What is Photovoltaics?

Solar photovoltaic and photovoltaic cell phenomenon. Put simply, photovoltaics is a set of elements made it possible to convert solar energy into electrical energy.

Photovoltaic phenomenon was discovered in the 19th century, but the first photovoltaic article was made up to ca. 40 years after the discovery of the photovoltaic phenomenon. Then the first link was only 1% efficiency over today's 16%.

During the photovoltaic phenomenon is the impact of sunlight on the surface of the photovoltaic cell. There is direct electrical current, which can be used such as recharging batteries. Using the inverter can convert DC electricity to alternating current, which can consume or supply mains.

Maximum power, which is able to achieve a particular solar system is called unit Wp (watt peak). It is true that 1kWp is equal to 1000 Wp.

Photovoltaic power plant.

Photovoltaic power plant is a set of smaller or larger number of solar panels, inverters and inverters, support and protection elements. The principle of the photovoltaic system is producing electricity from sunlight using silicon cells, which changes this energy into electrical energy. Energy so produced is then distributed to the public network and sold at a pre-set feed-in tariffs.

For operator photovoltaic system used to distribute electricity to the public network, it is certainly important, how he will evaluate the investment. In support of the Energy Act, alleging that the return on investment of FV have been near 8 to 10 years. This is a very sound way to generate the environment (elimination of carbon dioxide caused by burning fossil fuels). Taking into account that the sun is an inexhaustible resource and that the system is virtually maintenance-free long life, based on our ideal prospects for the future.

Solar power can stand on the roof of his family house, cottages, factory building or perhaps in the field. There are 3 basic forms of solar power plant by way of electrical power supply to the electricity grid.

Island system - it is form without connection to electric grid, thus the direct consumption of energy produced and used mainly in places where there is no option to connect to the electrical connection.

Connection to a separate network connection - As the name suggests, it is setting up a separate connection to solar power distribution network, sell power generated in the network without the possibility of their own consumption. A separate connection is usually necessary to set up for larger plants that are built solely for profit, and where there is no consumption of energy produced at its production. Profitability standing power provides a guaranteed purchase price.

Connecting to a separate power connection, most of standing on the green meadow. The reason is simple - most of the grassland and other vacant land is not connected to a public distribution network, as you yourselves know.

Connecting to the network using a so-called green bonus. - This method is suitable for those who produced electricity can simultaneously consume. 100% of your electricity generated by photovoltaic power plant selling network, but also you can consume for free. Distribution companies are obliged by law to pay each kWh produced. Thus the measurement on two electricity meters for a photovoltaic power plant and the second meter connections, which can be measured in two directions from the network and the network

Where to build a Photovoltaic power plant.

The simplest solution is to install the roof. This eliminates concern with building permission and use the area, which, outside the protection against climatic influences, is not efficiently used. Selected roof must meet certain parameters - the slope, orientation and appropriate size. The combination of these indicators have a significant impact on the efficiency of power plants.

CR its location can offer a ray such as the southern destinations but its location provides a good basis for a rapid return on investment. The ideal location of solar panels should be in a southerly direction with a tolerance of 10-15 ° to the west. Slope of solar panels should be 30 ° -35 °. Of course, nothing to prevent sunlight.

Pages are gradually supplemented by the solar panels that should be available in our company.
