Client Overview
Sri Chandrakanth operates an 80 MT cold storage facility at Bilekere Hobli, Hunasur Taluk, Mysuru District — serving local farmers and agri-businesses for storage of perishable produce including vegetables, fruits, and agricultural commodities.
With electricity bills a major operational burden and frequent grid outages posing a serious risk to stored produce, a reliable and cost-effective energy solution was critical.
Project Background
Cold storage facilities are among the most energy-intensive operations in the agricultural supply chain. This 80 MT unit was consuming significant grid power 24/7 to maintain the required temperatures. A single power cut — even for a few hours — could lead to spoilage losses worth lakhs.
The combination of rising HESCOM tariffs, unreliable rural grid supply, and high energy costs made solar with battery backup the most logical and impactful solution.
Solution Delivered
Techedge designed and installed a 30 kWp hybrid solar system integrated with a 40.96 kWh DEYE LI-ion battery bank — engineered specifically for the critical uptime requirements of cold storage operations.
System Highlights
- System Size: 30 kWp On-Grid Hybrid
- Cold Storage Capacity: 80 MT
- System Type: Hybrid (Solar + Battery + Grid)
- Installation Date: September 2024
- RINAC Cold Storage: 80 MT
Total Battery Capacity: 40.96 kWh — sufficient to run critical cold storage loads through the night and during grid outages.
