METEOROLOGY – WIND ENERGY & RENEWABLE METEOROLOGY CALCULATOR
Concentrated Solar Dni
A precise tool.
What is the Concentrated Solar Dni & How does it work?
Concentrated Solar Power (CSP) plants utilize mirrors to concentrate sunlight onto a receiver, which then converts the heat into electricity. The Direct Normal Irradiance (DNI) is a crucial parameter that determines the amount of solar energy available for conversion.The output power of a CSP plant is directly proportional to the mirror area, DNI, and conversion efficiency. Higher values in these parameters lead to increased energy production.
P = A times DNI times eta
P = CSP plant output power (kW)
A = Mirror area (m²)
DNI = Direct Normal Irradiance (kW/m²)
eta = Conversion efficiency (decimal)
A = Mirror area (m²)
DNI = Direct Normal Irradiance (kW/m²)

Frequently Asked Questions
What is Direct Normal Irradiance (DNI)?
Direct Normal Irradiance (DNI) is the solar power received per unit area by a surface that is always perpendicular to the sun’s rays.
How does mirror area affect CSP plant output?
The larger the mirror area, the more sunlight can be concentrated, leading to higher output power from the CSP plant.
What is conversion efficiency in a CSP plant?
Conversion efficiency refers to the percentage of solar energy that is successfully converted into electricity by the CSP plant’s receiver.
How do I calculate the output power of a CSP plant?
Multiply the mirror area by the DNI and the conversion efficiency to get the CSP plant’s output power in kilowatts.
What units are used for DNI in this calculation?
DNI is measured in kilowatts per square meter (kW/m²) in this calculation.
Can I use this calculator for any type of solar power plant?
This calculator is specifically designed for Concentrated Solar Power (CSP) plants that use mirrors to concentrate sunlight.
What factors can reduce the DNI value?
Factors such as atmospheric conditions, dust, and weather patterns can reduce the DNI value received by a CSP plant.
