## Charge Controllers

Although in principle it seems that in an installation of photovoltaic solar energy just need solar modules and batteries, there is a key element in these facilities is what ensures that, in the charging process as in the discharge accumulators, is made so that they are always within the correct operating conditions: the charge controller.

Solar panels are designed so that they can give a higher than the end voltage battery charging voltage. This ensures that the solar panels are always able to charge the battery, even when the temperature of…

## Rated Voltage

In electricity, the rated voltage of an electrical device is the voltage that must not be exceeded in normal operation. The nominal adjective is because that tension usually serves to characterize the device, to name it. The nominal value indicates the theoretical or ideal value of anything that can be quantified, as opposed to the real value, which is what is obtained in a given measurement.

Another definition of rated voltage: The rated voltage is the specific potential difference for which a device or installation is designed.

As it is a nominal value it implies that the voltage…

## Photovoltaic Panel

A photovoltaic panel is a type of solar panel designed for the use of photovoltaic solar energy. Its function is to transform solar energy into electricity.

Photovoltaic panels can be used to generate electrical power in both domestic applications and commercial applications.

The photovoltaic modules are formed by a set of interconnected photovoltaic cells. The photovoltaic cells that make up a photovoltaic panel are embedded and protected. The photovoltaic panel is in charge of directly transforming the energy of solar radiation into electricity, in the form of direct current.

## Volt - Voltage Unit

The volt is the international system unit measures for measuring electromotive force and voltage.

The volt is represented by the symbol V. The measuring instrument for measuring voltage is the voltmeter.

Two different definitions of volt can be given:

On the one hand, we can consider that a volt is the voltage between two points of a conductor through which passes a current of one ampere (A) and a power of one watt (W) is dissipated.

Another alternative way to define it: The volt is equivalent to the potential difference that exists between two points of a conductor…

## Converters From Direct Current To Alternating Current

In the beginnings of photovoltaic solar energy, the electrification facilities used electricity for consumption at the same voltage and with the same form that they received from photovoltaic solar panels and accumulators, that is, at 12, 24, 48 volts in direct current. This made a big difference with the users who had electricity distribution network or generator sets at 220 volts alternating current.

The appliance market has adapted to the majority of users and we can find any appliance with 220 volts of alternating current. Therefore, getting reliable, quality, and reasonably…

## Solar Panel

A solar panel is a device to take advantage of solar energy. It can also be called a solar module.

Photovoltaic solar panels contain a set of solar cells that convert light into electricity. It is called solar because the sun is one of the strongest energy sources for this type of use. Solar cells are sometimes called photovoltaic cells, and photovoltaics literally means "light-electricity". Solar cells have the photovoltaic effect to absorb the sun's energy and cause electrical current to flow between two charged layers in the opposite direction.

The denomination of solar panel…

## Watt 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 unit 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,…
