It is said to be the largest in the world and measures 500 square meters and supplies electricity to a hospital.

What is a solar concentrator. These devices use mirrors or lenses to focus a large amount of sunlight onto a small receiver that uses the heat to generate steam, which in turn drives a turbine, which produces electricity.

In addition to solar towers and parabolic dishes, parabolic troughs and Fresnel collectors are common, which concentrate light into a tube that passes in front of the mirrors.

The SG4 Big Dish is made of polished aluminum and has 380 hexagonal mirrors. The secret of its efficiency is in its motors, which direct it towards the sun with a precision of 0.01º.

While the wind industry makes ever larger wind turbines, the solar industry plays with growing disk concentrators.

The SG4 Big Dish is capable of lighting a small hospital. Developed by Australian researchers, it has a reflectivity of 94% with which it reaches 150 kW of power, enough to supply electricity to a rural hospital.

The trick is not only to concentrate the radiation at the focal point in front of the mirror, but to chase the sunlight with an advanced mechanism of electric motors that directs it with a precision of 0.01 degrees.
