How To Build A Wind Turbine For A RV?

Yes, however your success with an RV wind turbine is dependent on your electricity needs and the weather. You’ll only get a fraction of the turbine’s capacity at lower wind speeds, which are already low for most people’s power needs.

Referring back to the graph above, a 10 knot (11 mph) wind produces just about 40 watts. That’s barely 10% of the maximum capacity!

You’ll also want to link your wind turbine to a battery system to store the energy for when you need it, because wind turbines only create power when the wind is blowing. You may be able to connect your turbine directly to your RV’s house batteries without using a charge controller in some circumstances. Many versions, however, incorporate one to safeguard your batteries and boost efficiency.

If you want to rely exclusively on your wind turbine, you’ll have to make some lifestyle adjustments to reduce your overall power consumption. Wind turbines are frequently used as a supplement to other charging sources, such as solar.

Is it possible to install a wind turbine on a recreational vehicle?

An RV wind turbine is a portable windmill that generates electricity by harnessing the power of the wind. This electricity can be used to power the electrical system of your RV, providing you with a long-term off-grid power source. They’re usually mounted on your RV’s roof, on a ladder, or on a freestanding pole.

What is the output of a 400 watt wind turbine?

HAWT 400 Watt The 400W turbine generates 50W at 3.6 m/s winds. The turbine will create 438 kwH per year if it runs 24 hours a day, 7 days a week. Because the national average electric tariff in the United States is $0.12/kWh, the turbine saves the owner $52 per year on electricity.

Is it possible to construct your own wind turbine?

Being started with home wind energy projects can be expensive if you buy a finished product, but if you’re handy and don’t mind scrounging for supplies and getting creative in the garage or backyard, you can make one of these DIY wind turbines for under $30 in materials.

Which is more efficient: a 12V or a 24V wind turbine?

12 volts, 24 volts, or 48 volts? I understand; it’s a common question. Our experience has shown that if you have one Deep Cycle battery, 12v is ideal, if you have two Deep Cycle batteries, 24v is best, and if you have four or more Deep Cycle batteries, our 48v Wind Turbines are best. Apart from the higher voltage, you’ll need a narrower gauge electric wire to connect the Turbine to your battery bank with our 48v Turbines.

When a 12v Wind Turbine and a 48v Wind Turbine are co-located 100 yards apart from your battery bank, the 48v Wind Turbine’s cable run will be a third of the cost of the 12v Wind Turbine’s cable run.

Higher voltage travels further over a smaller cable than, say, 12v over the same cable, as those of you who studied Physics in college may recall.

Is a battery required for a wind turbine?

Breeze backup: This structure, which is positioned at the base of a wind turbine, houses a battery for storing wind power. According to GE, you do not need to save 15 minutes of electricity to ensure 15 minutes of power output. A 625 kilowatt-hour battery would be required for a 2.5-megawatt turbine.

Wind turbines use what kind of battery?

A battery is defined as a device that turns chemical energy into electricity immediately. (Mubayed, Al-Sheikh, 2012) The lithium ion and lead acid batteries are the most commonly used today. Because they can store a high quantity of electricity in a tiny battery, lithium ion is primarily employed in portable gadgets such as a cell phone or laptop. However, because of the materials used and the complexity of the manufacturing process, they become prohibitively expensive when made at larger sizes. In these higher-power applications, the lead acid battery is typically used. It’s an important aspect of solar energy storage during night. These batteries are built into certain systems to ensure that they can provide electricity at all times. Batteries are used in most renewable energy systems today to perform two key functions. One is for the energy created to be stored, and the other is for the energy to be smoothed as it is produced. Wind and solar energy are examples of these implementations. Lead acid batteries, which are today considered obsolete technology, are nevertheless used in these systems. Longer-lasting batteries are currently being developed to replace the lead acid in these systems in order to save money.

Is it worthwhile to invest in small wind turbines?

