We determine the theoretical maximum concentration factors for different definitions of the factor for two-dimensional and three-dimensional solar concentrators that are valid for any source with nonuniform intensity distribution. Results are obtained starting from those derived by Winston [J. Opt. Soc. Am. 60, 245 (1970)] for Lambertian sources. In particular, maximum concentration factors for three models of the solar-disk intensity distribution are calculated.
