Solar energy is most important form of renewable energy. It is cheap and easily available but it required a lot of area for production of solar power to install them in a particular space. This paper proposes a comparison of solar panel in matrix form and a solar power tree in a particular area. A solar power tree requires very less place to produce efficient energy. Solar Tree is made of metal structure , it has a number of solar panels which are used to give the shape of a tree and arranged in a tall tower. Spiralling phyllataxy is technique used to improve the efficiency of the plant as it prevent the lower panel shadowing. Solar photovoltaic modules are arranged in series form like fibonacci series in place of leaves in solar tree. By using this technique the amount of energy produced by solar tree is more than the energy produce by an array of solar cells. Solar trees are produces about 50% more electricity .The increasing energy demand, economy of land, the solar tree concept is very successful one and should be implemented to provide electricity. Solar tree is much better than the traditional solar PV system in area point of view and also more efficient.

Energy is the one of the basic requirements for sustained economic growth. To meet the growing requirement of energy, and to reduce the CO2 emission, many countries have chosen to meet its energy demand through renewable energy resources for sustainable development. Most popular renewable energy resources are solar and wind; due to the technological advancement in solar technology and its demand in the market made solar panels comparatively cheaper. One of the popular ways to extract solar power is installing solar rooftop. The main factor, which affects the performance of solar rooftop PV system, is power mismatch due to shading. In the literature, many reconfiguration methods have proposed based on electrical interconnections and physical location of the solar cell/modules. In this paper, physical-location based techniques are modified as electrical interconnection techniques and its performance is compared through experimentation at various shading patterns.

As we know, the need for electrical energy is increasing along with population growth and technological developments. This increase was also triggered by the growth rate of the energy demand of 6.86% per year. Most of the energy needs come from non-renewable energy, which has limitations and is not environmentally friendly. Despite being affected by Covid, this period is a momentum to start the direction of clean energy policies. The utilization of solar power can be started by utilizing a rooftop solar power system on the roof of a hotel or on the roof of other industrial buildings. As one of the research and development institutions in the housing and settlement infrastructure sector, it tries to provide alternative technology solutions through an innovative technology called PV-roof. The results of the research show that the designed roof off-grid has an average voltage and current on the first day of 13 Volts and a current of 1.8 A, and on the second day, 12.4 Volts and a current of 1.6 A, while on the third day, 12.8 Volts and current of 1.8 A. If the use of 1 battery bears a load of 450 Watts for 2.7 hours, then for users less than 5 hours, the solar charger controller capacity is 12.12 A.

A reconfiguration technique using a switched-capacitor (SC)-based voltage equalizer differential power processing (DPP) concept is proposed in this paper for photovoltaic (PV) systems at a cell/subpanel/panel-level. The proposed active diffusion charge redistribution (ADCR) architecture increases the energy yield during mismatch and adds a voltage boosting capability to the PV system under no mismatch by connected the available PV cells/panels in series. The technique performs a reconfiguration by measuring the PV cell/panel voltages and their irradiances. The power balancing is achieved by charge redistribution through SC under mismatch conditions, e.g., partial shading. Moreover, PV cells/panels remain in series under no mismatch. Overall, this paper analyzes, simulates, and evaluates the effectiveness of the proposed DPP architecture through a simulation-based model prepared in PSIM. Additionally, the effectiveness is also demonstrated by comparing it with existing conventional DPP and traditional bypass diode architecture.

Abstract Solar trackers make solar panels perpendicular to solar ray to enhance solar power reaping. The relative motion between Sun and Earth has two degrees of freedom. Sun travels from east to west during daytime and also moves north and south due to Earth’s tilt. However, Sun’s daily north-south move is much smaller than its east-west move. Sensor-based solar trackers make solar panels perpendicular to solar ray based on sensor information. Although the existing sensor-based solar trackers increase solar power reaping from solar panels significantly, they also consume considerable power by driving solar trackers. Sensorless solar trackers make solar panels perpendicular to solar ray based on calculated solar location. The performance of sensorless solar trackers is not affected by bad weather. This paper is on sensorless solar trackers. Single-axis solar trackers have one degree of freedom solar tracking motion. They can catch Sun’s daily east-west movement effectively. The Sun’s small north-south movement can be covered for single-axis solar trackers by monthly or seasonal adjustment of their orientations. This research is focused on single-axis sensorless solar trackers that are driven by linear actuators. The advantages of linear actuator driven solar trackers are their self-locking function and high load carrying capacity. Their challenges include limited solar panel motion range, potential interference between an oscillating solar panel and its fixed supporting ground link, and high motor power consumption for solar tracking. The research of this paper is motivated by surmounting the challenges facing sensorless single-axis linear actuator driven solar trackers. In this research, linear actuator driven solar trackers will be designed and analyzed. The models of the designed solar trackers will be developed. The kinematic and dynamic performances of the modeled solar trackers will be analyzed and simulated. The results of this research will provide some guidelines for developing linear actuator driven solar trackers.


