What types of solar energy exist?

From the energy point of view, it is one of the renewable sources whose installation, management, and use are more accessible to people or companies. In fact, photovoltaic Solar energy in Pakistan seeing an increase in its use in the most favorable climatic zones, and even with the recent subsidy plans, the facilities for using it for self-consumption have increased.

Depending on its origin and how it is processed, there are different types:

This system takes advantage of the heat input provided by the Sun. Solar radiation is converted into thermal energy to heat a fluid that can be used for various uses such as heating or domestic hot water. Regarding solar power plants, two types must be highlighted: thermoelectric, which heat afluid to obtain water vapor and move the turbine that generates electricity; and photovoltaic parks , which control the reaction of silicon that converts light into electrons.

  • Photovoltaic Solar Energy

It is a type of renewable, inexhaustible and non-polluting energy that can be produced in installations with photovoltaic solar panels . One of the great advantages of this technology is that it is modular: the panels can be used for self-consumption (provide electricity in homes or buildings) or also to supply the electricity grid through large power plants.

  • passive solar energy

Passive solar energy directly uses direct energy from the sun without making any transformation. Therefore, it is not necessary to use any electrical device to transform one current to another and to accumulate energy, as is the case with active energy of the other two types previously explained.

Solar energy technologies through history

Photovoltaic energy is the most widespread in large installations or solar farms, and its panels directly transform solar radiation into electrical energy through the photovoltaic effect . It was the French physicist Edmond Becquerel who discovered it in 1839 when he realized that a cell with metal electrodes produced more electricity through a conductive solution when exposed to light .

There are operational tests with materials derived from carbon in organic panels, which provide advantages such as the possibility of adapting them to irregular surfaces. This could make it easier and cheaper to install, for example, in urban environments and for domestic use.

The first photovoltaic module was developed in 1954 by NASA engineers to power satellite communication equipment with sunlight. In the mid-seventies, photovoltaic advances reached the civil sphere, although the capacity of those modules was much lower than that of the current ones.

A convincing stimulus: the price

As in most renewable sources, the rise of solar energy is associated with its cheapness. The great barrier that prevented its development until a few years ago was the cost of technological investment. But this difficulty has been overcome thanks to innovation and economies of scale.

Photovoltaic plants usually connect to the grid to pour all the electricity they generate. Also generators for self-consumption: excess energy that is not used to supply a home or business is channeled to the grid. However, other photovoltaic installations work without this connection, for example, those that generate energy for agricultural uses (irrigation, machinery, lighting, etc.) in isolated places.

Better Management, more efficiency

Technological advances have not only managed to reduce installation, operation and maintenance costs, but they have also multiplied management capacity through remote monitoring of performance and technical incidents or the traceability of electrical energy to certify its 100% renewable origin, something fundamental for the consumer and for the financing of projects with a guarantee of being sustainable.

Likewise, this technological evolution has boosted the efficiency and performance of Sunlife solar panels, that is, in the use of a greater percentage of sunlight that falls on the cells and is finally converted into electricity.
