Installation
The Skystream 3.7® was designed to be easily installed. Your Skystream dealer can help you with all the details.
PERMITTING, ZONING, AND UTILITIES
It’s important to understand what your local government allows and requires. Your Skystream dealer can provide guidance and support while you work with your city or county to get the proper installation permit and with your local utility to connect to the electric grid through your electric meter.

PROPER LOCATION
STEP 1: Determining your wind resource
There are several ways to ensure you have at least a 10 mph (4.5 m/s) average wind speed.
- Check wind maps for your location
- Local authorities such as weather stations
- Checking your surrounding trees for indication strong wind flagging
- Site assessment and monitoring by professional third parties
STEP 2: Locating the system on your property

The general rule of thumb is to install your Skystream at least 20 feet (6 m) above any surrounding trees or structures in a 250 foot (76 m) radius.
STEP 3: Ensure proper generator height
In most cases, a taller tower will allow you to generate more energy. Taller towers, however, increase the cost of your installation and may not be allowed in some areas. A Skystream 3.7 commonly requires a monopole or guyed tower. Below you’ll find a siting guide and information on the most common tower options.
