Geospatial analysis of the energy yield and environmental footprint of different photovoltaic module technologies

摘要: Abstract The majority of currently installed photovoltaic (PV) systems are based on mono- and polycrystalline silicon PV modules. Manufacturers competing technologies often argue that due to the characteristics their technologies, modules able achieve higher annual energy yield, a smaller effect temperature module performance and/or better at low light intensities. While these benefits have been confirmed in local studies many times, there is still limited insight as locations which particular technology actually performs best. In this study we analysed large set modules, irradiance time series were taken from satellite measurements. Using data, combining it with model, made geospatial analysis yield different types We aim make investigated spatially explicit, allowing system installers choose best type for every location investigated. Our results show geographical variety terms but also relative or ratio. some clearly exhibit decrease ratio where they operate temperatures, much smaller. As result variation performance, environmental footprint shows variations. However, even general lower compared fossil fuel electricity generation.
