The Fraunhofer Institute for Solar Energy Systems (ISE) has performed a recent ‘Power Check’ study, which has found that Solar-Fabrik generates high annual energy yields. Fraunhofer ISE tested the data of 115 of the company’s solar power systems throughout Germany and assessed each one by location.
Analysing the supply statements of the respective power supply companies formed the basis for the study; system performance varied from 2-10kW. An evaluation was made of the data from 2005 through 2008.
According to the experts, “The photovoltaic systems under study generated, on average, yields of almost 1000kWh/kWp. The extremely high yield values are a direct result of the very good irradiation conditions over the last several years and the obvious improvement in system efficiency.”
Some 20% of the systems generated yields superior to 1,000kWh/kW output, and an additional 20% produced yields of more than 1,050 kWh/kWp. The best systems generated over 1,100kWh/kWp in each of the four years, according to the study.
“The results once again confirm that our superior quality standards directly benefit our customers,” explained Karl-Heinz Dernbecher, sales director at Solar-Fabrik. “Our quality management and the permanent continuous development of our manufacturing techology provide our customers with a safe and reliable environment for their investments.”
Fraunhofer ISE concludes, “The Power Check demonstrates that systems with Solar-Fabrik components […] provide very good results overall. Such a result is only possible using premium modules and inverters, having a good system design as well as a proper installation and a nearly fault-free operation.”
