Evaluation of Technical Feasibility and Economic Viability of Low Power Stand...Premier Publishers
Cost effective and hassle-free energy generation without causing environmental degradation is the need of the hour for saving mother earth and mankind from imminent devastation. Solar PV (SPV) energy generating systems are gifted solutions to overcome this acute problem. Energy generation using SPV systems is quite effective and efficient only if the SPV panels are aligned to be normal to the incident solar irradiation at all times during the day. This stringent requirement is fulfilled by mounting SPV panels on sun tracking systems. Single axis and dual axes sun tracking systems are widely used for generating a fairly good amount of energy by aligning the SPV panels to follow the sun throughout the day. This research paper presents experimental results and cost analysis to prove that a tilted single axis sun tracking system is a technically feasible and economically viable solution to this demanding requirement. Experimental investigation carried out over a period of one month during October,2016 has established that the energy gain of a tilted single axis sun tracking system turns out to be 31.91 % and that for a dual axes system is marginally more with just 35.3 %. Cost analysis of these systems has shown that the cost per kWh of generated energy for a tilted single axis sun tracking system is INR. 2.92and that for a dual axis tracking system is INR. 3.42, thus reiterating the fact that a tilted single axis sun tracking system can be used with advantage in low or medium power standalone SPV power generating systems.

Feasibility Study of Modified Quasi Z Source Inverter for Solar PV Technologyijtsrd
In recent years, Photovoltaic PV power generation systems have always been considered as an alternative energy source that can lighten the rapid consumption of fossil fuels. The current developments in the photovoltaic materials and power converters has emerged this as promising technology. A PV inverter is widely used to convert the photovoltaic energy into electrical energy as most of the demands are in AC voltage, either for local loads or supplied into the grid. Power converter topologies employed in the PV power generation systems are mainly characterized by single or multi stage inverters. The Z-source inverter ZSI has a single stage structure to achieve the voltage buck boost character in a single power conversion stage. The energy storage device integrated to Quasi Z-source inverter QZSI topology eliminates need for an extra charging circuit. This upgraded topology acquires the operating characteristics from the traditional ZSI, along with the capability of operating under very low PV power conditions. Its main operating points are classified into two modes, the low PV power mode, where the battery is discharged and the high power mode, where the battery is charge up. An extended input power operating range is achieved since the lack of Photovoltaic power can be compensated by the battery. Hence we can conclude that QZSI realize boost buck function in a single-stage with improved reliability, lower component rating, constant DC current from source and good power quality showing an efficient method for the energy-stored PV power generation Shwetha S Baligar | Chandrika S Kukanur | Chaitanya Krishna Jambotkar "Feasibility Study of Modified Quasi Z Source Inverter for Solar PV Technology" Published in International Journal of Trend in Scientific Research and Development (ijtsrd), ISSN: 2456-6470, Volume-2 | Issue-6 , October 2018, URL: http://www.ijtsrd.com/papers/ijtsrd18839.pdf

Experimental Analysis of Factors Affecting the Power Output of the PV Module IJECEIAES
Energy is the driving force in all the sectors as it acts like an index of standard of living or prosperity of the people of the country. However heavy dependence on fossil fuels leads to global warming, hence there is a need for the use of clean, sustainable, and eco friendly form of energy. Among the various types of non-conventional energy solar energy is the fundamental as it is abundant, pollution free and universally available.Even though the main input to the PV system is the solar radiation still there are other factors which affects the efficiency of the pv module. In this paper real time experiment has been conducted to analyze the effect of various factors like irradiance, temperature, and angle of tilt, soiling, shading on the power output of the pv module. Temperature is a negative factor which reduces the efficiency of the module and can be reduced by various cooling arrangements. Presence of dust particles and shading obstructs the incident solar radiations entering the panel and the effect is seen in the iv and pv curve .For better performance solar tracking at maximum power point is suggested to improve the power output of the pv module.

