Emashumini ambalwa eminyaka adlule, amandla elanga avele njengendlela enenzuzo futhi eqhubekayo emithonjeni yamandla evamile. Njengoba ubuchwepheshe belanga buqhubeka nokuvela, kanjalo nezingxenye ezihlukahlukene zamaphaneli elanga. Enye yezingxenye ezibalulekile yibhokisi le-solar junction. Kulesi sihloko, sihlola ukuvela kwamabhokisi e-solar junction, izinto ezintsha eziwabumbayo, kanye namathrendi athembisayo esikhathi esizayo embonini yelanga.
Iibhokisi le-solar junctioniyisixhumanisi esibalulekile phakathi kwephaneli yelanga kanye nesistimu kagesi. Lawa mabhokisi agcina izintambo zikagesi nezilawuli ukuze kuqinisekiswe ukusebenza kahle kwamaphaneli elanga. Ezinsukwini zakuqala zobuchwepheshe belanga, amabhokisi okuhlangana ayeyizindawo ezivalekile ezinikeza ukuvikeleka okuyisisekelo nokuxhumana. Nokho, njengoba isidingo samandla elanga sikhula, isidingo samabhokisi okuhlangana athuthukile sabonakala.
Izinqubo ezintsha zokuqala ezinkulu emabhokisini okuhlangana kwelanga ziye zathuthukiswa ukusebenza kahle nokuqina. Abakhiqizi sebeqala ukusebenzisa izinto ezingcono nezindlela zokuvala ukuze bathuthukise impilo nokusebenza kwamabhokisi okuhlangana. Lokhu kuvumela amaphaneli elanga ukuthi amelane nezimo zezulu ezinzima futhi asebenze kahle isikhathi eside.
Enye intuthuko ebalulekile emabhokisini okuhlangana kwelanga ukuhlanganiswa kobuchwepheshe bokulandelela amaphuzu aphezulu (MPPT). I-MPPT iqinisekisa ukuthi amaphaneli elanga asebenza ngamandla amakhulu ezimweni zezulu ezishintshashintshayo. Ngokuqhubeka nokuqapha amazinga kagesi kanye namazinga amanje, ubuchwepheshe be-MPPT benza amaphaneli elanga akhiphe amandla amaningi elangeni. Lokhu okusha kukhulisa kakhulu ukusebenza kahle okuphelele kwamaphaneli elanga futhi kuwenza angabizi kakhulu.
Njengoba ubuchwepheshe buthuthuka, abacwaningi sebeqala ukuhlola amandla amabhokisi e-smart junction. Amabhokisi afakwe izici zokuqapha ezithuthukisiwe zokuxhumana eziwavumela ukuthi anikeze idatha yesikhathi sangempela ekusebenzeni kwamaphaneli elanga angawodwana. Amabhokisi e-Smart junction anika amandla ukuxazulula inkinga okukude futhi aqinisekise ukunakekelwa okufika ngesikhathi, athuthukise ukusebenza kahle nokuthembeka kwezinhlelo zamandla elanga.
Ikusasa lamabhokisi ahlanganayo elanga libukeka lithembisa, ngamathrendi ambalwa aqanjwayo emkhathizwe. Omunye umkhuba onjalo ukuhlanganiswa kwama-microinverters ngaphakathi kwebhokisi lokuhlangana. Ama-Microinverters aguqula i-direct current (DC) ekhiqizwe amaphaneli elanga abe i-alternating current (AC) ukuze isetshenziswe ngokushesha noma ifakwe kugridi. Ngokuhlanganisa ama-microinverter namabhokisi okuhlangana, ukufakwa kwamaphaneli elanga kuba yimodular futhi kusebenza kahle njengoba iphaneli ngayinye ingasebenza ngokuzimela, ithuthukise ukukhiqizwa kwamandla.
Ukwengeza, intuthuko kwezokuxhumana okungenantambo kanye nobuchwepheshe be-inthanethi Yezinto (IoT) ingase ilolonge ikusasa lamabhokisi okuhlanganisa ilanga. Amabhokisi e-Smart junction azokwazi ukuxhumana nezinye izingxenye zesistimu sonozungezilanga, njengama-inverter namabhethri. Lokhu kuxhumana okungenazihibe kuzokwenza ukuthi kube nokuphathwa okungcono, ukuqapha kanye nokulawula izinhlelo zokuphehla amandla elanga, ekugcineni kukhuliswe ukuphuma kwamandla.
Imboni kanozungezilanga iyaqhubeka nokwenza intuthuko emangazayo, futhi amabhokisi e-solar junction abambe iqhaza elikhulu kule ntuthuko. Ukusuka endaweni ebiyelwe kuya ebhokisini le-junction elithuthukisiwe, kube uguquko. Ngokuqhubeka nokuqamba okusha okugxile ekuthuthukiseni ukusebenza kahle, ukuhlanganisa ama-microinverters, kanye nokukhulisa amakhono e-IoT,ibhokisi le-solar junctionuthembisa ukuguqula indlela esisebenzisa ngayo amandla elanga. Njengoba izwe liya ngokuya liqaphela isidingo samandla avuselelekayo, ikusasa lamabhokisi okuhlangana elanga liyakhanya ngokuqinisekile.
