Solar energy<\/strong> is a renewable source that uses solar radiation to generate electricity or heat. The basic principle entails capturing sunlight and heat using specific devices and transforming them into useful energy for domestic, industrial and large-scale power generation applications. <\/p>\r\n

There are several different solar technologies<\/strong>:<\/p>\r\n<\/div>\r\n<\/div>\r\n\r\n

\r\n
\r\n
\r\n

1. Photovoltaic solar power<\/span><\/h2>\r\n<\/div>\r\n<\/div>\r\n<\/div>\r\n\r\n
\r\n
\r\n

This technology converts sunlight directly into electricity using the photovoltaic effect. The panels used are made up of semiconductor cells (silicon) which release electrons when struck by the photons, thus generating direct current (DC). An inverter is used to transform this current into alternating current (AC) for domestic use or export to the grid. The systems can be:<\/p>\r\n

    \r\n\t
  • \u2022\tGrid-connected<\/strong>: surplus power is exported to the power grid.<\/li>\r\n\r\n\t
  • \u2022\tOff-grid<\/strong>: require batteries for storage.<\/li>\r\n\r\n\t
  • \u2022\tHybrid<\/strong>: combine grid uptake and storage.<\/li>\r\n\r\n<\/ul>\r\n

    The efficiency of the solar panels depends on the quality of the silicon (monocrystalline, polycrystalline or amorphous) and factors such as orientation, tilt and solar radiation. <\/p>\r\n\r\n\r\n<\/div>\r\n\r\n\r\n\r\n\r\n

    2. Solar thermal energy<\/span><\/h2>\r\n<\/div>\r\n<\/div>\r\n<\/div>\r\n\r\n

    Solar thermal systems use solar radiation to generate heat, mainly for domestic hot water, heating and industrial processes. Components include:<\/p>\r\n

      \r\n\t
    • \u2022\tSolar collectors<\/strong> (flat plates or vacuum tubes) that absorb the radiation.<\/li>\r\n\r\n\t
    • \u2022\tCircuit<\/strong> through which the heat transfer fluid (water or glycol mixture) is piped.<\/li>\r\n\r\n\t
    • \u2022\tAccumulator<\/strong> for storing heat. In advanced applications, the heat can be used to produce steam and generate electricity in solar thermal plants. There are low temperature systems<\/strong> (for domestic use) and high temperature systems<\/strong> (for industrial use), with the possibility of storage in molten salts<\/strong> to guarantee supply even when the sun is not shining. <\/li>\r\n <\/ul>\r\n\r\n\r\n<\/div>\r\n<\/div>\r\n\r\n
      \r\n
      \r\n
      \r\n
      \r\n

      3. Concentrated solar power (CSP)<\/span><\/h2>\r\n<\/div>\r\n<\/div>\r\n<\/div>\r\n\r\n
      \r\n\r\n\r\n
      \r\n

      CSP uses mirrors or lenses to concentrate sunlight onto a receiver, which can reach temperatures of over 1,000\u202f\u00b0C. It can be used to heat a fluid (water, oil or molten salt), producing steam which drives a turbine and generates electricity. The main types are:<\/p>\r\n

        \r\n\t\t
      • \u2022\tParabolic trough<\/strong>: curved mirrors concentrate light onto receiver tubes.<\/li>\r\n\r\n\t
      • \u2022\tSolar power towers<\/strong>: mirrors (heliostats) reflect the sunlight onto a receiver mounted atop a tower.<\/li>\r\n\r\n\t
      • \u2022\tParabolic solar dishes<\/strong>: the light is concentrated onto a focal point for specific applications. The great advantage is the possibility of thermal storage, which allows continued production of electricity, even at night. <\/li>\r\n\r\n\r\n <\/ul>\r\n

        Among the advantages<\/strong> of solar power, it relies on an inexhaustible source (sunlight), limits greenhouse gas emissions and contributes to energy independence. In addition, it can be used for diverse applications, from domestic self-consumption to large industrial installations, and requires relatively little maintenance.<\/p>\r\n

        However, it does have some drawbacks<\/strong>. The initial installation cost is high and requires adequate space and good orientation. Production is intermittent and depends on solar radiation, which makes it necessary to install storage or backup systems. <\/p>\r\n\r\n\r\n<\/div>\r\n
