Hi, thank you for this video. I'm completely off grid, with a 5.4 kw solar system and 10kw Pylontech 48 volt battery system living in Portugal. Even in the winter this system is sufficient for our needs. But I would like to switch to a AC inverter heating system for in the winter instead of a fire place. That means I need some more energy and would like to combine with a small wind turbine. I have a free standing house and the wind is not blocked from any direction as I don't have neighbors. As we do have the fires in the summer all the big trees burned down in 2022 and we have very strong wind. Can you recommend me a small wind turbine? I can't figure it out by myself. Thanks a lot 🙏
true. I did a couple of research few years ago on youtube on multiple videos/channels. My conclusion is one needs an open field/farm for tall tower before starting any wind turbine for residential.
These test were done on a favorable wind direction. Where I stay, the wind direction constantly changes. I've watched other peoples vertical wind turbines and evertime the wind changes, the turbine loses momentum. Which is why I think that a horizontal wind turbine would be a better choice.
Thank you. I live in Tehachapi California, basically the birth place of windmills. I’m off grid with just solar.. now. I had a Southwest Wind Whisper 3.2k turbine that was eaten alive with our constant 20 mph/32.2 kph wind here. It would sound like a helicopter and friends were scared. All the large commercial wind generators around here have transmissions and a great brake system. I have yet to see something like this for residential use. Any thoughts on what might last here where I am? I don’t see a lot of RU-vid channels that actually pull units a part and check out the build quality. TIA.
Very interesting information, and useful. Have you seen the roof ridge turbines, if so what are your thoughts. ? The pitch of the roof funnels more wind up to the ridge, and they blend in with town architecture more suitable Given that a roof must have some sort of ridge to cap the slates or tiles if the ridge turbine is installed do you think it worthwhile to build as standard.
Best thing is to beult one your self You only need blades and alternator from a car. Stick it up high and it works. All the other stuf are crap . You do need 1000 rpm a minute so you need to calculate the settings form gears . Best alternator are the japans small cars . Those are small and turn easy .
Hey I love your work and have to ask, have you tried out the Liam F1 wind turbine yet? Or any with fibonacci design? Would love to hear peoples independent thoughts that have used it in person
Ugh im so lost, i got a bunch of components, i want to set up an off grid system but i have no clue what im doing, this video explained a lot thank you
È un piacere seguirti sul tuo canale, recentemente mi sono iscritto. Volevo comprare una turbina eolica per supportare il mio impianto fotovoltaico durante i momenti di scarsa luce solare o di notte. Dopo aver seguito i tuoi suggerimenti, mi sento confuso e non so più quale opzione prendere in considerazione. Faccio presente che la pala dovrebbe essere posizionata sul mio palazzo, dove di solito il vento soffia a una velocità compresa tra i 4 e i 10 metri al secondo. È fondamentale che sia abbastanza silenziosa. Spero che queste informazioni ti siano utili per fare la scelta giusta. Grazie. It's a pleasure to follow you on your channel, I recently subscribed. I wanted to buy a wind turbine to support my photovoltaic system during times of low sunlight or at night. After following your suggestions, I feel confused and no longer know which option to consider. I would like to point out that the blade should be positioned on my building, where the wind usually blows at a speed between 4 and 10 meters per second. It is essential that it is quiet enough. I hope this information helps you make the right choice. Thank you.
Wind Turbines are Bullshit Solar panels have there short comings. A 5kva stand alone system is not cheap. Here in Australia when you buy a mains Solar power system/feeds back into the grid/ you really don't own the system. You really are only hiring it without knowing
I inherited a 3-story residential building with about 6 apartments that host small families or single individuals. The building is located near the top of an elevation, and I've experienced good wind flow when on top of it, but haven't measured it carefully, yet. My question is about transmitting the output of an equipment that I install on a tower over the roof (not necessarily too high, as the 3rd floor roof would grant a good altitude by itself), to the renters, so that they pay for the electricity, even though in a mixed system with the regular electricity provider in our region, a town in the state of Minas Gerais, Brazil. Is there a way of measuring the individual consumption for each apartment? My idea is to charge them with a discount (20% or 25%) over the regular price of the electricity provider company. I wonder whether that would be feasible.
most of this just wastes time repeating the obvious that this audience already knows. If i were to translate the script to BS, what percentage would be BS? Do it yourself.
