Noise Issues: Small wind turbine noise is only slightly above wind noise. (Click On Video Tab Above) You may be able to pick out the sound of a hybrid wind turbine if you strain to listen but most people would not find it objectionable. However, if there is any doubt if your wind turbine will disturb your neighbor, be a good neighbor and have a conversation with your the family living next door in advance.

Before going solar, it is advisable to perform thorough assessment of your home insulation in order to improve heating efficiency and minimize all possible losses. This is very important because after minimizing heat loss in your home, you can actually install smaller solar system and get the same result as with the twice bigger heating system. To size your system efficiently and learn more check out my post on how to improve thermal efficiency of your home with bubble wrap insulation on windows.


Every turbine should include an owner's manual or operations manual to provide the consumer with scheduled and unscheduled maintenance information as well as other unique product information. Scheduled maintenance guidelines should be followed. If you do not have the expertise to maintain the machine, ask whether your installer provides a service and maintenance program.

Each time it’s accompanied by some type of announcement about how great solar is, and how they are building or have a solar farm, and they love solar. The next paragraph though, talks about how if you have solar panels, they are charging you more, or somehow increasing the costs. When I started getting quotes, payback was calculated at 6.3 years. Now, 4 years later, I’m looking at about 10.5 years . . . from today. Functionally, they have more than doubled my costs.

How high is your tower? Hands down, the biggest mistake a homeowner can make with a small wind turbine is putting the turbine on too short of a tower. Like solar in the full sun with no shade, any renewable energy source must have good access to the fuel that drives the electricity. There is nearly 100% more power available in 10 MPH winds than 8 MPH winds.

Because residential solar energy systems are a big investment, you’ll want the system installed correctly and to full functionality. With this type of investment, it seems more effective to rely on the professionals who do these types of installations daily. Most residential solar systems can be installed in about two days. And solar consultants will monitor your energy usage and recommend the best system for your needs and the best placement to optimize solar energy conversion.
I found that the best way to connect between two cells was to use hot glue and some conductive mesh. The mesh is good since it allows light to come through it, and we all love glue guns. So all you need to do is glue the mesh onto the solar cell surface. Its always better to have a longer strip of mesh on the surface, with a big enough shared surface space between the two. Always check with a multimeter that there is connectivity, and that there is voltage coming through. Its a bummer later to try and figure out where the problem is.

You might love the idea of producing alternative energy in your home. Fine, technology has indeed brought us different solutions to easily make power right anywhere. Setting up residential wind turbine kits in your home or worksite is surely one of the coolest ways to contribute a share of green energy to your daily needs. Thus, you become a part of the world’s strive to end huge reliance on the depleting traditional sources of power.
While I think on a personal level, distributed solar/storage is great, it just doesn’t seem to scale on a system level, since there is a lot of economies of scale in terms of cost (compare $1/W utility PV vs. $2-3/W rooftop PV), and a lot of benefits from geographical diversity, both in terms of load (your load is way more spikey than CO’s average load), and renewables (while your solar array might be doing bad during a cloudy winter day, the wind could be howling at a wind farm in Iowa or it could be sunny in New Mexico). If we really want to go 100% carbon free, we will need all the geographical diversity and economies of scale that we can. A bunch of people with rooftop solar + a battery won’t cut it sadly.

Solar panels are no longer just for hippies. If you’re just as interested in saving money as you are in saving the planet, solar panels can help you do that. Their price has come down, their effectiveness has gone up, and Congress extended a 30 percent federal tax credit for installing them until the end of 2019. All of this means solar panels can now pay for themselves in as little as five years, depending where you live. But are they right for your particular home? That’s a question that raises more questions. Ask yourself these things before making a decision.
When contemplating installing a residential wind turbine on your property, it is important to know how this energy saving resource works. A typical wind power system is made of a wind tower and a turbine with multiple blades. The wind spins the blades, converting the wind energy into electricity. The height of the wind tower varies depending on the location of your house. The wind turbine blades collect the wind energy that is then converted to an electrical current that is compatible with your home. In a typical residential application, electrical power is provided by the wind turbine and the local utility. In essence, you can harness free energy from the wind, and use this energy to supplement the energy you are currently purchasing from other utilities.
Solar panel mechanical characteristics such as dimensions, frame profile, and static load rating, as well as grounding and mounting locations will need to be understood when designing your home solar grid tied or off-grid system. Frame and back sheet color may also come into play for residential DIY customers. Black frame solar panels are very popular because the aesthetics of the panel blend very well with many roof applications.

