1. Birds - Do wind turbines harm birds?

A. Small wind turbines such as the EW50 generally have minimal impact on avian populations. Statistically, a sliding glass door or electrical distribution or transmission line is more of a threat to birds than a commercial-scale wind turbine. For more information please see this report.

2. Sound - How much sound does the wind turbine produce?

A: Measurable sound from the wind turbine at 100 feet is 64dB, 58dB at 200 feet, 52dB at 400 feet. They are generally not audible inside a home.

3. Insurance - Do I have to get a new insurance policy?

A: Frequently the wind turbine can be incorporated into an existing insurance policy that covers other similar capital assets.

4. FAA/Airports - How close can I put a wind turbine to an airport?

A: The EW50 height is well below the 200-foot threshold that requires lighting under FAA rules. FAA does require notification if the turbine is sited within 20,000 feet of an existing runway.

5. How much space do I need?

A: A single EW50 occupies a 60-inch base for a monopole and a 12-foot equilateral triangle for a lattice tower. A typical foundation is 20 feet square.

6. Is the EW50 appropriate for my house?

A: The EW50 is designed for commercial loads, but can be applied to very large residences.

7. Can I use my own tower? Can I buy just the turbine?

A: The turbine and tower system is designed as an integral unit to account for loads including thrust and weight.

8. Can I put an EW50 on top of our building?

A: The EW50 is designed to be installed on a professionally engineered ground foundation and connected to the grid.

9. How much does it cost?

A: The EW50 is competitively priced for the North American wind market. Please contact our sales staff for specific pricing.

10. How much does it cost to install?

A: Installation costs vary depending on site, terrain, and existing infrastructure. Entegrity engineers help to determine the most cost effective method of installation.

11. What is the life-expectancy of the EW50?

A: The EW50 has a 30-year design life until major overhaul and with proper maintenance can last even longer.

12. What grants and incentives are available in my area?

A: State and federal incentive programs vary depending on location and market segment. Please visit our incentives page.

13. Can I sell energy back to the grid?

A: Yes, the EW50 is designed to be grid-integrated.

14. Who takes care of the turbine?

A: Entegrity provides comprehensive operations and maintenance support through Entegrity's 24/7 monitoring system that is included in the price of the turbine for the first five years.

15. Does it come with a warranty?

A: Yes, the EW50 comes with a 5-year limited warranty for all non-remote U.S. and Canadian installations.

16. How much can it save me in energy costs?

A: Energy savings depend on wind resource and your local cost of energy. Entegrity staff will help determine this value once we receive your location and utility bills.

17. Will the EW50 work well for off-grid and hybrid applications?

A: Yes, with proper power controls the EW50 can be integrated into off-grid and hybrid applications.

18. Is the EW50 suitable for coastal installations?

A: Yes, the EW50 is available with an optional coastal package.

19. Is the EW50 suitable for Arctic Applications?

A: Yes, the EW50 is available with an optional Arctic package.

20. What is the wind survival rating?

A: The EW50 is an IEC class 2 wind turbine and can withstand 135 mph wind speeds.

21. Do I need a building permit to erect the turbine?

A: Building permit requirements vary according to site location and application.

22. Do I have enough wind for the EW50 turbine?

A: The EW50 can be an economically prudent choice to control energy costs in a variety of wind resource areas depending on cost of energy, policy, and other considerations. Please contact our sales staff for a wind assessment.
