Solar Energy‚ usually refers to the sun radiation Energy‚ in the modern society‚ generally used for power generation. Since the earth created creatures‚ those creatures depended on the heat and light of the sun‚ band also human beings knew to dry the objects in the sunlight‚ by which they kept food‚ such as salt-making and drying of salted fish‚ etc. But with the reduction of fossil fuel resources‚ then people are disposed to develop solar energy further. The methods of solar energy using include

Chemistry Department Speaker on Solar Cells — Outside event October 24‚ 2017 Today I attended a talk curated by the Ithaca College Chemistry Department by Kathleen Sampson‚ a Ph.D. Candidate at the University of Toronto. Sampson presented about the intersections of chemistry and engineering in regards to innovating new materials to produce solar energy. Sampson discussed organic solar cells‚ a type of solar energy technology that converts sunlight into electricity using “Earth-abundant‚ carbon-based

Case Study: Does the Sun’s Angle Affect the Output Of a Solar Cell? Abstract During the experiment to determine Solar Cell Energy‚ one unit of flexible solar cells was exposed to solar radiation at different angles in one axis of rotation. The cells were attached to a adjustable plane with a protractor that acted like a “see-saw” to adjust the angle of the solar cells to the Sun. Around the plane‚ a column of cardboard was constructed with black fabric covering the inside

Design of DC Motor Driver for Solar Tracking Applications Abstract - Solar trackers rely on a direct-current (DC) motor driver circuit to control the movement of the solar panel. However‚ conventional DC motor drivers used in solar tracking system do not provide any options for speed and torque control. Hence‚ the fixed speed of the DC motor leads to either too fast or too slow tracking movement. Usually‚ the output torque is set to the maximum. If the load (solar panels’ weight) is small‚ the

The Solar System‚ where the planet Earth belongs‚ is formed by: a start known as the sun‚ four inner planets‚ Mercury‚ Venus‚ Earth and Mars‚ and five outer planets‚ Jupiter‚ Saturn‚ Uranus‚ Neptune and Pluto‚ over 60 satellites or moons‚ more than 5‚000 asteroids‚ numerous comets‚ and smaller interplanetary dust and debris (“Astronomy n.pag). The way that all this elements of the Solar System interact and move around the Sun seems to be perfectly synchronized but‚ how did it began? What was it

Planets and moons in our solar system share many similar properties‚ but there are also many ways they are different. Some of the main differences come with the different geologic activity‚ composition‚ interior structure‚ magnetic field‚ and atmosphere that distinguish some planets and moons from others. The first way to separate the planets as far as their surfaces is breaking them into their two categories. The Jovian planets (Jupiter‚ Saturn‚ Uranus‚ Neptune) are primarily composed of gas and

Solar Power For millions of years the sun has wrapped the world in it ’s warmth and light‚ providing the necessities for life. Even now we are still finding many uses for the massive amount of energy the sun produces. Light travels to the earth in about eight seconds and is filled with little packets of energy called photons‚ which make utalizing this solar power possible. There are three main ways to collect solar power. The first two are called passive system and active system. These use the

Inside the Solar System: Comet C/2011 N3 PSC 103 - Astronomy Summer 2012 According to an article written in early January Scientific American (Matson‚ 2012)‚ on July 6th‚ for the first time ever‚ a sun-watching spacecraft has traced a comet’s route directly into the sun. The magazine boasts this as the “Solar Swan Song” (Matson‚ 2012) and compares this comet’s demise to dramatic exits in the movie Dr. Strangelove. Discovered by the Solar and Heliospheric Observatory‚ otherwise known as SOHO
