QSOLAR NOW OFFERS A REVOLUTIONARY PV PANEL
MANUFACTURING PROCESS WITHOUT THE USE OF
LAMINATORS, GLASS, EVA OR TPT!!!
As we believe that nothing is carved in stone, we have changed the entire solar
panel manufacturing process, using our proprietary patent pending Spraytek99®
and ESS® technology.
What is the main problem in conventional solar panel manufacturing?
The major bottleneck in any automatic PV manufacturing line is the lamination process; this is why production lines use
multiple laminators to achieve the required throughput. The reason is the time it takes to cut and position the EVA sheets
for encapsulation of the solar cells as well as the actual lamination process. This leads to significant increase of the total
investment and operational cost.
Why is Qsolar’s SPRAYTEK99 ® manufacturing process better?
At QSOLAR we took a different approach in improving an already established technology using the crystalline silicon cells;
but instead of using an expensive laminator to seal the cells, we have adopted a spraying technique we call SPRAYTEK99 ®
using a highly protective insulator plastic compound which forms an impenetrable film around the cell protecting it from the
weather under any conditions.
Design of a conventional glass solar panel
Disadvantages:
•Requires an expensive flat bed laminator, production expansion is therefore costly.
•Lamination requires a significant amount of electricity.
•Solar panel sizes are restricted to the size of the laminator
•Restricted to conventional materials such as solar glass, which is heavy and breakable.
Design of QSOLAR module
Advantages:
•Manufacturing process is 35% faster
•Manufacturing does not need a laminator machine, reducing capital expenditure significantly.
•Major reduction in the use of power during manufacturing
•Not using Solar Glass, TPT or EVA
•Qsolar can vary the backsheet! Instead of glass we use an ultra light composites which are 50% lighter in
weight and stronger than glass.
QSOLAR has developed a new solar wafer
manufacturing process " The Crucible Cell "
pushing the boundaries of cost effective solar
manufacturing to new levels. With the adoption
of this advanced patented technology
(KRUCIWATT®) enables the company to cut
down significantly on polysilicon consumption
Conventional wafer manufacturing processes consist of growing large
ingots of silicon in furnaces and then cutting them with wire saws into
thin wafers. This process results in material losses of up to 50% from the
silicon dust produced during cutting. The silicon dust can not be reused
as it is no longer pure to the level required for solar wafer
manufacturing.
KRUCIWATT®, Qsolar’s new Crucible Cell process, eliminates this waste
and leads to up to 50% saving in silicon material which in turn results to
up to 20% saving on the cost of the finished solar module
The new ICYCELLS® design from QSOLAR consists of 3
different cooling systems:
•
•
•
A new UV reflector coating on top of the module that
will reflect 99% of the UV so the panel remains cool.
A 10mm hollow polymer backsheet with air cooling
ducts where air can circulate underneath the cell
High quality silver tab ribbons elements
Solar panels with the ICYCELLS® design allow air to flow through them. Increased ventilation helps cool
down the solar panel and will guarantee peak performance every time
ESS – Embedded Solar Solutions
SPRAYTEK 99® solar manufacturing
process opens a wide range of new
applications in the solar market. With
the ESS ®SPRAYTEK process, solar
cells can be
This technology allows true
integration of solar electricity
generation as the solar cells can be
encapsulated on materials such as
concrete, wood, bricks, tiles and
more.

•Significantly extend the battery
lifetime to eliminate costly

In typical use, a golf cart battery is discharged to twenty percentage of capacity (80% discharge). In this usage, batteries will
need replacement after 520 charge cycles or 1 3/8 years.
Use of a Qsolar solar panel reduces depth of discharge to no lower than 30%. In most cases through typical cart use the battery
discharge will be in the 30%-50%, equaling a gain of more than double in battery life.
In one test case, battery discharge depth was limited to 10% of the battery capacity. Battery lifetime for this battery could be
extended to 5000 charge cycles
