SolFocustrade is developing two generations of photovoltaic concentrator systems, both based on reflective Cassegrain-like architectures. Generation 1 is being readied for manufacturing, and is poised for roll out to test fields this year. Generation 2, a solid dielectric system, is under joint development by SolFocus and PARC, with prototype components under evaluation. The status of generation 1 is presented for background, and we discuss technical aspects of generation 2
