The Victron Energy 190W monocrystalline solar panel (SPM041903903) is a compact single-phase DC generation module built for off-grid, marine and mobile installations. Measuring 1485 x 668 x 30mm and weighing 10.5kg, it fits spaces where larger panels won't, while keeping the efficiency benefits of monocrystalline cells. It's part of Victron's Series 4c range and aimed at installers working on space- or weight-constrained systems.

Victron 190W solar panel key features

• Rated output: 190W from 39 monocrystalline silicon cells.
• Compact frame: 1485 x 668 x 30mm, smaller than standard 60-cell panels.
• Weight: 10.5kg, easing structural load on roofs, vehicles and marine superstructures.
• Frame profile: slim 30mm aluminium frame for low-profile mounting.
• Series: 4c, designed to integrate with Victron charge controllers and monitoring systems.
• Traceability: GTIN 8719076070672, genuine Victron Energy stock.

Why the 39-cell layout matters

Monocrystalline cells produce more power per square metre than polycrystalline equivalents, which counts for a lot on a panel this size. The 39-cell configuration is less common than the 60 or 72-cell layouts used on residential roof arrays, and it puts the panel's voltage closer to what 12V and 24V battery systems and 15A to 30A MPPT controllers expect. That makes it a practical fit for narrowboats, campervans, off-grid cabins and other small remote power setups, and it works with the full range of Victron BlueSolar and SmartSolar MPPT charge controllers. Paired with a Victron MPPT and a GX device, output can be monitored through the VRM portal.

Applications

• Off-grid cabins and remote power systems running 12V or 24V battery banks.
• Narrowboat and canal boat solar charging.
• Campervan, motorhome and van conversion setups.
• Marine deck installations where weight and footprint are limited.
• Small agricultural or rural monitoring stations needing autonomous power.
• Supplementary charging for caravan and touring leisure batteries.

Installation notes

Fit this panel with a qualified electrician or MCS-accredited installer. Check the panel's voltage and current figures against your charge controller before wiring it in, and confirm the mounting surface can carry the panel's weight along with wind and vibration loads. It isn't intended for grid-tied export without the right inverter and G98/G99 compliance equipment. Use MC4 connectors and outdoor-rated DC cabling, installed to BS 7671 wiring regulations.
