Sun as a Renewable Source of Energy

U ovom radu analizira se solarna energija kao obnovljiva vrsta energije i kao takva je potencijalna zamjena fosilnim gorivima. Uvodno se opisuje Sunce, kako nastaje solarna energija, koje su njene mane i prednosti, svestranost primjene solarne energije, efikasnosti različitih solarnih komponenata i sustava, teorijska procjena efikasnosti jednog sustava, ekonomski aspekt solarne energije i u konačnici pogled na budućnost i inovacije ovakvih sustava. Srž ovog rada je proračun efikasnosti solarnog sustava prema autoru Randy Geeu koji je teorijski objašnjen korak po korak i zatim primijenjen na realnom solarnom sustavuza proizvodnju vodene pare u tvornici hrane.This paper analyzes solar energy as a renewable type of energy and as such is a potential alternative to fossil fuels.It is described in the introduction what Sun is, how solar energy is generated, what its pros and cons are, the versatility of solar energy utilization, the efficiency of various solar components and systems, theoretical evaluation of a system`s efficiency, the economic aspect of solar energy and finally a glance at the future and inovation of such systems. The core of this paper is the calculation done by the author Randy Gee that is theoretically explained step by step and then applied to an example of one solar system in the function of supplying steam to the food production factory