The advent of micro grid has enticed a lot of interest in the research of distribution generation thereby bringing into existence an intelligent electrical generation networks. It ensures security, reliability, stability, and sustainable of energy. Micro grid may include both renewable and non-renewable energy sources. It has been proven to possess the promising potential of providing clean, efficient, and reliable power. The energy sources include solar photovoltaic, wind, fuel cell, micro turbine, bio- mass micro hydro. Various architecture of a micro grid are available and are developed the factors dependable upon availability of renewable resources, geographical location, load demand. For effective and efficient operation unlike main grid, it needs to employ special and control this is so because of combination of conventional and renewable energy sources.
The significance of the solar energy is to intensify the effectiveness of the Solar Panel with the use of a primordial solar tracking system. Here we propounded a solar positioning system with the use of the global positioning system (GPS) , artificial neural network (ANN) and image processing (IP) . The azimuth angle of the sun is evaluated using GPS which provide latitude, date, longitude and time. The image processing used to find sun image through which centroid of sun is calculated and finally by comparing the centroid of sun with GPS quadrate to achieve optimum tracking point. Weather conditions and situation observed through AI decision making with the help of IP algorithms. The presented advance adaptation is analyzed and established via experimental effects which might be made available on the memory of the cloud carrier for systematization. The proposed system improve power gain by 59.21% and 10.32% compare to stable system (SS) and two-axis solar following system (TASF) respectively. The reduced tracking error of IoT based Two-axis solar following system (IoT-TASF) reduces their azimuth angle error by 0.20 degree.
This project aims to develop dual axis solar tracker with IOT monitoring system using Arduino. Generally, solar energy is the technology to get useful energy from sunlight. Solar energy has been used in many traditional technologies over the centuries and has been widely used in the absence of other energy supplies. Its usefulness is widespread when awareness of the cost of the environment and the supply is limited by other energy sources such as fuel. The solar tracking system is the most effective technology to improve the efficiency of solar panels by tracking and following the sun's movement. With the help of this system, solar panels can improve the way of sunlight detection so that more electricity can be collected as solar panels can maintain a sunny position. Thus the project discusses the development of two-axis solar-tracking developers using Arduino Uno as main controller the system. For develops this project, four light-dependent resistors (LDRs) have been used for sunlight detection and a maximum light intensity. Two servo motors have been used to rotate the solar panel according to the sun's light source detected by the LDR. Next a WIFI ESP8266 device is used as an intermediary between device and IOT monitoring system. The IOT monitoring system is a website that functions to store data. The efficiency of this system has been tested and compared with a single axial solar tracker. As a result, the two-axis solar tracking system generates more power, voltage and current.
Solar cells are a major alternate source of sustainable energy in the usual condition of depleting non- renewable energy sources. Nowadays, this source is getting more and more important due to its use in large and small-scale installations. One of the major causes of energy losses in photovoltaic (PV) modules is the shading. It can happen due to clouds passing, near trees, and/or neighboring structures. Generally, there are two types of PV module Shading which are either partial shading or complete shading. Both have a significant impact on the solar module output power. This paper is an attempt of carrying out a study of the electrical characteristics of a solar module with various percentages of simulated shading. The solar module tester (SMT) simulator was used in this study. The study approved the direct correlation between short-circuit current and solar irradiance. The advantage of using SMT is its stable irradiance in comparison to the practical unstable solar irradiance within the same period. The results of both methods of shading simulation show that shading has a significant impact on the performance of solar panel in terms of efficiency, fill factor and output power. For better performance, solar panels should install in shading free places as much as its possible.
Major depletion of fossil fuel and the increase of greenhouse gasses such as carbon dioxide, chloroflurocarbons (CFCs), hydroflurocarbon (HFCs), perflurocarbons (PFCs) and Sulphur hexafluoride (SF6) worldwide are the catalyst for the interest of many counties towards renewable energy. The rising cost of electricity due to higher demand and less resource also led to the renewable energy venture. One of the most famous renewable energy is solar energy. Unfortunately, renewable energies are dependent on environment conditions, too. One of the major problems that affect the output energy of the solar panel is the cloud shadowing problem. Photovoltaic solar and wind hybrid system is capable to reduce the effects of the cloud shadowing by harvesting two different energy resources. However, the availability of wind energy harvesting has shown its instability performance. In this work, the photovoltaic solar array of the laboratory-scale single axis solar tracking system to maximize the output energy of the solar panel is examined experimentally. The solar array is connected in series and parallel configurations, and is experimented under different partical-shadowed conditions. The experimentation is done to develop a solar array that has a minimum effect towards this type of occurances. Experimental results proved that the parallel configured solar panel has showed less influence by the cloud shadowing as compared to the single one.

This is the power point presentation of the Onalaja Oloruntimilehin Ogooluwa with Matric Number EES/17/18/0369 used for both the pre-defense and final defense of my undergraduate thesis "Photovoltaic Module Performance Estimation for Different Locations in Nigeria".
ABSTRACT
As renewable energy technologies gain prominence worldwide, photovoltaic (PV) systems are increasingly being deployed to harness solar energy. Accurate estimation of PV module performance is crucial for optimizing energy generation and ensuring efficient system design. This study focuses on estimating the performance of PV modules in three distinct locations in Nigeria, namely Lagos state, Enugu state, and Abuja.
The study utilizes a simplified methodology that combines meteorological data, PV system parameters, and performance modelling techniques. Meteorological data is the solar irradiance is collected from local weather stations in each location. The data is then processed to obtain representative solar resource profiles for each location.
To estimate the performance of PV modules, a software model called the Fundamental Photovoltaic Module Performance Analysis (FPVMPA) tool was used for this study.
The study evaluates the performance of commonly used PV module technologies for monocrystalline silicon using the Mitsubishi MJT250GB and the Sunpower X20 250. Factors such as module monthly yield, monthly capture losses, monthly module average power output, and monthly module generated power are assessed for different climatic conditions in Lagos state, Enugu state, and Abuja.
The findings of this research provide valuable insights into the expected performance of PV modules in the Nigerian context. The results can guide system designers, installers, and policymakers in selecting appropriate PV technologies and optimizing system configurations for each location. Furthermore, the study contributes to the growing body of knowledge on PV system performance estimation, specifically tailored to the Nigerian solar resource and climatic conditions.

Elevating Tactical DDD Patterns Through Object CalisthenicsDorra BARTAGUIZ
After immersing yourself in the blue book and its red counterpart, attending DDD-focused conferences, and applying tactical patterns, you're left with a crucial question: How do I ensure my design is effective? Tactical patterns within Domain-Driven Design (DDD) serve as guiding principles for creating clear and manageable domain models. However, achieving success with these patterns requires additional guidance. Interestingly, we've observed that a set of constraints initially designed for training purposes remarkably aligns with effective pattern implementation, offering a more ‘mechanical’ approach. Let's explore together how Object Calisthenics can elevate the design of your tactical DDD patterns, offering concrete help for those venturing into DDD for the first time!

Neuro-symbolic is not enough, we need neuro-*semantic*Frank van Harmelen
Neuro-symbolic (NeSy) AI is on the rise. However, simply machine learning on just any symbolic structure is not sufficient to really harvest the gains of NeSy. These will only be gained when the symbolic structures have an actual semantics. I give an operational definition of semantics as “predictable inference”.
All of this illustrated with link prediction over knowledge graphs, but the argument is general.
