Safety, weather, etc.
Safety is a key concern for small wind systems, and it is important to take precautions to ensure that an installation does not present an hazard. Safety should be ensured with respect to:
- Towers. Climbing of towers by the owner or maintenance persons is a potential liability. Special safety precautions are also required if children have access to the system.
- Icing. In cold regions, ice can accumulate on wind turbine blades and pose a safety concern.
- Batteries. Hydrogen venting from batteries is another potential safety issue.
Consult with your dealer/installer to ensure that these and other issues have been addressed.
In some parts of the country, the environment is very hard on equipment and can cause operational and durability problems for the wind energy system and batteries. Special turbine components, lubricants, and maintenance schedules may be required to keep the turbine in optimal generating condition. Corrosion of system parts at locations close to the ocean can also be a problem.
Electromagnetic Interference (EMI)
Small wind turbines, such as those sized for residential and farm use, have not been found to create interference with television signals. In fact, small wind systems are commonly used today to power remote telecommunication stations for both military and commercial uses. Most wind turbines use blades made of wood, fiberglass or composite materials that don't cause reception problems. Many years ago, a few wind turbines equipped with long, metallic blades did cause some localized problems, but they are no longer commonly used.
