LJW Solar Trackers have been designed and made in Australia by Luke Williams the owner
of LJW Solar for over 20 years. Luke’s years of experience has resulted in a product that
is proven and has stood the test of time.
Solar Tracking is a way to increase the performance of a solar array by more than 30%. Solar panels
perform best when they are facing directly towards the sun. When Solar Tracking is used
for an off grid systems there are a number of advantages. The additional hours of charging
will increase the longevity of the batteries. The extended life of the batteries will keep
the running costs of the system lower. Your batteries will be charged earlier in the day
resulting in more usable power available without drawing down on the batteries. Solar Trackers
follow the path of the sun from sun rise to sun set rotating fully from east to west each
day. Solar Trackers are also able to be adjusted according to the different seasons. When the
sun is high in the sky for summer the panels need to be facing almost straight up. In the
winter when the sun is lower the panels need to be tilted towards the north, (in the northern
hemisphere trackers face south). Solar Trackers can improve the performance of a solar water
pump up to 65%.
LJW Solar Trackers are a rotating solar panel framing system. Solar Trackers come in a range
of sizes from 6 to 60 panels. The frame and head assembly are mounted to a pole which
is concreted into the ground. The panels are bolted to the frame. There are two axis points,
one for daily movement and the second for seasonal adjustment. On larger units the seasonal
adjustment is automatic. The daily movement is computer controlled and driven by an actuator.
The actuator is programed for the location of the site to automatically follow the suns
path. All of the components are weather proof and the metal structure is galvanised steel.
The power to run the actuator is supplied from either the off grid power supply or a
separate power pack.
Our trained installers are able to install the trackers within 1 to 2 days. In most cases
excavation of the trackers, the foundation and trenches is required to be done by the
client prior to the teams arrival. Footing sizes vary depending on the size of the array
and we will discuss these with you before installation.
Solar Trackers need minimal maintenance. There are a number of grease points that should
be attended to every 6 months. The owner’s manual will give specific instructions for
individual designs. Solar Trackers are generally rated to 12 meters per second of wind screen.
Larger units have wind switches which automatically adjust the unit to the center to prevent damage.
The site inspection and shade analysis would be done prior to installation to insure the
location is suitable. For further information on tracking systems and to find out what is
suitable for you please call LJW Solar on 1300792011 or visit our website www.ljwsolar.com.au
