Improvement of perturb and observe MPPT method for photovoltaic systems: case of study
Maximum power point tracking system is widely used to maximise output power of photovoltaic array. A crucial issue of this system is an algorithm of maximum power point seeking. Well–known perturb and observe technique is optimal solution in terms of the ratio of cost and efficiency. However, this algorithm has some disadvantages such as oscillation around a maximum power point and decrease in ...

Developing MATLAB software for PV and battery sizing for lighting projects in Gaza Strip, Palestine
Recently, with the critical situation of the siege on the Gaza Strip, the need for an alternative energy source instead of traditional energy sources increases day by day, especially as Palestine is considered one of the sunny countries and receives good solar radiation over the year. In this paper, the MATLAB software is developed for sizing process of PV modules and batteries. The developed ...

The techno-economic and environmental aspects of a hybrid PV-diesel-battery power system for remote farm houses
In this study, the solar radiation data of Balikesir in Turkey are analysed to assess the techno-economic viability and environmental performance of a hybrid Photovoltaic (PV)-diesel-battery system to meet the load requirements of a typical remote farm house. Several aspects of the system are studied through the Cost of Energy (CoE), the operational hours of diesel generator, unmet load, excess ...

The keys to saving energy thanks to the sun
Today, more than ever, we are looking for ways to lower our energy bills while also reducing our impact on the planet. One of the best solutions that we have in Spain is the use of solar energy. In fact, one of Spain's strengths is its large number of sunny days throughout the year: a strength that becomes a real advantage in terms of energy generation and savings. But, what data should we take ...

Photovoltaic technology of electricity generation for desert camping
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 with daily average energy demands: (a) full load, (b) 75% load, and (c) half load, with annual peak ...

Harnessing the Sun`s Energy for Water and Space Heating
The pace of solar energy development is accelerating as the installation of rooftop solar water heaters takes off. Unlike solar photovoltaic (PV) panels that convert solar radiation into electricity, these "solar thermal collectors" use the sun's energy to heat water, space, or both. China had an estimated 168 million square meters (1.8 billion square feet) of rooftop solar thermal collectors ...

Solar Power 2011 - Solar PV Breaks Records in 2010
Solar photovoltaic (PV) companies manufactured a record 24,000 megawatts of PV cells worldwide in 2010, more than doubling their 2009 output. Annual PV production has grown nearly 100-fold since 2000, when just 277 megawatts of cells were made. Newly installed PV also set a record in 2010, as 16,600 megawatts were installed in more than 100 countries. This brought the total worldwide capacity ...

Characteristics of solar radiation sensor
Introduction:A solar radiation sensor, also known as a pyranometer, is a device that measures the amount of solar radiation received on a surface in a given time period. Solar radiation is the energy that is transmitted by the sun to the earth, and it is measured in watts per square meter (W/m²). The solar radiation sensor provides valuable information for various applications, including ...
