solar water heating collectors
You may have heard that it is possible to make your own electricity and thereby reduce your electricity bills. Can this be done by placing solar panels on the roof of your house? How does this work?
This article will answer questions related to the use of panels also known as photovoltaic cells, and try to dispel some of the confusion that so many people experience about the subject.
Solar panels and solar thermal collectors are two words often used in reference to collecting and using solar energy, but the two systems work in a very different way. These are in fact different technologies.
Thermal collectors do not produce electricity,but transform collected solar energy into usable heat energy that can be used to warm or cool the house and/or water for the house. Heat is the process of energy transfer from one body to another due to a difference in temperature, it is also called thermal energy. Solar panels collect solar energy in the form of electricity. Effectively thermal collectors use the sun to heat water or another fluid such as oil or antifreeze and circulates that heat.
Electricity can be produced from solar energy collected in photovoltaic cells, not in thermal collectors. A photovoltaic cell is a specialized semiconductor diode that converts visible light into direct current.
Photovoltaic cells are made of crystalline silicon or gallium arsenide. Gallium arsenide is still a very expensive material that is grown especially for use in photovoltaic cells. Its use is therefore still limited, most people giving preference to the less expensive silicon crystals. But we must note that silicon crystals have a lower sunlight to electricity conversion efficiency.
Photovoltaic cells also known are packaged and connected to each other electronically. These cells usually require protection from the environment. For this reason these cells are disposed in several layers to form a module, sometimes called an array. Several modules wired and fastened together form a panel, which can then be installed as a unit, oftentimes in a frame with a glass covering.
We consider that a 10 to 30 square yard area covered with panels as described above would produce the electricity needed by a single household.
Once installed solar panels will convert solar energy into direct current that will need to be converted to alternating current, the kind we use for our appliances. This last conversion is done by means of inverters.
A typical unit will thus include the photovoltaic modules, an inverter, batteries and interconnection wiring.
Electricity produced this way can then be used directly in the building housing the panels or it can be diverted to an electric network also called a grid.
