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.

Solar powered golf cart 160w ultra light flexible panel Extended drive times up to 14 miles Easy installation Compatible with all 48v carts Eliminate over 1000 lbs of C02 per year Significantly extend the battery lifetime to eliminate costly replacements 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