Wind-generated electricity is nearly free after an initial investment. A tiny wind turbine can halve your costs. Renewable energy, space management, eco-friendliness, and sustainability are all advantages. Consistent electricity, animal risk, noise, and zoning limitations are all disadvantages.

Small wind turbines are a solid solution for anyone looking to save money, whether they live in the suburbs, live off the grid, or simply want to save money. They provide renewable energy that reduces your carbon footprint dramatically.

Let’s New York minute this topic with the pros and negatives, because we’re getting all Nancy Drew on little wind turbines.

Is it worthwhile to invest in rooftop wind turbines?

It is a renewable and sustainable energy source that will lower your carbon footprint from the moment it is installed. It helps you save money on your energy expenses. Wind electricity is virtually free once you’ve paid for your turbine. In the long run, even a tiny rooftop turbine can drastically cut electricity bills.

Is it possible for me to install a tiny wind turbine on my roof?

The United Kingdom is Europe’s windiest country. As a result, wind farms offer an excellent option for us to meet our energy needs while reducing carbon emissions. Wind power on a small scale can also be beneficial. A small turbine, on the other hand, must be precisely sited to be a cost-effective and low-carbon solution. Supporting and investing in large-scale wind power is the most effective alternative for most of us.

CAT has been employing wind power since the 1970s, experimenting with various types of turbines. You can see samples and displays around our tourist center, or take one of our courses to learn more.

How big does a wind turbine need to be?

The size of the rotor and the speed of the wind are two important aspects to consider while harnessing the wind.

When the diameter of a rotor is doubled, the swept area is quadrupled. This is because the radius square (A =r2) determines the area of a circle. As a result, a rotor with a diameter of 10 meters will capture 100 times the amount of wind as one with a diameter of one meter. As a result, very small turbines will not be able to capture much wind.

The cheapest turbines, which cost a few hundred pounds, are sufficient for charging a 12v battery in a boat or trailer. However, a far larger turbine would be required to achieve an output comparable to that of a household solar PV roof.

A rotor with a diameter of roughly 1 metre might generate a few hundred kilowatt-hours (kWh) each year. This is roughly equivalent to one solar panel. A rotor roughly 4 meters in diameter would be required to generate the same amount of electricity per year as a full solar roof array. This type of turbine would be impractical for most homes, but if you have enough land around your house, it might be viable.

How important is wind speed?

Doubling the wind speed will result in an eight-fold increase in power. This means that if you get half as much wind as predicted, you’ll only be able to harness one-eighth of the power. As a result, positioning a turbine in the most windy location is critical.

Many sites, especially on a small scale, are insufficiently windy. Even small turbines must be positioned on a high tower, away from buildings and trees, because wind speeds rise dramatically with height. Turbulence will be created as a result of these barriers, reducing power production and increasing wear and tear.

Where should I put a wind turbine?

A smooth hilltop with a clear open length, at least in the direction of the prevailing wind, is excellent. Open stretches like this are rare in towns and villages, which is why they’re usually horrible places to visit.

We strongly advise spending a few hundred pounds on reliable measuring equipment such as a mast and data recorder before investing thousands of pounds in a wind turbine. Be cautious of solely depending on an internet database that provides wind speeds for a specific postcode or map reference. These do not take into account the effects of local conditions on a tiny turbine.

Can I put a wind turbine on my roof?

We strongly advise avoiding installing wind turbines on rooftops or buildings since they will only receive weak, erratic breezes. Building-mounted turbines have been found to function badly in field trials, providing only a small percentage of the energy they would produce if correctly sited.

Obviously, a non-spinning turbine will not save you money or reduce carbon emissions. Turbines can also reverberate in the wind and cause vibrations, which can damage the building’s construction.

How much do small wind turbines cost?

A turbine, tower, and installation might cost anywhere from 2,500 to 6,000 dollars per rated kilowatt (kW). It’s crucial to consider the tower and other system components when determining installation expenses.

Turbines are designed to operate with little maintenance, however some moving parts may need to be changed over the course of their 20-year lifespan. If an inverter is required, it will most likely need to be replaced over the turbine’s lifetime.

