maximum power point tracking (MPPT) algorithms in a photovoltaic simulation system. The Matlab/Simulink is used in this paper to establish a model of photovoltaic system with MPPT function. This system is developed by combining the models of established solar module and DC-DC buck-boost converter with the algorithms of perturbation and observation (P&O)‚ incremental conductance (INC) and hill climbing (HC)‚ respectively. The system is simulated under different climate conditions and MPPT algorithms. According

energy needs for an entire year. Solar energy is the technology used to harness the sun’s energy and make it useable. Solar Energy is the energy from the Sun. The Sun is a big ball of heat and light resulting from nuclear fusion at its core. The nuclear reaction releases energy that travels outward to the surface of the Sun. Along the way to the surface the energy transforms so that by the time it is released it is primarily light energy. The two major types of solar energy that make it to Earth

Cinddy Solar energy Today‚ people make full use of solar energy and it benefits them a lot‚ especially in Spain and China. Due to their favorable conditions‚ solar energy has good practicality. It is much more convenient to use solar energy as people’s main energy resources than other renewable energy. The government gives financial support of solar energy which largely stimulates the growth of renewable energy. In addition‚ solar energy has a huge amount of influence on people’s life such

According to the National Geographic Magazine‚ the use of solar polar or photovoltaic cells has surged at about 20 percent a year over the past 15 years. This is thanks to rapidly falling prices and gains in efficiency. Countries such as Japan‚ Germany and the United States are major markets for solar cells. With tax incentives‚ solar electricity can often pay for itself in five to ten years. (National Geographic) With this fact in mind‚ it is no wonder that the city of Massachusetts politicians

Solar eclipse From Wikipedia‚ the free encyclopedia Jump to: navigation‚ search Not to be confused with Lunar eclipse. Photo of 1999 total eclipse As seen from the Earth‚ a solar eclipse occurs when the Moon passes between the Sun and Earth‚ and the Moon fully or partially blocks ("occults") the Sun. This can happen only at new moon‚ when the Sun and the Moon are in conjunction as seen from Earth in an alignment referred to as syzygy. In a total eclipse‚ the disk of the Sun is fully obscured

The marketing environment consists of the actors and forces outside marketing that effect marketing management’s ability to develop and maintain successful transactions with its target customers. "(Kotler 2009) Marketplace becomes more competitive after being rapidly changed by economics‚ technology and globalization." Without building customer relationship‚ only driven by product and technology is no longer enough for company. "(Kotler 2009) Thus‚ marketing mix has to be adapted for an organization

“Solar Treated Purification” Intorduction: A. Background of the study: In our world today‚ purified water is the one that most of the people drink everyday especially those who live in cities. Water purification is the process of removing undesirable chemicals‚ biological contaminants‚ suspended solids and gases from contaminated water. The goal is to produce water fit for a specific purpose. Most water is purified for human consumption (drinking water)‚ but water purification may also be designed

from the Earth‚ a solar eclipse occurs when the Moon passes between the Sun and Earth‚ and the Moon fully or partially blocks the Sun. This can happen only at new moon‚ when the Sun and the Moon are in conjunction as seen from Earth. In a total eclipse‚ the disk of the Sun is fully obscured by the Moon. In partial and annular eclipses only part of the Sun is obscured.If the Moon were in a circular orbit close enough to the Earth and in the same orbital plane‚ there would be total solar eclipses every
