Engineered for the seconddecade.

The warranty is a commercial document. The load case is an engineering one - and we design to the load case. Here is how a Siddhapura structure is reasoned, built, coated and proven before it ships.

Engineering That Builds Solar Infrastructure for Decades

Every Siddhapura Solo Energy structure is designed with a balance of strength, efficiency, and reliability. Our approach combines engineering expertise, precision manufacturing, and material excellence to create solar mounting systems built for demanding environments and decades of performance.

Our engineering focus ensures:

  • Strength without unnecessary weight
  • Faster installation through modular construction
  • Optimised designs for alignment and stability
  • Layouts tailored to every site condition
  • Foundations engineered for project requirements
  • Durability that withstands time and climate

Engineered for strength. Designed for efficiency. Built to last.

Three Commitments

What we will not compromise.

Held on every
project, every quote
01

Design to the site, not the spreadsheet.

Each structure is solved for the governing combination of wind, seismic, thermal and soil conditions measured at the project never a single national default applied everywhere.

02

Own the
control stack.

Hardware, firmware and diagnostics are designed and assembled in house at Rajkot. We use premium quality, latest technology developed by reputed vendors.

03

Coat for
the environment.

The coating class is selected from the site's corrosivity category, C2 to C5, and proven by accelerated test so a coastal array is never protected like an inland one.

Design Basis

Every structure carries four load cases.

Governing conditions
Verified per project
Wind
60m/s

Peak three second gust the structure is designed and stow tested against, including dynamic and torsional effects.

IS 875 Pt 3 · ASCE 7
Seismic
Zone V

Designed for India's highest seismic zone, with drive mounts and foundations detailed for the resulting demand.

IS 1893 · ASCE 7
Thermal
±60°C

Designed to accommodate temperature variations through controlled expansion and contraction.

EN 1991-1-5
Corrosion
C2 - C5

Coating system selected to the ISO 12944 corrosivity category for each site, from mild inland to coastal exposure.

ISO 9223 · 12944
Structure & Materials

Steel chosen for where it will stand.

Coating by corrosivity
Stainless at every weather joint
ZnAlMg

Zinc-magnesium-aluminium coating with several times the cut-edge barrier life of conventional galvanising, the default on structural members.

C4–C5 · structural members
AZ150

Aluminium-zinc coated steel with enhanced corrosion resistance, designed for long-lasting performance in demanding outdoor environments and solar applications.

ISO 9364 · structural steel
HDG

Batch hot-dip galvanising to a controlled coating mass for posts, foundations and heavy fabricated sections.

ISO 1461
SS 304 / 316

Every interface that sees weather is bolted with stainless hardware. No sacrificial plated bolt sits in the critical path.

A2 / A4 fasteners
Testing & Validation

Nothing ships on a spreadsheet.

Five gates
Before volume release
01

Finite-element analysis

Each structure is modelled and solved for the governing load combinations before a single section is rolled.

FEA
Every platform
02

Wind-tunnel verification

Aeroelastic behaviour, dynamic amplification and stow loads are verified in the wind tunnel for new table geometries.

Aeroelastic
New geometries
03

Full-scale fatigue cycling

Drives, bearings and bolted joints are cycle-tested on the bench to represent thirty years of field operation.

30-yr
Equivalent
04

Salt-spray & coating audit

Coating samples run accelerated salt-spray to confirm the specified corrosivity class is met before despatch.

ISO
9227
05

Prototype field trial

A field prototype is commissioned and monitored through a full stow cycle, in person, before volume release.
