1. How can I use WindStax?
- – Supplemental power for residential or commercial use. Some customers use WindStax to provide power to specific buildings or “zones” within buildings. Free electricity is the goal. We call these “microgrids.”
- – Put your game room or home office on a separate circuit. That room becomes the “green energy zone.”
- – Storage garages, barns, and outbuildings where power is only needed occasionally are great for WindStax.
- – Common area lighting in subdivisions or other multi tenant buildings. Surprise and impress your tenants when you give them a green energy credit for their common area maintenance expenses. Keep the tax credits for the holiday party and accumulate valuable Renewable Energy Credits for the lift of the system.
- – Uninterrupted Power System back up (UPS). WindStax can provide electricity seamlessly if you lose utility power. When connected to the utility current, WindStax senses a loss in house current and automatically switches to battery power. How fast? How about 10 milliseconds fast. You have power for hours or days depending on the application. Ingeniously, this setup also uses house current to top off the WindStax batteries if needed.
- – WindStax provides power right now. Like a standby generator for emergencies but without the fuss, noise, uncertainty and expense of a gas or diesel generator:
Unlike a standby generator, WindStax stores power at all times, ready in an instant in case of a power failure. In addition, they do not get water in the fuel, a frozen starter, dead batteries, a sticky choke, clogged filters, or find 100 other reasons not to start when they are needed the most.
- – WindStax power is pure sine wave electricity capable of running your most sensitive electronics. That power is cleaner than typical house current and far more stable than electricity produced by combustion generators.
- – Off-grid and remote power:
- – Cabins, trailers and, barns,
- – Remote irrigation systems; feed systems, monitoring and alarm systems. Golf courses love WindStax
- – Natural gas and other pipeline distribution systems requiring cathodic protection or remote monitoring.
- – Intermittent exterior lighting in parks and campgrounds.
- – Green energy charging or comfort stations on trails and other remote recreational facilities.
- – Fairs, festivals, and special events should consider our mobile unit. It’s hard to be modest when you a draw a crowd. WindStax are a great way to promote your event while showing off your commitment to the environment. Who wants to hear and smell a noisy generator at a concert or outdoor event?
2. Can WindStax be used to net meter? Net metering is selling excess electricity back to the utility company.
- – WindStax can be used for net metering. However, net metering is a complex and expensive undertaking regardless of your source of alternative energy. Each state and utility has different rules, regulations, and limitations on net metering.
- – Despite what competitors might tell you, net metering rarely makes economic sense. Utilities like to sell electricity – not buy it from their customers. We can talk you through a better and more cost-effective method of saving money by generating and storing electricity to use where and when you need it.
- – The WindStax approach to interconnect is different. We pioneered microgrids. In effect, our customers produce and store their own electricity and use the utility as a backup to green energy. Your wind power system functions as the primary source of electricity. If consumption exceeds the battery capacity and the ability for the wind to keep up with demand, our smart control system switches back to grid power. The utility takes over while the batteries recharge. Once they are charged, the system switches back to green energy. In that way, you are consuming 100% of the green energy your are capturing. It’s an elegant alternative to the messiness of net metering.
- – WindStax systems also have an option to start and run a natural gas generator should the batteries deplete faster than you consume power, leaving the utility power as a third and final resort. We can design and install this system including a matched generator that can get you all the way off the grid. Now that is energy independence.
- – If your alternative energy is net metered your home or business goes dark. With our microgrid solution, when utility power is lost, your power stays on because you enjoy the benefits of a powerful uninterrupted power source.
- – If you are interested in net metering all of our units can net meter in lieu of battery storage. If you have the land, resources, and electricity demand to take net metering to a higher level of generation, see the following FAQ.
3. Can WindStax be used for a wind farm?
- – Yes, an array of WindStax would make a nice wind farm under certain conditions.
- – Today’s traditional wind farms consume approximately 10 acres of land per megawatt and come with a host of challenges for developers. Dozens of large WindStax can fit within that same footprint avoiding many of those challenges.
- – In fact, recent research shows that vertical axis wind turbines placed together in a close array can yield ten times the energy as when more widely spaced. Sandia Lab researchers think the VAWT design can be scaled to 10 megawatts more easily than traditional horizontal axis turbines.
