Solar energy production involves taking advantage of sunlight to produce solar energy by means of solar panels. These panels are made up of solar cells, electrical devices based on silicon semiconductors, which generate electric current directly when sunlight falls on them. A collection of solar energy panels connected together is known as a “solar energy field”. When the sunlight falls on the solar energy field, we obtain a voltage and a continuous electric current, that is, a current with one positive and one negative pole
By means of an electrical device known as a converter or inverter, we convert the electric power obtained from the solar energy field to alternating current so that it can be distributed along the low tension lines that power our homes, factories and services. Connecting the output from the inverter to the electricity grid, we inject the power generated so it can be consumed by whoever requires it at that moment, thus becoming electrical energy producers and accordingly deriving valuable economic benefits. For that purpose, a counter is placed before the connection to the grid and the electricity company bills itself for the energy which we have introduced into its distribution network.
The output from solar energy installations is usually monitored using the inverter, which supports incorporation of transmission components which provide information about the status of the installation and the energy generated, and which raise alarms in the event of a fault, malfunctioning or unusually low output. These communications can be local in the form of a display or direct connection to computers, or remote by GPRS, SMS or the Internet.
Solar energy installations, whether solar fields or roof-based power plants, are made up of a small number of simple components: in addition to the solar panels, the plant comprises the supporting structure, the inverter for connection to the grid, the cabling and the protective elements.
Solar energy is modern, profitable and environmentally friendly and contributes to a change of direction in global energy practices. Currently solar energy generation is a kind of activity which is regulated and prestigious, operating within a stable legal framework.
