El albedo Ngubudlelwano phakathi kwamandla akhonjisiwe nesigameko ebangeni lokukhanya okubonakalayo futhi kwenza amaplanethi akhanye: la, angenawo amandla ngokwawo, akhombisa ingxenye yokukhanya abakuthola kuLanga. kuncike ekuthambekeni kwemisebe yesehlakalo (lapho ukuthambekela kusondela kokuqondakalayo, kubaluleke kakhulu ukubonakalisa) nesimo sobuso obukhanyayo. Ukuze kube lula, amandla akhombisa indawo ahlobene nombala wawo: umzimba okhanyayo ubonakalisa kalula ukwedlula omnyama.
Inhlabathi embozwe yiqhwa ine-albedo ephakeme kunedlelo. Ngakho-ke, iqhwa line-albedo elinganiselwa ku-0,7, kanti lelo lehlathi eliluhlaza lingu-0,2. I-albedo eyiplanethi icishe ibe ngu-0,1, okusho ukuthi cishe i-a 30% amandla angenayo elanga aqala futhi ngendlela yemisebe eqondile ebheke esikhaleni. I-albedo yamazwekazi icishe ibe ngama-34%, kanti leyo yolwandle ingama-26% kanti leyo yamafu asezingeni eliphansi naphakathi aphakathi kuka-50% no-70%.
Yize ngokwesilinganiso samaplanethi i- ukulinganisela kwamandla ilingana no-zero, ezindaweni ezimbalwa ebusweni bomhlaba lapho sithola khona ibhalansi ngokulingana. Ezinye izindawo zithola amandla amaningi kunokukhipha; abanye, ngakolunye uhlangothi, bakhipha okungaphezu kwalokho abakutholayo. Ngokuvamile, amabhalansi asele ngaphezu kokufana phakathi kuka-35º no-40º. Kulezi zindawo bayalingana, futhi ngale kwalokho baba nokuntula. Ukwehluka kwenani lamandla atholakele futhi akhipha isimo ukufudumeza noma ukupholisa komoya, izinto ezinomthelela ekusatshalalisweni kwesimo sezulu nokusakazwa komkhathi.
Kufanele uhlole inani lemisebe yelanga engaphandle. Isc = 1367 W / m ^ 2
