The Victron Energy 305W-20V Mono Solar Panel is a premium monocrystalline PV module designed for high output in residential, off-grid, vehicular, or hybrid solar systems. Engineered with advanced materials and precision manufacturing, it delivers excellent performance even in low-light and high-temperature conditions. With its substantial 305W nominal power, robust frame, and excellent warranty, this panel is built to last and excel.

Whether you’re powering a 24V battery bank, a MPPT charge controller, or building larger solar arrays, this panel offers reliable power, solid structural integrity, and long-term performance. It’s a strong choice for homes, farms, mobile setups, or any system where dependable solar generation is needed.

Key Features:

• Premium monocrystalline solar cells for high efficiency and improved performance under shading or partial light conditions
• Strong nominal power rating of 305 Watts, enabling higher energy yield per panel 
• High voltage output suitable for stringing or using with high-voltage MPPT controllers (Vmp ≈ 32.5 V; Voc ≈ 39.7 V)
• Low temperature-coefficient to mitigate performance loss under heat
• Durable frame and tempered glass for mechanical strength, resistance to wind, snow, and hail
• Waterproof junction box and bypass diodes to maintain power output even when parts of the panel are shaded
• Long product and performance warranties: 5 years for materials and workmanship; ~10 years for ~90% power, ~25 years for ~80% power retention
