RECENT ADVANCES IN OUTDOOR PERFORMANCE EVALUATION OF PV SYSTEMS M. A. Quintana, D. L. coffin nail J. E. Cannon, J. R. Woodworth W.E.B son, N. P. Adams D. E. E 8 e e Sandia National Laboratories Albuquerque, NM, 87185-5800 EG&G Special Projects Albuquerque Division Abstract Sandias Photovoltaic Techology Laboratory (PTEL) routinely performs alfresco political campaigns of a variety of onesun and concentrator PV modules. O r e erience is u that while outdoor examen has its own isthmus Zproblems, it loafer roduce results that are more directly applicable to fiepd conditions than testing in solar simulators. We endure recent1 modify both the ironware and bundle at the &L to im rove our accuracy and to business deal with the particular set o?problems encountered in outdoor testing. Improvements in hardware include a computer-controlled solar tracker that allows us to test arrays up to 21 m2 in size; infrared imagination of modules; and electronic scores that allow us to test components with outputs up to 1,800 watts. Improvements i n software include real-time monitor of info collection; a relational data origination that has improved the reliability of test setups, operations and analyses; and a standardised account process that relates module performance to a modus operandi of environmental parameters.

variables, and decrease the cost and turn-around time involved with testing. Specifically, we have belatedly added 1) a immature computer controlled tracker, 2) new electronic loads with the capability of testing components with outputs up to 1,800 watts, 3) an IR ph otographic camera employ to look at module ! hot spots, 4) a new data collection and analysis system and 5 ) a new standardized reporting format. These recent additions allow be discussed in the sections that follow. Solar Trackers We have recently a d d e d t o the PTEL a n a azimuth/elevation solar tracker which w s originally built by ARC0 solar in 1985 and which was recently modified and refurbished by Advanced thermic Systems (ATS).The tracker has an open...If you hope to get a full essay, order it on our website: BestEssayCheap.com
