Daidalos is a ray tracing framework developed for the purpose of simulating the optical properties of photovoltaic (PV) modules in their environment. It enables many different applications across seven orders of magnitude in size from ray tracing of building facades to ray tracing of solar cell texture elements. Daidalos-Cloud is the online version of Daidalos. Using the Daidalos-Cloud web interface, you can adjust the PV module simulation properties via 79 parameters and download the results for your own use.
