Solar PV Systems: Three Steps to Success
For the true success of solar energy, people all over the world need to take three basic steps. The last step - the fourth step - is going out and buying a solar energy system. But before this, please do the following:
Step 1: Conserving energy means:
Step 2: Improving your energy efficiency means:
Step 3: Deciding on a solar energy system that fits your needs includes:
Solar4Scholars: Solar Electricity
What is solar electricity?
In solar photovoltaic energy, sunlight causes electrons to move and become electricity.
This technology was first developed for space travel in the 1950's. It was originally used to power satellites, a very practical use for solar, as there are no clouds in space.
Solar electricity is produced by solar cells that range in size from one square inch up to ten square inches. A single solar cell produces a small amount of electricity. Solar panels are made up of cells grouped together to produce a worthwhile amount of electricity.
Here on earth, we use solar electricity for a number of purposes. Solar panels (also called modules) are used to power homes. In some cases, people use small portable solar energy systems to power equipment for RVs, camping and other activities. You can find small solar cells on solar calculators and solar lights. Solar has many other practical uses, too.
How does a solar cell work?
Solar cells are most often made of crystals of silicon. Large silicon crystals are cut into thin wafers and fused together. These two separate wafers are composed of two different materials with different properties. When sunlight strikes the solar cell, photons dislodge electrons that travel from one layer to the other. This flow of electrons is, by definition, electricity.
How do people use solar energy?
When you have enough solar cells linked together in a solar panel, and these panels are also linked in an array, yo...