- – WindStax are great for community-wide microgrids. Microgrids are modern, small-scale versions of the centralized electricity system. Think of a subdivision or multi-tenant building. Talk to one of our experts about community microgrids.
4. How much power does WindStax generate?
- – WindStax produces and begins to store electricity at very low wind speeds. As the wind increases, the amount of electricity generated increases. Just like all wind turbines, factors like elevation above sea level, temperature, wind density, and barometric pressure effect power output.
- – Unlike all wind turbines, WindStax makes power for its on board power management system and stores that power to be used when it is needed. Clean, reliable power comes from the batteries and inverters – not directly from the turbine generator.
- – Unfortunately, there is no standard reference to compare one turbine to another. This is particularly true of vertical axis turbines. The rated power system used on all wind turbines can be confusing and sometimes misleading. Rated power is often based on projected output at unrealistically high wind speed of 27 mph. A better metric is Annual Energy Output (AEO), sometimes called Annual Specific Yield.
For the sake of comparison, WindStax AEO at 12.3 mph average wind speed is approximately:
- WindStax 20 – 5,668 kWh/yr
- WindStax 40 – 11,336 kWh/yr
5. The better question about power: How much usable electricity does WindStax produce?
- – WindStax 20 and 40 base units come with 120Vac/60Hz 1800 watt continuous/3600 watt surge rated inverters. Larger units up to 17,600 watts are available with multiple units in clusters. That is pure sine wave power by the way, cleaner than many public utilities. We have 120/240Vac/60Hz single phase setups. Some 230V/50Hz international voltage options are available.
- – Every WindStax unit accept more wind turbines or add solar power, making your WindStax a hybrid wind/solar unit. Choosing the hybrid electronics option gives you a powerful way to aggregate alternative energy into one centralized control and distribution system.
- – Electricity consumption is highly variable by region, season, and time of day. Even big appliances like refrigerators only use their rated power occasionally.
- – To estimate how much power you need is a fairly simple formula. Check this DOE website for estimating energy consumption.
6. The best question about power: How much usable electricity does WindStax store?
- – WindStax use sealed maintenance-free 100 percent recyclable deep cycle AGM (absorbent glass mat) batteries. We also use GEL batteries. The storage capacity of WindStax is measured in terms of amp-hours. The ampere-hour rating divided by the load in amps will provide the estimated time of that cycle. For example, a 12V battery rated for 200 Ah (for a 10-hour rate) will deliver 20 amperes of current for 10 hours under standard temperature conditions (25C or 77F). We use 12, 24, and 48V battery banks depending on the application.
- – WindStax base units arrive fully charged with 200-amp hour storage capacity installed. On board battery storage can be increased to 1200 amp hours. Add remote batteries and WindStax storage capacity is limited only by the wind and solar power available to keep them charged.
- – Moving batteries and electronics inside a building, we can increases storage capacity up to 15,000 watt hours (15kWh) at 20 hour discharge using revolutionary new Aqueous Hybrid Ion technology (AHItm) from Aquion Energy.
7. How much do they cost?
- – WindStax has two standard units 20 foot tall and 40’ tall. The base units are the core of our wind power systems. Each has the same ground footprint, the larger one is twice as tall. They arrive fully assembled, charged, and operational – plug and play.
- – Our mission is to provide reliable and affordable green energy with as little fuss as possible. The current price of our WindStax 20 is US $19,900. The WindStax 40 is $39,900. Contact us for accessories, upgrades, delivery, and installation pricing.
- – Depending on your geography and power needs, we optimize your unit with semi-custom options in the categories below. WindStax are scalable – we can upgrade your system as your needs change in the future.
- Annual estimated wind density
- Battery storage capacity required
- Peak and off-peak electricity demands
- Control requirements (for example, wired or wireless remote)
- Monitoring requirements (for example, we have a nifty complete weather monitoring station)
- Remote monitoring – we can monitor your WindStax performance remotely from our office 24/7, providing monthly output reports automatically.
Our experts will help determine the options right for your application.
8. What about installation, service and support? WindStax are lightweight, portable, and can be installed just about anywhere.
