This paper presents a case study on the utilisation of global solar radiation data on horizontal surface to perform an economic feasibility study of using Photovoltaic (PV) panels with battery backup to meet a small load for a camping site in Saudi Arabia. The analysis considers three scenarios...

Photovoltaic technology is used worldwide to provide reliable and cost-effective electricity for industrial, commercial, residential and community applications. The average lifetime of PV modules can be expected to be more than 25 years. The disposal of PV systems will become a problem in view...

Solar energy is a clean source of energy that is available in all regions of the world. Bahrain, where the present research was conducted, is rich in solar energy expressed as hours of sunshine which ranges between 13 h per day in the summer months to 10 h per day in the winter months.

The main problem in using photovoltaic (PV) systems is the low energy conversion efficiency of PV cells. The efficiency of PV cells will decrease significantly as the temperature of the cells exceed to a certain limit. In order to increase the efficiency, it is necessary to reduce the operating...

This article presents a novel MPPT (maximum power point tracking) algorithm, based on a modified GA (genetic algorithm). When photovoltaic systems are affected by partial shading, a GMPPT (global maximum power point tracking) algorithm is required to increase the energy harvesting capability of...

Partial shading decreases the power output of PV arrays due to mismatch losses. These losses are dependent on the shading pattern and the relative positions of shaded modules in the array. Various static and dynamic reconfiguration techniques have earlier been proposed to mitigate these losses....

As photovoltaic (PV) system suffers considerable energy loss due to partial shading (PS), various approaches have been proposed to mitigate this problem. Among these, improving the maximum power point tracker (MPPT) algorithm seems to be the most feasible and economical solution. To date, there...

This paper presents a review on the state-of-the-art maximum power point tracking (MPPT) techniques for PV power system applications. The main techniques that will be deliberated are the Perturb and Observe, Incremental Conductance and Hill Climbing. The coverage will also encompass their...

This work presents a new analytical method to evaluate the efficiency of PV systems working in partial shading conditions by taking into account the effect of surrounding obstacles. A mathematical procedure to determine the shadowed area on PV modules, depending on the location of the PV system...
