Solar Structure Installation at Kochi Metro Rail Ltd.
Project Overview
Kochi Metro Rail Ltd. (KMRL) has been a pioneer in promoting sustainable urban mobility. As part of its green energy initiative, KMRL planned to install a solar PV system on the rooftop of its Elevated Metro Yard, a crucial facility for metro train maintenance and parking operations.
While the scope was promising, the project presented multiple challenges — technical complexity, elevation constraints, and a strict budget under a public infrastructure scheme.
Initially, several large solar solution providers expressed interest. However, due to budget constraints and the elevated nature of the site, many reputed brands declined to proceed, citing feasibility concerns.
Strolar accepted the challenge and successfully delivered a custom-engineered solar structure solution within the same limited budget — without compromising on safety, performance, or project timeline.

Key Challenges
Elevated Yard Structure
The height and layout of the yard required precise load calculations and specialized mounting designs.
Operational Facility
Though not for passengers, the yard was busy with metro maintenance and required strict coordination.
Access Limitations
Work had to be scheduled around yard activity and space availability.
Budget Sensitivity
The project had a strict financial limit that many competitors considered non-viable.
Strolar’s Solution
Use a side-by-side layout or grid:
Pre-engineered modular structures
Wind and load analysis
Corrosion-resistant material
fit to elevated infrastructure
Rapid installation planning
Our Key Deliverables
Strolar provided hot-dip galvanized solar mounting structures designed to endure the coastal climate of Kochi and the continuous vibrations typical of a metro yard. The solution featured pre-fabricated modular components, allowing for faster installation and significantly reduced on-site work. The structure was engineered to be lightweight yet highly durable, meeting the specific load requirements of the elevated metro yard. We also conducted site-specific wind load and structural analysis to ensure the long-term stability and safety of the installation. Most importantly, the entire execution was planned with precision to ensure zero interference with daily metro yard operations, maintaining full functionality throughout the project.
Execution Highlights
The entire solar mounting structure installation was successfully completed in just 90 working days, showcasing our team's efficiency and planning. Strolar delivered a total capacity of over 2.89 MW through precision-engineered structures tailored to the elevated yard. Every aspect of the project adhered to Kochi Metro Rail Ltd.’s strict engineering and safety standards, ensuring a high-quality and compliant installation. Notably, Strolar achieved what many larger brands declined to attempt — completing the entire project within the exact budget that others had deemed unfeasible.
Client Testimonial
- When we initiated the solar project for our elevated metro yard, we knew it would be a technically challenging site with limited access, continuous operational constraints, and a strict budget framework. Many well-known companies evaluated the project but declined to proceed, citing feasibility and cost limitations. Strolar, however, approached the project with confidence and a clear plan. They delivered a well-engineered, cost-effective solution without compromising safety or quality. The professionalism and technical knowledge their team brought to the table were exceptional. We're extremely satisfied with the outcome and would be happy to collaborate with Strolar again on future sustainability initiatives.” — Project Manager, Kochi Metro Rail Ltd.
