Expected cost benefits of building-integrated PVs in UK, through a quantitative economic analysis of PVs in connection with buildings, focused on UK and Greece

Socioeconomic evaluation of green energy investments

“…Initially, research on the economic development of photovoltaics in the UK and Greece indicates that photovoltaics did not make a profit in 2003 (Spanos and Duckers, 2004). On the contrary, for 2009 and on, photovoltaics are an attractive investment in both the countries.…”

“…A main reason for this is that technological innovations led the levelized cost of energy of photovoltaics to significantly fall during the last years (Wang et al, 2011;Mundada et al, 2016;Parrado et al, 2016). Spanos and Duckers (2004) also noted that while the climate in Greece is more encouraging for the installation of photovoltaics, in the UK the economic climate is more favorable. The biggest obstacle to installing photovoltaics in buildings is their high cost, which, due to falling prices, is expected to be overcome.…”

“…Photovoltaics' main advantages as determined in various studies are the high degree of social acceptance (Heras-Saizarbitoria et al, 2011;Phuangpornpitak and Kumar, 2011;Kaldellis et al, 2012;Tsantopoulos et al, 2014), the low maintenance cost (Singh, 2013), the ease of installation into residential roofs and buildings instead of glass and the high urban use (Tyagi et al, 2013;Moosavian et al, 2013;Radhi, 2012;Spanos and Duckers, 2004;Loulas et al, 2012) and the high yields in sunny areas (Tsantopoulos et al, 2014;Fantidis…”

On the use of hourly pricing in techno-economic analyses for solar photovoltaic systems

“…For building owners considering a renewable energy installation, investment analysis requires predicting future electricity prices. A common method for pricing is to assume the most recent retail electricity price and apply it to all hours of the year [4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21]. This is usually a reasonable assumption given that in many places where grid connected PV is installed, owners are given a fixed feed-in tariff (FiT), power purchase agreement (PPA) or have net metering based on a static retail price [22].…”

Κοινωνικοοικονομική Αξιολόγηση Πράσινων Επενδύσεων Και Πράσινων Προϊόντων

“…Σχετικά με τα φωτοβολταϊκά, τα κυριότερα πλεονεκτήματα είναι τα ακόλουθα: α) υψηλός βαθμός κοινωνικής αποδοχής (Kaldellis et al, 2012;Heras-Saizarbitoria et al, 2011;Phuangpornpitak andKumar, 2011 Tsantopoulos et al, 2014), β) χαμηλό κόστος συντήρησης (Singh;, γ) ευκολία ενσωμάτωσης στις οροφές κατοικιών αλλά και στα κτίρια, αντί γυαλιού, δ) υψηλή αστική χρήση (Tyagi et al, 2013;Moosavian et al, 2013;Radhi, 2012;Spanos and Duckers, 2004;Loulas et al, 2012), ε) υψηλή απόδοση σε περιοχές με ηλιοφάνεια (Tsantopoulos et al, 2014;Fantidis et al, 2013). Από την άλλη πλευρά, κύρια μειονεκτήματα αποτελούν: α) η δυσκολία αποθήκευσης της ενέργειας (Bruch and Mülle, 2014), β) η ανάγκη για επιδότηση σύμφωνα με τη διαθεσιμότητα ηλιακής ακτινοβολίας (Singh, 2013), γ) η περιβαλλοντική επιβάρυνση κατά το στάδιο κατασκευής τους και η ανάγκη διαχείρισης στο τέλος του κύκλου ζωής (Aberle et al, 2013;Tyagi et al, 2013), δ) το κόστος εγκατάστασης θεωρείται ακόμα υψηλό και ο χρόνος αποπληρωμής μεγάλος (Faiers and Neame, 2005;Swift, 2013;Pillai and McLaughlin, 2013;Stefanovic et al, 2014;Orioli and Di Gangi, 2014).…”
