Learn Solar Panel Installation Practices With A Pv Training Course

By:


Photovoltaics, or PV, is the technology which produces direct current (DC) electricity from light, usually sunlight. In recent times there has been a growth of interest in renewable energy sources, and this has led to growth in the utilization of PV arrays and solar cells. Improved manufacturing techniques, and new solar cell designs have helped drive down cost. There are also financial incentives in some countries for the use of renewable energy. One way to gain useful knowledge and skills in this expanding sector is to take a solar PV training course.

When a solar cell is exposed to sunlight a small voltage is produced. This is called the photovoltaic effect. As the voltage (per cell) is only about half a Volt, it is normal to connect many cells in series.

Generally the cells are packed behind a glass sheet to protect them from the environment, and an array of many modules is arranged to provide sufficient power for any application. As the sun does not shine at night, and as the weather is sometimes cloudy, some means must be provided to store energy in an installation. Usually this will be by means of lead-acid batteries.

Some PV installations are completely self-contained. This can be beneficial in locations where connection to the grid would be expensive or impractical, such as lighthouses, temporary traffic lights, water pumps, parking meters and emergency telephones.

Other PV systems are connected to the grid. This gives the flexibility to draw electricity from the grid when the sun is not shining (ie at night), and to feed electricity back into the grid during sunny days. Tariff structures in a number of countries can make this a viable option for the owners of buildings, including homes.

For example the United Kingdom's Feed-In tariff has been designed to support renewable (green) energy sources. For each unit (1 kWh) fed back into the grid, the owner of the solar cell installation will receive a fee (or a discount on his electric bill). To convert the solar power (DC) to the AC needed by the mains grid requires an inverter unit as part of the installation.

Solar PV training courses, in various locations, are available to those interested in pursuing career or business opportunities in this expanding sector of the electricity building. Many aspects of the technology are covered in different courses, including installation practices, and manufacturing technologies.
