Abstract

In this article, the future in photovoltaic energy productivity (PVE) is evaluated using climate variables simulated aerosol clearness index and solar irradiance, it is a model for the performance of photovoltaic systems. The analysis indicates that the aerosol emission reductions in the near future result in an increase in global warming with a significant response of the solar surface radiation and associated PVE productivity. Changes in radiation surface and productivity of solar PVE are related to overall reduction in aerosol effects on the circulation and large scale associated with cloud coverage pattern, rather than local atmospheric effects on optical properties. PVE evaluation is then discussed in the context of the current situation and the PV market highlighting the effects on productivity induced by industrial and public policies, while technological development are comparable to the effects related to the weather. The results presented encourage the improvement and further use of climate models in the assessment of future availability for renewable energy.

Highlights

Photovoltaic systems allow the conversion of solar energy into electricity from sunlight, it is the growing demand for electricity worldwide and one of the sustainable solution alternatives
The total percentage deviation of expected temperature is less than 5.25% for MRL and 4.53% for Principal components of regression (PCR) in this study
It can be concluded that the predicted temperature accuracy is adequate for renewable solar energy applications and can be used in the study area and in tropical areas with similar climatic conditions where the variables remain relatively constant throughout the day

Summary

Introduction

Photovoltaic systems allow the conversion of solar energy into electricity from sunlight, it is the growing demand for electricity worldwide and one of the sustainable solution alternatives. In other experimental investigations like in the works of Ryu et al (2006) and Wu et al (2012), different configurations of solar photovoltaic concentration systems using Fresnel lenses have been proposed and tested under different operating parameters such as solar radiation intensity, ambient air temperature and natural and forced convection. Another new technology in which high flux photovoltaic cells were used for different solar cell concentrator designs was proposed by Feuermann and Gordon (2001). The same techniques can be incorporated into improved photovoltaic performance models of more accurate energy efficiency forecasts
