8 DK 177168 B1
1. Fremgangsmåde til diagnosticering af fejl i et solcellesystem indeholdende flere solcellemoduler, hvilken fremgangsmåde omfatter trinnene udført om dagen og 5 potentielt også i mørke: i) påføring af en elektrisk BIAS i form af et DC signal over solcellemodulerne med en potentiostat, i området fra -1000 til +1000 volt DC i potentiostatisk mode eller 5-10 ampere i galvanostatisk mode; ii) foruden jævnspændingen fra trin i) påføring af en vekselstrømsspænding, mens der 10 scannes i et frekvensområde fra 1 Hz til 10 MHz med en AC amplitude på op til 1000 volt AC; iii) sammenligne impedans-spektret med et kontrol-impedans-spektrum optaget fra et intakt solcelleanlæg eller optaget tidligere i solcellesystemet, og iv) at diagnosticere fejl i henhold til følgende skema: automatisk overføre de målte data til en central database, hvor en computer tilpasser en fysisk model til dataene og lagrer parametrene udledt fra denne modelleringsrutine.
2. Fremgangsmåde ifølge krav 1, hvor afvigelser i det optagede spektrum i frekvensområdet 1Hz-10MHz detekteres automatisk af et computerprogram og anvendes til yderligere analyse af systemet.
3. Fremgangsmåde ifølge krav 1, hvor den fysiske model er baseret på et ækvivalent solcelle kredsløb, som indeholder kredsløbselementer relevante for det karakteriserede system. 25 DK 177168 B1 A" A' —/ — B _/_ A _ C Figure 1 DK 177168 B1 B Figure 2
