Most of the present day resources of energy are limited and irreplaceable. The next generation will face acute energy crisis if alternate resources of energy are not developed concurrently. Increasing cost and import of conventional resources have bad effect on the economy of a country, and the only cheaper solution is “unlimited power” from the sun. The use of solar energy is so far limited in household applications. In fact, if we harness only 0.0034 percent of the solar energy reaching the Earth’s surface, the energy need of the whole world will be met. In the present work, a substitute of 10-watt conventional night lamp has been proposed by a solar night lamp of the same light intensity through an experimental setup. The developed solar system is cheaper, portable, user friendly, and free from maintenance. The paper stresses on the need of replacement of conventional night lamp by solar night lamp in every home for reducing the energy crisis at present.

Abstract: Globally, renewable energy has grown remarkably. In the upcoming years, significant growth in the use of renewable energy is anticipated in India. With the majority of installations, solar energy led the renewable energy market, followed by wind energy. This demonstrates India's dedication to making the switch to a cleaner, more sustainable energy future. This research article discusses the design and fabrication of a prototype of a smart solar electricity generator flower i.e., the Smart Solar Flower (SSF), a unique and effective solar energy solution. It examines the features, advantages, and design of the SSF. The SSF, which was designed after flowers, autonomously tracks the sun to maximize energy harvesting. Photovoltaic panels, a solar tracking system, energy storage, a smart control unit, a self-cleaning mechanism, and sensors are some of its parts. The scalable and adaptive SSF may support energy-dependent systems, charge electric vehicles, power devices, and provide lighting. Intelligent sensor technology, machine learning, and Internet of Things connectivity enable autonomous adjustment based on the weather and energy consumption. Reduced reliance on fossil fuels, lower carbon emissions, and a sustainable future are all advantages for the environment. Installation expenses, energy savings, and money production are taken into account for economic viability. Efficiency, durability, and cost are explored along with challenges and prospects for the future. The SSF has significant promise for generating sustainable energy and revolutionizing the use of solar power to tackle global energy concerns.

The study focuses on utilization of the solar insulation in buildings by means of thermal storage materials. During months of April to October, a significant part of solar gain was noticed in outer walls as well as in roof of the structure. Light weight modern construction materials have low thermal inertia so it stores less energy. The study focuses on the utilization of Phase Change Materials (PCM) for harnessing solar thermal energy for heating buildings. Various researches that show the effect of implementing PCMs in different parts of buildings like in walls, roof, windows, doors, floor etc. has been shown in the paper. The PCMs are helpful especially for those buildings which are located in cold climatic condition. Effective solutions are still required for harnessing maximum possible solar energy for heating buildings by storing heat energy by means of thermal storage materials like PCMs in hot days and to liberate it in cold night.

Streszczenie:

The DESERTEC project, a European Union (EU) initiative to harness solar energy by means of Concentrated Solar Power (CSP) from Africa for use in Europe, shows the enormous potential that exists in alternative energy sources for the sub-region once there is political will. The Trans-Mediterranean Renewable Energy Corporation (TREC), a network of scientists and politicians who have taken it upon themselves to solve Europe’s energy problem using sun from Africa, conducted three studies which evaluated the potential of renewable energy resources in the Middle East and North Africa (MENA), the expected needs for water and power in EU-MENA between now and 2050 and issues relating to the construction of an electricity transmission grid connecting the EU and MENA (EU-MENA-Connection), with a formula to turn the North African desert sun into electricity and transport same to Europe. This paper harnesses the TREC fact-finding studies in order to estimate how much the same ideas can be applied in many other parts of the world, Nigeria in particular. Investigation reveals that this association exists with huge potentials for an energy-starved country like Nigeria in harnessing her abundant hot sun in the north, which could go a long way in meeting the energy needs in that part of the country and beyond. Other benefits include unlimited supplies of clean electricity, agricultural gains, and creation of new industries, new jobs and new sources of income.

Background: Doubly-Fed Induction Generator (DFIG) is a dual input conventional asynchronous device connected across both stator and rotor, which also functions as an electrical transducer consuming up-to 30 % of the generated power during the rotor injection. This is the major concern with respect to the DFIG in terms of effective power generation. Methods: The proposed work provides the solution for this undesirable power loss by connecting the DFIG with an array of solar Photovoltaic (PV) panel through a conventional direct current bus using a boost converter. This research setup can work on the basis of indirect vector control algorithms applied at the rotor and grid converter level in order to maintain the constant DC voltage under arbitrary conditions. Results: Even the variations in voltage and frequency will be controlled with this novel approach. A simulation model of the 300KW solar PV array and a 2MW DFIG system is developed using MATLAB/Simulink environment. Conclusion: Solar and wind energy sources incorporate Maximum Power Point Tracking (MPPT) through their control algorithms resulting in the add on 30-80 KW of solar power for rotor injection compared to the existing system in order to reduce the power rating of the converters and power consumption from the grid.

