A New Configuration of Vertically Connecting Solar Cells: Solar Tree

Abstract

Solar energy is a renewable type, clean, and inexhaustible which is sufficiently available on the Algerian territory. The energy received daily on a horizontal surface of 1 m2 is in the order of 5 kWh over almost the whole Algerian territory; the duration of sunshine surpasses 2000 hours annually and can reach 3900 hours on the highlands and the Sahara. The importance of this work is based on exploiting solar energy to produce electricity. This study is based on the experimental exploitation of solar energy using solar tree’s prototype suggestion. This new model is focused to replace the leaf of a tree by the solar cell, starting by examining the solar field and physical phenomenon related with it; the description of cell photovoltaic comes after; and finally, the dimension of the solar system and the experimental studies are virtually released in the University of M’sila. In this work, a prototype of new artificial solar tree is proposed experimentally by using material available in the local market: 25 solar panels, metal support, electrical queues, regulator, and battery. The results highlight a power improvement in the case of the proposed new model (solar tree) compared to the traditional one provided (solar panel), for the specified time range between 8 am and 2:30 pm. On the other hand, the traditional model values improve if the time dimension is extended from 2:30 pm to 6:00 pm. This is due to the temperature of the region and the presence of interstellar spaces between the cells of the solar tree.

Árvore solar fotovoltaica: uma proposta técnica para implantação em ambientes públicos na cidade de Mossoró - RN

“…Ao comparar o sistema em questão, com o sistema solar fotovoltaico plano, fica evidente que as estruturas que compõem as árvores solares utilizam cerca de 1% da superfície e elevam a eficiência de 10% a 15%, além de fornecer um design único com alturas variáveis [10] [11]. Os sistemas de árvores solares, podem ser considerados singulares, pois são elaborados para auxiliar diversas pessoas em diferentes ambientes urbanos e também naturais, podendo gerar mais de 10% de energia elétrica quando comparado com um sistema fotovoltaico plano, ou seja, tradicional [12] [13].…”

Renewable energy adoption: Design, development, and assessment of solar tree for the mountainous region

“…The purpose of selecting DC voltage is to minimize the current losses 45 in cables and voltage drop. The standalone inverters of the solar system are connected to either a 240 or 360 V battery bank 46 to minimize loss load probability losses. The MPPT, charge controller, and inverters are installed in a suitably designed enclosure that protects the system from dust, wind, rain, and adulteration 47 .…”

Numerical Study on the Thermal Performance of Trombe Wall for Passive Solar Building in Semiarid Climate

“…The applications of renewable energies have fascinated the interest of many architects and engineers in recent days [1,2]. Several researches have shown the potential of using solar energy for satisfying energy demands of buildings [3][4][5] and industries [6] to alleviate the pollutant emission crisis [7,8].…”
