- With power consumption being such a large concern as well as the desire to have some creature comforts for sailors especially when crossing oceans let's compare a couple of the most popular methods for harnessing nature's elements and turning them into power, solar power, vs wind power.

Our mission at HowToSailing is to introduce travelers to the serenity and sensational ventures of sailing. We are inspired to invite as many sailors as we can to join us to experience the magnificent world of sailing together. Once travel restrictions and social distancing guidelines dissipate due to Covid-19
There is no time limit or a specific date we have planned. Our main objective is to make meaningful memorable connections and share the simple joy of sailing with as many people as we can. We have a mission to build a community of fellow sailors through our TH-cam Channel, HowToSailing because we want to connect with others who have a love for sailing. Our goal with the channel is to simply create captivating content, construct a solid fan base with fellow sailors, and someday soon invite people from around the world on an adventure
HowToSailing is not an average sailing channel. We were inspired by the adventurous spirit of, Alex Rust of Chasing Bubbles, who had an endless thirst for travel and experiences. Sailing is a wonderful experience and worth sharing with others, so we aspire to someday begin the adventure. We want others to experience the delight, freedom, and exploration of sailing. It is all about the adventure, the moments that count for a one-of-a-kind experience. The excitement of traveling to a new location is riveting and represents the worth of cruising life as adventure awaits among every wave.
We want to share our passion for sailing with others and allow those who have a love for the sea to experience the freedom of sailing, reaching goals, and making memories in the miles of water we pass through. HowToSailing desires to introduce amateur sailors and travelers alike who would otherwise not be able to sail or experience being on a sailboat to share our adventures as a group and create meaningful memories unified by the power of the sea. It is our heart to see the world and all it has to offer, and this dream means more when we have others to come aboard and experience it with.
It is the freedom that we feel when we traverse unfamiliar seas that bring us to unique landmarks, introduce us to different people, and grant us exhilarating opportunities we could not have without sailing. At HowToSailing, we chase after meaningful memories and connections through sailing and the bliss it bestows on its travelers. We want to see the radiance of sunshine, the deep ocean blue waters, and the wildlife that surrounds our journey with others who have the same drive to explore as we do. Sailing is a once in a lifetime experience. It is unlike any other form of travel because it is a remote experience that requires a free spirit and a willingness to throw off the dock lines and just go for the sake of adventure. We started HowToSailing because we want other explorers to accomplish their sailing goals, experience the significance of sailing, and most of all, enjoy the voyage with us.

Both, one during the day and the other during cloudy days to help on
I agree 100%

Of course, I'd not mind adding a hydro-generator either (or that system that allows to use the propeller movement for the same purposes) . The more options the better.
In developing my houses alt energy, it becomes apparent to have a sustainable system you are best to include as many alternate sources as possible. Solar + Wind + Hydro + Stirling Engines + etc... then you don’t have to invest heavily in one system, and keep each component in a moderate budget. If you need 4kw of power, that’s a lot of panels, or an expensive turbine, and that potential won’t be realized all the time if you go with one system. If you have three sources and you split the load to 45% of your needs per thing, then each system will overlap, you would only need low to mid range products, and you will have a more consistent input. Hope this helps anyone 😸👍
You can supply the wind turbines with air as it moves with solar energy and have a combination of energy from both
The sunreef eco sailing line (though expensive) does it the best. It's a sailboat, with twin 35kw drive motors, up to 13kw of solar, a decent battery bank, the engines can recharge the batteries when spun in the water, and diesel generators for when solar and wind fail. So with limited motoring, you never have to use diesel, even for on board cooking, heating, lighting, power, or ac.
Love your videos ❣️
Tha k you so much
Yet another good video. Our boat came with wind (Air X - can be noisy) and I've added a single 300 watt panel with MPPT controller. If I could do over, I'd first add an arch, or an arch-like set of rails above the bimini. I'd then mount two panels, as large as would fit with a means to angle slightly fore and aft. We use our wind generator, but I installed a kill switch for when we don't want the noise. It needs new bearings but its a very tricky install, combined with the fact that simply getting the generator unhooked and down is a major hassle. I've had flexible solar in the past and the panels didn't last. Most contain very thin silicon wafers - very brittle and easily damaged. The idea that they can be stepped on is, in my opinion, marketing fluff. Maybe occasionally, but each step takes its toll.
I couldn’t agree more with everything you said. I tried to touch on all of that in the video , the noise from wind can be a nightmare but a kill switch is a great idea. How do you like the MPPT controller ?
I bought a Rich Solar 20 amp MPPT unit for less than $100 from Amazon. Its remarkably good - in fact I love it. I used to have a PMN unit, which I bought out of misunderstanding all the technology. Yes, that loses a lot of power (or doesn't harvest it well). The solar panel I got from emarine inc (Ft Lauderdale). It was $345 for a 300 watt panel. BTW, lab conditions for testing a solar panel are equivalent to noon, June 21st, with the sun directly overhead. So, it's possible to see that power only in the southern parts of the US, at that time, on that day.

Good job 👍🏻

Preference would be solar bulk plus small wind if wind generator doesn't shade panels.

Most panels are pretty good for declaring their peak output and it is achievable on a perfect day. You'll need a good MPTT charge controller. I have seen panels generating MORE than their rated wattage and I don't even live in the tropics. It's because reputable manufacturers use standardized lab test conditions based on the number of lumins the average solar wattage by square meter area. That's about 1kW. If you panel is clean, in good condition and you have a clear day with the panel pointed directly at (perpendicular) to the sun, it will hit it's rated wattage. Every little bit of inefficient use will lower that. Cheap PWM controller, you lose as much as 30%. Laying the panels on their back all day, lose another 30% at least. Shade them with sails, booms and even shadows from lines and you could lose another 30%. Suddenly your 1kW of panels on your yaught, even in the tropics is only generating a solar day average of maybe 200W. Avoiding those things is very difficult on a boat though.
Agree 100% that’s why I mentioned that reaching those numbers is realistically unlikely due to all the variables you just mentioned

You mention the caribbean vs.higher lat. What about the southern pacific ans southeast asia?
Just used those two areas as a example the same would apply anywhere that is cloudy vs sunny

Can you use both?
Yes
YOu could instal solar and wind turbine combined
wind....
