 kW residential system is installed completely in one working day. Pre-drilled rails, snap-fit clamps, and pre-assembled mounting kits eliminate delays and reduce labour costs significantly.
All anchor points use EPDM rubber isolation gaskets to create a permanent waterproof seal between the mounting hardware and your roof slab — protecting your building's waterproofing envelope.
Vlux aluminium clamps accommodate all standard module formats from every major panel manufacturer — mono PERC, bifacial, half-cut, and full-cell in 60, 72, 96, and 120-cell configurations.
Every Vlux project follows a structured 4-stage process that eliminates surprises — from the first site visit to final commissioning sign-off.
