Solar PV farms use the power of the sun to convert UV light into usable electricity. The panels generate direct current. This is transformed via inverters into alternating current which is suitable for use in every home and business in the country. This type of technology was originally designed by NASA and can now be seen throughout Europe as an effective way of delivering clean renewable electricity to communities.
Solar farms are a great way of producing clean renewable energy and can be easily screened using existing or new hedge rows. By using the existing grid infrastructure solar farms can help reduce the need for major grid reinforcements by ensuring each and every community has its own supply of electricity.
SOLAR IN UK & IRELAND
The UK and Ireland have the capacity to deliver viable solar energy as PV panels generate electricity during daylight hours. The UK has so far deployed 9+GW of solar PV developments and it is envisaged that commerical scale projects in Ireland will be deployed from 2017. In terms of comparison to mainland Europe, the solar resource in Ireland is close to 70% of the level in Spain.
MAIN ELEMENTS IN A PV FARM
A solar panel (or module) is a series of interconnecting silicon cells joined together to form a circuit. In large numbers the amount of power produced by these interconnected cells can be increased and used as an electricity production system.
An inverter is an electronic device or circuitry that changes direct current (DC) to alternating current (AC). The inverter does not produce any power; the power is provided by the DC source (PV modules).
A transformer is an electrical device that transfers electrical energy between two or more circuits through electromagnetic induction. Transformers are used to increase or decrease the alternating voltage in electric power applications. In the case of PV farms the transformers increase the voltage of the power produced by the modules so that it can be exported to the grid.