In this paper the technical and financial analysis was done for the extensive market survey relating to the solar energy harnessing in Karachi which is the biggest import, whole sale and retail market and follow as role model for most of other Pakistani markets. The severity of the electrical energy crises leads to the pressure on the individual user to find solutions for their long, load shedding hours. The marketing and advertisement exaggerated the Solar Photovoltaic panels as the best solutions which trigger the impulsive buying of solar modules and related accessories to produce the “free of cost” electrical energy. However, it was not proven as simple and free as it was marketed and advertised which leads to the tremendous loss of capital / investment and foreign exchange because of the major portion of solar energy related products are imported. In this work, several markets were survey and investigated i.e. Saddar, Bolten Shareshah, Qaidabade, Gulshan and Sohrab Goth where various brands of the solar panels were investigated by means of technical, financial and environmental based in order to optimize the policies and guideline for the investment, installation, operation and maintenance (OEM).

In photovoltaic (PV) systems, maximum power point (MPP) is tracked by matching the load impedance to the internal impedance of the PV array by adjusting the duty cycle of the associated DC-DC converter. Scientists are trying to improve the efficiency of these converters by improving the performance of the power stage, while limited attention is given to finding alternative methods. This article describes a novel supercapacitor (SC) assisted technique to enhance the efficiency of a PV system without modifying the power stage of the charge controller. The proposed system is an SC—battery hybrid PV system where an SC bank is coupled in series with a PV array to enhance the overall system efficiency. Developed prototype of the proposed system with SC assisted loss circumvention embedded with a DC microgrid application detailed in the article showed that the average efficiency of the PV system is increased by 8%. This article further describes the theoretical and experimental investigation of the impedance matching technique for the proposed PV system, explaining how to adapt typical impedance matching for maximum power transfer.

The current state of energy supply in Liberia is a combination of fossil fuel and hydroelectric power generation and the cost of generating, maintaining, and distributing energy is high. On the other hand, Liberia lies within a suitable zone for solar energy utilisation for photovoltaic applications, as its climate is relatively hot all year round. This paper investigates the use of the artificial neural network to model the reliability of solar radiation in a study area in Liberia, as a necessary prerequisite for alternative power generation. Seven variables (longitude, latitude, elevation, average temperature, precipitation, wind speed and relative humidity) were used as input data (causal variables) and one parameter/factor (solar radiation) was used as output (response variable) for 2000-2018. The obtained results showed that the employed model explains all the variabilities of the response data around the mean with an overall regression value of 0.93. It was found through visualised maps that the study area is in a suitable spot for the utilisation of solar energy potentials.

Solar energy is the most feasible source of renewable energy especially in sun rich regions like Africa. In particular, electrically epileptic country like Nigeria with current power output of only about 3.5GW of energy has a relatively long sunny period for about 90% of the year, making Nigeria very rich in solar power. Maximally harnessing solar energy into usable electricity however, is still a fundamental problem as the existing models can harness only about 70% of the available energy. To maximally harness solar energy, a solar panel must be perpendicular to the energy source for all 12hours of sunlight availability, and must be able to follow the sun’s movement all day long. Accordingly, this work considers the analysis, construction, and implementation of a single axis solar tracking dynamic system. Experimental result show that the proposed system outperforms the conventional static solar tracking system. Keywords: solar energy, single axis, harvesting-solar energy.

Being located in the Sun Belt, Pakistan is rich in sunlight and receives a high mean irradiation. This condition is ideal for harnessing Sun’s power for solar energy applications by using solar reflectors. In spite of possessing such a rich solar irradiation area, Pakistan is facing energy crisis because most of the energy resources are still unexploited. This paper discusses the energy crisis of Pakistan and provides the solution by putting efforts into solar energy technology, as well as devising innovative ways to incorporate solar reflectors into a solar panel and get more power generation out of it by a diminutive modification. Reflectors are used in the solar technology to concentrate the sunlight onto the solar panels. They employ glass as a base material with a silver coating and a protective layer over it. They elevate the energy input of solar panels as the whole solar spectrum is reflected on them. Materials with more reflective properties are needed to be used to increase the reflectivity and efficiency of solar reflectors. In Pakistan, no significant work is done till now towards the development of solar reflectors. If solar reflectors are used with the solar panels, then their efficiency as well as production from the solar panels will be maximized.

