30W Monocrystalline Solar Panel

Victron Energy 30W Monocrystalline Solar Panel (SPM040303603) This compact PV module provides stable charging of 12V batteries in small photovoltaic/off-grid installations. It excels in applications requiring reliability, mechanical durability, and efficient operation, even in low-intensity sunlight. Ideal for campers, boats, and vehicles.

• High efficiency in difficult conditions: Low voltage temperature coefficient improves operation at high temperatures, and very good light sensitivity increases yields at low sunlight levels.


• Less shading losses + safety: Bypass diodes reduce power loss in partial shade, and a sealed, waterproof junction box increases reliability in the field.


• Durable construction and long warranties: High-transmission tempered glass, anodized aluminum frame, EVA encapsulation, and a multi-layer backsheet meet safety requirements. A 25-year power warranty and a 5-year materials/workmanship warranty are included.


• Resistance to external conditions: permissible surface load of 200 kg/m² and hail resistance of 23 m/s (7.53 g) increase the safety of installation on the roof.


• High transmission tempered glass: increases the module's stiffness and impact resistance, which translates into better durability in mobile applications.
