Iza kuvelisa amandla angakanani iphaneli yelanga eyi-120 Watts?

 

1) Oko Kuthethwa Yi-"120 Watts" Ngokwenene

Uninzi lweephaneli zelanga zilinganiswa kwiI-STC (Iimeko zoVavanyo eziQhelekileyo): 1000 W/m² irradiance, ubushushu beeseli ezingama-25°C, kunye ne-spectrum efanelekileyo. Entsimini, iimeko azifane zibe yi-STC.

Umgaqo olungileyo wephaneli egoqekayo ye-120W esemgangathweni:

• Amandla aqhelekileyo exesha langempela:~70–100Welangeni elinamandla (emini ecacileyo, i-engile efanelekileyo)
• Iincopho ezilungileyo kakhulu:ungabona kancinci110–120Wngokulungelelaniswa okugqibeleleyo kunye namaqondo obushushu apholileyo
• Iimeko ezimbi: 10–60Wkwisibhakabhaka esimnyama, umthunzi ongaphelelanga, okanye i-engile embi

Ubushushu bubaluleke ngaphezu kokuba abantu abaninzi belindele. Njengoko iiseli zelanga zishushu, i-voltage iyehla. Iiphaneli ezininzi zine-coefficient yobushushu ejikeleze-0.3% ukuya ku -0.4% nge °C nganye(iyahluka ngokweentlobo zeeseli). Ngemini eshushu, oko kunokususa amandla abonakalayo phezulu nokuba lilanga elikhanyayo.

2) Amandla Emihla ngemihla: Guqula iiWatts zibe ziiWatt-Hours

Oko unokubaleka kuxhomekekeamandla ngosuku, ilinganiswa ngee-watt-hours (Wh). Uqikelelo olulula:

I-Wh yemihla ngemihla ≈ Iiwati zephaneli × IiYure zeLanga eziPhezulu × Ukusebenza kakuhle kwenkqubo

Ukusebenza kakuhle kwenkqubo eqhelekileyo (isilawuli + intambo + ilahleko yokuguqulwa) kwilanga eliphathwayo kudla ngokuba70–85%.

Imizekelo yeemeko zeModyuli yeSolar egoqekayo ye-120W:

• Usuku oluhle lwasehlotyeni (iiyure ezi-5 zelanga elicothayo):
  120W × 5h × 0.8 ≈480Wh/ngosuku
• Iimeko eziqhelekileyo (iiyure ezi-3.5 zelanga eliphuma kakhulu):
  120W × 3.5h × 0.8 ≈336Wh/ngosuku
• Ixesha elinamafu/amagxa (iiyure ezimbini zelanga eliphakamileyo):
  120W × 2h × 0.8 ≈192Wh/ngosuku

Ngoko ke kwiihambo ezininzi zokwenyani, lindela kancinci200–500Wh ngosukukuxhomekeke kwindawo kunye nemozulu.

3) Yintoni Enokwenza Loo Mandla?

Nazi imizekelo yokwenyani esebenzisa~350Wh/ngosukunjengesiphumo esiphakathi:

• Ukutshaja ifowuni (10–15Wh ngetshaja epheleleyo):~Iintlawulo ezingama-20–30
• Ithebhulethi (25–35Wh):~Iintlawulo ezili-10–14
• Ilaptop (50–80Wh):~Iintlawulo ezi-4–6
• Ifriji yecompressor ye-12V (eqhelekileyo yi-300–700Wh/ngosuku kuxhomekeke kubushushu kunye nomjikelo womsebenzi):
  Iphaneli ye-120W inokugubungelainxalenyeukusetyenziswa kwemihla ngemihla, kwaye ingayigubungela ngokupheleleyo kwimozulu epholileyo enelanga elihle—ingakumbi xa idibene nendawo yokugcina ibhetri eyaneleyo.

Kwizixhobo ze-AC, khumbula ukuba i-inverter yongeza ilahleko. Ukusebenzisa isixhobo se-60W iiyure ezi-5 kuyasebenza.300Wh, kodwa cwangcisa kufutshane330–360Whemva kokungasebenzi kakuhle kwe-inverter.

4) Kutheni iiModyuli eziSongwayo zihlala zisebenza ngendlela eyahlukileyo kuneePaneli eziqinileyo

A Imodyuli yelanga egoqekayo eyi-120WYakhelwe ukuba ithwaleke lula, hayi ukuba igqibelele xa ifakelwa eluphahleni. Iimpawu ezibalulekileyo ezinxulumene nokusebenza ekufuneka uzijonge:

• Iiseli ezisebenzayo kakhulu:iiphaneli ezininzi eziphathwayo zeprimiyamu zisebenzisa ii-mono cells ezijikeleze20–23%ukusebenza kakuhle, okunceda kwindawo encinci yomphezulu.
• Uhlobo lomlawuli: I-MPPTidla ngokuqokelela amandla amaninzi kunePWM, rhoqoIinzuzo ze-10–25%xa kupholile okanye xa i-voltage yepaneli iphezulu kakhulu kune-voltage yebhetri.
• Izitendi zokukhaba / uhlengahlengiso lwe-engile:Ukujolisa iphaneli kunokuphucula imveliso ngokulula20–40%ngokuchasene nokuyibeka tyaba.
• Ukunyamezelana komthunzi:nokuba umthunzi ongaphelelanga unokunciphisa amandla kakhulu. Iiphaneli ezinesakhiwo sentambo esicingisisiweyo zinokuba luncedo ngakumbi, kodwa umthunzi uhlala uyinto ebalulekileyo.

5) Uluhlu lokujonga umthengi okhawulezayo

Ukwakha isicwangciso sokuthenga esithembekileyo:

• Khetha ujongano oluchanekileyo lwemveliso:MC4kwiijenereyitha/abalawuli belanga; i-USB-C PD ukuba utshaja izixhobo ngokuthe ngqo.
• Sebenzisa iintambo ezimfutshane nezityebileyo ukunciphisa ukwehla kombane (ingakumbi kwiiphaneli ze-12–20V).
• Dibanisa nebhetri: ilanga lihlala lihleli; indawo yokugcina izinto iyenza isebenziseke.
• Beka phambili i-engile kunye nendawo ekubekwe kuyo: yigcine ingenamthunzi kwaye uyijongise kwakhona izihlandlo ezi-2-3 ngemini ukuze ufumane isivuno esihle.

Okukwintsusa

Iphaneli yelanga ye-120W inokuvelisaukuya kuthi ga kwi-120Wkwiimeko ezifanelekileyo, kodwa uninzi lwabasebenzisi kufuneka balindele70–100Wngexesha lelanga elinamandla kwaye malunga200–500Wh ngosukukuxhomekeke kwiiyure zokukhanya kwelanga okuphezulu kunye nokulahleka kwenkqubo. Ukuba undixelela indawo/ixesha lakho, into ofuna ukuyisebenzisa (ifriji, ilaptop, imodeli yesikhululo samandla), kunye nokuba uza kusebenzisa iMPPT, ndingaqikelela amandla akho emihla ngemihla ngokuchanekileyo kwaye ndicebise ukuba i-120W yanele na okanye ukuba kufuneka uyinyuse ubungakanani.