Climate is rapidly changing with disruptive impacts. Without decisive action, energy-related greenhouse gas (GHG) emissions would lead to climate degradation. All types of energy efficiency technologies will require widespread deployment, as global warming is likely to reach 1.5°C between 2030 and 2052, if it continues to increase at the current rate. Photovoltaic (PV) energy is one of the most promising emerging technologies in mitigating the impact of climate change. PV is the name of a method of converting solar energy into direct current electricity. Therefore, the objectives of this article are to study the initiatives taken by energy development agencies in India for promoting renewable sources of energy, to study the use of solar power as a renewable source of energy through PV system and to analyse the solar PV rooftop system in Chandigarh as a case study. The article is an empirical study based on primary data. For the purpose of collecting the primary data, a structured questionnaire was prepared for citizens and an interview schedule for officials. The results of the study show that the majority of the citizens were satisfied with the solar photovoltaic (SPV) installations in Chandigarh, while a very few of them were dissatisfied and their dissatisfaction revolved around getting clearances from different departments.

With the fast depletion of the conventional energy resources and the amount of pollution it is creating, the entire world is looking for an alternative non-conventional and a renewable energy to lessen the dependency on the conventional energy resources. In this scenario, utilizing solar energy which is abundant in nature is gaining high attention. One way of utilizing solar energy is by using solar photovoltaic cells which convert light energy into electrical energy, but they are too costly and less efficient. Many techniques are being developed to reduce the cost and improve the efficiency in harnessing solar energy. Sun tracking technique is one of the methods to increase the efficiency of solar cells. The present work is focused on providing a microcontroller based automatic two-axis sun tracker using Photodiodes as sensors to track sun. The system is assisted with a manual control through LabVIEW (Graphical User friendly Interface) to aid during bad weather conditions.

The continuously increasing use of photovoltaic cells requires various efforts to maximize the harnessing of solar energy. This paper presents the research results of fuzzy-logic method implementation to maximize the absorption of solar energy. It is based on the optimization of solar panels position according to the sun direction. The Takagi-Sugeno method is chosen in the fuzzification stage. The control algorithm is implemented on a microcontroller ATMega-128 using BASCOM-AVR program. DC motor is used to actuate the solar panels. The results show an increase of 0.48V in the output of solar cells sensor using the fuzzy logic computation-based tracking system. The resulted tracking system proves to consume less power because the tracking process is halted while moving the DC motor continuously.

Energy demand taking a bigger leap day by day, Renewable energy gets the most leading importance in catering the purpose. Solar being the abundantly available renewable energy resource solar panels are key components in harnessing solar energy. Solar energy is the most dependable and cheap energy in renewable sector. But harnessing solar energy with partial shading makes it difficult for simple tracking algorithm because of multiple power peak points. Settling time of DC link voltage during the dynamics in the load and the irradiation also plays a major role in power delivered to the grid . Highly dynamic situation aware processors have been in the verge for many applications where large amount of online processing is a need like the smart grid, which needs a faster online reacting time. This paper deals with such an online reacting Maximum Power Point Optimization (MPPO) on a PV system with Partial shaded condition (PSC). The MPPO uses the recent non-parametric optimization techniques like Particle Swarm Optimization (PSO) for maximizing the power delivered from the solar panel. This optimization is achieved by populating the duty cycle and Kp and Ki parameters of PI controller given to the DC-DC converter connected to the PV arrays for the stable supply to the grid. While applying the maximization algorithm for the solar power output from the PV arrays the PSC conditions are considered in order to make the control technique more robust. This paper deals with minimization of DC link voltage settling time and maximization of power in multi-objective,. MATLAB based simulation is carried and the comparative inference is produced in this paper. The simulation is developed for the 2.5kW PV array with the proposed method. The simulation carried out had performed better with the proposed method than the single objective method.Satisfactory results were observed both in the simulation of the proposed algorithm.

