The Great Barrier
Reef Marine Park Authority engaged our services in 2007 for a
project on Low Island in Far North Queensland. The island lies 13km off
Port Douglas and is an important tourist destination which receives
approx. 100 visitors a day.
Following
a review of the existing, but faulty hybrid power system we identified
various options for a system refurbishment.
The selected
option included the replacement of 9 PV modules, changes to the field
wiring, a rebuilt inverter system and a brand new 600Ah, 120V battery
bank.
The
generator then ran for less than 2 hours a day compared to 24
hours before - a 90% reduction in emissions, fuel costs and
barging costs.
In 2008
we were asked to extend the now reliable system by 5 kW peak PV modules to
a total capacity of 9 kW peak to achieve an all year emission-free
status on the island.
In July
2008 we installed 30 Schott Solar 170 Wp modules together with 2
Plasmatronic HVPL regulators on a custom built galvanized steel frame.
Since then the noisy diesel generator has retired and is
only required during times of extensive over night visitation.
The
generator is fuel by biodiesel so even when it is needed emissions are
low.
Below are images of the system expansion and the new system built on a custom designed cyclone rated frame.
