Iphaneli Yelanga Engu-120 Watt Izokhiqiza Amandla Angakanani?

 

1) Okushiwo Ngempela “ama-Watts angu-120”

Amaphaneli amaningi elanga alinganiswa ku-I-STC (Izimo Zokuhlola Ezijwayelekile): 1000 W/m² ukukhanya, izinga lokushisa lamaseli angu-25°C, kanye ne-spectrum efanele. Ensimini, izimo azivamile ukuba yi-STC.

Umthetho omuhle wephaneli egoqekayo yekhwalithi engu-120W:

• Amandla ajwayelekile esikhathi sangempela:~70–100Welangeni elinamandla (emini ecacile, i-engeli efanelekile)
• Iziqongo ezinhle kakhulu:ungabona kafushane110–120Wngokuqondanisa okuphelele kanye namazinga okushisa apholile
• Izimo ezimbi: 10–60Wesibhakabhakeni esinomswakama, umthunzi oyingxenye, noma i-engeli embi

Ukushisa kubaluleke kakhulu kunalokho abantu abaningi abakulindele. Njengoba amaseli elanga eshisa, i-voltage iyehla. Amaphaneli amaningi ane-coefficient yokushisa ezungeze-0.3% kuya ku-0.4% nge-°C(kuyahlukahluka ngohlobo lweseli). Ngosuku olushisayo, lokho kungasusa amandla abonakalayo phezulu ngisho nangaphansi kwelanga elikhanyayo.

2) Amandla Ansuku Zonke: Guqula ama-Watt abe ama-Watt-Hours

Lokho ongakugijima kuncike kukhoamandla ngosuku, kulinganiswa ngamahora e-watt (Wh). Isilinganiso esilula:

I-Wh yansuku zonke ≈ Ama-watt ephaneli × Amahora Elanga Eliphakeme × Ukusebenza kahle kwesistimu

Ukusebenza kahle kwesistimu okuvamile (isilawuli + ikhebula + ukulahlekelwa kokuguqulwa) kwe-solar ephathekayo kuvame ukuba70–85%.

Izibonelo zezimo zeModule Yelanga Egoqekayo engu-120W:

• Usuku oluhle lwasehlobo (amahora ama-5 okukhanya kwelanga okuphezulu):
  120W × 5h × 0.8 ≈480Wh/ngosuku
• Izimo ezimaphakathi (amahora angu-3.5 okuphuma kwelanga):
  120W × 3.5h × 0.8 ≈336Wh/ngosuku
• Isizini enamafu/ehlombe (amahora amabili okukhanya kwelanga okuphezulu):
  120W × 2h × 0.8 ≈192Wh/ngosuku

Ngakho-ke ohambweni oluningi lwangempela, lindela cishe200–500Wh ngosukukuye ngendawo nesimo sezulu.

3) Yini Engenza Lawo Magunya?

Nazi izibonelo ezingokoqobo ezisebenzisa~350Wh/ngosukunjengomphumela ophakathi nendawo:

• Ukushaja ifoni (10–15Wh ngokushaja okugcwele):~Izindleko ezingama-20–30
• Ithebhulethi (25–35Wh):~Izindleko ezingu-10–14
• I-Laptop (50–80Wh):~Izindleko ezingu-4–6
• Ifriji ye-compressor engu-12V (ejwayelekile engu-300–700Wh/ngosuku kuye ngokushisa kanye nomjikelezo womsebenzi):
  Iphaneli engu-120W ingambozaingxenyeukusetshenziswa kwansuku zonke, futhi ingasimboza ngokuphelele esimweni sezulu esipholile ngelanga elihle—ikakhulukazi uma ihambisana nesitoreji sebhethri esanele.

Kumadivayisi e-AC, khumbula ukuthi i-inverter yengeza ukulahlekelwa. Ukusebenzisa idivayisi engu-60W amahora ama-5 kuyinto300Wh, kodwa hlela eduze330–360Whngemuva kokungasebenzi kahle kwe-inverter.

4) Kungani Amamojula Agoqekayo Evame Ukusebenza Ngendlela Ehlukile Kunamaphaneli Aqinile

A Imodyuli Yelanga Egoqekayo engu-120WYakhelwe ukuphatheka kalula, hhayi ukuphelela kokufakwa ophahleni. Izici ezibalulekile ezihlobene nokusebenza okufanele uzibheke:

• Amaseli asebenza kahle kakhulu:amaphaneli amaningi aphathekayo e-premium asebenzisa amaseli amancane nxazonke20–23%ukusebenza kahle, okusiza endaweni elinganiselwe.
• Uhlobo lwesilawuli: I-MPPTngokuvamile ivuna amandla amaningi kune-PWM, ngokuvamileInzuzo engu-10–25%esimweni sezulu esipholile noma lapho i-voltage yephaneli iphakeme kakhulu kune-voltage yebhethri.
• Izitendi zokukhahlela/ukulungiswa kwe-engeli:Ukuhlosisa iphaneli kungathuthukisa kalula umphumela ngokuthi20–40%ngokumelene nokuyibeka phansi.
• Ukubekezelelana komthunzi:ngisho nomthunzi ongaphelele unganciphisa amandla kakhulu. Amaphaneli anokuhlelwa kwentambo okucatshangelwe kahle angaba nokuthethelela kakhudlwana, kodwa ukufiphaza kuhlala kuyinto ethandwayo.

5) Uhlu Lokuhlola Lomthengi Osheshayo

Ukwakha uhlelo lokuthenga oluthembekile:

• Khetha isikhombikubona sokuphuma esifanele:I-MC4kumajeneretha/abalawuli belanga; i-USB-C PD uma ushaja amadivayisi ngqo.
• Sebenzisa izintambo ezimfushane nezijiyile ukuze unciphise ukwehla kwamandla kagesi (ikakhulukazi kumaphaneli angu-12–20V).
• Hlanganisa nebhethri: ilanga liyashintshashintsha; indawo yokugcina izinto iyenza isebenziseke kalula.
• Beka phambili i-engeli kanye nendawo ebekwe kuyo: yigcine ingenamthunzi bese uyiqondisa kabusha izikhathi ezingu-2-3 ngosuku ukuze uthole isivuno esihle kakhulu.

Umugqa Ophansi

Iphaneli yelanga engu-120W ingakhiqizakufika ku-120Wezimweni ezinhle kakhulu, kodwa abasebenzisi abaningi kufanele balindele70–100Wngesikhathi selanga elinamandla futhi cishe200–500Wh ngosukukuye ngamahora okushisa kwelanga aphezulu kanye nokulahlekelwa yisistimu. Uma ungitshela indawo/isizini yakho, ukuthi ufuna ukusebenzisa ini (ifriji, i-laptop, imodeli yesiteshi sikagesi), nokuthi uzosebenzisa i-MPPT yini, ngingalinganisa amandla akho ansuku zonke ngokunembe kakhudlwana futhi ngincome ukuthi ngabe i-120W yanele noma kufanele uyikhulise.
