Any implementation of a sustainable photovoltaic solar energy system implies the optimization of the resources to be used. This is the basis of the design and assembly of solar installations to optimize the obtaining of renewable energy.
To achieve an optimal optimization of solar radiation, that is, the use of the Sun, knowledge of the solar path, the profile of the needs and the conditions of the location of the solar panels is essential. All this entails determining the orientation and inclination of the solar panels in fixed installations to achieve the minimum cost of the kilowatt hour of this type of renewable energy.
For reasons of architectural adaptation,…

Thermodynamics is the branch of physics that studies the effects of changes in temperature, pressure and volume of a physical system (a material, a liquid, a set of bodies, etc.), at a macroscopic level. The root "thermo" means heat and dynamics refers to movement, so thermodynamics studies the movement of heat in a body. Matter is composed of different particles that move in a disorderly manner. Thermodynamics studies this messy movement.
The practical importance lies primarily in the diversity of physical phenomena it describes. Consequently, knowledge of this diversity has resulted in enormous technological productivity. Study of thermodynamics

Direct current is a very important type of electric current in solar energy where the direction of circulation of the 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 on three shorter lines (---), for the alternating current that is used instead AC (alternating current) or the symbol (~).
The flow of charges occurs through a conductor, such as a metallic wire. The flow could also be established through a semiconductor, an insulator or even under vacuum as occurs in a cathode ray…

Current intensity is the electrical charge that a section of the conductor passes through a unit of time. The concept of electric current intensity is one of the first and most fundamental concepts of the study of electricity.
The unit of measurement of the current intensity is the A amp in the International System of Units. On the other hand, the instrument used to measure the intensity of the electric current is the galvanometer placed in series with the conductor whose intensity is to be measured. If the galvanometer is calibrated in amps it is called an ammeter.
The electric current intensity is given by the following formula:
I = Q / t

A solar thermal collector, also known as 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 radiation and transforming it into thermal energy. For this reason, this renewable energy source is called solar thermal energy.
The objective of this type of solar panel is to carry out an energy transformation: the solar irradiation experienced by the solar modules is transformed into thermal energy. In some types of solar thermal installations this heat is used to generate steam, and obtain electricity, but it is not the function of the solar collector. On the other hand,…

Photovoltaic solar energy installations connected to the electricity grid are installations where the generated energy is poured directly into the electricity grid. This type of solar installation works as if it were a power plant. Electricity consumption is independent of the energy generated by solar panels. In these cases, the user continues to buy the electric energy that he consumes from the distribution company at the established price and also owns an electric power generating facility.
In the case of adapting these renewable energy installations to a building, it will incorporate a new electrical installation and will have two different electrical installations. On…

Solar energy allows to take advantage of the energy that comes from solar radiation. One way to take advantage of sunlight is to convert the radiation into electrical energy (photovoltaic solar energy) or thermal energy (solar thermal energy). Photovoltaic solar energy requires a chemical process to obtain a continuous current, while solar thermal energy only requires a thermodynamic process.
The characteristics of solar energy imply certain advantages with respect to other sources of energy. Mainly if the other sources of energy are non-renewable energies that come from fossil fuels. But even if solar energy is compared with other sources of renewable energy, some advantages can also…

A photovoltaic solar system connected to the network has only three basic elements: a group of photovoltaic solar panels, an electric inverter, an interconnection panel with the commercial electricity network and an electric meter.
Photovoltaic panels are the most important elements for the use of this renewable energy, they are a type of solar panel whose function is to convert solar irradiation into electrical energy. It is the most important part of the solar system and is common both in systems connected to the grid and in isolated photovoltaic installations.
Electronic inverter or inverter. This device transforms the energy in the form of direct current that the…

Variations in solar radiation (solar variations) is a term that characterizes the changes in the time of the current radiation of the Sun, its spectral distribution and the phenomena that accompany these changes. A distinction is made between the periodic components of these changes, the main one of which is the eleven-year solar cycle, and aperiodic changes. In other words, the solar energy that leaves the Sun and reaches the Earth's surface varies periodically.
There are periodic components such as the eleven-year sunspot and aperiodic cycle. In the last years of the twentieth century, solar activity was monitored thanks to artificial satellites in orbit. Thanks…

Charge controllers or regulators are equipment that controls the voltage and current of a solar panel or wind generator, delivered to the battery park. A charge regulator limits the speed at which electrical current is added or extracted from electric batteries. Avoid overload and can protect against overvoltage. Battery overload may reduce battery performance or life, and may pose a safety risk.
The charge controller can be supplied in the form of a separate device (for example, an electronic unit in a wind turbine or in a photovoltaic solar energy system) or in the form of a microcircuit for integration into a battery or charger. Independent charge regulators…

In climatology the term global warming indicates the change in the climate of the Earth developed in the twentieth century and still ongoing. This change is largely attributed to emissions into the Earth's atmosphere of increasing amounts of greenhouse gases, and other factors that the scientific community has been identified as attributable to human activity.
In the course of Earth's history, there have been several variations of climate that have led the planet to cross different eras of ice alternated with warmer periods called interglacial eras. These variations are mainly due to periodic changes in the orbital design of our planet, with disturbances due to the periodic…
