Manifesto What we believe

We make the steel that holds up solar farms — engineered against thirty years of weather, built on European-standard roll-forming lines, and shipped from one factory in Rajkot.

Origin

Siddhapura Solo Energy was founded in 2008 in Rajkot, in the steel-fabrication corridor of Gujarat. The country's first utility-scale solar projects were still on drawing boards. The brief from day one was narrow and unfashionable: do the structural steel underneath the panel — the bracket, the bolt, the bearing, the bay — and do it the way a bridge engineer would.

Eighteen years later that brief has not changed. The market around it has. Project sizes have grown from hundreds of kilowatts to hundreds of megawatts. Tracking has moved from optional to standard. Lender-acceptable structural design is now a financing question, not an engineering one.

Today

The factory operates European-standard roll-forming lines, in-house controller design, and a full structural engineering desk. Every product is designed against a thirty-year service life, with the worst-case load — not the average — driving the section sizing. The tracker controller is written and assembled on the same campus as the steel it commands.

Our customers are EPC contractors compressing construction timelines, developers chasing per-watt economics, and asset owners measuring service intervals in years. The thing that holds those three relationships together is the same: a structure that does what the engineer specified, for as long as the project owns the ground.

Heritage

From one roll-forming line to projects across India.

2008 → 2026
Eighteen years
2008
Founded

Siddhapura Solo Energy incorporated in Rajkot.

First roll-forming line commissioned. Early work supplies steel sections to ground-mount installations across Gujarat.

2012
Capability

First fixed-tilt mounting system shipped at scale.

Standardised module-mount design enters the catalogue. Galvanising and powder-coating brought in-house.

2015
Product

Seasonal-tilt mounting platform released.

Engineered for installations in the 5 – 25 MW range. Field-adjustable tilt without mechanical drives.

2017
Milestone

Crossed 500 MW of cumulative installed capacity.

Project portfolio expands beyond Gujarat into Rajasthan, Madhya Pradesh and Karnataka.

2019
R&D

In-house horizontal single-axis tracker (HSAT) platform.

First indigenously designed tracker controller, slewing-drive architecture and torsional-lock geometry. Made in India end to end.

2021
Quality

European-standard roll-forming lines commissioned.

Capacity step-change in throughput and section precision. Move to ZN-AL-MG coated steel as the default structural material.

2026
Today

Projects across India and beyond — from one factory.

Active sites across India, the Middle East and Southeast Asia. Eighteen years of structural manufacturing under one roof.

Doctrine

Six things we will not compromise on.

Written for engineers
Held to by every shop floor lead

The reference is the service life, not the warranty.

Every section, every fastener, every bearing is sized for thirty years of operation. Warranty intervals are commercial instruments; the structure underneath them is engineered against the full life of the project.

Design for the worst load case.

Slewing drives are specified against peak gust, not annual average. Cycle counts assume the most exposed bay on the most exposed row. Average-case design is how trackers fail in their seventh year.

Own the firmware.

The tracker controller is written, assembled and supported at Rajkot. We own the diagnostics protocol, the firmware update pipeline and the supply chain underneath both. No black boxes inside a thirty-year asset.

Stainless at every weather interface.

Mild steel fasteners are how five-year corrosion becomes a structural problem. Every joint that sees rain, dust or salt air uses stainless or ZN-AL-MG coated hardware as a default, not as an upgrade.

One drawing on the site is the same as in the office.

IFC drawings are released before mobilisation. Field engineers walk the first row of every project. Changes are circulated through revision control and not over a phone call. Construction time compresses when there is no ambiguity to resolve.

The factory is the unit of quality.

One factory, one engineering desk, one quality regime. Section tolerances are measured at the roll-forming line and not at the project site. The shop floor lead has a phone number that the project director can call.

The Factory

One campus, three disciplines.

Roll-Forming & Structural Steel

European-standard roll-forming lines run ZN-AL-MG and HDG coated coil into the rails, purlins, modules and torque tubes that make up the structural skeleton of every system we ship.

Engineering Desk & Quality

Structural engineers, draughtsmen and quality leads share one floor with the works. Project drawings move from design review to IFC release without a hand-off to a remote office.

How We're Organised

A flat shop with real engineers in charge.

Departments
Not a head-office org chart
Departments
Engineering Desk

Structural design & product engineering.

Structural engineers, draughtsmen and product designers responsible for the geometry, the load case and the IFC drawing pack. Every project routes through this desk before fabrication starts.

Structural designLoad caseIFC release
Manufacturing

Roll-forming lines, fabrication, galvanising.

Shop-floor leads run the roll-forming lines, the welding cells, the galvanising bath and the powder-coat booth. Quality is measured at the line, not at the project site.

Roll-formingGalvanisingQC
Controls & Firmware

Tracker controller and field-update pipeline.

Hardware engineers, embedded developers and a controls test bench. Owns the PCBA, the firmware, the SCADA integration and every diagnostic that runs on a Siddhapura tracker.

Projects & Field

Site-engineering and commissioning support.

Field engineers who walk the first row of every project, supervise commissioning, and stay through the first stow cycle. The handover is a person on site, not a document on a server.

CommissioningSite supervisionO&M handover
Sales & Solutions

EPC, developer and asset-owner relationships.

Solution engineers, not account managers. Every quote is paired with a load case, a delivery slot and a single point of contact through the full project life cycle.

Operations

Supply chain, dispatch and after-sales.

Procurement, logistics and after-sales inventory. Spares for every system we have ever shipped are inventoried at Rajkot for the full operating life of the project.
