Night Time Solar

In the solar Gemasolar central, a cloudy sky is no reason for depression: thanks to the aunique technology, the energy stored during the sun shines is used to produce electricity at night or on rainy days.

The site has been operational since May 2011, has not gone unnoticed in the plains of Andalusia, in southern Spain.

From the motorway between Seville and Cordoba, you can observe the tower within which 2650 solar panels of 120 square meters each lit up, arranged in a huge circle of 195 hectares.

“This is the first plant in the world who works 24/24, a solar power plant that operates day and night!” says Santiago Arias, technical director of Torresol Energy, which manages the facility.

“Its mechanism is very easy to explain,” he promises, “the panels that reflect the sun’s rays towards the tower generate an amount of energy that’s equivalent to 1000 times of what we have on the ground.”

The energy is stored in a tank filled with molten salt at a temperature greater than 500 degrees. Salts are used to produce steam to turn a turbine and produce electricity as well as in a conventional thermal plant.

  1. This is a good innovation to further harness the sun's energy for the betterment of humankind. What makes it a better system is that it can still store solar energy even at night time. Amazing! Brisbane solar
