Solar Powered Cruise Ships: The Future of Sustainable Travel?

Many cruise ships have solar panels. Solar energy is a great option for cruise ships because it doesn’t require any fuel and it doesn’t produce any harmful emissions. Plus, solar energy is a renewable resource, so it’s a sustainable way to power cruise ships.

Solar powered cruise ships may be the future of travel. With fuel prices on the rise and concerns about climate change, more and more cruise lines are looking into solar power as a way to reduce their carbon footprint and save money.

Some cruise lines have already begun to convert their ships to solar power, and others are in the planning stages. So what are the benefits of solar powered cruise ships?

Solar Panels on Cruise Ships – What Do They Look Like?

The panels are mounted on the top deck and the side of the ship. They may be in the form of rigid panels that automatically track the sun.

There are also some cruise ships being designed with solar sails. The Peace Boat project, Ecoship, is one example. The Ecoship is powered by 10 retractable sails that are expected to provide 4% of the required power. The sails’ maximum efficiency under ideal sailing conditions will be 10%.

Solar panels on a cruise ship can generate enough power to run the ship’s lights, waste management, and other electrical equipment for the passenger cabins and public areas.

What Are the Benefits of Solar Powered Cruise Ships?

Cruise lines are looking into solar power as a way to reduce their carbon footprint and save money. Some cruise lines have already begun to convert their ships to solar power, and others are in the planning stages.

The main benefits we see with solar powered cruise ships are:

Reduced Emissions

Solar power is a clean and renewable source of energy, so it doesn’t produce the greenhouse gases that contribute to climate change.

Reduced Costs

Solar power can also help cruise ships save money on costs because they can generate their own power rather than relying on diesel generators. Reducing fuel consumption also reduces the cost of running the ship.

Improved Air Quality

Solar powered cruise ships can improve air quality onboard by reducing the emissions of harmful pollutants generated by diesel engines.

More Comfortable Passengers

Since solar panels don’t produce noise or vibrations, they won’t disturb passengers who are trying to relax onboard. Less noise means more peace and quiet.

Generate Power While Docked

Another benefit of solar powered cruise ships is that they can generate power even when the ship is at the port. This means that the ship can still have power for lights and air conditioning, without having to use diesel generators.

It remains to be seen how many cruise lines will make the switch to solar power, but it seems likely that we will see more and more solar powered cruise ships in the future.

When a new cruise ship is being created they need to take the ship’s design into account. Future-proofing all the ships to include more efficient solar panels in order to reduce carbon emissions.

What Are Some of The Disadvantages of Solar Powered Cruise Ships?

There are some potential disadvantages of solar powered cruise ships and these need to be taken into account before the companies can start making the switch.

Solar Power Is Not Always Reliable

The amount of power generated by solar panels depends on the weather and time of day. So if there is a lot of cloud cover or it’s nighttime, the ship may not have enough power to run all its electrical equipment.

Solar Panels Are Expensive to Install

The cost will likely come down as solar technology becomes more advanced and more widely used, but it’s still a significant upfront investment for cruise lines.

Solar Panels Take up Space

They need to be installed on the roof or sides of the ship. The amount of energy used by a cruise ship means that a lot of solar panels are needed to generate enough power. This means that there may be less space available for other things, like passenger cabins or public areas.

Solar Panels Require Regular Cleaning and Maintenance

The panels need to be maintained and cleaned regularly in order to keep them running at peak efficiency.

If they get covered with dirt or bird droppings, the amount of power they generate will be reduced. Birds can also damage the panels if they try to build nests on them.

All of these factors will need to be taken into account before cruise lines make the switch to solar power, but it seems likely that solar energy will play an increasingly important role in the

So there are some potential disadvantages to solar powered cruise ships, but the benefits appear to outweigh them at this point.

It will be interesting to see how the cruise industry evolves over the next few years as more and more ships make the switch to solar power for a better future.

How Much Does It Cost to Convert a Cruise Ship to Solar Power

This is a difficult question to answer as it depends on a number of factors, including the size of the ship and the amount of power needed.

However, some estimates put the cost at around $500,000 per megawatt. So for a cruise ship that needs 500 kilowatts of power, the conversion would cost about $250,000,000.

While the upfront cost of converting a cruise ship to solar power may be significant, it is important to remember that solar power is free once the panels are installed.

This means that cruise lines could save a lot of money in the long run by making the switch to solar power.

Which cruise lines have started using solar energy, and what has been the response from passengers and crew alike?

How Much Money Can Be Saved by Using Solar Panels on A Cruise Ship

A typical cruise ship consumes around 500,000 kilowatts of electricity per day.

Solar panels can produce an average of 20% of this amount, so a cruise ship with solar panels would save around 100,000 kilowatts per day.

This amounts to $37,500 per day or $13.75 million dollars per year.

These numbers are only estimates, but they give a good idea of the potential savings that can be made by using solar energy on cruise ships.

What has been the response from passengers and crew alike?

Solar powered cruise ships have been met with overwhelmingly positive responses from both passengers and crew members.

Passengers appreciate the fact that they’re helping to


Final Thoughts

Solar panels are a great way to reduce the environmental impact of a cruise ship. By installing solar panels on a cruise ship, they can help power the ship and reduce the amount of pollution that is created.

Cruise ships are a major source of pollution, and by using solar panels, we can help make them more environmentally friendly.

Since solar panels are a good fit for cruise ships, they are sadly not yet a great fit for airplanes. Read more in our blog post about why airplanes do not have solar panels.
