Procjena povratka investicija za predloženo rabljenje solarnih sustava u Poljskoj

This paper focuses on the assessment of possibilities to subsidize the purchase and installation of solar collectors in Poland by government or local government grants and special funds designed for this purpose. It analysis of costs and profits resulting from the application of solar installations in the process of heat generation for household requirements, by calculating the payback time, with taking into account prices of other energy carriers and the above mentioned subsidies. Collectors at present are manufactured solely from metals (copper, aluminium, Al-Mg alloys). The use of these materials is tied to considerable energy demand and the production technology is complex. This affects the economy of running a solar device.Članak je usmjeren na procjenu mogućnosti novčane potpore nabavke instalacija solarnih kolektora u Poljskoj od vlade ili lokalnih pokrovitelja te posebni fondovi utemeljeni u tu svrhu. Analizirani su troškovi i dobit kao rezultat primjene solarnih instalacija u procesima zagrijavanja po zahtjevima, proračuna povratka investicije, uzimajući u obzir cijene računa ostalih, tj. više drugih usporednih energija. Sadašnji kolektori ustrojeni su od metala (bakra, aluminija, Al-Mg legure). Rabljenje ovih materijala je u svezi energetskim zahtjevima i proizvodnom tehnologijom. Utjecaji ekonomije ovisni su o solarnim uređajima

Procjena i usporedba povratka ulaganja predloženog rabljenja solarnih sustava u Češkoj i Slovačkoj

The aim of the paper is to evaluate return of investment (ROI) and cost savings from proposed use of solar systems for residents funded by government grants. The paper deals with proposals for solar energy systems for various use, simple calculations of payback periods of solar systems financed with subsidy and without subsidy. Apart from climatic conditions, chemical composition the of the absorber and structural elements that are made of copper, respectively aluminum and Al-Mg alloy play an important role in assessing the payback period of the investment in solar panels.Cilj članka je procjena povratka ulaganja (PU) i ušteda troškova za predloženo rabljenje solarnih sustava stanovanja utemeljenih pod pokroviteljstvom vlade. Članak daje prijedloge za solarne energetske sisteme za različite upotrebe, jednostavni izračun termina povratka ulaganja sa i bez subvencioniranja. Dijelovi za klimatske uvjete, kemijski sastav absorbera i strukturalnih elemenata napravljeni od bakra, odnosno aluminija i Al-Mg legura igraju veliku ulogu u procjeni termina povratka investicije za solarne panele

Possibilities and problems of using pupillary reflex for subconscious detection of consumer preferences

The article describes the possibilities of using the pupillary light reflex for subconscious ascertainment of consumer preferences also in technical, industrial sectors. It describes the essence and use of pupillometry in marketing, types of pupillometry, practical suggestions as well as the prerequisites for future use in marketing. It suggests the procedures of an experiment with the use of an eye camera with an integrated pupillometer, and it points out to selected practical problems which must be eliminated during the experiments. If we wish to achieve growth of the industry the first necessary step is clear focus on the customer and on a user-friendly program of communication with customers and potential customers
