“…Some reasons have led to this phenomena such as: it did not create noise, releases no pollution (Lukač et al, 2014;Mondal & Islam, 2011), and is easy to integrate with existing building (Vieira, Moura, & de Almeida, 2017). In generating energy, several factors influence photovoltaic productivity namely: photovoltaic panel (tilt angle, type and area) and climatic elements (irradiation, ambient temperature, and wind speed) (Othman & Rushdi, 2014;Lang, Ammann, & Girod, 2016).…”

“…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).…”

“…Instead of annual solar radiation data, this study used monthly global horizontal irradiation data to calculate photovoltaic energy generation, thus it can be compared with monthly energy demand. In photovoltaic potential studies, certain methods and tools have been utilized including calculation software such as HOMIE (Lang, Ammann, & Girod, 2016), Open-source solar radiation tools and 3D city models implemented in GIS (Hofierka & Kaňuk, 2009), and HOMER (Mondal & Islam, 2011;Adaramola, 2014). These software calculate for a large-scale area thus resulting in a large deviation on calculations when implemented on an individual building.…”

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.

“…Regulatory mechanisms as feed in tariffs and net-metering laws as well as the local cost structure (installation, capital and electricity costs) are quantitative factors that are usually used for the economic PV potential evaluation [39]. An attractive economic potential based on these factors is necessary, but does not guarantee the market success of PV [40].…”

Technical, Economical and Social Assessment of Photovoltaics in the Frame of the Net-Metering Law for the Province of Salta, Argentina

Central and Northern Argentinean regions possess a high potential for the generation of solar energy. The realization of this potential is an alternative to alleviate the strong dependence on imports of fossil energy and to reduce the CO 2 emissions of the country. However, the adoption of photovoltaics (PV) is still in an incipient state. It is undermined by a context of heavily subsidized electricity prices, high equipment and installation costs and a lack of information, training and experience in handling PV technology. This paper presents a techno-economical assessment of the application of the recently enacted net-metering law for promoting renewable energies (RE) in the Province of Salta (Northwest Argentina) for the case of PV. The assessment shows under which conditions and for which types of consumers it is profitable to adopt PV in the context of the law. This analysis is supported by a participatory planning approach as a study of stakeholders' attitudes towards RE, intentions to adopt PV and their knowledge about the law. The results of this study and the economical analysis serve to provide recommendations aimed at increasing the level of PV adoption in the province.

The social profitability of photovoltaics in Germany

While Germany has led the market in photovoltaic (PV) implementation throughout the last decade, there has been increasing criticism of PV support policies due to their high cost. Although declining, the levelized cost of electricity (LCOE) from PV is still above the German wholesale electricity price. However, using LCOE as an evaluation yardstick falls short in at least 2 respects: It neither takes into account integration costs rising with PV penetration (ie, undervaluing its actual cost) nor avoided externalities of replacing conventional for renewable generation (social cost overvaluation). We thus calculate the social profitability of PV in Germany by including not only private costs and benefits but also integration costs to the electricity system and avoided environmental externalities, using the internal rate of return and the profitability index as indicators. Our results show that when these factors are considered, the social profitability of PV in Germany is higher than 10% at the lower bound of the social cost of carbon (150€/tCO2) up to a penetration level of at least 15% and positive up to a penetration level of at least 25%. Results also show the level of private profitability if all externalities were internalized and assert that subsidies are justified to align private and social profitability. The proposed method could be used as a complementary indicator to private profitability by public institutions, development banks, and companies with social responsibility values.
