The photoelectric effect is the formation and release of electrically charged particles produced in the matter when it is irradiated with light or other electromagnetic radiation. The term photoelectric effect designates several types of similar interactions. In the external photoelectric effect, electrons are liberated on the surface of a metallic conductor by absorbing energy from [...]
The PV or photovoltaic solar cells operate on the principle that electricity will flow between two dissimilar semiconductors to bring them into contact with each other and be exposed to light. Connecting a number of these cells to each other, appreciate that there is a useful and abundant flow of electrical current. A set of [...]
Because of its electrical properties, the solar photovoltaic modules or solar panels produce direct current instead of alternating current (AC). The direct current (DC) is characterized by the passage of electrons flowing in one direction (the type of power you get from a battery or an element of light). The alternating current is an electron [...]
Solar energy is increasingly popular with each jump in the value and power that few people know is the best investment in energy that can be made. Costs may be high at first but a solar panel has no moving parts and their components are silicon, glass, aluminum and some copper.
The average panel consists of [...]
A competition has been conducted between the solar companies Yingli Green Energy and SDIC Huajing Power to construct a 10mw plant to meet demand for solar energy at low costs for the Chinese, expect to produce the 0.1 kw USD, which is well below the current average.
These prices are possible thanks to large falls [...]
Cantillana Municipality of the city of Seville in Spain, has opened a solar plant that will provide electricity to more than 5,000 households, and its development was invested about 43 million dollars and 20 thousand people will benefit from this project.
The entire solar park is formed by 14 plants of 90 kW and a further [...]
Its goal is the purchase or sale of energy.
Google has created a subsidiary called Google Energy, and has asked federal authorities of the United States permission to enter the market for buying and selling energy. Google is a major consumer of electricity due to their servers and, for some time, is concerned about obtaining alternative [...]
It just has an average of 1.5 hours of solar energy to 100%. But that natural limitation is not a deterrent for Germany, which is now the number one country to harness this natural resource to generate electricity.
For the installed capacity and production of solar panels, plus the latest technology, the Germans are pioneers in [...]
Sandia National Laboratories and Stirling Energy Systems are joining forces to build and test six new solar systems for electricity generation that could feed more than 40 homes. In the future, hope to land areas equipped with 20,000 solar collectors.
Five new solar energy fields will be installed between now and next January at the National [...]
Earlier this week, the China Huaneng Group, started building a solar power plant that will be China’s largest, which will have the capacity to generate 166 megawatts in the province of Yunnan.
The project costs a total of one thousand three hundred million dollars, is planned to start operating in 2010. According to China Electricity Council, [...]
