The photovoltaic (PV) systems should operate at a maximum power point (MPP) to extract the maximum possible output power with high tracking efficiency under various operating conditions This paper discusses a new maximum power point tracking (MPPT) technique to extract the peak power from the PV...

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.

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...

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 is the first of three planned quarterly Technical Reports of 1996 system performance and major project activities. The final quarter will be discussed in the 1996 Progress Report. Activity for the PVUSA project was curtailed considerably, pending resolution of the transfer of management to...

A new method for estimating the irradiance on a partially shaded photovoltaic generator system is proposed. The basic principle of this method consists of two parts: firstly, an approximation of the obstacles’ outline or the local horizon by a set of linear functions. Here, a survey of the...