Solar-driven interfacial evaporation system has attracted intensive attention owing to its great potential in harnessing renewable solar energy to purify water. To further enhance the solar-driven interfacial evaporation system performance, solar absorber structure with high light-thermal energy conversion efficiency is especially critical. In this work, polyvinyl pyrrolidone/poly(vinylidene fluoride co hexa fluoropropylene)/CuO-nanorods (PVP/PVDF-HFP/CuO-nanorods) membrane was prepared sequentially by electrospinning, heating and hydrothermal processes. The flexible electrospun membrane was used as the photothermal layer in the solar-driven interfacial evaporation system. The evenly distributed CuO nanorods function as solar energy absorbers. The polystyrene foam was used as an insulating layer, and filter paper was inserted in the middle of the polystyrene foam to transport water to the photothermal layer. The designed evaporator was used for the solar evaporation using pure water. As a result, the evaporation rate was 1.11 kg/m2h and the light-thermal energy conversion rate was 75.36%. The outcome of this work provides the potential of solar-driven interfacial evaporation system for water desalination and wastewater purification.

Abstract The seasonal nature of solar panels and windmills has been a major challenge towards realizing sustainable energy. Over the years, several attempts have been made to perfect a device capable of harnessing the energy of wind and rain, titled as triboelectric and piezoelectric nano generators. Although such technologies yield promising results, a superior energy device can be achieved by addition of solar cells to wind and rain energy harvesting devices. Hybrid Nano generators are expected to be the future of commercially sustainable energy generation which are used to simultaneously harvest wind, rain, and solar energy. Though a substantial amount of work has been done with regard to such energy harvesting modules, studies that test their environmental capabilities are limited. In this study, a hybridized power panel comprising of dual-mode triboelectric nano generator and a solar cell have been tested under majorly solar, majorly windy, majorly rainy, and normal tropical conditions. Average temperature attained by the panel in such conditions have been studied through a transient thermal analysis done using Ansys Fluent. The results obtained are used to calculate thermal strain in the panel for different cases. The proposed model is an innovative way to make use of energy.

Solar energy is the most important green energy source that may be used to address the problems caused by conventional energy sources. The research in this paper aims to evaluate the solar energy potential of M'Sila, an Algerian internal region, and to determine which technology, among those currently available on the market, is adequate for harnessing that potential for electricity production (PV and CSP). This assessment was based on data (daily temperature and daily solar irradiation) collected at M'Sila weather station for one year and from the NASA site for 34 years from 1984 to 2017. These data were treated with excel 2016 software to determine the total horizontal, diffuse and direct normal solar irradiation. During the study period, the total solar irradiation falling on a horizontal surface in M'Sila (GHI) was estimated to be 1.79 MWh/m2/year. The diffuse solar irradiation incident on a horizontal surface (DHI) and direct normal irradiation, respectively, were estimated to be 594.88 kWh/m2/year, 2117.93 kWh/m2/year. M'Sila is a favourable land for the installation of concentrating solar power plants and photovoltaic panels due to its significant potential energy. The parabolic trough system is recommended. While polycrystalline PV modules should be promoted and installed in M'Sila.

This study aimed to explore solar energy potential on a small landscape (campus of the College of Natural Resources) using topography of fine spatial resolution that can detect number of rooftops feasible for harnessing solar energy. Digital elevation model was derived by extracting elevation values from the Google Earth Pro which was then used as input for solar radiation calculation. The total radiation that the campus received was 2,100 kWh over 259 days and the result was validated using power access viewer and global solar atlas databases. The monthly average radiation indicated that October, November, December and January are the radiation peaking months at the college campus. Twenty two rooftops were identified to receive more than or equal to 3.08 kWh/m2/day, while the remaining rooftops receiving less than or equal to 3.08 kWh/m2/day. The college has potential of supplementing power shortage during lean hydro season using the rooftop solar panels.

The current situation of fast depleting non-renewable resources and excessive damage done to mother earth due to severe mechanization and industrialization has resulted in alarming rate of pollutions. The one-word answer for it is that we should start harnessing renewable resources of energy. Tapping sun’s energy is a wonderful and apt answer to the current situation of energy requirement. World over this technology is worked upon to make use of sun’s energy easy to be converted into usable energy form i.e. electricity. The research work being carried on in varied fields however to mention one such aspect of solar panels is irradiance -receiving and capturing powers. Along with the irradiance, the area of a panel which is exposed to sun, the daytime and location are some of the factors affecting the amount of power generated using solar power as generating source. From research point of view, to analyze the effect of variation of these parameters, it is difficult to get the analysis data using solar panels and hence now a day’s emulator is preferred and used for research purposes. This paper focuses on the basics of emulator, its structure, functioning, effect of various parameter variations on the analysis of the generated power and other related benefits using emulator. The paper also presents the effect of partial shading on the maximum power generated and the efficiency hence obtained. The performance analysis is done on an Experimental set up fabricated in Research lab.
