Paper Abstract

We present performance and cost data on a distributed concentrated photovoltaic (CPV) system that is commercially available in 2008 and will break the long pursued $2/W price barrier. This technology was developed from an existing product platform used originally for solar fiber optic lighting applications and includes a novel segmented plastic mirror that concentrates sunlight into a dense-array CPV module at 600 suns. The design's segmented plastic mirror and high-precision, low-cost tracking unit are presented as a flexible hardware platform evolved in response to market pressure over the past two years and suitable for multiple applications being developed in the concentrating solar field. To illustrate the economic benefits of this solar collection platform, the specific costs related to COGS and installation activities associated with a commercial CPV product available in 2008 are presented.
