Main photovoltaic installations in the world

Main photovoltaic installations in the world

The installation of large photovoltaic power plants in the world continues to increase both in number and installed power. As of today, there is already an installation in India that produces 1000MW. However, even larger photovoltaic solar power plants are still being built.

In this sense, the countries that lead the production of photovoltaic solar energy are China, the United States and India.

From the main photovoltaic solar installations in the world we highlight:

Kurnool Ultra Mega Solar Park. 1,000 MW. India

The Krnool Ultra Mega Solar photovoltaic park is located in India. Today it is already the largest photovoltaic plant in the world, surpassing the 850…

Solar collector

Solar collector

Solar collectors are the elements that capture solar radiation and convert it into thermal energy, into heat. It is a type of solar panel designed for use in solar thermal installations. It is also known as a solar collector.

The function of solar thermal energy is to take advantage of solar energy to obtain heat, to heat a fluid. Unlike photovoltaic solar energy whose function is to generate electricity.

As solar collectors, those with flat plates, those with vacuum tubes and absorber collectors without protection or isolation are known. The flat (or flat plate) collection systems with glass cover are the common ones in the production of sanitary hot water. The glass lets the…

Components of a solar thermal installation

Components of a solar thermal installation

The function of a solar thermal installation is to take advantage of solar energy to generate heat. The solar panels of these facilities capture the heat of the solar radiation that falls on them to heat a fluid. The different ways to take advantage of this hot fluid allows us to use this type of renewable energy in multiple applications.

A solar thermal installation consists of:

  • Solar collectors
  • Primary and secondary circuits
  • Heat exchanger
  • Accumulator, pumps
  • Glass of expansion
  • Pipelines
  • Main control panel.

Vacuum tube solar collector

Vacuum tube solar collector

A solar collector of vacuum tubes is a type of solar panel that takes advantage of solar thermal energy. This type of solar panel is formed by linear collectors housed in vacuum glass tubes.

The solar collector of vacuum tubes consists of a set of cylindrical tubes. The tubes are formed by a selective absorber, located on a reflector settlement and surrounded by a transparent glass cylinder.

Between the transparent outer tube and the inner absorber, the vacuum has been made. With this, conduction and convection losses from the absorbent surface are avoided and this fact allows reaching temperatures of more than 100ºC and making much more use of solar radiation.

Currently,…

Thermal solar collectors

Thermal solar collectors

A solar thermal collector is a component of a solar thermal installation. A solar collector is a type of solar panel responsible for capturing solar energy and transforming it into heat. It is also called the solar thermal collector.

The solar collector is the basic element of this renewable energy source.

From solar collectors there are many types. The solar collector used will depend on the use that is going to be given. For example, if we want to heat a pool to a temperature of 25-28ºC, in the spring, we need a simple sensor, since the ambient temperature will easily be of this order or even higher. On the other hand, if we want to heat a fluid to temperatures of 200ºC,…

Photollectric cell

Photollectric cell

In electronics, a photoelectric cell or a photovoltaic cell is an electrical / electronic device that converts the incident energy of solar radiation into electricity through the photovoltaic effect. Photovoltaic cells are the basic components of photovoltaic modules, which are solar panels capable of generating electrical energy from solar radiation. It is therefore the essential basic element for this type of renewable energy.

Compounds of a material that has a photoelectric effect absorb photons of light and emit electrons. When these free electrons are captured, the result is an electric current that can be used as electricity. A photovoltaic panel is composed of a group of photoelectric…

Photovoltaic Solar Energy

Photovoltaic Solar Energy

Solar photovoltaic energy consists in the direct transformation of solar radiation into electrical energy. This type of energy is often referred to directly as photovoltaic energy.

This transformation into electrical energy is achieved by taking advantage of the properties of semiconductor materials through photovoltaic cells. The base material for the manufacture of photovoltaic panels is usually silicon. When sunlight (photons) hits one of the faces of the solar cell, it generates an electric current. This generated electricity can be used as an energy source.

Manufacturing photovoltaic cells is a costly process, both economically and in time. The silica with which the photovoltaic…

Power inverter

Power 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.

A simple inverter consists of an oscillator that controls a transistor, which is used to interrupt…

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 network
  • Table of interconnection with the commercial electric network.

These…
