Six-years-long effects of the Italian policies for photovoltaics on the grid parity of grid-connected photovoltaic systems installed in urban contexts
2017
Abstract The purpose of this study is investigating the grid parity (GP) time and the levelized cost of energy (LCOE) of grid-connected photovoltaic (PV) systems installed in densely urbanized contexts. The analysis, which was elaborated for three Italian cities, considered the effects of the promoting policies enacted by the Italian government from June 2010 to May 2016. An appropriate methodology was applied with the aim of realistically defining the energy produced by PV systems installed on buildings with different roof types and number of floors. The calculus of the disbursements considered the operating, maintenance and insurance costs and the wear of PV panels and inverters. The resu…
Financial measures for supporting wind power systems in Europe: A comparison between green tags and feed’in tariffs
2008
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 energy 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, after a brief review on the financing strategies carried out in Europe in the last decade for promoting the recourse to renewable energy, the paper presents a comparis…
Six-years-long effects of the Italian policies for photovoltaics on the pay-back period of grid-connected PV systems installed in urban contexts
2017
Abstract In this study the discounted pay-back (DPB) period of rooftop photovoltaic (PV) systems installed in urban contexts was investigated during the course of time with the aim of evaluating the effects of the different supporting policies enacted by the Italian government. The profitability of the investment in three Italian cities was observed from June 2010 to May 2016 by means of an exhaustive economic analysis based on the study of the variation of the costs and benefits during the lifetime of the investment. The analysis considered the disbursements for the PV system devices, maintenance and management, insurance, and wear of PV panels and inverters. Other significant parameters, …
Assessment of Italian energy policy through the study of a photovoltaic investment on greenhouse
2013
The production of energy from renewable sources is a form of energy production that has less impact on the environment than the traditional one. For the farmer this new form of production represents an opportunity, especially for the economic benefits that can produce, both in terms of the incentives provided by the public operator and for higher revenues, deriving from the energy sale and/or the saving generated by self-consumed energy, that help to integrate the farmer’s income. In this paper, we analyzed a case study of a farm that has realized a grid-connected photovoltaic (PV) system on greenhouse. In particular, firstly the farm profitability and subsequently was estimated in order to…
The interaction between intermittent renewable energy and the electricity, heating and transport sectors
2012
In a global perspective, it is essential that the world transfers from fossil fuels to renewable energy sources in order to minimise climate change effects. As a part of such transition energy savings are also important, as they can decrease production costs effectively. The nature of such a change is that it has to be implemented on a local level. Energy saving technologies are placed with the demand decrease and renewable energy is typically distributed where the resources are. In some parts of the world, energy savings have resulted in a stabilisation of the energy demands, however in the world as such, demands are still increasing in buildings, transport and industry. Although the deman…
Renewable energy evaluation in Italy and Brazil
2017
The aim of this study is a comparison among Italian and Brazilian electrical energy system with a particular focus on renewable energy sources. The energy sector has a key role in the sustainable development of a country, so it influences economic and political choices. The work would underline differences, common point among two country, specially, in this particular socio-economic period and it should emphasize that green economy could be a possible answer to the financial crisis. The work will be divided into four sections: Section I will introduce all details of the question; Section II will explain the renewable assessments for the countries, Section III will talks how renewable energy…
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…

The recent change in the Italian policies for photovoltaics: Effects on the payback period and levelized cost of electricity of grid-connected photov…
2015
Abstract This paper provides an economic analysis of the investment in grid-connected PV (photovoltaic) systems installed on the rooftops of buildings located in densely urbanised contexts. The analysis was applied to some case studies that were selected as representative of the latitudes of the southern, central and northern Italy. The returns of the investment in PV systems were investigated with the aim of comparing the impact of the current PV policy, based on the tax credit scheme, with the FIT (feed-in tariff) scheme, in force until July 2013. The cash flows related to the disbursements and benefits during the lifetime of the investment were computed for each combination of orientatio…
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…
