“…• mirror facet nominal reflectance, 0.95 [11]; • mirror facet cleanliness factor, 0.95 (measured with a reflectometer); • intercept factor of the primary concentrator assembly, 0.95; this value takes into account the optical error of the facets, the facet edging error of the facets in the rows, and the error associated with the tracking system (estimated from [18][19][20]); • angle of incidence modifier calculated for the time at which the measurement was made, 0.99 [15];…”

Linear Fresnel solar collectors are a promising and emerging solution to contribute to renewable heat supply in industrial processes with thermal energy demand in the medium temperature range (<250 °C). An innovative linear Fresnel collector (LFC) prototype has been designed, patented, and built at the Plataforma Solar de Almería (PSA), Spain. This work presents the applied methodology, experimental device, and results obtained in the measurement of the flux density of concentrated solar radiation in the focal plane of the solar collector. The experimental results confirm that an average flux density of (9.8 ± 0.6) kW/m2 was obtained with a direct normal solar irradiance of (870 ± 10) W/m2 in tests performed in May 2002, which is a result similar to that obtained in optical simulations of the system.
