Bendable for a Perfect Fit: Experience seamless installation on curved surfaces. With up to 240° of flexibility, this ultra-lightweight panel hugs the contours of your curved RV roofs, boat deck, or teardrop trailer, weighing 50% less than rigid panels.
All-Weather Endurance: Power your adventures through harsh elements. Featuring a premium ETFE coating and multi-layer bonding, this panel resists hail, yellowing, and cracking—ensuring consistent energy output and a longer lifespan than standard PET panels.
Heat-Reflective White Design: Keep your panels cooler for higher efficiency. The white backsheet reflects excess heat, preventing power loss in hot climates. Its clean aesthetic blends perfectly with yachts, boats, and white RV roofs for a professional marine look.
High-Power Off-Grid System: Generate up to 2kWh of daily power (under ideal conditions) with this 4-panel array. Perfect for charging large power stations or keeping your RV fully powered for days off the grid.
Professional System Setup: Customize your high-voltage array with ease. Designed for flexible series or parallel connections, this system allows you to scale up to 48V systems, making it compatible with most high-capacity solar controllers and battery banks.
What You Get: 4-Pack Callsun 100W Flexible Solar Panels (White), connection cables, user manual, our industry-leading 5-year warranty, and friendly customer service dedicated to supporting your off-grid freedom.
