All-in-One Solar Street Lighting – Karu, Ladakh

Project Overview

SM Infra Solutions successfully executed the supply and installation of 60 all-in-one solar LED street lights for an Indian Army regiment in Karu, Ladakh — a remote, high-altitude region known for extreme cold, strong winds, and prolonged winters.

The objective of the project was to deliver reliable, off-grid illumination in an area where conventional power supply is limited and weather conditions are severe.

Challenges on Ground

Executing this project in Karu required careful planning and field expertise due to multiple constraints:

Extreme climatic conditions with sub-zero temperatures
High-altitude environment affecting battery performance
Limited access to grid electricity
Strong winds requiring stable pole foundations
Short installation windows due to weather fluctuations

Each stage of the project demanded precision, safety compliance, and adaptability.

Our Approach & Execution

SM Infra Solutions supplied high-efficiency all-in-one solar LED street lights, mounted on 7-metre heavy-duty poles, specifically selected to perform in high-altitude and cold-climate conditions.

Special attention was given to:

Battery performance and solar charging efficiency
Wind-resistant pole foundations
Optimal light distribution for operational areas
Safe and compliant installation within defence premises

Our on-ground team coordinated closely with Army authorities to ensure smooth execution without disruption to daily operations.

Outcome & Impact

The project was completed successfully, delivering consistent, maintenance-free lighting that operates entirely on renewable energy.

The installed solar lighting system now provides reliable illumination during long winter nights, enhancing safety, visibility, and operational efficiency for the regiment.
