What is the meaning of concentrated solar power?

Concentrating solar power (CSP) plants use mirrors to concentrate the sun’s energy to drive traditional steam turbines or engines that create electricity. The thermal energy concentrated in a CSP plant can be stored and used to produce electricity when it is needed, day or night.

What is concentrated solar power and how does it work?

Concentrating Solar Power (CSP) technologies use mirrors to concentrate (focus) the sun’s light energy and convert it into heat to create steam to drive a turbine that generates electrical power. CSP technology utilizes focused sunlight.

Why is concentrated solar power important?

CSP systems harness thermal energy from the sun and use this energy to create electricity or heat. This thermal energy can be easily and efficiently stored in tanks so it can be used whenever the energy is needed to meet demand, not just when the sun is shining.

What are the limitations of concentrated solar power?


  • Intermittent.
  • Low energy density.
  • Construction/installation costs are high.
  • They require a considerable amount of space.
  • Manufacturing processes often create pollution.
  • Heavily location dependent.
  • Will involve significant transmission distances/losses.

What is the definition of heliostat?

: an instrument consisting of a mirror mounted on an axis moved by clockwork by which a sunbeam is steadily reflected in one direction.

How much does a heliostat cost?

Although current heliostat cost data is not publicly available, costs are beginning to fall rapidly with experience of building plants. Costs were estimated around 150-200 USD/m2 in 201311, but are now more likely to be in the 100-150 USD/m2 range.

What are 5 advantages of solar energy?


  • Solar power is pollution-free and causes no greenhouse gases to be emitted after installation.
  • Reduced dependence on foreign oil and fossil fuels.
  • Renewable clean power that is available every day of the year, even cloudy days produce some power.
  • Return on investment unlike paying for utility bills.

What are the benefits of a concentrated solar power?

The Benefits of Solar Energy Sustainable. The advantage of solar energy is that it is a sustainable alternative to fossil fuels. Low Environmental Impact. Solar energy has a substantially reduced impact on the environment compared to fossil fuels. Energy Independence.

How does concentrated solar power produce electricity?

Concentrating solar power plants produce electric power by converting the sun’s energy into high-temperature heat using various mirror configurations. The heat is then channelled through a conventional generator.

How good is solar power compared to wind power?

Generally speaking, solar energy seems to be more superior than wind. But that doesn’t make it the clear winner. This is because, for some places, wind energy might actually be a better fit than solar. Basically, both solar energy and wind energy are good alternatives for the production of energy. They can be useful in their own time and place.

Is hydroelectric power better than solar power?

Hydropower is a more reliable source of energy than solar power because it has a steady supply of power, while solar power is an intermittent energy source with periods of time when the energy supply is interrupted, such as at night and on overcast days.
