More features

• 【N-Type 16BB High-Efficiency Solar Cells】The Callsun 200 watt solar panel is built with advanced N-type solar cells and 16BB busbar technology, delivering up to 25% conversion efficiency. Compared to traditional P-type cells, N-type solar panels generate higher power output and better reliability, while the 16BB design reduces hot spots and hidden cracks — ensuring superior performance and a longer lifespan.
• 【Boost Your Power with Bifacial Technology】Callsun 400W bifacial solar panels feature a transparent backsheet that captures sunlight from both sides — direct, reflected, and diffuse rays alike. Unlike traditional panels with opaque backs, our bifacial design harnesses extra solar energy from the rear, increasing your total power output by up to 30%. Get more clean energy and maximize your solar system’s efficiency with Callsun.
• 【TwinCell Anti-Shade Technology】The Callsun 200W solar panel uses an innovative dual-module parallel design, splitting the panel into two independent halves. If one section is shaded by trees, buildings, or other obstacles, the other half continues generating power. This smart design boosts shading tolerance by up to 50% compared to conventional panels, delivering more reliable energy output and reducing the risk of complete power loss.
• 【Perfect Fit for Class B Vans & Easy Installation】Measuring 51.3 x 30.3 x 1.4 inches and weighing just 23.8 lbs, this 200 watt solar panel is designed to maximize power in a compact footprint — ideal for Class B vans and other tight rooftop spaces. Each panel features pre-drilled holes on the back for quick, hassle-free mounting on large rail mounts or other surfaces, making installation faster and more secure.
• 【Built to Last for Decades】Engineered to withstand harsh weather year after year, the Callsun 200W monocrystalline solar panel features ultra-strong tempered glass, a corrosion-resistant aluminum frame, and an IP68-rated junction box. Built for exceptional durability and long-lasting performance, it delivers dependable clean energy and long-term value for your home, RV, or off-grid system.
• 【Reliable Power Even in Extreme Heat】Callsun’s 12V 400W solar panel is engineered with a low temperature coefficient of just -0.3%/K, reducing power loss and ensuring stable, consistent performance even in scorching summer heat. This means more reliable power generation and better efficiency in high-temperature environments — perfect for hot climates and maximizing energy output when you need it most.
