Heliostats, movable mirrors, were used to concentrate the sun's rays on a central tower of initially water, and later, salt.
Solar One and Solar Two were test sites, and neither operates anymore. The array of mirrors has been converted to be part of a gamma ray telescope (the mirrors now focus the brief and very weak flashes of light generated by cosmic gamma rays as they enter the earth's atmosphere onto a detector).
Another plant, Solar Tres, (later Gemasolar) was built in Spain, using the technology of Solar One and Solar Two, and three times bigger. Its molten salt storage means it can run during 15 hours of darkness. During the summer of 2013 the plant ran 24/7 for 36 consecutive days.

Solar ovens focus the sun's rays by using reflective surfaces, such as mirrors or aluminum panels, that concentrate and direct sunlight onto a cooking chamber. This increases the intensity of the sunlight within the oven, allowing it to reach high temperatures for cooking.
Another names for solar rays is UV rays.
Ultraviolet rays are generally considered a harmful disadvantage of solar energy. These rays cause damage to the solar panels over an extended period of time.
Solar power has its roots dating back to the 7th century B.C. when magnifying glasses were used to concentrate the sun's rays to create fire. However, the modern development of solar power began in the 19th century with the discovery of the photovoltaic effect by Alexandre Edmond Becquerel in 1839.
light rays
They contain more solar energy!
"The solar rays are hotter on the equator than in the northern hemisphere."
solar flares appear as a dark spot
there is always going to be wind and solar rays
Because vertical solar rays are less oblique during Sumner and are concentrated over smaller areas
