Solar Radiation is considered as an important parameter in modeling environmental, hydrologic and biophysical processes. One of the reasons that solar radiations are not extensively used in models is the problem of its measurement in different points. Solar Analyst Viewshed Algorithm makes possible calculation of the topographic effects on solar radiation at local and landscape scales. With res...

Increasingly, using lower energy cost system to overcome the need of human beings is of interest in today's energy conservation environment. To address the solution, several approaches have been undertaken in past. Where, renewable energy sources such as photovoltaic systems are one of the suitable options that will study in this paper. Furthermore, significant work has been carried out in the ...

The utilization of a cuk converter for control of photovoltaic power using Maximum Power Point Tracking (MPPT) control mechanism is presented in this paper. The main aim of the project is to use cuk converter along with a Maximum Power Point Tracking control mechanism. The MPPT is responsible for extracting the maximum possible power from the photovoltaic panel and feeding it to the load via th...

In accordance with the specifications for the design of the gas station lighting system, the original lighting system was transformed into the overall solar-powered LED lighting system. The original lighting was replaced by using the same illumination LED lamps. Calculations were made to determine the optimum tilt angle of solar components. Based on the reasonable LOLP rate, solar module and ba...

This paper deals with the analysis, design and control of a small power standalone solar photovoltaic (SPV) generating system. A PV array of 33V-43.2V is taken as an input and its output voltage is achieved as 360V dc using a flyback converter. The battery is charged at this voltage and using a single-phase voltage source inverter (VSI) it is converted into a single phase ac of 220Vac, 50 Hz. A...

We present the development of a dynamic software simulation environment for modelling small and large scale photovoltaic (PV) energy generation systems. The model elements of solar panels, Maximum Power Point Trackers (MPPT) and solar inverters were integrated to a simulator system providing weather and power grid models as well as simulation of combustion power plants. The integrated system en...

The amount of the conventional energy sources is decreasing day by day. Here in Bangladesh, the main source of energy generation is natural gas. To avoid the upcoming energy crisis, we need to incorporate the renewable energy sources with which Bangladesh is blessed due to its geographical location. Bangladesh has a very good prospect for the solar Photovoltaic integration. The technical potent...

Photovoltaic solar energy has been gaining market share over the years due to lower prices and to a significant incentive from the government. It is a clean, static and promising energy source, and such technology has been applied to various applications. This paper presents a prototype of an automated irrigation system for later installation on the field. After the prototype development, we an...

The output power produced by high-concentration solar thermal and photovoltaic systems is directly related to the amount of solar energy acquired by the System, and it is therefore necessary to track the sun’s position with a high degree of accuracy. This paper presents sun tracking generating power system designed and implemented in real time. A tracking mechanism composed of photovoltaic modu...
