I-Solar Panel Commudithation Guide: Amaphaneli Okuqondanisa Nge-plug and Play Systems

Ukuqonda i-Plug ne-Play Systems

Amasistimu wokuxhuma nokudlala ashintsha ukufinyelela kumandla elanga ngokwenza ukufakwa kube lula. Ngokungafani nokufakwa kwe-photovoltaic kwendabuko okudinga ukungenelela kochwepheshe, lezi zixazululo zivumela abanikazi bezindlu ukuthi baxhume ngokuqondile amaphaneli abo elanga kugridi kagesi yasekhaya.

Izingxenye Ezibalulekile Zepulagi Nesistimu Yokudlala

Isistimu ephelele ihlanganisa izici eziningana ezixhumene:

• Amaphaneli elanga aguqulelwe ekucacisweni kwe-microinverter
• I-Microinverter iguqula i-current eqondile ibe yamanje eshintshanayo
• Intambo yokuxhuma enezixhumi ezimisiwe ze-MC4
• Uhlelo lokuqapha ukulandelela ukukhiqizwa kwamandla
• Amadivayisi okuphepha ahlanganisiwe (ukuvikelwa kokuhlinzwa)

Isihluthulelo sempumelelo silele ekusebenzisaneni okuphelele phakathi kwalezi zingxenye, ikakhulukazi phakathi kwamaphaneli elanga kanye ama-microinverters.

Imingcele Yezobuchwepheshe Eyisisekelo

I-Voltage yokusebenza

I-Voltage iyipharamitha ebaluleke kakhulu yokuqinisekisa ukuhambisana. Iphaneli ngayinye yelanga inezimbalwa ezibalulekile Amanani kagesi:

I-Maximum Power Voltage (Vmp) : Ngokuvamile phakathi kuka-30V kanye no-45V kumaphaneli okuhlala, leli nani kufanele lihambisane ne-microinverter's ibanga lokusebenza elilungile.

Vula i-Circuit Voltage (Voc) : Ihlala iphakeme kune-Vmp, akumele idlule i-voltage ephezulu yokufaka ye-microinverter, noma ingozi yokulimaza imishini.

I-Microinverter Operating Range : Ngokuvamile phakathi kuka-22V kanye no-60V kumamodeli okuhlala, leli windi linquma ukuhambisana nezinhlobonhlobo izinhlobo zamaphaneli.

Okwamanje namandla

Isekhethi Yamanje (Isc) : I-microinverter kufanele isekele umkhawulo wamanje ongalethwa iphaneli, okungenani ngomkhawulo wokuphepha ongu-10%.

Amandla Alinganiselwe : Amandla ephaneli kufanele ahambisane ngokufanelekile nama-85-110% wamandla alinganiselwe we-microinverter ukuze kuthuthukiswe ukusebenza kahle.

I-Temperature Coefficient

Ukwehluka kwezinga lokushisa kuthinta kakhulu ukusebenza. I-coefficient yezinga lokushisa lephaneli, evezwe ngo %/°C, ithonya i-voltage ephumayo futhi kufanele icatshangelwe ezibalweni zokuhambisana.

Imibandela Yokukhetha Yamaphaneli Ahambisanayo

Izinhlobo Zephaneli Ezinconyiwe

Ubuchwepheshe obuhlukahlukene bephaneli yelanga buveza izici ezihlukahlukene ezithinta ukuhambisana kwazo nepulaki kanye izinhlelo zokudlala. Uma uqhathanisa amaphaneli elanga e-monocrystalline vs polycrystalline , uhlobo ngalunye lunikeza izinzuzo ezihlukile.

Amaphaneli e-Monocrystalline : Inikeza ukusebenza kahle okuphakeme nokusebenza kwezinga lokushisa okuzinzile, ngokuvamile bakha okungcono kakhulu ukukhetha kwe-plug nezinhlelo zokudlala ngenxa ye-voltage yazo yokusebenza ebikezelwayo.

Amaphaneli e-Polycrystalline : Nakuba engasebenzi kahle, ahlala ehambisana nama-microinverter amaningi futhi amele umnotho onentshisekelo kukho inketho.

