Watt - Power unit

The watt (symbol: W) is the power unit of the International System, it is the amount of energy in joules that is converted, used or dissipated in one second. It is a derived unit that takes its name from the engineer, inventor and constructor of Scottish instruments James Watt, for his contribution to the development of the steam engine, which was one of the triggers of the beginning of the Industrial Revolution.

The watt was adopted by the Second Congress of the British Association for the Advancement of Science in 1889, which meant its international recognition as a power unit, incorporating…

Hydroelectric power

Hydroelectric power

Hydropower is the electric power produced in a hydroelectric power station from a current, vertical or horizontal, of a river. In other words, it is electricity (electrical energy) obtained from hydraulic energy (mechanical energy of water in movement of rivers, lakes and marshes).

The difference between hydroelectric and hydraulic energy is that hydraulic energy can be used to generate electrical energy but also to obtain energy of another type, for example, mechanical energy. While hydropower refers only to the use of hydropower to obtain electric power or electricity.

The technical…

Hydraulic energy

Hydraulic energy

Hydropower is a source of renewable and alternative energy. This renewable energy exploits the transformation of gravitational potential energy, possessed by a certain mass of water at a certain elevation, in kinetic energy to overcome a certain difference in height. The mechanical energy obtained can be used directly to rotate the shaft of a turbine or in some application or machine that works in hydraulic power. The most common is to use this kinetic energy to generate electrical energy. In this case, we talk about hydroelectric power.

In hydroelectric power, the kinetic energy is…

Kilowatt - Power unit

Kilowatt - Power unit

One kilowatt (kw) is a power unit in current use, equivalent to 1000 watts (w).

One watt (w) is a power unit of the international system equivalent to one joule per second.

If we express the watt in units used in electricity, we can say that a watt is the electric power produced by a potential difference of 1 volt and an electric current of 1 ampere (1 volt ampere).

Frequently the watt hour (Wh) is also spoken as an energy unit. The watt hour is a practical unit of energy equivalent to the energy produced by a power of one watt for one hour.

Converters from direct current to alternate current

At the beginning of photovoltaic solar energy, electrification installations using electricity for consumption at the same voltage and with the same shape as the receiving of photovoltaic solar panels and batteries, ie, 12, 24, 48 V direct current. This made a big difference to users who possessed power distribution network or power generators to 220 V alternate current.

The appliance market has adapted to most users and can find any device to 220 V alternate current. Therefore, getting reliable appliances, quality and reasonably priced operating at low voltage and direct current is…

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…

What is solar thermal energy?

What is solar thermal energy?

Thermosolar energy is a technology to generate electricity or electricity by thermal energy from the Sun (solar heat). It is a type of solar thermal energy. Solar thermal energy is characterized by using solar radiation to heat a fluid. This hot fluid (usually water) can be used for many applications such as heating or hot water (DHW). But another application that can be given is the generation of electric power.

This type of energy is also often called thermoelectric power.

This process of electricity generation takes place in the so-called thermoelectric solar or solar thermal…

Geothermal energy to generate electricity

Geothermal energy to generate electricity

Geothermal energy is that energy that can be obtained by man through the use of heat from the interior of the Earth. This type of energy has many applications. One of these applications is the generation of electric power.

The generation of electricity from geothermal energy is a good complement for hydroelectric plants, which also has the advantage that it is constant throughout the year.

Geothermal plant

Geothermal power plants are the plants responsible for converting geothermal energy into electricity. A geothermal plant is a facility where electricity is generated…

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.

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
