Ukukhanya kwengadi ye-solar kuyidivayisi yokukhanyisa yangaphandle esebenzisa amandla elanga ukuze ishaje futhi inikeze ukukhanya ebusuku. Lolu hlobo lwesibani ngokuvamile luqukethe amaphaneli elanga, amalambu e-LED noma amalambu okukhanyisa amandla, amabhethri namasekhethi okulawula. Emini, ama-solar panel amunca ukukhanya kwelanga futhi agcine amandla kumabhethri, futhi ebusuku ahlinzeka ngokukhanya ngokulawula umjikelezo ukuze kukhanye izibani ze-LED noma ama-bulb onga amandla.

Njengamanje, izibani zensimu yelanga zithuthuka kahle emakethe. Njengoba abantu benaka kakhulu amandla aluhlaza ahambisana nemvelo, izibani zengadi zelanga zithandwa kancane kancane ngabathengi njengendlela yokukhanyisa ugesi kanye nemvelo enobungani. Izibani zengadi yelanga zezitayela nemisebenzi ehlukahlukene nazo ziyavela emakethe, zihlangabezana nezidingo ezahlukahlukene zabathengi zokukhanyisa ngaphandle.

Abathengi bathanda kakhulu izibani zengadi zelanga. Banombono omuhle ngale mishini yokukhanyisa yangaphandle eyonga ugesi, engasizungezile, elula futhi esebenzayo. Izibani zensimu yelanga azinikezi nje ukukhanya okwanele kwezikhala zangaphandle, kodwa futhi zonga izindleko zamandla, ngakho-ke zamukelwa kabanzi.

Ngokuvamile, izibani zensimu yelanga okwamanje zisesigabeni sokuthuthukiswa okunamandla, futhi abathengi banokukhetha okuphezulu kubo. Ngokuthuthuka okuqhubekayo kobuchwepheshe kanye nokusungulwa komkhiqizo okuqhubekayo, izibani zengadi yelanga kulindeleke ukuthi ziqhubeke nokuduma emakethe esikhathini esizayo.