How much will it pay back?

Based on current electricity prices, whatever you can use directly will save you around 16p per kWh. However, keep in mind that this pricing is from before the current electrical market turmoil, which will surely change things.

You can now export to the grid instead of getting paid back under the Smart Export Guarantee (SEG) plan for what you can’t utilize. You’ll need a smart meter that can measure exported electricity to be eligible for SEG incentives (which many first generation smart meters cannot do).

You should search around and compare the prices for the electricity you export. Some firms may charge more than 5 pence per kWh for SEG, while others may charge as little as 1 penny per kWh. Solar Energy UK has prepared a tariff comparison table. According to them, a reasonable price is between 5 and 6 pence per kWh. This is similar to the wholesale market pricing that major generators receive for selling electricity. The current increase in wholesale energy prices will almost certainly result in adjustments.

Community Power

Wind turbines on a large scale may capture even stronger winds on hilltops distant from towns. The greatest option for most of us to gain from wind power is to invest in a large community-owned wind turbine.

Is it possible to use a car alternator to power a wind turbine?

If you’re new to the idea of making a wind generator out of repurposed parts, you’ve undoubtedly asked yourself a few questions like these:

  • Why are automobile alternators suitable for wind energy?
  • What adjustments are required to convert an automobile alternator into a functional wind generator?
  • What is it about Delco-style alternators that makes them so popular?
  • Which WindyNation blades work best with Delco-style PMA wind generators?

Perhaps we asked that last question ourselves! In any case, if you’ve ever wondered about repurposing automobile alternators, now’s your chance to learn everything you need to know.

Wind power enthusiasts are increasingly common around the world, taking advantage of excess supplies of alternators or motors that were originally intended for purposes other than generating electricity from the wind. Fisher & Paykel washing machine motors are quite popular in Australia and New Zealand, as these machines utilise big permanent magnet motors. Ametek, Inc. is best known in North America for their tape drive motors, which were once readily available and immensely popular for constructing wind generators.

However, when it comes to DIY modest wind power, the Delco brand of permanent magnet alternators is likely the most popular.

Why are Delco-style Alternators So Popular?

The Delco moniker is derived from Dayton Engineering Laboratories Co, a long-time supplier to General Motors. Delco had a long and illustrious history, which included the invention of the first practical battery ignition system. Hundreds of key components for American-made autos were manufactured by the enterprise, which was absorbed into a variety of larger mega-corporations. GM still uses the Delco brand name, especially for its ACDelco components division, but the corporation has come a long way since its early pioneering days.

Since the early 1980s, the American auto industry has had a lot of excess production capacity, which has often gone into generating a lot of components that don’t always wind up in automobiles. Even though these alternators didn’t find a place under a hood, they found a way to be useful. Delco has experienced a rebirth among wind power aficionados. For usage in small wind generators, repurposed vehicle alternators have become exceedingly popular and relatively cost-effective.

Most ACDelco generators that are sold specifically for use as a wind generator have been repurposed or rebuilt. The reason for this is that when a Delco automobile alternator is employed in a wind turbine, it operates under different conditions than a permanent magnet alternator.

What Modifications are Necessary?

The stator of an automobile alternator is wound to function at extremely high RPMs, owing to the alternator’s luxury of being turned by a powerful, high-rpm engine. The operating rpm of a Delco vehicle alternator is around three times that of the crankshaft of the car engine. The crankshaft of a car rotates between 1000 and 4000 revolutions per minute. As a result, a Delco automobile alternator is built to provide adequate charging voltage and amperage at 3000-12000 rpm.

In 25 mph wind, a modest wind turbine with a rotor diameter of about 60 inches may reach 850 revolutions per minute! The threshold for a normal Delco automobile alternator to even begin charging a 12 volt battery bank is 850 rpm!

