Description
The Victron Energy 20W Monocrystalline Solar Panel is a high-quality solar module designed for reliable energy generation in small off-grid applications and battery charging systems. Using 36 high-efficiency monocrystalline cells, this panel delivers excellent energy output while maintaining a compact footprint.
With a rated output of 20 watts, the panel is ideal for maintaining and charging 12V battery systems used in applications such as boats, caravans, campervans, lighting systems, monitoring equipment and remote installations. The panel performs well in low-light conditions, ensuring consistent energy generation even during cloudy weather or early morning and late evening sunlight.
Victron solar panels are engineered for durability and long-term reliability. The panel features a sealed waterproof junction box, high-performance bypass diodes and a robust aluminium frame, protecting the solar cells from environmental conditions and improving overall system performance.
The 36-cell configuration is optimised for charging 12V battery systems, making it compatible with Victron MPPT solar charge controllers and other solar charging systems.
Thanks to its compact dimensions of 275 × 450 × 25 mm, the panel can be easily installed on boats, motorhomes, caravans, sheds or remote equipment installations where space is limited but dependable solar charging is required.
Designed and manufactured to Victron’s high standards, the 20W monocrystalline panel provides efficient energy production, durability and long-term reliability for small solar power systems.
