Abstract The promotion of large photovoltaics projects is a trendy reality in South America, but the potential to be a solution for distributed generation through small-medium systems connected to the grid is an under-exploited reality. In this paper, a techno-economic analysis of three small PV systems located in different cities of Peru is undertaken. Based on real measured energy data, two different scenarios are going to be economically evaluated: one that resembles a lease contract and anot...

Nowadays, the integration of photovoltaic (PV) systems into the grid involves new and competitive ways to realize this. Thus, it is necessary to define procedures that not only include energy calculations but also incorporate economic and funding feasibility features. According to the literature review, there are numerous tools that are available to carry out a profitability analysis of a photovoltaic system. However, certain shortcomings have been identified, either in the definition of the eco...

Operation and Maintenance (O&M) tasks are becoming increasingly important in the asset management of photovoltaic projects. However, there is insufficient evidence to analyse in depth its influence on the energy and economic performance of such systems. The wide range of O&M annual expenditures (OPEX) and the lack of standardization further complicate the proliferation of specialized studies. This paper analyses the influence of OPEX on the performance and viability of a utility-scale photovolta...

Abstract The idea of combining both thermal and photovoltaic collectors in hybrid photovoltaic-thermal (PV-T) modules actually shows a great potential for integration on facades and rooftops of buildings, mainly because of the reduced available space and the benefits of the on-site electricity and thermal generation. The objective of this work is to compare the real performance (experimental data obtained under real sun during a year) of a commercial hybrid PV-T system vs. a simple PV system usi...

Tracing the characteristic I-V curve of any photovoltaic device is the essential experiment that allows us to obtain reliable information about its state and behavior. Therefore, it must be part of the practical content in any Bachelor's, Master's or PhD degree that teaches the students in the photovoltaic systems engineering field. This paper presents the progress-achievements of two research groups -from Argentina and Spain- in the design of electronic prototypes or ad-hoc systems that carried...

The Spanish photovoltaic industry was stunningly successful during 2007–2010, fostered by a favourable feed-in tariff system. Nevertheless, the cost overrun of this promotion policy led to government legislation against existing PV plants. Although these investments will be profitable when the subsidy ends, according to the last law enacted in Spain (IRR = 7.4%), either a massive sale to vulture funds or the abandonment of PV plants is being planned. Owners are unable to cover the loans through ...

Abstract The spectrum is not frequently used when rating any PV technology. Moreover, in those energy predictions where it is considered, normally they are based on simulated models. The objective of this work is the spectral characterization of the solar resource based on real measurements as their availability in the scientific community is scarce. For this characterization the Average Photon Energy is used, which has been obtained from an experimental campaign carried out in Jaen (Spain) base...
