Rooftop Solar Structure
Engineered steel mounting systems for RCC and metal rooftops — corrosion-resistant, wind-rated to 215 km/h, and built for fast installation and decades of dependable service.
RCC rooftop solar structures
Your rooftop solar plant is only as dependable as the steel beneath it — and on RCC (concrete) roofs that foundation matters most. ENSOL engineers RCC rooftop mounting systems to suit every roof condition, balancing cost and durability so you get exactly the strength your project needs, with no over-specification or compromise. Built to handle India's wind, heat and monsoon loads, our RCC structures deliver dependable, low-maintenance performance across a long service life. Explore the range below.
RCC Basic Mount
A reliable, cost-effective mount for straightforward RCC rooftop arrays. Its simple, modular design assembles quickly and can be relocated with ease, delivering dependable strength and long-term stability without unnecessary complexity — the right support exactly where it's needed.

RCC Bifacial Optima
Engineered for bifacial modules, with a layout that keeps the rear face exposed to reflected light while minimising shading and hotspots. The result is higher generation from both surfaces and longer, more consistent module life.

What it is
A rooftop solar structure is the engineered steel framework that holds photovoltaic modules at the optimal tilt above a roof, transferring wind, seismic and dead loads safely into the building structure. ENSOL fabricates these systems for industrial, commercial and residential rooftops, in both RCC-ballasted and metal-roof clamp configurations.
Why it matters
The mounting system determines how safely and how long a rooftop plant performs. A correctly engineered structure protects the modules through monsoon winds and decades of exposure, while a poor one risks uplift, corrosion and costly downtime. The structure is the foundation every other component depends on.
Engineering quality
Every member is sized to the project's wind zone and roof type using IS 875 wind loading and IS 800 steel design, then fabricated under an ISO 9001 quality system with full material traceability. Drawings are wind-load checked before fabrication begins.
Performance & benefits
Designed for wind speeds up to 215 km/h with selectable 10°, 15° and 20° tilt for optimal generation, finished in GP or hot-dip galvanised coatings to suit the environment, and shipped with the clamps and fasteners your crew needs to install quickly and consistently.
Engineered advantages
High Wind Resistance
Engineered and verified for wind speeds up to 215 km/h per IS 875, with uplift-resistant detailing.
Corrosion Resistant
GP and hot-dip galvanised finishes protect every member against moisture and coastal exposure.
Lightweight Design
Optimised sections keep roof dead-load low without compromising structural strength.
Easy Installation
Pre-engineered, pre-drilled members with matched clamps and fasteners speed up on-site assembly.
Low Maintenance
Galvanised steel needs little upkeep across its service life, reducing lifetime cost.
Long Service Life
Coatings deliver 15–25 years of dependable performance depending on grade and environment.

Rooftop structures, answered
Common questions from homeowners, EPCs and facility teams.
Both RCC (concrete) and metal/sheet roofs are supported. RCC roofs typically use ballasted or anchored bases, while metal roofs use clamp-based mounting matched to the sheet profile.
Rooftop structures are engineered for wind speeds up to 215 km/h, with the exact design verified against your site's wind zone per IS 875 Part 3.
Yes. Tilt angle, member sizing, coating and mounting type are all configured to your project drawings, loads and roof conditions.
GP suits low-moisture, easily maintained sites; hot-dip galvanised (HDG) is recommended for humid, coastal or high-exposure environments and offers the longest protection.
Expected service life is 15–25 years depending on coating grade and environment, with up to a 25-year warranty on Full HDGI builds.
Structures ship with matched clamps and fasteners, and ENSOL provides on-site installation support and guidance for assembly and erection.