The video seems to target more the "new buyers" rather professional or seasoned veterans. Like everything, it may be obvious to an expert, but it can be useful to a newbie. And remember that all experts started as newbies
Oh thanks, about the costs, kWh and invest. With 19 Cent or for Thai Baht (6.27 Baht) I have to beet 4 Baht (first 150 kWh) to 7 Baht for over 400 kWh. 10 Meter plot available from old WiFi, but no Wind or less than 2 m/s most ... sadly. But I might have to measure some days myself to sure. So far the Solar have to make it ... Invest 6.400 US$ and paid of with savings End of November this year. Wind seam to be more expensive ...
good morning just watching your video i have a tesup 7kw hera wind turbine can you help i am trying to get some dater about them as the one i have do,s not spin and i am not sure why
Thankful for finding your channel. Our small group of coconut farmers is contemplating on a solar and wind dryer to minimise the use of the traditional copra making. Any advice? Thank you!
Main direction south-west. Which is the tree side (50meter away). Average speed is 4.5 m/s (if I understand the atlas correctly). So that closes the book on getting a wind turbine.
What I found is that the pole is just as expensive as the turbine which pushes up the price a lot. I found one all-in price for a 5kW darius for 25k Eur in NL
I liked the explanation of small wind turbines. It reinforces my longstanding belief that efficiency in your building envelope and heating and cooling systems as well as appliances are the best ROI. If you build a home that requires only 20% of the energy to heat and cool through insulation and passive principles and select the most efficient appliances and use mini splits which can have SEER ratings over 30 and HSPF ratings over 14 and for hot water system use a heat pump unit. The cost of doing this will less than a solar or wind system.
I once saw a bladeless wind turbine advertisement in the RU-vid since I've been researching about solar panels and wind turbine recently do you think this bladeless wind turbine is interesting?
Fine analysis of current market; do consider the general pros are that wind balls can be arrayed denser with (unmeasured) benefit and accessible to the ground in comparison to wind towers. Imagine if I told you my 20%-40% less efficient design can be placed 10x more: thats 6-8x the output of the single more efficient model and would change the general efficiency understanding, but again less of a single buyer perspective and more general analysis comparison importance. (I dont know the specific array density of these models just general important analysis consideration with windmills. 🐧🐉)
An honest answer: a lot of claims are made in the field of small wind power. The decisive factor is evidence in the form of independent test results. I primarily deal with wind turbines that have proven themselves in practice.
Very helpful video thanks so much. I own a farm in a rural area (technically "on grid" but in between two small towns, ie with no other buildings nearby). According to the local meteorology station in the nearest town, the general area receives on avg 3m/s wind - that said, and in my personal experience, the exact spot where farm is the wind is significantly stronger, at least 2x as strong; again, my estimation. Important to point out that there are already several state owned large wind turbines scattered around the area. My farm is on a hill with an elevation from 130 to 90 meters above sea level with no obstruction, so my question is: would a small turbine still require that 10 meter high position? I would like to keep everything discreet an in line with the surrounding landscape. Thanks again.
