Ekonomska efikasnost solarnih kolektora i PV panela

Abstract

U radu se razmatra ekonomska efikasnost solarnih kolektora i PV panela (u daljem tekstu: solarni konvertori), putem cost-benefit analize i elemenata analize opravdanosti. U analizu su uključene varijante ispitivanja ekonomske efikasnosti solarnih konvertora standardnog tipa i varijanta sa uređajem koji se pokreće u toku celoga dana prateći Sunce, tj. postavljajući aktivnu površinu upravno na njegove zrake, što omogućava 250% veću energetsku efikasnost. Na primeru 1m2 solarnog konvertora (sa ugradnjom novog uređaja) u odnosu na standardne sisteme (bez uređaja) procenjeno je da je njihovo korišćenje sa ugradnjom novog uređaja ekonomski isplativije zbog ukupnih efekata ulaganja (uštede energije iz sistema), kraćeg perioda povraćaja ulaganja (5,1 godina u odnosu na 6,9 godina), nižeg obima investicionih ulaganja, ušteda u troškovima održavanja i sl.

The paper analysed the economical efficiency of solar collectors and PV systems (solar convertor) by cost-benefit analysis and by elements of feasibility analysis. In this analysis are included different options of research of economical efficiency standard type of solar convertor, and option with included the convertor which moves following the sun all day along, meaning that its active surface always positions itself to get the sun rays falling on it vertically, which supports 250% more energy efficiency. For example, 1m2 of the solar convertor (with the new mechanism included), compared to the standard systems without this new mechanism has been estimated as more efficient because the total effects of investment are bigger (saving energy from the system), because of a short period of return investment (5,1 year in relation to 6,9 year), a slow level of investment, saving in maintenance costs, etc.