Izilinganiso Zamandla Ezilungile

Ukuze uthole ukuhambisana okuphezulu nama-microinverters ajwayelekile:

• 300-400W Amaphaneli : Ilungele ama-microinverter amaningi okuhlala
• 400-500W Amaphaneli : Idinga ama-microinverter anamandla
• >Amaphaneli angu-500W : Igcinelwe izinhlelo zokusebenza ezikhethekile ezinama-microinverter ashintshiwe

Ukumataniswa kwe-Panel-Microinverter

Izilinganiso Zokulinganisa

Isilinganiso esiphezulu sephaneli/i-microinverter ngokuvamile sihlala phakathi kuka-1:1 no-1.2:1. Ubukhulu bephaneli encane (kufika ku-20%) isiza ukunxephezela ukulahlekelwa futhi ithuthukise ukukhiqizwa phakathi nezimo zokukhanya okuphansi.

Izibonelo Zokucushwa Ezihambisanayo

Uhlobo loku-1 lokucushwa:

imibuzo ejwayelekile ukubuzwa

Ngingakwazi ukusebenzisa amaphaneli emikhiqizo ehlukene nge-microinverter efanayo?

Yize kungenzeka ngokobuchwepheshe uma imininingwane kagesi ihambisana, lo mkhuba awunconyiwe. Umehluko wokusebenza phakathi kwemikhiqizo ungadala ukungalingani futhi unciphise ukusebenza kahle okuphelele. Kungcono uku sebenzisa amaphaneli afanayo ukuze uqinisekise ukusebenza okuvumelanayo.

Kwenzekani uma ngeqa amandla amakhulu e-microinverter?

Ukweqiwa kwamandla kubangela ukusika: i-microinverter ikhawulela ukuphuma kwayo emandleni ayo alinganiselwe, ilahlekelwa amandla amaningi. Lesi simo, esamukelekayo ngezikhathi ezithile (iziqongo zokukhiqiza), siba yinkinga uma siphikelela, sibangela ukushisa ngokweqile nokunciphisa isikhathi sokuphila.

Ngikuqinisekisa kanjani ukuhambisana kwezingxenye esezithengiwe?

Bheka imininingwane yobuchwepheshe bemishini yakho bese uqinisekisa ukuthi amandla kagesi aphezulu ephaneli yakho (Vmp) ayehla ngaphakathi kwebanga le-MPPT le-microinverter yakho. Futhi qinisekisa ukuthi i-short circuit current (Isc) yephaneli ihlala ingaphansi kwe umkhawulo wamanje osekelwayo we-microinverter.

Ingabe izimo zezulu zithinta ukuhambisana?

Yebo, ngokuphawulekayo. Amazinga okushisa aphakeme aguqula izici zikagesi: amakhaza anyusa i-voltage ngenkathi ukushisa iyayinciphisa. Izibalo zokusebenzisana kufanele zihlanganise ubuncane besifunda sakho namazinga okushisa aphezulu ukuze uwagweme ukungasebenzi kahle.

Ingabe iphaneli yelanga ingalimaza i-microinverter engahambelani?

Nakanjani. I-voltage eyeqile (iphaneli enkulukazi) ingalimaza amasekhethi okokufaka ama-microinverter. Ngokuphambene, ngokweqile yamanje ingabangela ukushisa ngokweqile futhi icuphe ukuvikelwa, noma ilimaze unomphela okokusebenza. Ukuhambisana akunjalo ongakukhetha kodwa okubalulekile ekuphepheni.

Ingabe akhona ama-adaptha okwenza izingxenye ezingahambelani zihambelane?

Awekho ama-adaptha athembekile ukulungisa amandla kagesi ayisisekelo noma ukungahambisani kwamandla. Izixazululo ze-Workaround ngokuvamile kuphazamisa ukuphepha nokusebenza. Kuhlale kungcono ukutshala imali ezintweni ezihambisana ngokwemvelo esikhundleni sokufuna izixazululo zesikhashana.

Ukuze uthole ulwazi olwengeziwe mayelana nokufakwa kwe-solar nokufinyelela amathuluzi okuhlela ochwepheshe, vakashela ku PVGIS blog noma zama okwamahhala PVGIS 5.3 wokubala ukuze uqalise ngokuhlela iphrojekthi yakho yelanga.
