My Woolies 23W job draws 210ma therefore it is a 50.4W globe. Is there a bit
of skullduggery going on here?????????

And what is the phase angle?

And what is the phase angle?


** It is undefined.

Cos you are not dealing with an all sine-wave system.

* PF = watts / VA *


Note: no cos phi in sight ......

They are advertising a $4K difference with local Toowoomba company here.
Get onto you local polly and start a movement to get a similar scheme
started. Costs the states zip, as the feds pay & the contracting company
is as busy as hell on a hot day.

There is 4 page "advertising report" lift-out in todays Sydney Daily
Telegraph about home solar systems.
One local company SolarSave (www.solarsave.com.au) is advertising a 1KW
system for $1,990 "fully connected".
Will have to look into it all...

$2K, won't take long to recoup at that price. Still get onto the pollies, ya
never know one have a working brain cell. I am working on a average output
of 8KWH a day. So at $3 a day will reduce my power bill and pay for itself
in less than 2 years. The pollies think it is cheaper to put these on a roof
or seven than to build a power station, well it is quicker. What are the
emisssions like at the factories that make these? Still gotta be less than
10 years of coalie.

Hi,

Telegraph about home solar systems.

Would be interesting to hear what you find.. Last time I looked, it was
all massively out of our price range..

Regards,

Ross..

And what is the phase angle?

typically fairly small, often current is leading by a few degrees.
the main reason for the low power factor (if you must analyse them in
the frequency domain), is all the harmonics.

Isn’t this the coolest looking light bulb you’ve ever seen? Philips’ new
Master LED light bulb gives as much light as a conventional 40-watt
bulb, but with a 45,000-hour lifespan, four times as much as a CFL and a
total power consumption of seven watts. However, with a price tag of $50
to $70 per unit, replacing all light sources in your home with LED light
bulbs could become quite the project. The Master LED Light Bulbs are
already on sale in Europe, but we won’t see them here in North America
until next July.
