“…Previously RETScreen has been used to assess the feasibility of wind farm development in Algeria [214], the feasibility of solar water heating in Lebanon [215], the viability of solar PV in Egypt [216], as well as identifying the potential of a building-integrated PV system [217] and GHG reductions in the residential sector [218]. A detailed assessment of the projects and results completed using RETScreen is available in [219].…”

“…Comparatively many works concern the characteristics of temporal and spatial distribution of solar conditions, analyzed most often according to months (Aksoy, 1999;Power, 2003;Darula and Kittler, 2004;Cancillo et al, 2005;Dolinar, 2006;Sanchez-Lorenzo et al, 2008;El-Shimy, 2009;Fadare, 2009), less frequently according to seasons and much less according to plant development stages (Power, 2003;Matzarakis and Katsoulis, 2006). Therefore, it is difficult to compare the obtained results of the current work with other results.…”

Solar energy, accessible to plants during sunshine from the sunrise to the sunset is of key importance in productivity of agrocenoses. The aim of the work was to determine risk of pickling cucumber cultivation caused by an unfavorable course of sunshine duration in Poland on the basis of a 40-year research period . The research into the subject was undertaken due to frequent occurrence of sunshine deficiency in Poland and its high temporal and spatial variability. Effect of solar conditions described by sunshine duration in the five development stages on the quantity of the total and marketable yield of cucumber with consideration of a linear trend of an independent variable was determined by means of multiple regression analysis. The accuracy of the equations was evaluated on the basis of, among other things, determination coefficient, average relative forecast error and the indexes: mean bias error (MBE), mean absolute bias error (MABE) and root mean square error (RMSE). Cucumber (Cucumis sativus L.) yield was confirmed for the period from the end of emergence to the beginning of flowering and from the beginning of harvesting to the end of harvesting. Cucumber yield was lower by 18% than the multiannual average in the years 1966-2005 every 1.5-2 years -in the case of the occurrence of the shortage in the period from the end of emergence to the beginning of flowering and by 12-15% every 2-3 years in the period from the beginning of harvesting to the end of harvesting. In four years, out of the 40 considered ones, simultaneously in both cucumber development stages, unfavorable solar conditions occurred, causing reduction by at least 5% in the total yield of the plant in Poland, and in three years -the marketable yield. Key words: development, growth, reduction in yield, solar conditions Risco do cultivo de campo de pepino decapado causado por condições desfavoráveis de duração de brilho solar RESUMO: A disponibilidade de energia solar para as plantas desde o nascer ao por do sol é de fundamental importância para todo agronegócio. O objetivo deste trabalho foi determinar o risco da produção de pepino (Cucumis sativus L.) decapado causado pelo curso desfavorável de duração da radiação solar na Polônia, baseado em um período de 40 anos de pesquisa . A pesquisa foi realizada pelo fato da ocorrência frequente de deficiência de insolação na Polônia e sua alta variabilidade temporal e espacial. O efeito das condições solares descritas pela duração da insolação foi estudado em relação às produtividades total e comerciável de pepino, considerando uma tendência linear de uma variável independente. A precisão das equações foi avaliada com base no coeficiente de determinação, erro médio relativo de precisão e índices: erro médio de bias, erro médio absoluto de bias e raiz do erro médio quadrado. A produtividade foi analisada a partir da emergência até o início do florescimento e do inicio ao fim da colheita. A produtividade de pepino foi 18% menor em relação a media multianual dos anos 1966-2005 cada 1,5-2 anos -n...

“…Photovoltaic potential is often assessed by technological or economical evaluation (Fath et al, 2015;Lang, Ammann, & Girod, 2016;Mondal & Islam, 2011;El-Shimy, 2009;Seng, Lalchand, & Lin, 2008). The potential has been evaluated by photovoltaic energy generation based on total annual solar radiation (Hofierka & Kaňuk, 2009;Lukač et al, 2014), surfaces for calculation predictions have mostly been limited only to roof implementation, and results generally displayed as numbers or diagrams (Matrawy, Mahrous, & Youssef, 2015).…”

Abstract:Photovoltaic (PV) installation potential on residential building envelope in equatorial region was analysed by 3D insolation colour rendering employing BIM Revit solar analysis tool. Monthly global solar radiation calculation was employed to investigate solar potential in study case area. Actual energy consumption of residential sector was used as a base to predict energy demand for next 10 years. Predicted energy demand was then used to calculate the area needed for photovoltaic installation to balance future energy demand. The energy consumption by residential building was divided into five different installed electrical power capacities namely 450 Watt, 900 Watt, 1300 Watt, 2200 Watt and 3500-6600 Watt. Study results suggest that the potential location of photovoltaic panel installation on detached houses is on the roof, East, and West walls. Abundant solar energy in equatorial region was proved by high potential of PV energy generation 7 -9 kW/m² for amorphous silicon, 17 -18 kW/m² for polycrystalline silicon, and 19 -23 kW/m² for monocrystalline silicon. The roof element alone can provide sufficient electrical energy generated by installed photovoltaic panels for the next 10 years. The area needed to supply 450W -6600W installed power capacity were 13 -75 m² for monocrystalline silicon, 23 -120 m² for polycrystalline silicon, and 50 -259 m² for amorphous silicon. To conclude, implementation of photovoltaic installations on residential buildings have a huge potential to secure not only recent energy consumption, but also future energy demand.