If you do have a suitably sunlit rooftop to work with, Weissman says, make sure it’s in good shape structurally. Solar installations these days can come with warranties for 20 or 25 years. If your roof will need a renovation a few years down the road, it’ll be easier to take care of that before the array goes up. That way, you won’t have to pay in extra time and money to disconnect your panels during the roof renovation and put them up again afterwards. While you’re at it, make sure you won’t run afoul of any homeowners’ association covenants that ban rooftop solar for aesthetic reasons.
A new commercial or industrial wind turbine ought to require little or no maintenance. Manufacturers construct twenty-first-century wind turbine blades from composite materials so that they will not corrode or require replacement; new blades ought to withstand even torturous conditions with little or no routine care. Similarly, reliable wind turbine builders fashion the latest generation of nacelles from rust proof or rust resistant alloys and powder coat the units for maximum durability; the units seal tightly, protecting the working parts inside. And, as with most major machinery, an ordinary wind turbine user will find no user-serviceable parts inside the nacelle. If the unit fails, it will require professional service. Even with all these features designed and guaranteed to keep your wind turbine running smoothly and reliably, the system still requires routine maintenance.
Beaufort scale—A scale of wind forces, described by name and range of velocity, and classified from force 0 to 12, with an extension to 17. The initial (1805) Francis Beaufort wind force scale of 13 classes (0 to 12) did not reference wind speed numbers but related qualitative wind conditions to effects on the sails of a frigate, then the main ship of the Royal Navy, from "just sufficient to give steerage" to "that which no canvas sails could withstand." Although the Beaufort scale has little use in site assessments, a system of tree flagging observations has been used to estimate prevailing wind directions and levels on the scale over time.
“I don’t live in Colorado. How much juice will I get out of it where I live?” This part is fun: The National Renewable Energy Lab runs a great, free calculator called PVWatts that does it all for you: factoring in average weather and solar angles in your area, even allowing you to specify solar panels placed at any crazy angle you like. (In other words, your house doesn’t have to have a perfect South-facing roof).
Since the energy output to the loads must be balanced by the energy input from your solar panels and wind turbine, we need to calculate your daily charge requirement in amp hours as that number will come in handy later. Take your total daily watt hours x 20% (rule of thumb) to account for losses in inverter, circuits and wire transfer. Now divide by the system voltage you chose based on the previous section and write this number down. This is the charge in amp hours your solar panels will have to provide each day to meet your load requirements you have set. Example 5,000 watts daily load total X 20% = 6,000 watts / 48 volt system = 125 amp hours that will need to be generated. Example #2, 5,000 watts daily load total X 20% = 6,000 watts / 24 volt system = 250 amp hours that will need to be generated.
How, you ask?? As it happens, our garage roof is by far the sunniest part of our property, so that’s where we put the panels. You can look for “holes” in the canopy too – a tool called the Solar Pathfinder is good for this purpose. Or you can go hardcore Mustachian: take pictures of the south-facing part of your house at different times of day, at different times of year, and then chart the pictures out to see where the sun shines reliably :)
Permitting—The process of obtaining legal permission to build a project, potentially from a number of government agencies, but primarily from the local building department (i.e., the city, county, or state). During this process, a set of project plans is submitted for review to assure that the project meets local requirements for safety, sound, aesthetics, setbacks, engineering, and completeness. The permitting agency typically inspects the project at various milestones for adherence to the plans and building safety standards.
With our solar panels installed, we were waiting for the outside temperature to drop below -3°C/26°F, and surprisingly solar collector was already supplying the room with 3 m3/min (3 cubic meters per minute) of warm air. At the same time we have switched to more powerful fan than the one for testing. Hot air temperature went up to +72°C/162°F (measured with digital thermometer). To calculate total energy production of the furnace, we took into calculation the air flow and average air temperature on output. Calculated power which DIY solar panels produced, was approximately 1950 W (watts) which is almost 3 HP (3 horsepowers)!!!
Also, HQST sends you a little pamphlet with these panels, offering you a free 2W/6V solar panel, in return for you leaving a review. While this is the reason I am writing this review (I usually don't bother leaving reviews for anything), it in no way influenced my review. These panels are well constructed and very efficient, I don't think you can beat them for the price.
In any generator whether it be a re manufactured delco permanent magnet alternator, our white lightning radial or even the larger axial flux designs different wire gauges can be used and are used for different reason for a given application. It is important also to understand that generally speaking when you are looking at a permanent magnet alternator for sale on our site ebay youtube Amazon ect when you see a voltage advertised such as frequently 12, 24, and 48 models this usually does not mean that there is some sort of internal regulator which limits the output voltage of the generator or pma to an adequate charging voltage level for an application This is one of the biggest mistake we see do it yourselfers make when selecting a generator. Typically sellers and manufacturers rate a permanent magnet alternator as for instance 12 volt when the RPM range of the generator is sufficient to reach Cut in Voltage to charge a given battery bank. Windmill, wind generators, wind chargers, or residential wind turbine kits terms we often see used interchangeably are trying to tell you that in a direct drive application with a particular blade set that they would use a particular generator for an application. So what’s the difference? Any style generator has a capacity “slots” or area that a winding can fit in. This will be unique to the particular generator. It is important to understand that within the working area different wire gauges can be used. In the area of the generator windings more “ turns” wraps or whatever terminology you prefer can fit in a given area with finer wire that with thicker wire as a matter of what will physically fit in a given stator coil, wrap , winding and or slot “again whatever terminology is appropriate for the given alternator.

In addition to zoning issues, your neighbors might object to a wind turbine that blocks their view, or they might be concerned about the sound it produces. Most zoning and aesthetic concerns can be addressed by supplying objective data. For example, a typical 2-kilowatt wind turbine operates at a noise level of approximately 55 dB 50 feet away from the hub of the turbine.[10] At that level, the sound of the wind turbine can be picked out of surrounding noise if a conscious effort is made to hear it.
Equipped with a 3-phase External Rectifier pigtail. This small black connector on the back of the unit allows you to run less costly 3-conductor wire to your battery location instead of large heavy battery cables in addition to lessening the voltage loss you get with DC power. Once at the battery location the 3-phase power is fed into the included Charge Controller and is converted to DC for connection to the battery.
