Bergey’s “XL.1” wind turbine produces approximately 1 kilowatt of power (1,000 watts). It has a system that is direct drive, meaning it does not need a gearbox to translate the mechanical energy to electrical.
This system is designed to charge batteries only. If you are looking for a system to power your entire home and take you off the grid, Bergey has a 2 kW and a 10 kW system available.
First, a few facts about the XL.1…
• Cost $7010 for kit (turbine, PowerCenter, Tilt-up tower, Battery Bank, and Inverter)
• Cut-in speed 5.6 mph (speed where it begins producing power)
• Furling speed 29 mph (speed where it stops producing power)
• Max speed 120 mph (maximum design speed)
• Blade system 3 blade/8.2 feet diameter
The style of the XL.1 is horizontal-axis, which means the blades turn in a plane perpendicular to the earth. It looks like the classic windmill.
There are two components to pricing such a system that you need to plan for:
1. The first cost of buying
2. Installation of the assembled unit
The wind turbine kits come complete with the materials needed but, you will still likely need some help with mounting it and hooking it up to the electricity in your home.
To do this right, these are the steps to get your wind turbine up and warning – the latter two, you will want to consider subbing-out:
1. Purchase of the turbine from a Bergey dealer
2. Installation on roof or tower
3. Electrical interconnect
The great thing right now is the federal government’s 30% income tax credit for renewable energy purchases. That credit is for 30% of the entire cost of installation so, now is just a great time to get going, whichever renewable energy system you end up buying.
Is the turbine easy to get up and running?
The hard part really isn’t assembling the kit – if you are good with common household tools you can do that part. The difficult part is getting the install done right.
You need to make sure you have done your homework and know the best place to install the unit on your property.
How can things go wrong?
The mistakes people make are usually come from trying to do it all themselves. The “commissioning”, that is, the installation and electrical interconnect is best left for pros. That is a very critical item and it is too important to do incorrectly.
Plan on getting a mechanical contractor and an electrical contractor to finish the job.
There are a huge number of Bergey turbines out in the field that have been making power for years and they are reliable, highly recommended units.
