Ngesu likazwelonke kanye nokusekelwa kwenqubomgomo yemithombo yamandla emisha, umqondo wamandla aluhlaza usugxile kakhulu ezingqondweni zabantu. Intuthuko yezobuchwepheshe kanye nokwehla kwezindleko zokufaka kuholele ekwandeni kwenani labantu abafaka izinhlelo ze-PV zelanga ophahleni lwabo. Ngaphandle kwezinzuzo zemvelo, abaningi bakhathazeke kakhulu ngenzuzo yezezimali yezinhlelo ze-PV zekhaya. Le ngxoxo igxile ezintweni ezithonya imali engenayo evela ezitshalweni zamandla ze-PV ezisatshalaliswa emakhaya.
Abaninikhaya abaningi abanezinhlelo ze-PV babika ukuthi ukukhiqizwa kwabo kwamandla akusebenzanga kahle njengoba bekulindelekile, ngokuvamile ngenxa yokuphambuka ekhoneni lokuthambekela elifanele. Isibonelo, eShanghai (latitude degrees 31), uma amaphaneli e-PV efakwa ekhoneni lama-degree angu-23 esikhundleni sama-degree angu-31 afanele, ingabe lokhu kunciphisa kakhulu ukusebenza kahle?
Inganekwane ye-Angle Ehamba Kahle Kakhulu
I-angle ebizwa ngokuthi i-optimal tilt angle, ekhulisa ukwamukelwa kwemisebe yelanga, ithinta ukusebenza kahle kwe-PV. Kodwa-ke, empeleni, akuyona yodwa into enqumayo. I-angle engcono kakhulu iyahlukahluka ngokuguquguqukayo futhi izindawo zokufaka ziyahlukahluka kakhulu. Ngisho noma ifakwe e-engeli enhle kakhulu, imali engenayo ingahluka.
Nakuba i-angle yokuthambekela ithinta ukusebenza kahle, umthelela wayo uvame ukuba mncane. Izinkampani zokufaka zivame ukukhetha i-engeli efanelekile ngokusekelwe ekucabangeni okuphelele. Isibonelo, eShanghai (ama-degree angu-31 enyakatho ye-latitude), ukulingisa kubonisa ukulahleka kokusebenza kahle kuma-engeli ahlukahlukene: ama-degree angu-5 (3.6%), ama-degree angu-15 (0.8%), ama-degree angu-25 (0%), ama-degree angu-30 (0.5%), kanye nama-degree angu-40 (2.7%). Ngakho-ke, ama-engeli aphakathi kwama-degree angu-15 no-35 ayamukeleka ngokuvamile. Ukubeka phambili inzuzo encane yokusebenza kahle ngezindleko zendawo ebalulekile kunganciphisa izinzuzo eziphelele.
Izici Eziyinhloko Ezithinta Imali Engenayo
Njengoba umthelela we-tilt angle uncane, ezinye izici zidlala indima ebaluleke kakhulu ekukhiqizeni imali engenayo.
1. Ukuphepha
Ukuphepha kubaluleke kakhulu; ngaphandle kwakho, ukuxoxa ngemali engenayo akusizi ngalutho. Izinhlelo ze-PV zasekhaya zingafakwa ophahleni olusukela ezitezi ezimbili kuya kwezingamashumi amathathu ukuphakama. Umklamo ongemuhle ungaholela ezingozini ezinkulu zokuphepha.
Izinto Okufanele Uzicabangele Ngomklamo: Ukuphishekela i-engeli yokuthambekela engcono kakhulu kungadinga ama-bracket aphezulu, okufaka izidingo ezinkulu zesakhiwo ophahleni. Ukwehluleka kwesakhiwo akuvamile.
Ukugcinwa: Ukufinyelela okufanele ekugcinweni kubalulekile. Ezinye izinto zimboza lonke uphahla, okwenza ukulungiswa kube nzima. Ukuhlanza njalo kubalulekile, njengoba ngisho nezithiyo ezincane njengendle yezinyoni zingathinta kakhulu ukusebenza.
2. Ukufiphaza
Umbono ongalungile wokuthi ukufiphaza okuncane ngeke kukhathaleke awulungile. Ngisho nokufiphaza okuncane kungabangela ukulahlekelwa ukusebenza kahle okungu-10% noma kulimaze uhlelo lwe-PV, okuthinta ngqo imali engenayo.
3. Ukuqondiswa
Izindlu eziningi zibheke enyakatho-eningizimu, kodwa eziningi zibheke empumalanga-entshonalanga, futhi uphahla olunezinhlangothi eziningi luvamile. Ukuze uthole imali engenayo engcono, gwema ukufaka amaphaneli ezinhlangothini zasempumalanga, entshonalanga, noma enyakatho. Amaphaneli abheke eningizimu, noma lawo adlula cishe ngama-degrees angu-15, angcono kakhulu.
Isiphetho
I-angle yokuthambekela ayibalulekile kangako kunalokho okucatshangwayo. Ukuphepha, ukusetshenziswa kwendawo, kanye nezici zemvelo kunomthelela omkhulu emalini engenayo. Ukuklama uhlelo lwe-PV olucabangela lezi zici kuzokhulisa imbuyiselo.
