Spectra 20W marine solar panel

20W semi-flexible solar panel, the most powerful in the Spectra range. Robust enough to walk on in soft soled shoes, this panel will keep even a large battery bank in tip-top condition while you are away from your boat or caravan, and in the summer can contribute significantly to your day-to-day electricity needs.

Marine grade materials are used throughout, and the panel will even flex gently to fit the curve of a deck or coachroof! Simply screw down using the four grommet holes in the corners, or glue with a marine-grade adhesive sealant.

The Spectra range of panels are fitted with diodes to prevent the battery discharging at night through the panel, so they can be wired directly to the battery bank. However, to prevent risk of overcharging we always recommend the use of a quality solar regulator. For any of the Spectra range, the SunGuard regulator is the most appropriate.
