Solar Panels Solar Panels‚ also known as Solar Cells‚ convert solar energy into electrical energy. When sunlight hits the solar panel it knocks electrons loose from their atoms and then they move through the built in circuit‚ thus creating a current of energy. This energy can be stored in batteries for later use or it can be used right away. Antoine César Becquerel‚ a French scientist‚ and his son‚ Alexandre-Edmond Becquerel‚ were the first to notice photovoltaic power in 1839. They discovered

INTRODUCTION When thinking of starting a contracting business for solar panels‚ many economic issues and concerns play a factor in the decision making process. Having a concern for the environment and knowing that solar panels have a cost saving for both households and business seems to be reason enough to start a business. However‚ before making such a financial investment you should first take a look solar panels in the economy in terms of (i) GDP growth rate‚ (ii) interest rates‚ (iii) level

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

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

The article “Why I am Not an Environmentalist” criticizes environmentalism through the lens of an economist. The author‚ Steven Landsburg‚ compares environmentalism to religion. This issue came up for him when he first took action against preschool teachers at his daughter’s school. They were talking about Christianity while his daughter and a few others‚ were not of Christian faith. He confronted them and the problem was solved. Later‚ his daughter came home talking about environmentalism and recycling

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.

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
