Case Study: Reliable Panel Cooling Solution for Solar Manufacturing Line
Customer: Waree Solar
Location: Samakhiyali, Gujarat
Industry: Solar Panel Manufacturing
Application: Electrical Panel Cooling for Automated Solar Panel Production Line
Waree Solar, one of India’s leading solar module manufacturers, required a highly reliable cooling solution for critical control panels installed on their automated solar panel manufacturing line. The production environment involved continuous operation, high ambient temperatures, dust presence, and heat generated from sensitive electrical components such as PLCs, VFDs, servo drives, SMPS, and automation controls.
To ensure uninterrupted production and prevent downtime caused by overheating, HIMALAYA supplied specialized DURO Series Panel Air Conditioners for key automation panels across the line.
Supplied Solution
Panel 1: Solar Panel Framing Robot Panel
Product: DURO 1050 Panel Air Conditioner
The framing robot panel controls the robotic system responsible for aluminum frame fitting on solar modules. This panel houses servo drives, motion controllers, PLCs, and precision automation electronics that generate significant heat during continuous operation.
The DURO 1050 was selected to maintain a stable internal panel temperature, ensuring smooth robotic movement, accurate positioning, and prevention of unexpected shutdowns.
Panel 2: JB Fixing Panel
Product: DURO 550 Panel Air Conditioner
The JB (Junction Box) fixing station involves automation for accurate placement and fixing of junction boxes on the solar modules. Since this process requires consistent precision and continuous production flow, panel overheating could directly affect production quality.
The DURO 550 provides efficient cooling to protect sensitive electrical controls and maintain stable machine performance.
Panel 3: Post EL Panel
Product: DURO 550 Panel Air Conditioner
The Post EL (Electroluminescence Testing) panel manages inspection systems used after EL testing to identify micro-cracks, cell defects, and module quality issues. These inspection systems require stable electrical performance and controlled temperature conditions.
The DURO 550 ensures proper cooling for uninterrupted testing accuracy and reliable quality control.
Key Challenges
- High ambient temperature at Samakhiyali industrial zone
- Continuous 24x7 production environment
