Its a bit more complicated than just hooking a generator up to a lamp and
waiting for wind. Uunless you want unreliable variable brightness whenever
mother nature feels like giving it to you.

Think of it this way. You want to operate a 6000W load for say 8 hours,
thats 48kWh of energy you need to store and deliver on demand. So now you
need a battery pack that can hold that much energy and a power converter to
charge it and convert it back to whatever your lamps need (wise to use 12VDC
lamps and avoid an inverter alltogether). If all you wanted was one hour of
12V lighting then that 6000W will need a 500Ah battery and for 8 hours you
need 2000Ah of battery capacity. Thats probably what 2-4 car batteries to
be safe (my guess).

Now you need to be able to charge that battery during the daytime before you
turn the lamps on and any more wind you get at night can reduce that
requirement by a fraction. a 5KW generator running at peak power (quite
breezy) will charge that battery bank in 9.6 hours of continuous wind. a
10kW generator in half the time but requiring more wind force.

Derate that whole calculation by the reliability of your wind. or that
fraction of the average day when enough wind is present to operate the
windmill at peak power.

So it all depends on how long you want the lights on and how reliable the
wind is at that location. If it is unreliable and you want 12 hours of
light, you will need a 15kW generator for par. A bigger battery pack and a
fair start with a full charge will extend lighting time for occasional
windless days and nights but on average you need to replenish 110% of the
power you deliver to the load with newly generated power (10% estimated for
losses in conversion). A similar process is used to evaluate PV as well.

500W of incandescent or halogen lighting is inefficient, ballasted halide or
fluorescent lighting (anything called high efficiency or HE) will put out as
many lumens for less watts. When evaluating the best type of lamp consider
the lumens par watt, bulb lifetime and compatibility of the bulb voltage
with your system voltage. Some lighting has a turn on surge current rating
you need to account for at some level of the design

Hello

I have a little problem. I've got a private firm, the area which is
surrounded by a fence. I would like to light this area with twelve
500W lamps. Could one of those wind power plants

handle it? Best regards.
