SLF researcher<\/a> Anja Mödl investigates how snow-covered terrain reflects sunlight. Her findings should make photovoltaic systems more efficient. The measurements take place in Meierhoftälli near Davos at around 2,400 meters above sea level.<\/p>\n\n\n\n\n\n

The researcher uses sensors to examine the sunlight reflected by the snow cover. According to the press release<\/a>, the majority of sunlight is reflected by the snow in the direction of incidence. Sunlight is thus largely reflected in the direction of other mountain slopes.<\/p>\n\n\n\n\n\n

The snow surface reflects different wavelengths to different degrees. The intensity of certain wavelengths thus becomes stronger over time than in the originally incident light. Mödl is investigating how spectra differ at different locations.<\/p>\n\n\n\n\n\n

The measurements should enable photovoltaic systems to generate electricity even more effectively. Optimally positioned systems should then also be able to use the light reflected from neighboring slopes.<\/p>\n\n\n\n\n\n

The sensors measure wavelengths between 340 and 2500 nanometers. Photovoltaics only use the range between 500 and 1100 nanometers. According to Mödl, the larger spectrum makes it possible to gain further insights into rock warming and snow melting.<\/p>\n\n\n\n\n\n

Measurements are also planned for the coming season. “In order to make a well-founded statement, I need to record data under different conditions,” says the researcher.<\/p>\n\n","protected":false},"excerpt":{"rendered":"
