It’s widely known that changing to
LED lights can save power, but just how
much? “LEDs use 7w compared to 50w
for traditional downlights,” says Florian.
“The cost of the LED light fittings is around
$100, compared to halogen downlight
fittings at around $25. Based on five hours
of use per day, at (Synergy’s rate of) $0.41/
kw, a halogen downlight will cost around
$40 per year to run, compared to an LED
at $6. So you can see LEDs will pay for
themselves in around two years, and save
money every year after that.”
Combined with the fact that LED lights
last much longer than halogen globes,
Florian says in the long run they are a
cheaper option by far.
Another option to reduce energy costs
is solar power. “At an average cost of
$3000 for a quality 2kw solar system, the
numbers stack up like this: daily electricity
consumption for an average Perth
household is 18 units (kw hours). A 2kw
system will generate roughly 12 units (kw
hours) of electricity per day and current
Synergy rates are of $0.41/unit (kw hour).

If you use more power at night when your solar panels are not active, then these figures will change,
as electricity suppliers like Syn ergy on ly pay you $0.85/u nit when you feed in to the grid, but charge
$0.41/kwh when you use electricity.
Use a wall mounted touch screen or an App on your iPhone, iPad, or smartphone to control
the entire house from anywhere in the world. You can watchCCTV cameras, check security
systems settings, open or close blinds, doors or windows, turn lights on or off, adjust the
air-conditioning or floor heating, and monitor energy usage.
