Solar panels are made up of a collection of semiconductor materials that absorb photons. The most common type of semiconductor material used is silicone, which is very plentiful on earth.
Photons from the sun strike the semi conductor material of the solar panel and are absorbed by electrons in the silicon semiconductor. For this to happen, [...]
Solar energy history began when the suns rays touched the earth for the first time, four billion years ago. In the early 1900s people used the suns energy to heat water and in the early 1950s research began into solar cells for generating electricity.
In the 1970s solar energy history was changed when President Carter began [...]
As the heading suggests this is a brief description of solar energy, and if you have ever asked how does solar energy work this is a good general introduction. This article will cover photovoltaic cells.
Solar power technology has advanced a great deal since its beginnings. A photovoltaic cell is a device that generates electricity by [...]
As most of us know, solar energy comes from the sun, which is located about 93 million miles from the earth.
What Can Solar Power Be Used For?
The suns energy can be used to heat our homes, heat water, generate electricity, power solar cars and operate communications equipment just to name a few of the endless [...]
Solar power is an area of interest to many people who are concerned about the environment we live in and the dwindling supply of resources available to us. When searching for alternatives to fossil fuels the topic that comes up most often is solar energy.
There are basically two categories that solar energy can be split [...]
Solar Energy Advantages
There is virtually an unlimited supply of solar energy for us to use and it is renewable. This means that our reliance on fossil fuels can be reduced in direct proportion by the amount of solar energy that we use.
Solar energy is an excellent alternative energy source because there is no pollution generated [...]
Solar powered houses are quickly becoming a viable option for many people today. The attraction of getting virtually free electricity to power houses is not only attractive because of high energy costs but also, and probably more importantly, because of our declining energy reserves.
Solar powered houses don’t seem to be as popular in North America [...]
