Sphere 200W & 250W Solar Panels Featuring Twin Cell Technology - Technical and Customer Service Guide
Overview
Sphere Twin Cell Solar Technology represents a significant advancement in solar power generation, specifically designed for the caravanning and RV market. Developed in Australia, this technology addresses the common issue of partial shading, which can severely limit the performance of conventional solar panels. Traditional panels experience a drastic reduction in output when even a small section is shaded. Sphere's innovative solution allows a single large solar panel to function as two smaller panels with isolated circuit paths, ensuring that one half can still perform at full capacity even when the other is shaded.
Key Features
- Twin Cell Solar Technology: Enhances performance in conditions of partial shade.
- Cell Efficiency: Offers 200W output from a footprint typically producing 180W, thanks to improved cell efficiency.
- By-passed Diodes: Increases reliability and minimizes power drops due to shading.
- Construction: Features an anodized aluminum frame resistant to rust, with pre-drilled mounting holes for versatile installation. The panels are covered with antireflective, high transparency tempered glass for added durability.
- Protection: An IP65 rated junction box provides complete protection against dust and water ingress.

Sphere Twin Cell Advantage
Sphere Solar Panels with Twin Cell Technology can continue producing 100-125W when shaded up to 50%, a significant advantage over traditional mono-crystalline panels which would cease to provide vital power under similar conditions.
Installation and Maintenance
- Ensure the panel is installed in a location where it can receive maximum sunlight with minimal shading.
- Regularly clean the surface of the panel with a soft, damp cloth to remove dust and ensure optimal performance.
- Inspect the anodized aluminum frame and junction box periodically for signs of wear or damage.
Troubleshooting
- Reduced Power Output: Check for shading or obstructions blocking sunlight to the panel. Ensure the panel surface is clean.
- No Power Output: Verify connections between the solar panel, charge controller, and battery. Inspect the junction box and cables for damage.
