High-efficiency monocrystalline solar panel for compact 12V power systems

The 55W monocrystalline solar panel delivers reliable energy production in compact installations, making it ideal for marine, mobile, off-grid and auxiliary charging applications. Built with tempered glass, anodised aluminium framing and EVA encapsulated cells, it provides dependable performance in harsh outdoor environments while maintaining strong power delivery under heat and low-light conditions.

Key Features

  • 55W monocrystalline output: Efficient solar generation suited for battery charging, backup supply and small system loads.
  • Optimised operating voltage: Matched for regulated charging of standard 12V battery banks through solar controllers.
  • Low-light responsiveness: Maintains usable output even during overcast conditions and partial shading.
  • Thermal-stable power curve: Improved delivery in higher temperatures due to reduced voltage-loss characteristics.
  • Integrated bypass diode protection: Helps maintain power output when individual cells or areas are shaded.
  • Triple-layer EVA encapsulation: Ensures long-term mechanical protection and electrical insulation.
  • Tempered glass and anodised aluminium frame: Provides durability against salt exposure, impact, vibration and UV exposure.
  • Weather-sealed junction box: Supports secure cable connection and safe outdoor installation.
  • Extended service assurance: Includes long-term performance and material warranties for lifecycle confidence.

This 55W monocrystalline panel is well-suited for maintaining battery charge, powering remote loads and supporting DC systems in vessels, vehicles, small shelters or standalone solar kits.
