Analysis of photovoltaic potential in urban areas: the effect of the eurozone financial crisis
2012
The aim of this paper is to estimate how the profitability of grid-connected PV systems may vary month by month due to the changes in all parameters involved in the economic evaluation (discount rate, PV electricity selling price, inflation rate, price of PV devices etc.). The effects of these variations were investigated for a district of a city in the South Italy (Palermo) by means of a methodology appropriately defined to explore the architectural morphology of buildings and evaluate the solar potential of PV systems installed on roofs. The results of the analysis provide the trend of the actual coverage of the district power demand from June 2010 to March 2011. Finally, a sensitivity an…
The evolution of the FIT mechanism in Italy for PV systems: a critical analysis
2013
The paper presents an analysis of the Feed'in Tariffs (FIT) mechanism development in Italy from 2005 to 2013 and named “Conto Energia”. In particular the work examines the five editions of the “Conto Energia”, highlighting both advantages and critical issues for the PV market development in Italy; this analysis is particular interesting due to the fact that the cap on FITs in Italy has been reached in June 2013.
Economic analysis of different supporting policies for the production of electrical energy by solar photovoltaics in eastern European Union countries
2010
Today, photovoltaic (PV) attracts considerable interest in relation to renewable energy technologies, because of its potential to contribute significantly to the future of renewable energy. However, PV market development is related strongly to the support policies introduced by national governments, defined in national laws. The modification or fading out of such incentive schemes can strongly influence the development of the PV market in any given country. In this paper, after a brief review of national support policies in PV technology in eastern European Union (EU) countries, the authors perform an economic analysis of the main support mechanisms that are implemented in these countries. …
Economical Analysis of Financial Supports for Large-Scale Photovoltaic PV plants in Eastern Europeen Union Countries
2010
Today, photovoltaic (PV) attracts considerable interest among renewable energy sources (RES), because of its potential to significantly contribute to the future of clean energies. However, PV development is strongly related to the support policies introduced by national governments. The modification or fading out of such support schemes can strongly influence the development of the PV market in any given country. Although the PV market in European developing countries is still quite small, it has been growing rapidly in recent years. Until 2006, the installation of small off-grid PV plants prevailed in eastern EU countries. Starting from 2008, large-scale on-grid PV plants have been put int…
An experimental analysis of power quality in presence of single phase grid connected photovoltaic systems
2004
In this paper, an experimental power quality analysis in presence of single phase grid connected PV systems is performed in a PV system installed at the Department of Electric Engineering of the University of Palermo through a measurement system set up by the Authors. In particular the analysis has been carried out focusing the attention on voltage and current distortion, as the solar radiation varies. The corresponding Total Harmonic Distortions in voltage and current terms are reported and compared with the standards limits. The presence of interharmonic components is also discussed.
ECONOMIC ANALYSIS OF SUPPORT POLICIES IN PHOTOVOLTAIC SYSTEMS: A COMPARISON BETWEEN THE TWO MAIN EUROPEAN MARKETS
2014
The development of the photovoltaic (PV) sector in the last decade was spurred by the implementation of various support strategies aimed at reducing the gap between PV energy cost and the energy price for conventional generation. The deployment of support policies has pushed the reduction of PV energy costs, but despite this PV is still not very competitive and its development still requires adequate support mechanisms, simple grid connection procedures, and so on. This chapter provides a technical-economic analysis of investments in PV systems, evaluating the positioning of the main European markets (Germany and Italy), with the purpose of highlighting the main differences in the implement…
The possibility of applying combined heat and power microgrid model for industrial parks. A case study for Dong Nam industrial park in Vietnam
2023
Microgrid systems that combine cooling, heating and power (CHP) with distributed cogeneration units and renewable energy sources are a practical way to meet the growing need for energy, and industrial parks have enormous potential for the development of integrated electrical and thermal systems. This paper presents a microgrid CHP model and evaluates the possibility of developing the model in the Dong Nam industrial park in Ho Chi Minh City, Vietnam. HOMER software was used to evaluate the effectiveness of the model.
An analysis of feed’in tariffs for solar PV in six representative countries of the European Union
2014
Abstract In this paper, after a brief review on the main support policies for Photovoltaic (PV) systems in Europe, the specific situations of six representative countries (France, Germany, Greece, Italy, Spain and the U.K.) are examined, with the purpose of highlighting the main differences in the implementation of the feed’in tariff (FiT) support policies adopted for PV systems. In particular, a comparison based on the calculation of economic indexes, as the Discounted Cash Flows (DCF), the Pay-Back-Period (PBP), the Net Present Value (NPV) and the Internal Rate of Return (IRR), for different sized PV systems shows that a specific FiT can sometimes be inconvenient for the producer and that…
Comparative analysis of different supporting measures for the production of electrical energy by solar PV and Wind systems: Four representative Europ…
2009
Abstract In the 9th of March 2007, the European Council decided a fixing goal of 20% contribution of the renewable energy sources (RES) on the total European electric energy production in 2020. In order to reach such an ambitious goal, all the European countries are adopting different support policies for encouraging the installations of RES-based generation systems. In this paper, after a brief review on the main support policies for RES in Europe, the specific situations of four representative countries (France, Germany, Italy and Spain) are examined, with the purpose of putting into evidence the main differences in the support policies adopted for Photovoltaic (PV) and Wind systems. In p…
Feed-in Tariffs for Grid-connected PV Systems: The Situation in the European Community
2007
Distributed generation demonstrates to be able to significantly influence the electric power system bringing considerable benefits to the quality of service and improving the energetic efficiency of the distribution network. In particular, in the last few years, distributed generation from renewable sources is considerably increased thanks to the many support policies promoted worldwide with the aim of facing the environmental issue and the problem of the permanent rise of prices of the fossil energy. In this contest the paper presents a study of the "feed-in tariffs" financing measure carried out, at present, in many European countries and responsible of the increase in these last years of…