When using a Delco automobile alternator as a wind generator, it is imperative that the alternator be modified to run at low RPMs. This is achieved by two complex modifications:

  • The stator windings on a Delco vehicle alternator are replaced with a stator with more turns of lower gauge wire.
  • On the rotor, high-powered Neodymium magnets are used, which produce more power than conventional magnets.

Where Can I Buy Quality Delco Alternators for Wind Turbines?

WindBlue manufactures high-quality Delco Permanent Magnet Alternators (PMAs), and they are ethical and transparent in their assessment and presentation of the PMAs’ expected power output. They generally achieve this by displaying a Power Curve that shows the output of their alternators under load. This is in contrast to some other re-sellers of modified Delco PMAs that only show open-circuit voltage readings, which are essentially useless indicators of a PMA’s output.

Have Reasonable Expectations

When it comes to Delco alternators, it’s critical to have realistic expectations for the amount of power these devices will provide. In other words, you shouldn’t anticipate a Delco PMA to produce a power production miracle because the amount of power a wind generator or alternator can produce scales with:

  • The maximum amount of copper that can be crammed into a stator.
  • The number and size of powerful neodymium magnets that can be used on the rotor.

Because a Delco automobile alternator is about the size of a cantaloupe fruit, the amount of copper and magnets it can hold is limited.

A automobile alternator, maybe more importantly, was designed to be installed under the hood of a vehicle. This is not meant to be a criticism of their quality or even their suitability as wind generators. It is a basic reality that the specs for a car alternator and a wind generator are vastly different. A car alternator, for example, will not be weather-proof because it is normally protected from rain and mist because it is located under the hood. Second, the stator must be rewound in order to provide a voltage adequate for battery charging, as we’ve just mentioned. Third, because it is turned by the automobile’s engine, which may produce at least 100 horsepower (76000 Watts! ), a car alternator does not need to be particularly efficient at generating energy.

Great Way to Learn How to Build a Wind Generator

Nonetheless, we are heartened by the thousands of people who have learned the foundations of wind power via Delco PMAs and are now using them to generate significant amounts of electricity.

We’ve put WindyNation blades through their paces on a variety of WindBlue alternators, and we prepared this section to serve as a resource for consumers considering WindyNation aluminum wind turbine blades in conjunction with a WindBlue alternator.

On the WindBlue 540 and 520 series PMAs, we tested numerous sets of our blades. The load for all of the experiments was a 12 volt battery bank.

Three of our 28-inch HyperSpin blades performed admirably with the WindBlue 540. In 11-13 mph winds, we measured 2-4 Amps of power into a 12 volt battery bank. We measured roughly 10 amps of output into a 12 volt battery bank in very high gusts (20-25 mph). The 540 is ideally suited for the HyperSpins. The 540 PMA is wound for high voltages at low RPMs, allowing it to charge in low to medium winds. As a result, the unit’s Amperage output suffers slightly.

The WindBlue 520 worked best with the 5-blade HyperSpin set, which offers a good balance of torque and speed. This alternator produces more amps than the 540, but it takes a steady 9 mph wind to start charging a 12-Volt battery. The alternator was able to produce 3-5 amps in a 12 mph wind. The 540 produced 12-17 amps in 20-25 mph wind, which is a reasonable amount of power for a little PMA.

Overall, we were impressed with WindBlue’s alternator’s performance. If you’re dead set on employing a Delco for your wind turbine project, we recommend the WindBlue. If you’re looking for something a little more powerful, we recommend the Windtura 500 PMA.

Anyone can see the appeal of modified Delco automobile alternators for do-it-yourself wind power: LOW COST.

Thousands of DIYers utilize these devices to build modest, low-cost wind turbines all around the world. It’s critical to have realistic expectations regarding how much power a Delco-style alternator will produce when acquiring one. Furthermore, because the Delco alternator must be “rebuilt” for use in a wind turbine, it is critical that you obtain a Delco alternator from a reliable and honest company. A Delco car alternator that has been adjusted by an inexperienced person or a company that takes shortcuts will have poor performance, cogging, and will most likely fail on you.
