WARNING
• For installations with lead acid batteries, avoid sparks or flames near the batteries and always use proper
eye protection.
• Given sufficient light, solar panels always generate energy even when they are disconnected. Accidental
‘shorting’ of the terminals or wiring can result in sparks causing personal injury or a fire hazard. It is
recommended that the front face of the panel(s) are covered with a soft cloth to block incoming light
during installation and wiring.
• When connecting panels in series do not exceed 24VDC (Max. 2 panels).
• Do not scratch or bend solar panels.
• Do not disassemble the solar panel frame.
• When mounting solar panels at a height adhere to all relevant safety regulations.
• For fixed installations ground the frame of the solar panel(s) to reduce lightning hazard.
• Do not walk on modules.
• Do not attempt to increase module output by concentrating light on its surface with mirrors.
• Be sure to use components (cables, fuses, etc) with ratings greater than 25% of solar panel/s maximum
current ratings.
FEATURES
COMPACT AND POWERFUL
Monocrystalline solar panels are manufactured from a solar cell that is cast from silicon. These cells are more
efficient at producing power than polycrystalline and amorphous panels, so the size of the panel is smaller yet
produces greater output power.
HEAVY DUTY FRAME
Corrosion resistant frames are constructed to withstand wind speeds in excess of 130 km/h in typical ground
mounted applications. The frames are clear anodized and the inner corner connection has a strong mechanical
resistance to weather.
TEMPERED LOW IRON GLASS
Clear encapsulated insulation enhances solar cell performance and provides proven weather protection,
Tempered low iron glass provides both better impact resistance and better light transmission, allowing the
generation of more electricity by reducing the quantity of light that is reflected away from the module.

INSTALLATION
PLACEMENT
Locate the panel in a position where it is exposed to the sun for the majority of the day. For best results use a
northern orientation. Make sure that the front side (dark side) of the solar panel faces the sun. Although the
panel will function in the horizontal position, for best performance tilt the panel towards the sun especially
during the winter months in the southern states. The angle of the tilt should be similar to the angle of the sun
so that the panel is perpendicular to the sun rays. Recommended angles for Indonesian, Australian & New
Zealand latitudes are shown below:

MOUNTING
The panels are supplied with four or eight mounting holes (depending on the model). Use suitable
fasteners and mount the panel to a flat surface or mounting frame as per fig. 1, 2 & 3. Ensure the battens
or frame does not twist or bend the solar panel’s aluminium frame.

CHARGE CONTROL
Solar panels are most commonly used to charge lead acid batteries. Projecta solar panels are designed to
charge 12 VDC batteries. 24VDC batteries can be charged using 2 panels wired in series and using a 24VDC
solar charge controller.
For battery charging it is recommended that you use a Solar Charge controller to prevent the battery from
being overcharged (damaged) and prevent the battery from discharging (loosing power) into the solar panel
at night. Solar Charge controllers are connected between the solar panel and the battery.
Projecta 12VDC Solar Charge controllers:
P/No. SC005 – 7 AMP Automatic Solar Charge Controller (suitable) for solar panels up to 80W.
P/No. SC010 – 10 AMP Automatic Solar Charge Controller (suitable) for solar panels up to 120W.

CONNECTING SOLAR PANEL TO BATTERY
Projecta products are covered by a 12 month warranty. Failure to follow the operating instructions
may damage the product and will void warranty. Please read these operating instructions carefully
before use. For a warranty claim please return unit to the place of purchase with your sales receipt
as proof of purchase date.
Single Panel, 12V Installation
You will also need:
• Suitable solar controller
• Suitable cable. (If solar panel is within 3 metres from the battery use 4mm cable, within 6m use 5mm cable
and within 9 metres use 6mm. It is not recommended to run longer than 9m.)
• 10A Fuse or circuit breaker.
1. Connect a fuse or circuit breaker to the positive terminal of the battery, (As near to the battery as possible)
refer to Fig. 4. Leave the fuse out.
2. Connect a cable from the fuse or circuit breaker to the solar controllers’ positive terminal.
3. Connect a cable from the battery’s negative terminal to the solar controller’s negative terminal.
4. Connect the solar panel to the solar controller. Ensure positive to positive and negative to negative.
Refer to Figure 5.
5. Insert fuse.
