I comunicated ideas and points with my group during the lab and during the poster to better understand it. I introduced ideas that would make the poster look nicer with better sticky notes that were colorful and i talked to them about wh was doing what for the poster so everyone had something to do and no one was left with

SAM has three different choices for the user to choose from to modeling a photovoltaic system; The PVWatts System model which is an implementation of NREL 's online photovoltaic calculator, the Flat Plate PV model which combines and separates module’s component models that are available for the user to select and; and the High-X Concentrating PV model which is for concentrating PV systems. All three

The power conversion efficiency is evaluated with respect to standard reporting conditions (SRC) defined by temperature, spectral irradiance, and total irradiance. 23 The SRC for rating the performance of terrestrial PV cells are the following: 1000 W∙m-2 irradiance, AM 1.5 (AM: air mass) global reference spectrum, and 25 °C cell temperature. 24-28 The PCE (η) of a PV cell is given as30

 The basic objective of this paper is to extract maximum power and to maintain power quality to a satisfactory level from the varying condition the Photovoltaic array with different solar irradiation.

The voltage generated by single PV cell is low so we connect single PV cells in series when we need high voltage and in parallel when we need high current and thus we can get the high power or desired output. We generally use a series connection and this arrangement is called as Photovoltaic module or PV module. PV module generally consists of front side, back side and encapsulated PV cell. The front side of the material is made up of tempered glass and low iron. Efficiency is less in PV module because some of the radiation is reflected by glass cover. Basic PV cell can be seen below

Abstract: Photovoltaic (PV) based distributed generators (DGs) are generally controlled as current source to deliver only active power generated by PV source to the grid. However, reactive power transfer capability of such DGs must be utilized to satisfy reactive power demand of the load or to provide reactive power support to the grid. Reactive power management for several such PV based DGs operating in parallel is a challenging task as the available reactive power capacity of each depends on the environmental conditions and may vary continuously. The proposed algorithm considers the effect of environmental conditions on the active power generated by the DGs and accordingly assigns reactive power references for the inverters after computing the available capacity of the inverters. Hence, irrespective of variation in active powers of the DGs, the proposed algorithm not only helps to avoid the overloading of the inverters but also operates all inverters at same apparent power rating to ensure equal utilization of the inverters. The algorithm is evaluated in terms of its capability to obtain the best solution that gives the least standard deviation of utilization factors of the inverters. Simulation results obtained using MATLAB/Simulink are included to confirm its effectiveness over other algorithms.

Abstract- This paper presents a thorough comparative analysis study for various kinds of single diode models based photovoltaic power source. The main target behind the paper is to explore the effect of increasing the embedded degree of complexity of the single diode model on the simulated behavior of a particular PV module by comparing the dynamic performance of such kind of PV models with the experimental data from manufacturer 's data sheet under varying the atmospheric conditions. The relative errors between each PV single diode model output and the experimentally validated data are computed at three indicative points namely open circuit voltage, short circuit current and maximum power point. The result of this comparison leads to determining the best PV single diode module - that is more suitable than the others in the context of single diode model - to be applied in different power system application irrespective of changing the environmental conditions along over different periods of the day. The comparison study in this paper ends up with determining the relevant single diode model at low, medium and high temperature and irradiance level as well as at standard test conditions.

A photovoltaic (PV) array is a power system designed to supply usable solar energy by means of photovoltaics. It consists of an arrangement of several components, including solar panels to absorb and convert sunlight into electricity. Solar energy is radiant light and heat from the sun that is harnessed and used especially in the field of power generation. One of the major sources of renewable energy at present times, solar energy has been of interest throughout the world particularly due to its availability in significant magnitude in comparison to other renewable sources.

In recent years, Energy comes from natural resources such as sunlight, wind, rain, tides and geothermal heat. These resources are renewable. Therefore, for all practical purposes, these resources can be considered to be unlimited, unlike dwindling conventional fossil fuels. The renewable energy sources are known to be much cleaner and produce energy without the harmful effects of pollution unlike their conventional counterparts. Solar energy is converted into electrical energy and the electrical power generation in PV systems is highly affected by the temperature and the insolation level which makes it impractical to directly connect them to the load without any storage devices or utility grid interface. The PV systems focused on the minimization of the installation costs and the maximization of the energy capture and conversion efficiency. In order to maximize the conversion efficiency, the PV system should be operated at its maximum power point (MPP). This power is supplied to the load using parallel power processing topology to reduce the amount of power processed through the converter and, hence, decrease the converter size and increase the efficiency by means of direct energy transfer (DET).The concept of the PPP topology is shown in Figure.

Photovoltaic cell is affected by two major external conditions which are irradiance and temperature, the two factors have a great effect on the Photovoltaic cell and its output, the amount of power obtained from the PV system is a function of the PV array voltage and current set point, which brings to note why the output from the Photovoltaic cell has to be maximized with a DC booster.

Energy is the convertible currency of technology. Without energy the whole fabric of society as we know it would crumble; the effect of a 24 hour cut in electricity supplies to a city shows how totally dependent we are on that particularly useful form of energy. Computers and lifts cease to function, hospitals sink to a care and maintenance level and the lights go out. As populations grow, many faster than the average 2%, the need for more and more energy is exacerbated. Enhanced lifestyle and energy demand rise together and the wealthy industrialized economies which contain 25% of the world 's population consume 75% of the world 's energy supply [1]. The use of new efficient photovoltaic solar cells (PVSCs) has emerged as an alternative measure of renewable green power, energy conservation and demand-side management [2]. Renewable energy is the only hope and it is the area of latest research which needs a revolution to make an effective solar panel charging system for the regulation of the flow of current to the desired output and saving the battery from receiving extra voltage and increasing the life. 2. Modelling of PV Cell PV generators are neither constant voltage sources nor current sources but can be approximated as current generators with dependant voltage sources [3]. During darkness, the solar cell is not an active device. It produces neither a current nor a voltage. However, if it is connected to an external supply (large

The tilt angle of solar panel strongly affects the electricity generation. To finding the annual maximum power output, three different angles have been calculated. 32.6° is the best angle for solar electricity generation in Yuma city. Setting at 32.6°, the solar farm can generate 23,983,400kWh per year from 56,000 solar modules. Furthermore, the solar farm footprint

Sun oriented power has demonstrated high potential as a source of energy as the figure 1 beneath shows. Right now, a board can harness around 16% of the energy that falls on the surface of the board. The pv boards are in this way unsustainable considering there is more than 84% wastage (Sokona, Pichs-Madruga, and Edenhofer, 2012). But, the energy created utilizing the boards are adequate to help industries.The researcher’s put the production projection high when the panels will have the ability to harness over 80%

The aim of this literature review is to review other scholar 's literature in the area of new energy application on electricity, with a focus of solar panel, and compare with the traditional electricity supply and generate(analysis). Finally, the adopted academic literatures will be reviewed at the end of this part.

The climatic condition in India provides abundant potential of solar power due to large scale radiation available during a wider part of the year due to tropical condition in the country. The solar power can be developed for long term use through the application of solar photo- voltaic (SPV) Technology which
