Bergey XL.1 -- This is the smallest machine I
currently use, it is 8.2 feet in diameter with a swept
area of 53 square feet and a rated power of 1 kw at
24.5 mph. It comes with a very sophisticated
controller that can also accommodate up to 800 watts
of PV panels. |
 |
AWP 3.6 -- This machine also has a rated power of
1kw, but with a rotor diameter of 11.8 feet and a
swept area of 109 square feet it will deliver nearly
twice the kwh/month of the Bergey XL.1. The AWP 3.6 is
a "heavy metal" machine, weighing in at 250 lbs. |
 |
Bergey EXCEL -- This machine has been in continuous
production for over 18 years with very few design
changes. With its new, quieter blades it has a rotor
diameter of 20.2 feet and a swept area of 320 square
feet. It is rated at 10kw (grid tie) and 7.5kw
(Battery charging). The simple design of this machine
results in very low maintenance. |

Jacobs 31-20 This is currently the largest machine
I handle with a rotor diameter of 31 feet, a huge
swept area of 755 square feet, and a rated power of
20kw. It is the modern desendant of the Jacobs from
the 1930s-1950s, known at the time as the Cadilac of
wind generators. It features a blade feathering
governor for overspeed protection. |
