El albedo Lulwalamano phakathi kwamandla abonakalisiweyo kunye nesiganeko kubude bokukhanya okubonakalayo kwaye kwenza ukuba iiplanethi zikhanye: bona, bengenamandla abo, babonisa inxenye yokukhanya abakufumanayo kwilanga. kuxhomekeke ekuthambekeni kwesiganeko sosasazo (ukusondela kokuthambekela kufikelela kwimbonakalo, kubaluleke ngakumbi ukubonakalisa) kunye nobume bomphezulu obonakalisayo. Ukwenza lula, ukubonakalisa komphezulu womhlaba kunxulumene nombala wawo: umzimba okhanyayo ubonakalisa ngokulula kunombala omnyama.
Umhlaba wekhephu une-albedo ephezulu kunedlelo. Ke, ikhephu linomndilili we-albedo we-0,7, ngelixa elehlathi eliluhlaza lingu-0,2. I-albedo yesijikelezi-langa imalunga ne-0,1, oko kuthetha ukuba malunga 30% yamandla angenayo elanga aqala kwakhona ngohlobo lwemitha ethe ngqo esithubeni. I-albedo yamazwekazi imalunga ne-34%, ngelixa iilwandlekazi zingama-26% kwaye amafu asezantsi aphakathi naphakathi aphakathi kwama-50% nama-70%.
Nangona kwinqanaba leeplanethi ibhalansi yamandla ilingana no-zero, kwiindawo ezimbalwa kumphezulu womhlaba apho sifumana khona ibhalansi kulingano. Ezinye iindawo zifumana amandla amaninzi kunokuba zikhupha; abanye, kwelinye icala, bakhupha ngaphezulu kunoko bakufumanayo. Ngokubanzi, iibhalansi zikwiintsalela ukuya kufana phakathi ko-35º no-40º. Kwezi ndawo zilinganayo, kwaye ngaphaya koko ziye zanqongophala. Umahluko kubungakanani bamandla afunyenweyo kunye nemeko yokukhupha ukufudumeza okanye ukupholisa umoya, izinto ezinegalelo kulwabiwo lwemozulu kunye nokujikeleza kwemozulu.
Kuya kufuneka ujonge ixabiso lemitha yelanga engaphandle. Isc = 1367 W / m ^ 2
