This paper describes recent developments in the creation of sound-making instruments and devices powered by photovoltaic (PV) technologies. With the rise of more efficient PV products in diverse packages, the possibilities for creating solar-powered musical instruments, sound installations, and loudspeakers are becoming increasingly realizable. This paper surveys past and recent developments in this area, including several projects by the , , author, and demonstrates how the use of PV technologies can influence the creative process in unique ways. In addition, this paper discusses how solar sound arts can enhance the aesthetic direction taken by recent work in soundscape studies and acoustic ecology. Finally, this paper will point towards future directions and possibilities as PV technologies continue to evolve and improve in terms of performance, and become more affordable.
