Step 4: Connecting the Flexi cable to a charge controller (if supplied)
4.1 A charge controller will be necessary
for STPVF020 and above and if using
the 010 on a battery smaller in capacity
than 70Ah.
4.2 Position the charge controller as
close as possible to the battery
(must be a dry location).
4.3 Measure the distance between your
battery terminals and the charge controller.

positive cable as close to the battery as possible.
5.2 Cut the red cable and strip 5mm of the red insulation from both the
cut ends. Twist the bare wire ends tightly. Fit into the screw terminals
on each of the fuse holder pieces.
Step 6: Connecting to the battery
6.1 If the STPVF010 has been selected, the crocodile clips can be
fixeddirectly to the terminals of a 12v battery (greater in capacity than
70Ah) ensuring that the correct polarity is observed. If a smaller battery
is to be used, purchase a charge controller and follow Step 4. This
entails checking the battery at regular intervals with a digital voltmeter
and when the battery is showing a volt reading of 14v or above,
disconnecting the Flexi PV until the battery level has reduced.
6.2 For the STPVF020 and above (where a charge controller is being used),
take the cable end coming from the charge controller, strip the red
and black insulation (6cm) from the inner cable ends, twist the bare

which case, strip 20mm of cable from the red and black cable, crimp the
supplied ring terminals and connect to the battery clamp screws.
6.3 When connecting to a battery always observe correct polarity.
6.4 If a second battery is being connected to the solar system see the
instructions contained within the charge controller.

Step 7: Testing the system
7.1 Testing can also be completed with a digital volt meter. Solar

Connecting an inverter into the system
9.1 Should you require your solar system to power 240V appliances, you
will need to connect an inverter. Select an inverter power (measured in

Warranty
Solar Technology International flexi solar panels are supplied with a 2 year
panel build warranty and 20 year cell performance warranty.
2 Year build warranty
This guarantee’s the panel from mechanical failure and water ingress during
this period. Void if the outer layers of the panel have been penetrated.
20 Year cell performance warranty
The solar cells are guaranteed to perform for the long term and this warranty
specifically confirms that by year 20 the cells will be outputting no less than
80% of their new value. For example, a 100wp solar panel is guaranteed
to deliver no less than 80wh by year 20 when tested under Standard Test
Conditions.
In the event of a successful warranty claim in both cases,
Solar Technology International will, at its discretion provide one of the
following remedies; 1. Replace the defective solar panel or 2. Refund the
percentage of the cost of the solar panel to the customer representing the
percentage of the time period between new and year 10 and in the case of
a claim on the cell performance a percentage will be paid according to the
power output less than 80%.
Solar Technology International Ltd does not accept liability for any 3rd party
damage how so ever caused or any costs associated with the return of faulty
products.

Step 1: Positioning the Flexi panel/s
1.1 Select a location that is generally free from shade, has a solid surface
and is within 3-4m of the Charge Controller and/or battery. If the Roof
Top Kit has been selected please also refer to Step 3.1.
1.2 If the panel is to be free standing, go to Step 2.
1.3 Ensure all panel/s can be sited close to one another (if a multi panel
system has been selected), and that the cables can be correctly
positioned. Note – cables from a multi panel system will be all fed
directly to the Charge Controller.

a 70 to 100mm gap in the centre of the panel. This allows water to exit
and air to travel between the roof and panel. Apply even pressure to the
panel to compress the adhesive from 10mm to 5mm.
On a ribbed roof use the same method but apply double lines of
adhesive on the peak of each rib, leaving the rib base open.
If the panel has a rear cable exit, apply a circle (or two circles if space
permits) around the junction box to ensure the roof hole is well sealed.

another agent.

PV Logic Flexi panels are designed to withstand the harshest environments on the planet from -40 to +80 degrees. The top surface is
made from ETFE, which is particularly resistant to damage, scratching and delamination. The surface has a special self healing property if
light scratching occurs. The cell circuit is fully encapsulated in a water tight envelope and mounted on a powder coated aluminium sheet
providing strength and heat dissipation without magnetic interference.

greater than this WILL cause micro cracks in the cell circuit resulting in premature failure. In these
circumstances the warranty provided with this product will be void.
2. If any kit comprising of a single or multiple 80w Flexi panel has been purchased and the rear of
the panel has a clear, dimpled surface (same as the top surface), please see attached special
instructions for bonding and ONLY use the glue and applicator provided in this pack. If the 80w
panel has a white back surface proceed as noted below and overleaf.

should be removed approx 20mm (longer if connecting the 10wp panel
direct to a battery) and the inner red and black cables will be revealed.
Remove this sheath and the copper cable will be visible (red is positive
and black is negative).
Now the supplied ring terminals can be crimped to the cable end for
either connecting to the supplied crocodile clips to connect direct to
a battery (STPVF010 only) or to a charge controller if a 20wp panel or
larger has been purchased. If wiring a multi panel system, repeat the

each gland grommet.
3.2 The Cable Feed Gland is a completely waterproof unit designed to
cover a hole that has been drilled to channel the Flexi cable from the
outside to inside. The location of the Flexi panel/s (as discussed in 1.1)
will have been determined, to a certain extent, by the desired location
of the cable feed hole. The cable entry point should allow the cable/s to
be easily routed to the Charge Controller (if used) and the battery.
3.3 Now slacken the feed grommet/s on the Cable Feed Gland to allow the
cable to be easily threaded through it and now allow the cable/s to pass
through the drilled hole.

roughly the same time as step 1.4 or 1.5.
3.5 Now push the cable/s from the solar panel(s) through the gland
grommet so that it is reasonably taught. The threaded grommet can
now be tightened ensuring a perfect seal is made around the cable
itself.
