Vanliga frågor
-
Vad är solcellsenergilagring?
Fotovoltaisk energilagring är processen att lagra solenergi som genereras av solcellspaneler för senare användning.
-
Hur fungerar solcellsenergilagring?
Det fungerar genom att omvandla solljus till elektricitet, som sedan lagras i batterier för användning när solen inte skiner.
-
Vilka är fördelarna med solcellsenergilagring?
Fördelarna inkluderar energioberoende, kostnadsbesparingar och minskat koldioxidavtryck.
-
Vilka typer av batterier används vid lagring av solceller?
Vanliga typer inkluderar litiumjon-, bly-syra- och flödesbatterier.
-
Hur länge håller solcellsenergilagringssystem?
De håller vanligtvis mellan 10 till 15 år, beroende på användning och underhåll.
-
Kan solcellsenergilagring användas för reservkraft?
Ja, den kan ge reservkraft under avbrott eller nödsituationer.
