Apraksts<\/strong><\/h3>\n

Atkar\u012bb\u0101 no fotovolt\u0101\u017eas sist\u0113mas pieg\u0101d\u0101t\u0101s ener\u0123ijas daudzuma var b\u016bt gan viet\u0113j\u0101s maz\u0101s saules \nelektrostacijas, gan liel\u0101kas saules elektrostacijas. Divi galvenie komponenti, kas ir nepiecie\u0161ami \nfotovolt\u0101\u017eas sist\u0113m\u0101m, ir saules pane\u013cu modu\u013ci un invertori.<\/p>\n

M\u0101jsaimniec\u012bb\u0101s saules modu\u013cus parasti savieno s\u0113rijveid\u0101 vai paral\u0113li uz m\u0101jas jumta. Pils\u0113tvid\u0113 tos \nvar atrast uz jumtiem virs autost\u0101vviet\u0101m vai uz zemes sl\u0113gt\u0101s teritorij\u0101s. No tehnolo\u0123isk\u0101 viedok\u013ca ir \nda\u017e\u0101di saules pane\u013cu veidi: pl\u0101n\u0101s pl\u0113ves tehnolo\u0123ijas, multikrist\u0101liskie vai monokrist\u0101liskie sil\u012bcija \npane\u013ci, kuru vid\u0113jais kalpo\u0161anas laiks ir 25-30 gadi.<\/p>\n

Invertori ir nepiecie\u0161ami l\u012bdzstr\u0101vas p\u0101rveido\u0161anai mai\u0146str\u0101v\u0101 un sprieguma un frekvences \nregul\u0113\u0161anai. Past\u0101v divi galvenie invertoru veidi - vienf\u0101zes un tr\u012bsf\u0101\u017eu invertori, kurus izmanto atkar\u012bb\u0101 \nno PV sist\u0113mas pieg\u0101d\u0101t\u0101s jaudas apjoma.<\/p>\n
