everyone has questions regarding working of solar panels at night and how do they fulfill their electricity needs at night from solar panels.
The solar panel generates photons which then convert it into electricity, these photos will be generated when solar panel comes in contact with sun light. during night time there is no any other medium is available for a solar panel to generate electricity.To fight with this issues we have batteries and grid utility system available.Many people now live in the rural areas are uses a solar battery to store extra electricity at day time and consumes it at night time.Peoples living in urban areas are using grid utility system to get his solar generated electricity from the utility grid. As the backup system with batteries is not a good option to use because of its disadvantages. It is a too costly solution and only used in small rooftop small solar projects. Grid utility is also a good option to get stored energy back at night but it also has some disadvantages. As due to human evolution technology is also going bigger and better. researchers have come with ideas to get solar energy at night.these two solar energy parks which are getting solar energy at night.

Let’s check How These Solar Power Plants Gets Solar Energy At Night?

PS10 Solar Thermal Power Tower

This plant located in Spain is world’s first concentrating solar power which is able to produce solar energy at night.
During day time it operates in the same way as other plant works, its use sunlight to contact with the panel and generates electricity.
During the night it uses its salt battery to get energy.It is not actually a battery, though.These types of solar power plant concentrate hot sunlight through a collector, which then eventually transfer heat to molten salt where it is stored for night use.
The stored molten salt is later used to help boil water at night and which run a turbine to generate electricity.

Andasol Solar Power Station

Like another solar power plant, it also stores solar energy during daytime and use it at night and generate electricity from thermal energy. the 150 Mw of concentrated solar power plant uses parabolic troughs. The parabolic mirrors are mounted with a small tube filled with liquid fluid is attached to it.
parabolic-trough mirrors are a solar collector, they concentrate sunlight on tubes which warm oil liquid to more than 400-degree Celsius which then used to boil the water which spins a turbine to generate electricity from the thermal process.
As these solar collectors are big enough to collect twice as much sunlight as plants needt o operate during day time. The backup or extra generated heated oil is sent to the heat exchanger. the hot moltan salt is used as backup during night which generates electricity by boiling water.
