7.5 Watt mobile solar panel for trickle charging

It’s ideal for exactly that: It compensates for charge loss during long periods of inactivity and protects your vintage car’s battery.

The no-load voltage of 18V enables effective charging even under suboptimal lighting conditions. The rated voltage of 12V matches the battery.

With 7.5 watts of power, just 2-3 hours of sunlight per day are enough to compensate for standby consumption. Full sun optimizes performance.

Yes, the panel comes with connection cables for the cigarette lighter, battery clamps and a DC connector. You can connect it directly to the 12 V battery.

It's plug-and-play: Just connect it and place it in the sun. No settings or additional charge controllers are needed.

The solar panel measures 337 x 337 x 17 mm and can be placed space-savingly on a shelf or similar surfaces.

Yes, the solar panel is suitable for 12V batteries in boats and can be attached, for example, to the deck.

Yes, the mobile solar panel is ideally suited to protect your boat's 12 V battery from deep discharge in winter storage. It compensates for the natural self-discharge over longer periods of standstill.

It works in diffused light too, but direct sunlight brings the full power of 7.5 watts. Even on cloudy days, it still provides charging current.

The connection cables are robust and weatherproof, allowing for long-lasting use.

The panel has a reliable discharge protection that prevents the battery from discharging via the panel. An additional external charge controller is usually not required for the intended trickle charging.

The 7.5 W power is achieved under optimal sunlight. In winter, the power may be reduced due to lower solar intensity and shorter days.

Yes, the gentle charging current compensates for the natural power loss in the cold. It prevents deep discharge but does not fully charge empty batteries.

On cloudy days, performance is significantly reduced. The nominal power of 7.5 W is only achieved with direct sunlight.
