History of Solar Energy 1767‚ First Solar Collector In the year 1767 a Swiss scientist named Horace-Benedict de Saussure created the first solar collector – an insulated box covered with three layers of glass to absorb heat energy. Saussure’s box became widely known as the first solar oven‚ reaching temperatures of 230 degrees fahrenheit. 1839‚ Photovolataic Effect Defined In 1839 a major milestone in the evolution of solar energy happened with the defining of the photovoltaic effect.

October 2014 Mexico Mexico is such a beautiful country and there is so much more to Mexico and their culture then what people really think or know. It is were all my family is from. I am from a state called Durango. I have only been there a couple times but I know I am going to go back to visit sometime soon. Mexico is located right beneath the United States. It borders The Gulf of Mexico and the Caribbean Sea. It ’s geographic coordinates are 23 00 N‚ 102 00 W. Mexico is a total of 1‚964

A solar inverter‚ or PV inverter‚ converts the variable direct current (DC) output of a photovoltaic (PV) solar panel into a utility frequencyalternating current (AC) that can be fed into a commercial electrical grid or used by a local‚ off-grid electrical network. It is a critical component in a photovoltaic system‚ allowing the use of ordinary commercial appliances. Solar inverters have special functions adapted for use with photovoltaic arrays‚ including maximum power point tracking and anti-islanding protection

MEXICO Mexico is bordered by the United States to the north and Belize and Guatemala to the southeast. Mexico is about one-fifth the size of the United States. Baja California in the west is an 800-mile (1‚287-km) peninsula that forms the Gulf of California. In the east are the Gulf of Mexico and the Bay of Campeche‚ which is formed by Mexico’s other peninsula‚ the Yucatán. The center of Mexico is a great‚ high plateau‚ open to the north‚ with mountain chains on the east and west and with ocean-front

Solar Energy Introduction With the unlimited energy we receive from the sun‚ solar energy has the capabilities to meet the endless demand of energy and electricity both here in the United States and worldwide. Solar Energy is the one of a few energy sources that emits no carbon dioxide into the atmosphere at all. When comparing the cost and benefits of solar energy to other energy sources it is clear that solar energy is the most viable form of energy possible. With renewable energy becoming

Characteristics A solar panel is a collection of many small solar cells spread over a large area. These solar cells work together to provide sufficient energy to power a given item. (Northwestern University) Their creation is a very delicate process which is why many of their advancements did not come until last quarter of the 20th century. In this period‚ advancements in semiconductors and photovoltaic products allowed efficient and cost effective solar panels to be produced. (Solar Panel Info)

Solar seeker: In this project we design a solar seeker to follow a sun. solar seeker follow the sun and if the sensor attach on the sensor a sense a sun then solar seeker is stop automatically. Now after some time sun move from its position‚ then again seeker sensor sense the light and move the motor very slowly. If the sensor sense the signal then automatically stop the seeker . Movement of the seeker is restricted from left to right for limited area. To control the left and right limit
