Assessing Photovoltaic System Performance under Varied Weather Conditions: A Detailed Examination

Abstract

Cross-referencing information from the National Renewable Energy Laboratory's PV Fleet database, which tracks continuous PV performance, with facts from the National Oceanic and Atmospheric Administration's extensive weather database allowed researchers to take a look at how excessive climate affects Photovoltaic (PV) performance. Direct weather-associated outcomes were discovered at one hundred seventy installations during the examination. There is a median loss of just 1% of annual production because of these intense weather occurrences. On the other hand, it was discovered that the tail of flooding and sturdy wind occurrences became exceptionally lengthy, attaining 60% loss, indicating that those isolated occasions can be a massive concern to PV structures. By evaluating the overall Performance Loss Rate (PLR) earlier than and after robust wind occurrences over ninety km/h, we discovered a statistically good-sized increase in PLR and the fast-time period results of output loss because of outages. Likewise, PLR elevated in reaction to hail occasions for hail diameters of 25 mm and more excellent, suggesting that PV modules must go through a more thorough hail checking out. Extremely excessive snow hundreds may doubtlessly bring about better PLRs despite additional data being needed to determine the effect entirely. These effects spotlight the giant quick- and long-term-period threat of intense weather activities.
