The principals of REhnu - all associates of the University of Arizonas Steward Observatory Mirror Lab - are leveraging on decades of work in opto-mechanical design and production of mirrors and mounts for the worlds largest optical telescopes - anchoring REhnus business model for developing solar generators that, when produced in volume, will generate electrical energy at a cost competitive with fossil-fuel generation. The firmis organized around manufacture and commercializationof solar concentrating technology using large glass mirrors to focus sunlight onto photovoltaic cells to produce solar electricity. Developed through a series of prototypes, the technology for REhnus concentrating photovoltaic generators has evolved to become the firm's standard, production-ready mirror module, now being manufactured for sale in dual-axis trackers. Anchored in substantial funding from various sources through the years, REhnu (pronounced renew) derives its name from the formula E=h? or E=hnu which relates the energy E of a photon to the photons frequency, given by the Greek letter ?, or nu, and Plancks constant h. The R preceding E in our name signifies the REnewable nature of energy derived from light.
