Future Expectation of the Photovoltaics Role in Compensating Energy Demand

Abstract

Photovoltaics (PV) is becoming a mainstream electricity provider and the need for PV cells will spike compared to current demand. Solar power is based on obtaining electricity from solar radiation by using either photovoltaic cells or concentrated solar power (CSP). Both systems have different requirement to the area and advantages. However, there are several common disadvantages, which are related to the initial cost and regulatory issues that prevent investors from starting up such projects. Based on these premises the utilization of the solar power was examined in this study by highlighting the world's sustainable energy potential and investment statistics. Therefore research analysis related to the solar energy potential is presented as well. Although, the sustainable energy is the future of the world and requires slightly less amount of expense after installation, compared to conventional energy sources, the installation costs are the predominant factor of the utilization of the sustainable energy technologies. Furthermore, this study makes an overview of the world's solar power capacity today and makes prediction for the future. This study presents comprehensive market data together with forecasts for the short-run, while the role of PV is discussed considering the demand of energy.

A Study of Evaluation of Solar Energy Simulation and Modeling Systems

“…As to benefit effectively of radiations, there are two of fundamental terms of solar energy necessary for accurate prediction of the Sun position described by the angles: the solar altitude and the solar azimuth. Above these two angles the declination angle and hour angle need to be defined [1,2,8]. The azimuth displayed is the horizontal direction of the Sun at sunrise and sunset, since the times used for the sunrise and sunset calculations are also used for azimuth calculation.…”

“…This is accomplished in this study of explaining parameters needed to calculate the position of the sun in the sky. To assess the availability of solar radiation at different locations, measurements of global radiation, diffuse radiation, beam radiation, sun shine hours, bright sun shine hours, maximum and minimum temperature, humidity, pressure, visibility, wind speed and direction, gust speed, water precipitation, and air mass are very important parameters [8][9][10]. In this study the calculations has been computed by the algorithm that has been developed in C# to determine solar angles due to the given location and date.…”

A Review of MPPT Algorithms for Partial Shading Conditions

“…Solar energy is one of the promising renewable types of energy, which is coming from an unlimited solar source -the Sun and can be directly converted to electrical energy by photovoltaic (PV) modules [2,3]. PV cells have non-linear characteristics which are affected by irradiance level, temperature, total residence etc.…”

Experimental Study of Degradation Modes and Their Effects on Reliability of Photovoltaic Modules after 12 Years of Field Operation in the Steppe Region

“…With the developing technology, the rapid increase of world population causes an increase of energy consumption [1]. Photovoltaics (PV) is becoming a mainstream electricity provider and the need for PV cells will spike compared to current demand [2]. The PV module is the main part of a solar PV system because it transforms the solar radiation into electricity.…”
