Alternating Current

Alternating Current

Alternating current (AC) is a type of electric current that is characterized by changing over time, either in intensity or direction, at regular intervals.

The voltage varies between the maximum and minimum values cyclically, the value of the voltage is positive half the time (half positive cycle or half positive period) and negative the other half. This means that half the time the current flows in one direction, the other half in the other direction. The most common form of undulation follows a sine-type trigonometric function, since it is the most efficient and practical way to produce…

Direct Current

Direct Current

The direct current is a type of electric current very important in solar energy where the direction of flow of electric charges (electrons) does not vary. In many devices the symbol to indicate direct current is DC (direct current), or using the symbol of a continuous line (-) flanked by three shorter lines (---), for the alternating current that is used instead of AC (alternating current) or the symbol (~).

The flow of charges occurs through a conductor, such as a metallic thread. The flow could also be established through a semiconductor, an insulator or even vacuum as in a cathode…

Photovoltaic Power Plant

Photovoltaic Power Plant

A photovoltaic power plant is a set of facilities designed to supply electricity to the grid through the use of large-scale photovoltaic systems. The function of the photovoltaic power station is to capture and transform solar radiation into electricity.

A photovoltaic power plant is a power plant consisting basically of photovoltaic modules and an inverter. The photovoltaic panels are in charge of transforming the solar radiation, into electrical energy of direct current. The inverter is the electronic equipment whose function is to convert the DC power produced by the photovoltaic…

Inverter

Inverter

An inverter is an electronic device. The function of the inverter is to change a DC input voltage to a symmetrical AC output voltage, with the magnitude and frequency desired by the user. The inverters use in a great variety of applications, from small power supplies for computers, to industrial applications to control high power. The inverters are also used to convert the direct current generated by photovoltaic solar panels, accumulators or batteries, etc., into alternating current and thus be able to be injected into the electrical network or used in isolated electrical installations.

Electricity

We have two definitions of electricity depending on whether ns refer to physical phenomena on a macroscopic scale or on a microscopic scale.

With the term electricity we refer generically to all physical phenomena in a macroscopic scale that involves one of the fundamental interactions, the electromagnetic force, with particular reference to electrostatics. At the microscopic level, these phenomena are due to the interaction between charged particles on a molecular scale: the protons in the nucleus of atoms or ionized molecules and the electrons. The typical macroscopic effects of such…

Components Of Photovoltaic Installations Connected To The Network

Components Of Photovoltaic Installations Connected To The Network

A photovoltaic solar installation connected to the network has only three basic elements:

  • A group of photovoltaic solar panels. These solar panels are usually located on the roof of a building or integrated into any structural element of the same building. The photovoltaic panels can also be arranged directly on any land near the electricity grid.
  • Ondulator or electronic inverter-converter. This device transforms the energy in the form of direct current provided by the solar panels, in alternating current of the same type and value as the one transported by the electric…

Components Of Autonomous Photovoltaic Installations

Components Of Autonomous Photovoltaic Installations

Autonomous photovoltaic installations are those installations that are isolated from the electricity grid. All electrical energy generated by solar panels is consumed directly.

This type of photovoltaic installation is designed for the cases in which the cost of maintenance and installation of the power lines is not profitable. For example, this would be the case of mountain refuge.

The main element of autonomous photovoltaic installations is the photovoltaic panel. The photovoltaic panel is responsible for transforming solar radiation into electrical energy in the form of direct…
