Solar energy is that produced by the Sun’s light – photovoltaic energy – and its warmth – solar thermal – for the generation of electricity or the production of heat. Inexhaustible and renewable, since it comes from the Sun, solar energy is harnessed using panels and mirrors.

Photovoltaic solar cells convert sunlight directly into electricity by the so-called photovoltaic effect, by which certain materials can absorb photons (light particles) and liberate electrons, generating an electric current. Alternatively, solar thermal collectors use panels or mirrors to absorb and concentrate the Sun’s heat, transferring it to a fluid and conducting it through pipes to use it in buildings and installations, and for electricity production (solar thermoelectric).

The added benefits of solar other than cutting energy bills is solar energy has the least negative impact on the environment compared to any other energy source. You can sell unused energy back to the grid.
