SOLAR RCC ROOFTOP STRUCTURE

About SOLAR RCC ROOFTOP STRUCTURE

A Solar RCC Rooftop Structure refers to the structural system used to mount solar panels on the Reinforced Cement Concrete (RCC) rooftops commonly found in residential, commercial, and industrial buildings. This system supports solar photovoltaic (PV) panels and ensures optimal orientation, safety, and longevity.

Heres a breakdown of the key elements involved:

Components of a Solar RCC Rooftop Structure

1. Mounting Structure

   • Material: Usually made of hot-dip galvanized iron (GI), mild steel, or aluminum to prevent corrosion.

   • Types:

     • Fixed tilt: Panels are mounted at a fixed angle.

     • Adjustable tilt: Allows seasonal tilt adjustments.

     • Ballasted: No roof penetration; uses weights.

     • Penetrative: Anchored to the roof via fasteners or chemical anchors.

2. Solar Panels

   • Typically monocrystalline or polycrystalline.

   • Mounted on frames to optimize sun exposure.

3. Anchoring Mechanism

   • Chemical anchors or grouting into RCC for stability.

   • Ballast blocks (concrete or pre-cast) to avoid drilling in some cases.

4. Wind Load Resistance

   • Must be designed as per IS 875 (Part 3) to withstand local wind loads.

   • Critical in high-rise or coastal areas.

5. Tilt Angle

   • Optimal tilt depends on geographic latitude; for India, its typically between 1030.

   • Ensures maximum solar exposure throughout the year.

6. Walkway & Maintenance Path

   • Space provided for cleaning and inspection.

7. Earthing & Lightning Protection

   • To protect both equipment and the structure from electrical surges and lightning.

RCC Roof Considerations

• Structural Load: Roof must be assessed to carry additional loads (1520 kg/m).

• Waterproofing: Ensure proper waterproofing before anchoring to prevent leakage.

• Shade-Free Area: Rooftop must have minimal shadowing from nearby structures, water tanks, or trees.

Advantages of Solar on RCC Roofs

• Utilizes unused space.

• Reduces electricity bills.

Corrosion-Resistant & Durable Design

Our solar RCC rooftop structures use either hot dip galvanization or powder coating, offering superior protection against harsh weather and corrosion. Stainless steel fasteners and ROHS/ISO certified fabrication ensure lasting performance and environmental compliance, making the system ideal for long-term rooftop installations.


Flexible Installation & Panel Compatibility

With anchor bolt or foundation-less ballast mounting options, installation adapts to varying site conditions. The structure accommodates both landscape and portrait orientation and fits all standard crystalline and thin film solar modules, making it customizable for different project needs and maximized power generation.


Safety, Efficiency & Easy Maintenance

Designed for high structural efficiency (>90%) and safety, the system includes wind load resistance up to 180 km/hr, earthing/grounding lugs, and fire resistance. Assembly and maintenance are straightforward, aided by disassembled eco-friendly packaging and a comprehensive installation manual.