- – We can deliver and install the unit at your location or provide expert advice so you can do it yourself.
- – WindStax requires little maintenance with very few mechanical moving parts. However, we offer service contracts including an unprecedented 48-hour component swap-out service for electronics. If something breaks, we fix it right now.
9. What do I need to install one? WindStax are unloaded and moved horizontally, then tilted or lifted into place. We provide full-service installation of our units or we can manage a local contractor to perform the work.
10. What wind characteristics do I need for WindStax to work?
- – Wind speed and direction changes seasonally and even daily. Steady average wind speeds are best for wind energy.
- – WindStax operates in wind speeds as low as 5 mph and can withstand wind gusts to 90 mph. We have hardened versions for more hostile environments.
- – WindStax are omnidirectional – that is, they capture wind from all directions.
- – If the rotor is spinning, it is creating electricity. How much electricity depends on other factors like wind density, relative humidity, and elevation above sea level. WindStax come in several configurations designed to work best in your location and your power needs.
11. Am I in a good wind area? Do you have a steady wind approach – an unobstructed view to the Northwest, West, or Southwest (in the United States)? If so, chances are good WindStax may work for you.
- – WindStax work well in most Class 2 and higher wind power areas. Refer to the map above for a general idea of the wind classification in your area. Check the Wind Energy Resource Atlas of the US for more detailed wind power maps.
- – Higher elevations are great but we have found some good wind areas on lakefronts, ocean or bay fronts, valleys, and particularly river valleys in many Class 2 locations.
- – Contact us and we will provide a free wind analysis of your site.
- – We also have a remote weather station program available whereby we install pre-programmed equipment to record wind and weather data over time. Installation is simple and live data is sent to us remotely over the Internet. With this program we can project wind power very accurately for your location.
12. How noisy are they?
WindStax are so quiet you will struggle to hear any noise standing next to one operating. Even at high speeds, the ambient wind noise far exceeds the sound from our wind power system. For comparison, standing curbside on a busy street is about 80 decibels. Normal speech is around 60 decibels; the quietest small gasoline generator idles at 49-60 decibels. WindStax operate near 38 decibels – about the sound of a quiet desk fan at low speed from one meter away.
13. What is the carbon footprint of WindStax compared to diesel generators?
Diesel: 333 – WindStax: 0. The average diesel engine burns 99 percent of its fuel. The remaining 1% will fail to oxidize and will be emitted into the air as particulates or unburned hydrocarbons. The 99% that burns will produce, on average, 22.2 lbs. of CO2 per gallon of diesel. If your neighbor’s diesel generator burns 15 gallons of fuel per hour, it produces 333 pounds of CO2 per hour. (Cough)
14. Do WindStax qualify for alternative energy incentives or tax credits?
WindStax may qualify for green energy incentives from states, local utilities and federal tax credits. WindStax may qualify for the Residential Energy Efficient Property Credit, which is a 30% tax credit for the cost of our units and installation. There is no ceiling and you can carry over credits to subsequent years through 2016. Contact us or check the US Department of Energy’s database of State Incentives for Renewables & Efficiency for incentives available in your state.
15. What about zoning and other regulations?
- – WindStax are low enough to fly under the radar of most local zoning restrictions for windmills and towers.
- – WindStax may not be considered permanent structures under local zoning regulations, therefore requiring no building permit. Each locality is different. We suggest a quick call to your friendly municipal government office a
- – We can provide stamped engineering drawings for the foundation, which may be subject to local building codes.
- – If WindStax are tied to a permanent structure, local and national electrical codes must be followed.
16. Do WindStax attract or kill birds or bats?
- – According to USGS, bat fatalities have been documented at nearly every traditional turbine wind farm in North America. However, there have been no documented cases of bird or bat kills with vertical turbine installations.
- – WindStax are designed to capture wind energy at slow speeds within a small land and air “footprint”. In contrast, the swept area of large turbines exceeds 1 acre and blade tip speeds are 132-182 miles per hour.
- – Recent evidence suggests that insects are attracted to the colors of traditional wind turbines (usually white or grey to blend with the sky). Insects attract birds and bats. WindStax use natural materials and finishes blending perfectly into the environment.
