We build "WIND POWERED GENERATORS". We do NOT build "wind turbines".

The following are estimates for efficiency comparisons

A non-shrouded VAWT can lose as much as 95% of its energy to structural wind loading and anti-rotational wind loading. The non-shrouded VAWT is estimated to be only 5% efficient per wind sweep area. Thus, the price that you pay for it in wind loading per actual watt hours earned can be very high.

A correctly shrouded VAWT can lose as much as 90% of its energy to structural wind loading and anti-rotational wind loading. The correctly shrouded VAWT is estimated to be only 10% efficient per wind sweep area. Thus, the price that you pay for it in wind loading per actual watt hours earned can be very high.

A three bladed aerofoil lifting wind turbine can lose as much as 85% of its energy to structural wind loading and anti-rotational wind loading. In addition to that, it can lose as much as 96% of its potential for wind load convertible energy by the wide open spacing between the blades. In addition to that, it can lose as much as 70% of its energy to aerodynamic non-alignment ( see aerodynamic characteristics from sandia laboratories ), which is so variable that we will ignore it for now. Being generous, the three bladed aerofoil is estimated to be only 1.2% efficient per wind sweep area. Thus, the price that you pay for it in wind loading per actual watt hours earned can be even higher than the VAWT.

Our Wind Powered Generators, with our version of "flat plate technology" are estimated to be less than 40% efficient per wind sweep area. Even with ours, there is loss due to structural wind loading and some anti-rotational wind loading.

When you purchase, THINK about what you are getting.

If we do not consider the supporting structure, and just the design of the blades themselves:

Non shrouded VAWT = approximately 5% efficient. NO !

Correctly shrouded VAWT = approximately 10% efficient. NO !

3 bladed aerofoil lifting wind turbine = approximately 1.2% efficient. NO !

Our Wind Powered Generators = approximately 39.65% efficient. YES !



We have used the "~" sign occationally. Some of our international viewers may have been confused by this symbol. It means that a number is approximate. "~" means "approximately", as in "~1" should be read as "appoximately 1".



Of course these are estimates. Different manufacturers will have different percent efficiencies. Even our different models have different efficiencies. These are estimates, but it is something that you should think about. Know what you are buying. Think before you purchase.

How to determine your: wind velocity rating

You need TWO numbers:

(1) Multiply the AVERAGE yearly wind speed by 1.538 ( or x 100/65 )

(2) Multiply the AVERAGE yearly wind speed by 1.25 ( or x 100/80 )

That gives you the range of the rated wind velocity that is used to estimate the maximum rated output.

---

For example: ( A customer with 6.0 m/s wind speed would use the following.)

Generally, the yearly average wind speed is 65% to 80% of the maximum estimated commonly usable wind speed.

This can be very easy. Follow the steps outlined here and then chose the Wind Powered Generator model that you need.

Calculations:

(1st number that you need)

( 6.0 m/s ) x ( 1.538 ) = 9.228 or we can round that to 9.2 m/s
Thus the first number is "9.2 m/s"
6.0 m/s is about 65% of 9.2 m/s or 20.6 mph.

(2nd number that you need)

( 6.0 m/s ) x ( 1.25 ) = 7.5 m/s
Thus the second number is "7.5 m/s"
6.0 m/s is about 80% of 7.5 m/s or 16.7 mph.

Therefore the rated wind speed in meters per second is from from 7.5 to 9.2 m/s ,

Or if you started with miles per hour, then it would be from 16.7 to 20.6 mph.

This energy conversion range can vary due to the density of the air passing through and other factors. If the air is dry and hot, the density of the air could be low and thus the energy conversion could be low. If the air is cold and wet, then the density of the air could be high and thus the energy conversion could be high. If it is raining with lots of volume then the energy conversion could be even higher. The density of the air also has to do with elevation, or height above sea level.

Use the following table. It is there for you.

Look on the next table. In the left column chose the kilowatts that you need. In the right columns chose the wind speed that is closest to your required rating.

---

You have a choice EITHER

(1.) Do the conversion to find the rating for your order.

or

(2.) Simply order the Wind Powered Generator of your choice.

The common house in the United States of America has 200 amp service and 240 volt capacity.

That is 200 X 240 = 48,000 watt service capacity into the house.

If you live in the USA then that is 48,000 watts for whole house service.

Something to think about.

Option: Computer Data Interface

We can add a computer data interface to the ordered Wind Powered Generator which is either USB configured or CAT5 Ethernet Network configured, etc., from which (1) the prevailing wind speed; and (2) the Wind Powered Generator's blade rotational speed; and (3) the output voltage, and output current, and output wattage are supplied. The computer interfaceable system is $14,000 for the Wind Powered Generators which are 20KW or less, PLUS the price of the ultrasonic anometer. Higher wattage requires higher capacity igbt's ( insulated gate bipolar transistors ) which cost more and we would adjust the price for systems above 20KW.

This system requires an ultrasonic anometer for measuring the wind speed which would have to be decided upon by the customer.
Three types are available:

Standard: http://www.youngusa.com/products/6/1.html (list price is $1,522.00)
Heated: http://www.youngusa.com/products/6/2.html (list price is $2,134.00)
Marine: http://www.youngusa.com/products/6/44.html (list price is $1,748.00)

This does NOT include a computer and an operating system. A standard laptop or personal computer is expected to be used by the customer.

This DOES include installation software which is designed to work with Microsoft Windows 2000, or Windows NT, or Windows XP, or Windows Vista, or Windows 7, or Windows 8.

This DOES include a NEMA classed enclosure for the computer interface connection at the pole ( the class is decided upon relative to the expected weather conditions) ( http://www.nema.org/prod/be/enclosures/upload/NEMA_Enclosure_Types_11-05-2.doc ) ( unless a wireless data transfer system is supplied ).

