Testimonials.
In
the end, it is what our customers say that really matters.
Here are the comments of some of them:
Johnny
Hanekom, Keetmanshoop, Namibia: The two (2) machines
that I've bought, exceed all my expectatoins as far as
power generation is concerned. I am really pleased with
their performance, and I am planning to buy the third
unit.
Johnny
van der Linde, Groblershoop: We are retired on our
farm outside Groblershoop, and have always experienced
a shortage of electricity from the solar panels we had.
With our Winglette wind generator now installed, we are
seeking ways to utilize the abandance of power thats available
now!
Nico
Grobler, East Coast, Mozambique: We have a holiday
home near Vilancuro, and are well please with our Winglette.
Being a pilot for the South Africa Air ways, I just love
the Winglette's modern technology and good looks!

———Battery
bank sizing...
How to determine the Size of the Battery array
that will work well for your needs:
The first thing that you will have to decide on is the operating
voltage of your system, whether a 36Volt of 48Volt
system. The higher voltage systems is slightly more effective,
but a little more expensive. We found that independent home
owners mostly prefere the 36Volts packages, while the communication
industry rather the 48Volts systems.
Sizing your battery bank and inverter is elementary math's.
Power is measured in Watts. The formula to determine watts is as follows: (Watts = amps
x volts. ) Appliances wattage is usually listed on the manufacturer's
label. After you've collected this information about all the
items that you want to power off your system, you are ready
to determine the battery size you will need.
STEP
1:
Determine your daily energy budget. Make a list of
all the appliances that you want to serve with power. List their
Watt ratings and list an estimate of the number of hours that
each item will be used per day. Multiply the watt ratings with
the hours used per day, to determine the daily watt-hours per
items. Add these values together, to arrive at a total budgeted
watt-hour needed per day.
STEP 2:
Multiply total daily Watt hours needed by the number of anticipated
days of autonomy, to determine you basic battery
size requirement. (For excellent wind conditions choose 1. For
poor wind conditions choose 3.) This figure we call you basic battery size.
STEP
3:
Multiply this basic battery size by 2, to determine safe
battery size.
STEP
4:
Now, convert this safe battery size, to amp-hours as follows: Safe battery size expressed in Amp-hours = Watt hours / DC
volts. (DC volts is the operating voltage you've chosen
for the battery bank. For small systems it is normally either
36 volts or 48 volts. For larger system is can be 110 Volt,
240 volt or 600 volt.) With this figure for a Safe battery size,
expressed in amp=hours, you can go
and shop around for a suitable battery bank.
STEP
5:
To determine the correct inverter size,
total the wattage requirements for all the appliances you plan
to run simultaneously. Add at least 25% to this perceived requirement.
The final check is to look for surge watts of any item
of you appliances that might exceed your inverter size. Choose
an inverter size to suite this requirement.. and if in doubt,
go for one size up.
