Recommended Solar Setup for a Sailboat
This guide uses a baseline daily energy assumption of 1,500 Wh/day for a typical example sailboat configuration. This is a sizing estimate, not a site-specific electrical design.
Power Requirement Summary
- Estimated daily energy
- 1,500 Wh/day
- Estimated peak AC load
- 800 W
- Estimated solar need
- 375 W
- Estimated battery need
- 1,667 Wh
- Estimated inverter need
- 1,000 W
Why This System Size
Solar array sizing
Using an estimated daily demand of 1,500 Wh, 5 peak sun hours, and a 80% system efficiency assumption, the estimated solar array need is approximately 375 W.
Battery sizing
With 1,500 Wh of daily use and an assumed 90% usable battery fraction per cycle, the estimated storage need is approximately 1,667 Wh. This accounts for not fully depleting the battery bank on a typical day.
Inverter sizing
Based on an estimated peak AC load of 800 W and a 1.25× surge margin, the estimated inverter need is approximately 1,000 W. This provides headroom for brief startup loads above continuous draw.
System Challenge
Corrosive saltwater spray exposure and high mast shadow movement
Marine environments expose equipment to salt spray and moving shade from masts, rigging, and dock structures. Corrosion-resistant hardware and flexible mounting options are practical considerations for this use case.
