CloseThis event has ended. Every year, the European Solar Test Installation (ESTI) laboratories of the Joint Research Centre (JRC) organise the International Spectroradiometer Intercomparison (ISRC). The event consist of a week-long uninterrupted measurements of solar and artificial radiation. The activity is open to all interested participants, who will have the opportunity to measure their equipment's performance with reference instruments. Participants will be given access to the entire dataset of spectra acquired during the measurement, including the reference data.

All other expenses (travel, accommodation etc.) are covered by participants. Description The performance of the participating spectroradiometers will be assessed against a set of calibrated ESTI spectroradiometers by measuring:natural sunlight in clear sky conditionsartificial light using the steady-state large area Apollo solar simulatorFEL standard lampsSeveral performance statistics indicators will be calculated, with focus on the relative spectral content in different spectral bands. The results will be published by the JRC in an official report. All the participants will have access to the entire dataset of spectra acquired by the group, including the reference data. Several other prototypes and custom sensors are also eligible for participation and the report foresees a dedicated section for these instruments if they are not directly comparable with reference instruments.Launched in 2011, the first ISRC edition focused primarily on photovoltaic (PV) research and application. Over the years, the range of interested participants has gradually differentiated, encompassing not only laboratories in the PV field, but also space agencies, national metrological institutes (NMI), universities, research groups and manufacturers of measurement equipment operating in the fields of climatology and meteorology.6 FEBRUARY 2025ISRC 2025 - Invitation and instructions Contacts General contact Diego Pavanello Technical organisation NameDiego PavanelloEmaildiego [dot] pavanelloec [dot] europa [dot] euPhone number+39 0332 78 6449 Energy Efficiency & Renewables Unit Administrative queries NameEnergy Efficiency & Renewables UnitEmailJRC-C2-SECRETARIATec [dot] europa [dot] eu
