LED’S MEASURE ACCURATELY

The SINUS-220’s accurate and precise simulation of the sun’s spectrum minimizes the danger of classifying solar cells with an incorrect efficiency rating.

Accurate measurement eliminates the necessity of safety margins when classifying. The SINUS-220 also prevents solar installations from generating yields that are far below target values. The risk of an incorrect classification resulting in customer complaints, negative reports from testing institutes and consequently harming the manufacturer’s reputation is also reduced. The SINUS-220 allows you to precisely determine the performance of solar cells and price them accordingly.

For solar module manufacturers, the SINUS-220 is ideal for inspecting incoming materials. Regardless of the quality of the solar cell supplier, cells are measured accurately. This allows defective shipments to be easily identified. As a result of the accurate classification of incoming solar cells, the SINUS-220 also increases the percentage of solar modules rolling off the line with high performance characteristics.

LED’S INCREASE EFFICIENCY

The SINUS-220 provides a nearly perfect simulation of the sunlight. And it does so consistently during each and every individual efficiency measurement across the entire lifecycle of the light source. This temporal stability of the spectrum eliminates the risk of inaccurate efficiency measurements.

In addition, the SINUS-220 also gives you the option of monochrome illumination. These measurements enable early detection of process problems, for instance at the front or rear contacts.

Consequently, process instabilities in the production line are uncovered rapidly and consistently. In addition, new processes developed in the lab can be more quickly and easily integrated into the production process. These factors all make a considerable contribution to a manufacturer’s competitiveness.

LED’S FLASH LONGER

High-efficiency solar cells require longer exposure times than standard solar cells when measuring cell efficiency. Xenon lamps only allow for short exposure times. As a result, most xenon lamps only allow you to estimate efficiency. The risk of overestimating or underestimating is everpresent.

The light source of the SINUS-220, however, enables long exposure times. The efficiency of high-performance solar cells can thus be accurately measured, which eliminates the risk of revenue losses and customer complaints.

LED’S REDUCE RUNNING COSTS

Conventional solar simulators use xenon lamps which age continuously and need to be replaced after only a few months of operation.

This results in:

  • Replacement part costs
  • Personnel costs
  • Costs resulting from production downtime

The LED-based light source of the SINUS-220, in contrast, can provide 24 months of reliable operation with minimal maintenance. Consequently, operating costs are significantly reduced.

LED’S BOOST ENERGY YIELDS

Efficiency is measured based on an international standard that provides a specific definition of sunlight. But actual sunlight varies greatly according to geographic location, season, and time of day.

The SINUS-220 makes it possible to vary the spectrum in order to sort or specifically optimize solar cells according to the regions they will be used in.

LED’S EXTEND MODULE LIFETIME

Sorting out solar cells that may generate hotspots is an important way of avoiding the associated efficiency and monetary losses. Until now, however, measurement methods have not been sufficient to accomplish this. Many bad solar cells are consequently not detected while some good solar cells are determined to be defective.

The next generation of the SINUS-220 will detect hotspots with an innovative process that takes into consideration all the physical processes involved. This will enable practically flawless classification, considerably reducing the potential for losses compared to previously used measurement methods.

LED’S IMPROVE COMPETITIVENESS

The SINUS-220 helps to lower operating costs and optimize product pricing for solar cells. Solar cell manufacturers can increase both their margins and their competitiveness with the SINUS-220.

Taken together, the six customer benefits deliver a six-figure economic advantage compared to conventional solar simulators — year in and year out.

Photovoltaic manufacturers will see a very rapid return on investment with the SINUS-220.
The bottom-line benefits of the SINUS-220 pay off in more ways than one in an industry marked by intense competition.
