ANTARIS AS M 185 AI – The module
with the greatest energy yield
Sales of photovoltaic systems are booming. However, to achieve an overview of what is available in the market requires some corresponding information. As in 2009, the TEC Institute also tested 15 modules this year from well-known photovoltaic system manufacturers. The test was conducted under real conditions again. A laboratory test would only have been of limited use in delivering objective test results. In terms of the weather conditions, there was a mixture of sunshine and cloudy skies. The basic preconditions for realistic measurements were provided: the TEC Institute operates its own weather station that records temperature, air presure, wind, rainand humidity, and also includes a pyranometer for measuring global irradiance (the total solar radiance incident on the earth’s surfac as measured on a horizontal surface area). This enabled the weather conditions during the test phase to be precisely recorded parallel to the determined yield values and thus made it possible to objectively assess the actual energy yields from the different modules. With the comparison test, the ANTARIS AS M 185 AI module was awarded the best result of 1.1 for achieving the highest energy yield per individual module, and was therefore voted best in test.

ANTARIS AS M 185 AI:
The module with thegreatest energy yield

The 15 modules from various well-known manufacturers were measured over a period from 1 May 2010 to 30 June 2010.The voltage and current on the module side were measured at 1-minute intervals. This data was used to calculate the DC output and the electrical power delivered by the modules. All module types were tested in strings (2 or 3 modules respectively) and faced due south so that there was no shading. It was also ensured that all test strings had precisely the same cable length. The operating range of all the module pairs lay within the inverters’ MPP range. For each string, a ‘Mastervolt Soladin 600’ inverter fed the electricity into the grid. On the AC side, a feed meter measured the energy fed into the electricity grid from each string. This year also, none of the tested modules achieved a 100% energy yield, but eight came close and only five came very close.The ASM 185 AI from ANTARIS SOLAR with its monocrystalline cells achieved an energy yield of 251.2 kWh/kWp (equivalent to 99% of an expected energy yield of 100%). A comparison with competitive panels from 3 other manufacturers also rated “very good”, but which did not quite achieve as much energy yield as the ANTARIS SOLAR ASM 185 AI, can be seen in the diagram on the front page and in the table above.
