Solar Power

Solar power is the quiet, maintenance-free way to keep batteries charged on a boat, RV or off-grid cabin. This section brings together everything for a complete solar system: marine solar panels (rigid, semi-flexible and flexible), solar charge controllers, panel mounting hardware and kits, portable solar power systems, solar battery chargers, complete solar charger kits, and wind and solar hybrid kits. Whether you are planning a 4kW off-grid system or a single bimini panel, the same building blocks apply.

How to plan a solar system

• Energy budget: add up daily watt-hours for every load on board.
• Array size: choose panels that fit the space and cover the budget with margin for weather.
• Controller: pick an MPPT controller rated for the array voltage and current.
• Batteries and protection: size storage and add fuses, breakers and disconnects.

Where should I start?

Begin with our solar panel guide, then browse marine solar panels.

Can eMarine design my system?

Yes. Our team helps customers size panels, controllers and batteries; reach out with your loads and mounting space.

Start with the panels: see our marine solar panels from Solbian, Solara, SLD Tech, Merlin and Meyer Burger.

For moorings and tenders, see our compact solar battery charger for boat batteries and electric outboards.
