We can use solar energy in two different ways: electric and thermal. As long as the Sun flares up in the upper atmosphere of the Earth, the temperature increases. The amount of solar energy that a person can potentially use differs from the amount of energy that is near the earth’s surface.
The potential solar energy that could be used by humans differs from the amount of solar energy present near the surface of the planet because factors such as geography, time variation, cloud cover, and the land available to humans limit the amount of solar energy that we can acquire.
Geography affects solar energy potential because areas that are closer to the equator have a greater amount of solar radiation. However, the use of photovoltaics that can follow the position of the sun can significantly increase the solar energy potential in areas that are farther from the equator.Time variation effects the potential of solar energy because during the nighttime there is little solar radiation on the surface of the Earth for solar panels to absorb. This limits the amount of energy that solar panels can absorb in one day. Cloud cover can affect the potential of solar panels because clouds block incoming light from the sun and reduce the light available for solar cells.
Tunaweza kutumia nishati ya jua kwa njia mbili tofauti: umeme na joto. Muda mrefu kama Jua linawaka katika angahewa la juu la Dunia, joto huongezeka. Kiasi cha nishati ya jua ambayo mtu anaweza kutumia kinatofautiana na kiasi cha nishati kilicho karibu na uso wa dunia. Nishati ya jua ambayo inaweza kutumika na wanadamu inatofautiana na kiasi cha nishati ya jua iliyopo karibu na uso wa sayari kwa sababu sababu ya mambo kama vile jiografia, mabadiliko ya wakati, kifuniko cha mawingu, na ardhi inayopatikana kwa wanadamu hupunguza kiasi cha nishati ya jua ambayo tunaweza kupata. Jiografia huathiri uwezo wa nishati ya jua kwa sababu maeneo yaliyo karibu na ikweta yana kiasi kikubwa cha mnururisho wa jua. Hata hivyo, matumizi ya photovoltaics ambayo inaweza kufuata nafasi ya jua inaweza kwa kiasi kikubwa kuongeza uwezo wa nishati ya jua katika maeneo ambayo ni mbali zaidi kutoka ikweta. mabadiliko ya muda athari ya uwezo wa nishati ya jua kwa sababu wakati wa usiku kuna kidogo mwangaza wa jua juu ya uso wa dunia kwa paneli za jua kunyonya. Hilo hupunguza kiasi cha nishati ambacho paneli za jua zinaweza kunyonya kwa siku moja. Wingu linaweza kuathiri uwezo wa paneli za jua kwa sababu mawingu huzuia mwanga unaokuja kutoka kwa jua na kupunguza mwanga unaopatikana kwa seli za jua.
