FIELD PERFORMANCE MEASUREMENTS OF NEW AND TRADITIONAL PV TECHNOLOGIES

摘要

At the Tucson Electric Power (TEP) Solar Test Yard, over 20 different grid-connected PV systems are being tested. The systems include flat-plate PV like Sunpower, Sharp, Uni-solar, Sanyo, Shell, Evergreen, and Petra Solar. Performance of several of these systems has been recorded since 2003. Since then, concentrating PV modules have been also deployed at the TEP test yard, including systems from Solyndra, Prism Solar Technologies Inc., Skyline Inc., Semprius Inc, and Green Volts Inc. We discuss recent upgrades to the TEP Solar Test Yard and how these upgrades have improved our measurements. We present preliminary measurements of final yields, performance ratios, temperature de-ratings and degradation rates for the period 2009-2011. Measured final yields are compared to predictions from PVwatts and PVsyst.
