What auxiliary systems benefit from marine solar power?

Marine solar power can benefit various auxiliary systems on boats and ships, including watermakers, air conditioning, refrigeration, communication equipment, navigation systems, and propulsion systems. These systems require reliable power, making marine solar power a viable alternative or supplement to traditional fossil fuel-based power sources. By harnessing solar energy, vessels can reduce their environmental impact and operating costs.

Powering Watermakers

Marine solar power is particularly well-suited for powering watermakers, which convert seawater into fresh water. A typical 10 kW solar array can supply enough power to run a 1,500 GPD (gallons per day) watermaker, providing a vessel with a reliable source of drinking water. By integrating solar power with a watermaker, vessels can significantly reduce their reliance on desalination plants or storage tanks.

Charging and Powering Propulsion Systems

Flexible solar panels can be integrated into boat hulls or superstructures to generate power for propulsion systems. A 20 kW solar array can charge a 120 kWh battery bank in 6 hours, providing enough power to propel a 40-foot boat for several hours. By leveraging solar power, vessels can reduce their fuel consumption and emissions.

Protecting Solar Panels from the Salt Environment

To protect marine solar panels from the corrosive effects of salt, specialized coatings and frames are used to shield the panels from seawater spray. A 1,000 sqft solar array can be protected with a waterproof coating that extends its lifespan by up to 20 years. Regular maintenance, including cleaning and inspections, is also essential to ensure the optimal performance of marine solar panels.