This DOES include either

1,000 feet of CAT5 (or CAT5e) shielded direct burial cable.
or
a wireless data transfer system.

That is $14,000 for the software and the system, fully built in and ready to use on the Wind Powered Generator, plus the price of the chosen ultrasonic anometer.

If this is ordered, then it MUST be ordered WITH the Wind Powered Generator, as it is a built in system and NOT to be added later.

This does NOT include a computer and an operating system. A standard laptop or personal computer is expected to be used by the customer.

Option: Volume order discounts

These apply specifically to wind powered generators, and not to any other type of item.

If you order in volume then we can order our parts in volume, and we can give you a discount:

To receive discount, full order must be prepaid.

Total units per fully paid order is 5 to 10: Discount = 3%

Total units per fully paid order is 11 to 20: Discount = 7%

Total units per fully paid order is 21 or more: Discount = 9%

These discounts are IN ADDITION TO any other discounts and are removed from the listed sale prices of each item. For Example that means: If you use someone else's reference number and get a $500 discount for telling us who referenced you, and you also order in these volumes then the volume discount comes first, and then the additional $500 is discounted. If you purchase in volume, and get a volume discount, then the list price of the items that you purchased are considered to be listed at the volume discounted price for warranty consideration and warranty valuation.

Considerations: Tower Foundations

Tower foundations must be designed for your local ground stability conditions. Different soils require different tower foundations. Your Wind Powered Generator must have the proper tower and foundation to handle the wind speeds that are in your area. We do not sell towers. We do not sell tower foundations. We suggest that after you receive your Wind Powered Generator from us that you go to your local sign company and tell them that you want a tower and foundation capable of handling a sign which is the same area as the blade sweep of your Wind Powered Generator.

Generally, we have found that local sign companies, when told the sweep diameter of the blades, and asked for a tower that will handle that diameter flat surface as though it were a sign, will give a solid price for the materials and labor for the tower and foundation. Locally, to Frederick, Maryland, a 25 ft tower for our 14 ft diameter model is about $7,800 including foundation and tower and material and labor. Remember our Wind Powered Generators are designed for "low wind speed startup" and may not require an extremely tall tower to work.

Considerations: Grid tie pricing

Grid Tying your Wind Powered Generator must be coordinated with your local utility company. Different utility companies have different requirements. Different utility companies can require different grid-tie inverters (or paralleling switchboards, or grid interconnections) and this must be handled after you receive your Wind Powered Generator. We do not sell grid-tie inverters. We can suggest some companies that do. A search on Google for "Grid Tie Inverter" or "paralleling switch board" may show you suppliers local to you.

Generally we have found that Grid-Tie Inverters (sometimes called Paralleling Switch Boards) cost about $9,000 for a 15KW system. We have spent many months researching this, and have found that when asking for a grid-tie inverter price it is best not to say exactly what energy source it is for since a lot of these are mostly distributed by solar cell PV companies and they have tended to get exceedingly jealous of our sales. Whaaatever. We do not manufacture grid tie inverters. We do not sell grid tie inverters. A grid tie inverter is a grid tie inverter. No matter what the solar cell people tell you. We can manufacture with AC output or DC output in either single phase or three phase. No problem for us. No change in price. If you decide to purchase a grid tie inverter from a solar cell company, and they get upitty and snotty about what the source is, simply ignore their attitude and ask them what they require: "AC or DC?", "Single phase or three phase?". If they do not give you an answer, then mark them off your list and ask someone else for a price. Remember to look in Google for "paralleling switch board". A little insight here: look for grid tie inverters that use DC (direct current not alternating current) from the source.

Considerations: Shipping your ordered Wind Powered Generator

Shipping ! For delivery over land by TRUCK or for delivery over sea by SHIP !

You must pay shipping directly to the shipping company seperate from purchasing the Wind Powered Generator. After your Wind Powered Generator is built and all crated up and ready to ship, you (or we) can get a price from

Bennett Motor Express LLC,
  or
CaseStack,
  or
Freightmonster.com,
  or
Globaltranz.com,
  or
Great Bear Transport LLC.,
  or
High St. Logistics, Inc.,
  or
Reliable Transport Solutions,
  or
Schneider Logistics

for the shipping cost. Please contact the carriers on this list! They all were polite enough to tell us that they are looking for your business. You may do well to use a shipping company that cares about having you as a customer. For them to directly ask us to list their company is important. Please check the companies on this list. You chose the shipper that you use.

REMEMBER WE SET THE DEFINITION Our pictures on this web site are renditions for conceptional purposes only. The " Wind Powered Generator " that you order will definitely not look like that. The design may be similar, but it will be different in blade size, in sweep diameter, maybe in color, etc. This is to show you that you do have a choice: Those three bladed things are not your only option. July, 2012 Here in Maryland, USA, the state legislature has told us that if an individual produces electric (with up to 30KW of a grid-tied wind powered generator), and sends that electric into the electric utility grid, that Maryland state law forces the electric utility company to pay that person 100% FULL GENERATION RATE (excluding transmission and distribution) for that electric. * You should verify these laws yourself before acting upon this. * Utility: BGE, report of "Starting on June 1,2012"     rates link   Net Metering If we use a conservative $0.0700/kWh as an example On a persistently windy hill, here is a potential : (24 hours / day) X (365 days / year) = 8,760 hours / year (8,760 hours/year) X (30KW / hour) X ($0.0700 / kWh) = $18,396 PER YEAR Also, you might be shocked at the price that high-carbon-footprint manufactuing facilities are paying for RECs (Renewable Energy Credits). Seriously, you might thank us for telling you about it. We manufacture and sell Wind Powered Generators. Obviously this is NOT some silly, illogical, waste-of-space, aerofoil-lift , wind turbine .
