PVSOL: Fully instrumented inverters in continuous system performance test For FY 2005, the project had three separate sub- tasks: System Performance Testing and Modeling, Inverter Performance Characterization, and Advanced System Concepts. 2.1 System Performance Testing and Modeling This task was focused on developing, validating, and documenting improved system and PV array testing, modeling, and monitoring techniques in direct collaboration with industry, the National Renewable Energy Laboratory (NREL), and also this year with NIST. Specific objectives of the task are to: • Develop array testing, data analysis, and performance-modeling procedures that are accurate and able to be practically implemented for c-Si, thin-film, and concentrator PV. Array Pmp (calc) • Assist industry in developing performance indices and low-cost monitoring methods for systems. • Apply testing/modeling methods, providing integrators and manufacturers with detailed inverter and array performance data for current technology systems. 94 92 90 88 86 84 82 255 Vdc 320 Vdc 405 Vdc 485 Vdc 2000 2500 3000 improved • Evaluate the field-aging characteristics of arrays and inverters that affect performance, reliability, and safety. 79 Fig. 4.

Typical system performance on cloudy day 2.2 Inverter Performance Characterization Under this task, we conducted comprehensive inverter testing to aid inverter development, benchmark performance and utility compatibility of commercial inverters, identify degradation/failure mechanisms during long-term field aging, and provide performance parameters needed for system energy modeling. Extensive laboratory equipment and expertise shared with SNL’s Distributed Energy Technology Laboratory (DETL) are used to support this effort. This activity addresses the “Inverter Testing and Industry Support” section of the MYPP. For the inverter long-term aging activity, multiple sites (SNL, FSEC, and SWTDI) were established and instrumented to obtain consistent sets of performance data under different environmental conditions. A test protocol was developed for the comprehensive initial baseline tests conducted at SNL. After field aging, the baseline tests will be repeated at SNL on nominally an annual basis to identify failures and degradation rates.
