in referred journals and in conference proceedings in his areas of the research interests. He has also been PI or Co-PI for various research projects United States and abroad in power systems analysis and protection, load and energy demand forecasting, renewable energy, microgrids, wave and turbulence, radar and remote sensing, instrumentation, atmosphere physics, electromagnetic compat- ibility, and engineering education.Prof. Lucian Ionel Cioca, Lucian Blaga University of Sibiu Lucian Ionel CIOCA received the M.Sc. in Machine Tools (1993) and B.Sc. in Occupational Safety, Health and Work Relations Management (2010). In 2002, he becomes Dr. Eng. (Ph.D degree) of Pet- rosani University, Romania and now he is

of 14 panels. The 14 panels arewired in the series/parallel configuration shown in Figure 3 to stay below the current and voltagelimits of the disconnects and the inverter. The inverter provides its own DC and AC disconnectsand then the wire is routed to a distribution panel within the building. Figure 3. Schematic of solar photovoltaic array.The basic construction of the photovoltaic array was relatively easy. A pre-fabricated trusssystem was mounted to a steel frame on the roof of the building. The panels were then attachedto the truss. As shown in Figure 4, much of this work was accomplished by students whovolunteered to assist. This do-it-yourself installation was a great learning experience but it didtake a

on this breaker. Thispaper will discuss the problems encountered running these tests with undergraduates, includingsafety and power concerns. It will also discuss the student’s interactions and their impressions ofthe testing; and look at methods to evaluate how well they learned the testing methods and thecircuit breaker operational concepts. The travel time test requires that both 120 V ac (for thecompressor) and 125 V dc (for the controls) be provided to the breaker. On the breaker tested, alarge spring is used to open the interrupters, while a pneumatic system is used to close thebreaker. A Doble TDR900 is used to perform the test. This test instrument has inputs for: 1) thelinear transducer that measures the movement of the operating

2008 2009 2010 2011 2012 2013 2014 2015 2016Soiling is a significant issue thataffects the power output of solar panels [3]. The mechanism of this effect is easy to appreciate –if panels get dirty, the dirt on the top of the panel glazing reduces the transmission of light to thesilicon semiconductor, and as a result photocurrent is greatly reduced. The effect is similar tohaving the panels shaded by a tree or other such obstruction. What many people find surprisingis that even for systems with annual cleaning regimens, reductions in panel performance due tosoiling frequently are found to be as much as 10-15% loss of electrical output. In extreme caseswhere panels are not inspected/maintained, the surface may become completely opaque withgrime
