There is now a growing body of evidence that challenges the current view that Plasmodium vivax-infected erythrocyte (Pv-iE) are unable to sequester. Here we used ex vivo adhesion assays with Pv-iE before and after maturation to demonstrate a higher binding potential of schizonts compared to other asexual stages. These experimental results are correlated with our observations in a panel of 50 vi...

This paper presents a computational approach to forecast photovoltaic (PV) power in kW based on a neural network linkage of publicly available cloud cover data and on-site solar irradiance sensor data. We also describe a control approach to utilize rooftop air conditioning units (RTUs) to support renewable integration. The PV forecasting method is validated using data from a rooftop PV panel in...

School of Electrical Engineering, VIT University. Vellore – 632014. Tamilnadu. India In this paper, we present a novel maximum power point tracking method for a photovoltaic system consisting of a photovoltaic panel with a power electronic converter; the whole is feeding a battery. This maximum power point depends on the temperature and irradiation conditions. A robust control using a PI regula...

For many years, the photovoltaics (PV) community has relied on the concept of energy payback time (EPT) as a means of quantifying the ratio of energy generated from a PV panel or system over its lifetime, compared to the energy that was required to fabricate it. Few other energy technologies are so judged and this paper argues that the EPT concept is obsolete, misleading and may possibly even c...

This paper presents the dynamic simulation model to characterize water pumping and heating installation using PV/Thermal panel (PV/T) is developed. The model consists of a set of mathematical equations governing the main components of the system; namely: transparent cover, solar cell, absorber plate and operating fluid. The model is based on the analysis of the energy balance which includes the...

The paper describes the design, simulation and practical implementation of a PV system specifically designed for battery charging applications. A DC-DC synchronous Buck converter is digitally controlled by a dsPIC33F to extract the maximum power from the PV panel and feed it to the battery, according to the data received through the sensors. The system proves to be stable to rapid weather chang...

The aim of this paper is to design a textual display system, based on a light emitting diode (LED) dot matrix array powered by solar energy. The paper involves taking the device from an initial concept, through a design phase, to constructing a prototype of the product. The system consists of the display unit, which is powered from a photovoltaic ( PV) module and a solar sealed lead acid batter...

Photovoltaic (PV) cell converts sunrays into electrical energy, which has non-linear I-V characteristics. For extracting maximum power from photovoltaic (PV) array for varying environmental conditions, it is necessary to use MPPT tracker. The MPPT consists of DC-DC converter and MPPT algorithm, DC-DC converter is inserted between solar panel and load or battery. The task of MPPT tracker is to m...

The PV market is still expanding causing the situation in PV industry becoming more and more complex. Different cell types emerge on the market provided by a growing number of cell suppliers. Due to silicon shortage in the past solar cells were getting significantly thinner within the past few years. All these parameters have a potential impact on the mechanical stability of a solar panel. This...

Solar photovoltaic system performance depends on environmental conditions. Solar photovoltaic panel is a power source having nonlinear internal resistance. As the intensity of light falling on the panel varies, its voltage as well as its internal resistance both varies. To extract maximum power from the panel, the load resistance should be equal to the internal resistance of the panel. This pap...
