Abstract
Doktorska disertacija obravnava delovanje in staranje fotonapetostnih (PV) modulov in fotonapetostnih sistemov, ki delujejo v različnih podnebnih razmerah po vsem svetu. Glavni poudarek je na razvoju novih pristopov za ocenjevanje zmogljivosti in izgub modulov in sistemov. Predstavljenih in pojasnjenih je več novih pristopov, ki temeljijo na zajetih podatkih, kot so metoda tipičnih dnevnih profilov (TDP), Köppen-Geiger-Photovoltaic (KGPV) klimatska klasifikacijska shema in ocena donosa zaradi podnebnih sprememb (CCYA). Disertacija obdela metode vrednotenja zmogljivosti in izgub pri proizvodnji električne energije iz fotonapetostnih modulov in sistemov. Pri tem se pridobivajo, združujejo, čistijo in obdelujejo raznolike in velike količine podatkov iz raziskovalnih ustanov, fotovoltaičnih elektrarn, podnebnih modelov in satelitskih podatkov, ki omogočajo dragocen vpogled v dejansko stanje in trende. Podatkovni viri so razvrščeni v geografske informacijske sisteme (GIS) in časovne vrste, pri čemer izkoriščamo oba načina ločeno in skupaj. V okviru disertacije je razvoj pristopov z ustreznim izborom podatkovnih virov, povezanih s fotovoltaiko, omogočil predstavitev globalnih zemljevidov za določitev najboljših področij za proizvodnjo električne energije in opredelitev tveganih lokacij v luči povečane stopnje degradacije, tudi na račun umazanije in zasneževanja. V zadnjem sklopu so ključni kazalniki učinkovitosti, kot sta razmerje učinkovitosti in stopnja degradacije, analizirani, modelirani in ovrednoteni na časovni projekciji do leta 2100 in na globalni prostorski ravni, kar omogoča oceno podnebnih vplivov na podlagi preteklih podatkov in različnih scenarijev podnebnih sprememb.

Title:MODELLING AND WORLDWIDE ASSESSMENT OF PERFORMANCE AND AGING OF PHOTOVOLTAIC MODULES AND SYSTEMS
Abstract:
This doctoral dissertation discusses the performance and ageing of PV modules and PV systems operating in different climates worldwide. The primary focus is developing new techniques for assessing the gain and loss factors of PV technologies. Several novel data-driven techniques, such as the Typical Daily Profiles (TDP) method, the Köppen-Geiger-Photovoltaic (KGPV) climate classification scheme, and the Climate Change Yield Assessment (CCYA), are introduced and explained with interesting case studies. The basis of the gain and loss factors of energy production based on typical PV technologies are discussed. Here, diverse and large amounts of data from research facilities, PV power plants, climate models, and satellite-based information are retrieved, combined, cleaned, and processed, bringing valuable insights to the PV industry. The research categorizes data resources into geographical information systems (GIS) and single-time-series, taking advantage of both ways separately and combined. In the frame of this thesis, the selection of relevant PV related data sources and methodologies has allowed the presentation of eye-catching global maps to identify the best places for energy production and the identification of risky locations in terms of degradation, soiling and snow shading. Finally, key performance indicators, such as performance ratio and degradation rates, are analyzed, modelled, and evaluated on a temporal and spatial scale, being able to assess climatic impacts on historical data and under different climate change scenarios.

Keywords:PV module, PV systems, performance, degradation rate, climate zone, GIS, O&M