just set it towards the west, the predominant source of wind, let me tell you you dont want to take any of the east wind, theres only a limited amount of precipitation left in the future, healthy and not, and the people are doing really badly - just set it to the west and on the ground in a shelter, wind tunnel, conservation
yeah a smaller one, not a 5 meter one, i cant believe youre trying to sell 5m rotor turbines on youtube, should barely be selling 2m 1s, crazy, or maybe i can believe it if you are a common community demon taking advantage of people at any opportunity: NOISE POLLUTION -- i'll tell you i put one on the ground on a stump and it does great, not hooked up to a generator though, and there was a vicious dog around one day looking to get at me after i used a chainsaw for hours in my yard, it was sent to bite me and then it investigated the running turbine and it might have gotten hit, which would be devastating if true, and protect me from its vicious bite, and i havent seen it again - so don't try and put your hand into a running wind turbine - can't be sure if you really know it or not but i'm not too worried
I am an independent expert and author focused on small wind turbines. I do not sell wind turbines. Here you can find honest information on the topic. That's why I say clearly when a small wind turbine makes no sense. For example, if you have a location with too little wind.
at a good location you don't need to put it on a pedestal but you could put it in a wind tunnel to conserve nature and diminish the awful noise POLLUTION - you want to eventually put them in small windtunnels, or large, and conserve the wind to stop killing the planet
too loud for residential neighborhood, too many blunders you could end up in prison - i have a smaller one behind a shed on a round from a tree, FAR TOO LOUD to be unprotected, i can't believe you would let people put it up near their home without protecting them from the atrocious noise, or maybe i could imagine you do it as a common community demon, its like thats all thats out there, they'll just get the turbine to put it up to bother people - cops won't save you and won't help, false friends, its the thought that counts
The noise level depends on the design of the rotor blades. Rotor blades that are very quiet have been specially developed for sailing ships. They have to be, otherwise people in the immediate vicinity would not accept the wind turbine. But there are big differences in noise levels. There is often too little wind in residential areas, so you have to check the location particularly carefully beforehand.
we're looking for ways to no longer need the rest of humanity because of trans humanism, baby sacrifice, and tyranny. we would like to go to space and cure diseases, but instead we're all running into the woods to get away from each other. good job humans.
*All practical tests show that small wind turbines hardly generate any electricity. And only at costs above 1$/kWh!* There is hardly any wind near the ground. And it is also very gusty, which extremely reduces the lifetime of the turbines. If you don't have to be self-sufficient in electricity, you shouldn´t use small wind turbine, but install solar panels. *With solar panels, you can reliably generate electricity for about 3-10 cents/kWh over a period of 25 years!*
There are many suitable locations for small wind turbines. However, these are not in residential areas, but in the countryside. The decisive factor is the free flow from the main wind direction. More on this here: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-Jswyg_z725A.html
@@WindSunWisdom The MOST DICISIVE factor: Electricity yield increases with the third power of the wind speed. 100% more wind = 800% more electricity. And close to ground there is hardly any wind - and extremely gusty. Which usually greatly reduces the service life of the wind turbine.
Great information, however, the final thought: "A small wind turbine only makes sense in a windy location" doesn't consider the long term cost of burning fossil fuels on our climate (that most grid energy comes from), nor the fact that there are some places on earth where there is no power grid, where travel and hauling in fossil fuels is very expensive, and where there's not much else to derive energy from besides slow winds. In that case, even though a small turbine would be quite expensive relative to other locations, it still may be the best option for that particular low-wind location.
At a location with very little wind, so little electricity is often generated that you do not have a positive ecological balance with the wind turbine. In this case, a small wind turbine makes no ecological sense.
99 percent of these small wind turbines are useless gadgets sold by door-to-door salesmen to gullible homeowners. Our local utility has hundreds of these things hooked up, and none of them come even close to paying for themselves. The rule for determining the viability of wind is this…. If you are standing three feet from another person, and you need to yell at them in order to be heard, you have enough wind to be viable wind power. There are places like that, but not many residential neighborhoods are built in those places.
I agree with you that there are many dubious suppliers, especially when it comes to home wind turbines. They want to sell you a wind turbine for a residential area where there is far too little wind.
Solar and wind complement each other very well in many climate zones. In this case, the battery does not have to be large. But you definitely need a location with a lot of wind, which you must check beforehand.
