SOLAR Vs. WIND - How much power can you make? ELECTRICAL BOAT TECH (2 of 7) - Sailing Vessel Delos

ive watched a ton of these videos in no discernable order this is one of the most interesting ..much love to these dudes..Hey from PHX😎

Love it you guys are one of the reasons I'm getting into sailing. And I don't know anything about it. Any tips looking at a 34' sloop next month.

Thanks for the Link back to this video, Brian. Very interesting.

Super informative. Thanks for giving us the real info. I was surprised at the difference in battery efficiency from Lead/Acid to Lithium batteries, and their huge benefits in practical use.

super cool, thanks for the nformation

Keep these kind of TEC videos up !!

Cool!! Awesome info!!

Excellent: What is the solar panel sizes. I have wind and want to add solar. Thanks

nice for you guys

where can i get this mppt controller?

Just recently discovered your channel, and I'm going back through the older episodes! Love the content!

Video of 2 guys looking at a cell phone..... enjoy

Hi, your system is 24 V. How many equipment don't exist in 24 V ? How do you feed these "only" 12 V equipments ?

What solar panels are you using?

Hrrm interesting, you can also get DC air compressors for dive tanks and DC water makers, I wonder how this would effect the results.

Hi. Very detailed and technical video, and I appreciate that.

Obviously, your jump to lithium batteries was very successful. There are an array of lithium batteries types and manufacturers, all of which have a fairly wide margin of efficiency, or so I understand. And the technology is growing so fast that efficiency, capacity, and weight (as in decreasing) are increasing at an astounding rate per year. But that's another discussion, I suppose.

However, I would like to say that you didn't mention either weight or maintenance for your transition from lead-acid to lithium. Lead-acid maintenance is a bit more complicated than only draining to 30%...and I wonder if you had a scientific basis for that way of doing things. Also, the weight difference between lead-acid and lithium is astounding. A 50% reduction of weight...or more.

So...do you think battery weight reduction has affected the range of your vessel? Thought it isn't always so simple, in general, lighter vessels are more efficient.

Hi Guys. Thanks a for sharing your lives with us,. I sail a Dufour 39 around the Baleares Islands and the Costa Brava. I find your tips incredibly useful, and the way that Brian explains everything is really easy to understand. I have just listened to the episode on electricity consumption, wind and solar generators 12 to 24V which Brian and Brady put together and it has been enlightening, if you pardon the pun. Good luck wherever you are now.

3 years old and still relevant! Thanks Brian.

that was very good info i am about to upgrade my Cheoy lee 1984 boat to solar and that game a lot to digest THANK YOU

Love these videos.

Love you guy's long follower and big listener... Trying to keep up.

Great informative video. I'll be installing solar on my boat soon and think about similar setup with Li-Ion batt.

How stable is the 2 types of electrical together charging ?

a lot to learn from you Brian....

excellent info I like the comparisons which give people a good gauge on where to spend money with upgrades, I do wonder with your consumption of power you might need more batteries, also have thought about going electric for the engine with electric motor and regen when sailing

Brian, you are such a biscuit! I have learned so much from your channel - thank you! You are a legend!

I could be wrong but it seems to me that when looking at the wind generators, the terms of charging were in volts not watts as stated, would make better sense as a smaller sailboat could get all its power from wind generator and 25 watts just won't cut it

Thanks. Helped me troubleshoot my boat

This series is awesome. I'm just getting started outfitting my boat with solar as an electrical neophyte. I was going to have it done for me but the quotes I got for solar, lithium batteries, and a new charge controller were in the $15K range -- more than I wanted to spend. Educating myself so I can do it on my own will not only save a lot of $$$, but I'll know how to troubleshoot it and continue to upgrade it as time goes on (i.e. bimini solar, wind, hydro, etc.) or for the next boat.

There's some great info here Brian! Thanks for putting this series together. You may have covered this before and I just missed it, but how did you determine the amount of energy you would need to produce to keep Delos self-sufficient?

great video !!! i looked at my electric bill and it says i average 5.25 kwh a day but i use a 1hp aircon. does that mean the aircon was on most of the time? is your aircon 24v? thanks.

I probably missed it, but what about hydro?

You're on the right track!

But to be fair to the wind generators they will only excel at nite when there is no sun plus they will go into self regulation mode when the solar voltage is high my rutland produces about 1a per 20w mine is 12v ...mine is only 5meters off the ground on a caravan(rv)

Watching you as a freshly baked small sailboat owner with not much money is like watching an animated fairy tale. “Electric induction stove and oven” 😂
I enjoy it, thank you!

informative thankyou

You may increase the number of wind units.

show the electric diagrams

Thanks for the video.. Its helping me to self educate what direction I should take with my sailboat power generation project.

"you electricity bill will tell you how much electricity you use" what a dumb world we must live in!

we use 464 KWH on average per month at our house and its only 2 of us. My husband has a recording studio, so there's a lot of demand there. Wow.. The thing I'm realizing is watching these videos, its important to be aware of how our boat systems work and how our house systems work too and then trying to reduce our demand on the planet without compromising what is most important.

Thanks for the clear response on noisy wind generators.

Great vid!

The big problem with these small turbines is that they are just plain too small and in turbulent air. If you do the math, to get 150watts from 12 knots of windspeed, the turbine blades must be around 1,20 meters, assuming 30% turbine efficiency. however, a windturbine need to be 10 meter above anytime else within a 100 meter radius to get there.

So a single instabreeze i2000 ontop of the main mast or something, would generate a lot more. those can output an easy 750w at 20 knots, but i doubt it would actually last, swining around that hard on the mast.
