Kev hloov dua siab tshiab ntawm photovoltaic fais fab tuag yog tsawg heev, crystalline silicon photovoltaic cell conversion efficiency yog 13% ~ 17 feem pua, amorphous silicon hnub ci cell conversion efficiency tsuas yog 6% ~ 8 feem pua. 2 cuam tshuam los ntawm kev nyab xeeb, hnub ntev daus, hnub huab cua, huab cua hloov pauv yuav cuam tshuam rau lub zog hluav taws xob photovoltaic, lub zog photovoltaictiam lub teeb ntauwdefficiency yuav txo tau ntau.
Vim lub hnub ci zog tsawg tsawg, ib leeg nrog photovoltaic cheeb tsam yuav loj heev, tib lub zog, photovoltaic zog tsim dua cua-lub teeb complementary yuav siv sij hawm ntau qhov chaw yog loj, lub ntim loj heev load nce, yog unfavorable rau kev nyab xeeb.
