We propose an analytical methodology for estimation of the optimal PV panel tilt based on calculation of the sun`s position and the application of a clear-sky solar irradiance model. Our methodology outputs three angles referencing a geolocation and the moment of interest: the incidence angle q, the sun altitude a and the sun azimuth z. The irradiance model estimates the solar irradiation at a geolocation that can be used for PV conversion estimation based on specified tilt ß. The moment PV power is used for calculation of the daily energy production, and the optimal ß is identified in the tilt range of 0° to 90°. Seasonal division of the year is performed, and optimal seasonal tilt is estimated based on the maximally produced seasonal energy, tested with every corresponding ß. The methodology is tested on four typical seasonal models - 12 months, 4 three-month quarters, 2 half-year seasons and a single optimal annual fixed ß The preliminary simulations produced promising results consistent with the practical engineering implementations</dc:description><dc:description xml:lang="sl">Nagib PV-panela in sledenje soncu sta ključna vidika učinkovitosti PV-pretvorbe. Predlagamo analitično metodologijo za oceno optimalnega nagiba fotonapetostne plošče na podlagi izračuna položaja sonca in uporabe modela sončnega sevanja pri jasnem nebu. Naša metodologija prikaže tri kote, ki se nanašajo na geolokacijo in trenutek opazovanja: vpadni kot q, višinski kot sonca a in azimut sonca z. Model obsevanja ocenjuje sončno sevanje na geolokaciji, ki se lahko uporabi za oceno pretvorbe PV na podlagi določenega nagiba ß. To je trenutek, ko se PV moč uporabi za izračun dnevne proizvodnje energije, optimalni ß pa se določi v območju nagiba od 0° do 90°. Izvede se sezonska delitev leta in optimalni sezonski nagib se oceni na podlagi največje proizvedene sezonske energije, testirane z vsakim ustreznim ß Metodologija je preizkušena na štirih tipičnih sezonskih modelih ? 12 mesecih, štirih trimesečnih kvartalih, dveh polletnih sezonah in enem optimalnem letnem fiksnem ß. Predhodne simulacije dajejo obetavne rezultate, skladne s praktičnimi inženirskimi izvedbami</dc:description><edm:type>TEXT</edm:type><dc:type xml:lang="sl">znanstveno časopisje</dc:type><dc:type xml:lang="en">journals</dc:type><dc:type rdf:resource="http://www.wikidata.org/entity/Q361785" /></edm:ProvidedCHO><ore:Aggregation rdf:about="http://www.dlib.si/?URN=URN:NBN:SI:DOC-FT4GVIXV"><edm:aggregatedCHO rdf:resource="URN:NBN:SI:DOC-FT4GVIXV" /><edm:isShownBy rdf:resource="http://www.dlib.si/stream/URN:NBN:SI:DOC-FT4GVIXV/4f30715b-da97-4af7-9581-7b5501a43c40/PDF" /><edm:rights rdf:resource="http://rightsstatements.org/vocab/InC/1.0/" /><edm:provider>Slovenian National E-content Aggregator</edm:provider><edm:intermediateProvider xml:lang="en">National and University Library of Slovenia</edm:intermediateProvider><edm:dataProvider xml:lang="sl">Univerza v Mariboru, Fakulteta za energetiko</edm:dataProvider><edm:object rdf:resource="http://www.dlib.si/streamdb/URN:NBN:SI:DOC-FT4GVIXV/maxi/edm" /><edm:isShownAt rdf:resource="http://www.dlib.si/details/URN:NBN:SI:DOC-FT4GVIXV" /></ore:Aggregation></rdf:RDF>
