Worldwide requirement of energy is presently increasing beyond the capacity of generation. To fulfilling the upcoming energy needs effectively, generation of energy need to be enhanced and sustainable energy sources should be examined insistently. Compelling energy arrangements have the option to address future problems by using the alternative sustainable power sources. Apart from several renewable sources, solar energy is clearly a capable choice because of its accessibility. Solar power, particularly as it arrives at increasingly serious levels comparing to remaining sources of energy as far as cost, may provide to continue a lives of lots of oppressed individuals into the developing nations. Additionally, solar energy equipments are able to promote an economy and atmosphere of developing nations. Solar energy is primarily used for heat and power generation. International energy agency (WA) appears, into a relative report on global energy utilization that into the year 2050 solar arrays installation will give around 45% of global demand. Solar energy is supposed to be significant sustainable power sources which assume an extraordinary position while giving energy arrangements. Most of the researches have been completed on the solar rays capturing technology and lots of work is still undergoing. But apart from these, limited research was carried out on the solar mounting structures and various mounting technology of the solar panel. This paper aimed to make a short review on the various available renewable energy sources along with solar energy and various mounting systems for the PV panels. [ABSTRACT FROM AUTHOR]

This research paper gives out the implementation of boost (step-up) converter and Z-source Inverter (ZSI) for solar Photo-Voltaic (PV) applications through Maximum Power Point Tracking (MPPT) control. Present energy demand mainly depends on renewable energy sources (RES). The Solar energy is best and the acceptable solution for increasing energy demand. To increase the dc voltage from the solar array, the boost converter is connected between the solar PV array and the Z-source Inverter (ZSI). The ZSI can be responsible to enhance the dc output voltage from the boost converter that can be given to load. MPPT algorithm is utilized for the generation of duty cycle and the triggering pulse for the boost (step-up) converter. The Simple Boost (SB) PWM control algorithm is used for the ZSI. The modelling and simulation of the boost converter and ZSI are presented. The simulation results are obtained by considering the 1Soltech 1STH-215-P solar array model in Matlab and simulation results are validated. [ABSTRACT FROM AUTHOR]

A solar-powered unmanned aerial vehicle (UAV) is powered by solar cells installed onboard which capture solar energy during daylight. Such generated power is supplied to the motor to propel the aircraft and other electronics or to recharge the battery on board. Solar-powered UAVs are used for long-term service missions at very low costs. This paper presents the generation of the low energy flight path for a small 5.5 kg hand-launchable low-altitude long-endurance (LALE) solar-powered UAV. The goal of the proposed work is to decrease the energy consumption of aircraft to increase endurance by using the optimal climb angle and the minimum sink rate glide. A climb and glide phase energy optimization with the validation of surplus solar energy to satisfy the energy consumption has been proposed. [ABSTRACT FROM AUTHOR]

The essentiality of electricity in today's world is increasing for the mankind. The need of electricity is only increasing day to day while the fossil fuels for generating the electricity is decreasing. The generation of energy can only be met by depending on solar energy. In current scenario of energy generation among the usage of renewable energy resources, solar energy stands at the top. While the solar energy is abundant, harnessing the electric energy is challenging. The size and number of PV cells is ever increasing to harness more energy while there are certain factors that can be considered to increase the efficiency of the PV system. The paper describes one such technique in which the PV panels are rotated according to the motion of the sun to receive maximum intensity of light which in turn increases the generation of the energy. Also, the dust on the panel, which has the impact on efficiency of the panel, is monitored and cleaned. [ABSTRACT FROM AUTHOR]

Now-a-days, power from Sun (solar light) is generated universally. At present, there is a claim of clean energy and we can get a great amountof power from sun. Energy from sun is boundless andhuge amount of energy (heat and light) falls on ground per day andif we can use that energy properly then there is a hope of satisfactoriness in energy. To get energy from sun, we use various kinds of solar cells. Solar cell converts light into electricity directly by using photovoltaic effect and there are many varieties of them. Solar cell is also well-known as photovoltaic cell (PV cell) and is used to switch sun's energy into electrical energy. Getting power from sun is considered as the solution of sustainable energy.But for that, we need to know how and where we can use solar energy and where it will be supplementary proficient to apply. In this paper, we have discussed about the types of solar cells and good things about solar concentrated tower. Mainly remarkable, to produce electricity, a block diagram has been discussed with some important applications to make this energy efficient in this paper. In the direction of gettinghuge power, only solar panel is not satisfying as solar power tower with mirror (solar energy concentrated tower) gives a large amount of power. So, in our block diagram, we are using both solar panel and solar concentrated tower as both solar panel and tower will be more efficient if connected together. [ABSTRACT FROM AUTHOR]

The paper examines the impact of the humidity on the Solar panels which makes a space for the drastic variation in the power generated and makes the device less efficient. Humidity readily affects the efficiency of the solar cells and creates a minimal layer of water on its surface. It also decreases the efficiency by 10-20% of the total power output produced. Moreover, to handle this issue, all around characterized measures are required to be taken to guarantee the smooth working of the solar panels utilized in humid areas. In connection with this issue, Karachi, the biggest city of Pakistan which is located near the costal line touching Arabian Sea, was taken as a reference city to measure the humidity range. In Karachi, the average humidity lies between 25-70% (as per Pakistan Meteorological Department PMD), that indirectly leads in decreasing power acquired from a Solar Panel and develops various complexities for the solar system. The system on average experiences stability issues, such as those of power fluctuations etc., due to which, the whole solar system installed observes abnormal variations in acquired power. Silica Gel was used as a desiccant material in order to assure dryness over the solar panel. More than four experiments were conducted with the usage of water absorbent to improve the efficiency and to make system more power efficient. [ABSTRACT FROM AUTHOR]
