Abstract
The growing demand for local pollution free renewable energy sources in the world considered the solar energy as a one of the important renewable energy technologies and becomes dominant to the renewable energy source being exploited. The paper presents a unique approach to study and analysis off-grid photovoltaic (PV) system in order to provide the required energy for a one fold household in Diyala State, Iraq as well as the CO2 emissions and life cycle (LCC) and economical aspect was considered. The results of the study by depending on site metrological data shows that the unit of electrical cost of (1 kWh) about ($0.51) and this value is not expensive compared to the current unit cost of electricity and becomes effect and encouraged the use the PV system to electrify the rare sites. The average of CO2 emissions get avoidance about 1840 kg/year compared with conventional fuels used in Iraq to generate electricity.
Highlights
The global challenge to get green energy from reliable and cost-effective services remains one of the major challenges facing the world in this century
The PV energy systems received more interest because of like these systems can overcome the intermittent nature of renewable energy sources, the over-sizing issue and enhance reliability of supply
According to present study the generating of 14 kWh/day by using natural gas produce 6.1 kg/day and at the same time it produce 1.3 kg/day by using a PV system get avoidance in CO2 emissions about 1840 kg/year compared with conventional fuels used in Iraq to generate electricity
Summary
The global challenge to get green energy from reliable and cost-effective services remains one of the major challenges facing the world in this century. Reliance on a single technology generally results in an over-sizing of the system, thereby increasing the initial costs. Often advanced fuel systems such as hydrogen are considered. Examples of such studies include the following Khan and Iqbal [3] who investigated the feasibility of a hybrid system with hydrogen as an energy carrier in Newfoundland, Canada; Barsoum and Vacent [5]; Karakoulidis et al [6], Giatrakos et al [7] and Türkay and Telli [8]
