Rayotec Solar solutions have excelled in tests conducted by the LEEE-TISO laboratory, the Stiftung Warentest, the University of Oxford, and the Fraunhofer Institut. These independent tests show the strength and versatility of SCHOTT's solar panel modules.
Thirteen of SCHOTT’s solar panel modules were entered into the Stiftung Warentest in September 1999. Among the areas tested were power, function, documentation and electrical safety.
The winner of the test was the SCHOTT ASE-300-DG-FT (285Wp) solar panels, which achieved an excellent grade of 1.8.
A number of SCHOTT’s solar panel modules were submitted to an independent study by the University of Oxford along with manufacturers of other solar panels as well as other types of solar technology (CSi, ASi, CIS and CdTe). All of the solar panel modules were tested in two different locations in England and Mallorca.
The SCHOTT ASE-300-DG-UT solar panel was the best module with crystalline solar cells and out-performed all the other modules in Mallorca’s warm climate and also accomplished the second best electricity yield in England’s cooler climate.
The "LEEE-TISO" Laboratory (Switzerland) anonymously purchased solar panel modules from a variety of manufacturers. The laboratory measured the performance initially and at set intervals after installation.
The SCHOTT solar module (the ASE-100-GTFT) achieved the best results in both initial and all subsequent tests. The performance gap of the SCHOTT solar module only above the competitors increased as the power of many of the competing modules decreased over time.
SCHOTT’s solar power modules were submitted to the Stiftung Warentest tests again in 2005/06. In total thirteen crystalline and two thin-film solar panel modules were tested.
The results for the SCHOTT ASE-165-GT-FT/MC solar panel were above average in total as well as in the specific areas of electricity production and safety. It was also commended for “sehr gut” (very good) ageing resistance.
The Fraunhofer institut was founded for the purpose of analysing and monitoring the solar power modules. The Fraunhofer institut has also reviewed several individual solar power modules on behalf of SCHOTT and has released the results on the internet.
The "Fraunhofer Institut" for solar energy systems is monitoring the solar power plants in the Environmental Tariff. In addition, they are analyzing several power plants for SCHOTT Solar and release the results in the internet.
