A ship with solar panels will not sink

Could solar power power a ship's lights at night?

EMP previously tested Furukawa’s batteries on a vessel in Greece. During the day, solar panels recharged the batteries, which keep the voltage stable and could directly power the vessel’s lighting load. The batteries could also store the excess solar power to keep the lights on at night.

Can solar panels be used on EMP sails?

Marine-grade solar panels along the face can supply electricity for onboard lighting and equipment. Greg Atkinson, EMP’s chief technology officer, says the 4-meter-tall sail will undergo shore-based testing this year, in preparation for sea trials.

Will moving energysails affect solar power?

Atkinson notes that moving an EnergySail (mainly to optimize its wind collection) may affect how much sunlight it receives, though the panels can still collect solar power when lying flat. The startup’s ultimate goal is to hoist about a dozen EnergySails on a tanker or freighter that has the available deck space.

How can a solar power system help a sailor withstand bad weather?

The Fukuoka-based firm is also developing an integrated system that includes deck-mounted solar panels; recyclable marine batteries; charging systems; and computer programs that automatically rotate sails to capture optimal amounts of wind, or lower the devices when not in use or during bad weather.

Can solar power a sea trial?

For the sea trial, the startup plans to install a deck-mounted solar array with up to 25 kWp; battery packs; computer systems; and one or two EnergySails. Atkinson says it may take two to three years of testing to verify whether the equipment can weather harsh conditions, including fierce winds and corrosive saltwater.

How do solar panels work?

The rigid, rectangular device is slightly curved and can be positioned into the wind to create lift, helping propel vessels forward. Marine-grade solar panels along the face can supply electricity for onboard lighting and equipment.
