 This paper examines the environmental impact of four different types of solar panels, single crystal silicon, SCC, multi-crystalline silicon, MCC, cadmium telluride, CDTE, and copper indium gallium disilennide, CIGS. The authors found that CDTE panels have the lowest environmental impact due to its higher efficiency and lower cost, compared to other technologies. Additionally, they found that one-axis tracking installations can reduce the environmental impact of solar panels by about 10%.
