Solar panels for homes and businesses.

Sunlight consists essentially of small packets of energy called photons. Photons contain different amounts of energy depending on the wavelength of the solar spectrum. For example, blue light or ultraviolet light has more energy than red or infrared light. 

When photons strike a photovoltaic cell, some are reflected, some pass through it, and others are absorbed by the photovoltaic cell. These last photons are the ones that produce electric current. These photons cause the electrons in the photovoltaic cell to move to another position and, as we know, electricity is nothing more than the movement of electrons. 

This simple principle of physics is the basis for one of the most advanced electricity-generation technologies of our time.

Photovoltaic systems, which convert solar radiation into electricity, are considered ideal energy conversion systems because they use the planet’s most readily available energy source (the sun) to generate electricity, the most useful form of energy. Solar energy is clean, inexhaustible, gentle and renewable. 

Solar radiation is not controlled by anyone and is an inexhaustible domestic energy resource that provides independence, predictability and security in energy supply. Photovoltaic systems give consumers complete control and immediate access to information about the energy produced. This makes them more mindful of how they consume energy and thus helps promote its rational use and conservation. 

Since solar electricity is produced and consumed locally, significant losses in electricity transmission and distribution are avoided, resulting in energy savings of 10% compared with conventional electricity supplied through the grid. 

Solar photovoltaic systems operate quietly, are reliable and have a long lifespan. They can be expanded to meet changing needs, and the energy they produce can be stored (in the grid or in batteries). They require minimal maintenance.
