Abstract/Summary:

---

A reliable operation of an indoor photovoltaic (ipv) device requires the knowledge of the expected irradiance. Available data on indoor irradiance, refer to single measurements and/or to values using the photometric unit Lux. This study evaluates the performance of luxmeters depending on the light source, the use of the ray tracing programs Radiance [1] and DAYSIM [2] in ipv-design, and radiometric measurement methods for low intensities to validate the simulation results obtained. The authors present flexible and cost effective methods for ipv-designers to determine reliable radiometric values of indoor irradiance.
