Solar Charging for Electric Boats

Challenge

The boat manufacturer required a solar charging system compatible with Torqeedo electric propulsion.

The solution needed to:

• Integrate into the vessel canopy structure.

• Withstand saltwater exposure and marine vibration.

• Support onboard battery charging.

• Maintain low profile and minimal added weight.

The system had to operate reliably in outdoor marine environments.

Approach

A solar module was engineered for direct integration into the canopy structure.

Thin-film modules were selected for lightweight integration and conformal mounting.

The canopy now serves dual function:

• Structural shading element.

• Solar charging platform for the propulsion battery system.

Marine-grade encapsulation was selected for long-term durability in saltwater and outdoor conditions.

Solution

The integrated solar assembly provides supplemental charging to the onboard battery system during operation and idle periods.

The system supports extended off-grid use without altering vessel architecture.