Subject The outlook for the solar photovoltaic sector in China. Significance The EU's decision last month to remove tariffs on imported Chinese solar panels follows a US move to increase tariffs. It also comes at a time when international prices for panels are falling in response to a reduction of subsides for the deployment of solar photovoltaic (PV) capacity in China. Impacts Falling prices will stimulate further installation of solar PV capacity across the world, especially in sunny regions. Chinese manufacturers will further expand their capacity both at home and abroad. Non-Chinese PV manufacturers will find their profits squeezed even further unless they are protected by import controls. The rate of deployment of new solar PV capacity within China will decline, but still remain substantial.

Purpose The purpose of this study was to design a renovation plan for a university campus building (Department of Electrical and Computer Engineering) with the aim to achieve nearly zero energy performance, ensuring a low specific demand (lower than 44 kWh/m2) and a high level of on-site renewable generation (equivalent to more than 20 per cent of the energy demand). Design/methodology/approach The baseline demand was characterized based on energy audits, on smart metering data and on the existing building management system data, showing a recent reduction of the electricity demand owing to some implemented measures. The renovation plan was then designed with two main measures, the total replacement of the actual lighting by LEDs and the installation of a photovoltaic system (PV) with 78.8 kWp coupled with an energy storage system with 100 kWh of lithium-ion batteries. Findings The designed renovation achieved energy savings of 20 per cent, with 27.5 per cent of the consumed energy supplied by the PV system. This will ensure a reduction of the specific energy of the building to only 30 kWh/m2, with 42.4 per cent savings on the net-energy demand. Practical implications The designed renovation proves that it is possible to achieve nearly zero energy goals with cost-effective solutions, presenting the lighting renovation and the solar PV generation system a payback of 2.3 and 6.9 years, respectively. Originality/value This study innovated by defining ambitious goals to achieve nearly zero energy levels and presenting a design based on a comprehensive lighting retrofit and PV generation, whereas other studies are mostly based on envelope refurbishment and behaviour changes.

In the recent years, solar cooling technologies for buildings have garnered increased attention. This study aimed to evaluate the performance of current solar thermal and solar photovoltaic (PV) air-conditioning technologies. Hence, the annual heating/cooling load profile and energy consumption of a reference building in the climate of Aqaba, Jordan were simulated using the TRNSYS software. The solar thermal and solar PV air-conditioning systems were designed and simulated to compensate the cooling demands. It was found that the annual cooling energy accounted for 96.3 % of the total annual energy demand (heating plus cooling) of the reference building. The solar PV and solar thermal air-conditioning systems compensated for direct cooling by 35.8 % and 30.9 %, respectively, and the corresponding compensations of cooling energy by the storage system were 7.3 % and 11.9 %, respectively. Thus, through this comparative study, we found that the storage system significantly contributed in compensating the cooling demands of the solar thermal system; however, the compensation to direct cooling was lower relative to the solar PV system

This concept shows the design and control of a solar tree PV system for charging cell phones, supplying electricity for street lighting on open urban areas and charging of electric bike on the road side when the charge is decaying. Based on the above applications, a 7 feet height-tree was built. It has three section of branches, each branches contains 5 sub stem over which leaves made of acrylic with solar panels on the top (1.5 feet × 1feet) mounted. The energy storage capacity is 30 Amp. It has 2 USB ports to connect mobile devices and two 12V-300 W electrical outlets to connect those devices to the electricity. The solar tree was designed according to the environmental conditions of Gunupur, Odisha and for optimizing the output power a flow chart with programming developed. The result was compared with the C language programme. At the last, the PV system's availability to satisfy the energetic requirements was verified. Due to population growth and energy demands, the solar energy is the 2nd best source of non conventional energy which is cause pollution free in nature. By using the concept of the series and parallel connection of panel with the help of sub branch of the main stem the efficiency of the system can be improved. As compared to normal PV system in area point of view the Solar tree becomes more efficient. There is no systematic stimulation for usage of solar panels, purely relying on individual cases of installation on different types of objects. Solar tree may be very much helpful for creating awareness about solar resource. This concept elaborates the possibility of building a solar tree in GIET campus odisha, India, covering technical, social and economic aspects. Benefits and potential drawbacks are elaborated, while special emphasis is given to the specifics of its utilization due to the geographical position of odisha and corresponding number of sunny hours/days per year.
