• SWRES: Performed thin-film performance testing on U.S.-manufactured CdTe modules in service in hot/humid climate of Morelos, Mexico. • SERES: A meeting of the IEA Photovoltaic Power Systems Program Task 2 was held at FSEC with representatives from DOE, SWRES, SERES, and several of the participating countries. • SERES: In January, FSEC welcomed its new director, Dr. James Fenton, formerly with the University of Connecticut. • SERES: About 100 people participated in a PV dealer’s conference sponsored by SunWize Technologies and hosted by FSEC. • SERES: Performance of a monitored system in Homestead, Florida, using a Kyocera KC120 PV array and two SMA 2500U inverters, underwent significant performance degradation of >25% during a 4-month period, ultimately causing inverters to drop off-line for extended periods. An investigation found array voltage problems, and the manufacturer was involved in corrective actions. Other instances of the same problem have been identified. • SERES: FSEC staff conducted acceptance testing on a number of PV and solar thermal installations in the U.S. Virgin Islands under a separate contract to the Virgin Islands Energy Office. • SERES: SERES and SNL staff participated in the National Rural Electric Cooperative Association’s New and Emerging Technologies Conference in Tampa, Florida. • SERES: FSEC’s PV installer and code-official training programs were recognized by the Florida Department of Business and Professional Regulation for continuing education units required for contractors and code officials. • SERES: Major construction activities were completed on a new facility at FSEC for PV inverter and systems testing, and PV and distributed-generation applications training. • SERES: FSEC staff conducted two PV installer workshops: May 2–6 at FSEC and May 23–27 at the Portland Electrical JATC, Lewiston, Maine. • SERES: Jim Dunlop agreed to serve as technical committee chair for the North American Board of Certified Energy Practitioners, having previously served in this capacity through September 2003. The • • • • • • • • position became vacant as a result of the death of Mark Fitzgerald. SERES: Jim Dunlop assisted a Florida contractor in inspecting a residential PV system suspected of underperforming. Investigations showed that the Photowatt modules, rated at 165 watts, were 20 watts lower (which was indicated by a small notation on the back surface of the modules, not on the nameplate). This single relatively trivial example demonstrates the need for module- performance rating standards to protect consumers, especially for residential markets. SERES: GE Solar contacted FSEC about field-testing its new interactive inverter, which is still under development and has undergone significant testing at SNL. Funding the cost of this testing is an unresolved issue. SERES: FSEC hosted a meeting at the American Solar Energy Society (ASES)/ International Solar Energy Society (ISES) Conference to address PV product certification in the United States. Twenty-four individuals attended this meeting, including representatives from laboratories, states, and other groups involved in developing standards and evaluating and certifying PV systems and equipment SWRES: Performed PV system field tests of on-grid and off-grid PV systems: Tucson, Arizona; Albuquerque, Las Cruces, and Farmington New Mexico; Sacramento, California; Yellowstone National Park, Wyoming; Phoenix, Arizona; Amarillo, Texas; and Morelos, Mexico. SERES: American Association of Laboratory Accreditation (A2LA) staff completed a surveillance audit of FSEC PV and solar thermal testing laboratories in accordance with ISO 17025. SWRES: Participated in the UL 1741 (inverters) and 1703 (modules) Standards Technical Panels; participated in the NABCEP Exam Committee. SERES: FSEC staff met with Sharp Solar staff regarding a planned PV project involving 500 homes in Naples, Florida, with Centex homes. SERES: FSEC staff met with Mark Dougherty, Solar Program manager for Long Island Power Authority (LIPA). The discussion involved areas of joint interest to LIPA, FSEC, and SERES, including an upcoming LIPA solicitation for PV system evaluation and monitoring services.
