Amandla eepaneli ze-photovoltaic zelanga zidla ngokuchazwa kwii-watts (W), umzekelo, iphaneli ye-photovoltaic ye-100-watt inokuvelisa i-watts eyi-100 yombane.Ubungakanani kunye namandla eepaneli ze-photovoltaic zinokukhethwa ngokweemfuno, kwaye zinokuba zincinci, kwizicelo zokuhlala kunye nezorhwebo, okanye ezinkulu, kwizityalo ezinkulu zamandla elanga.
