Megawatt-class dish solar power generation

What is a dish/engine system?

The dish/engine system is a concentrating solar power (CSP) technology that produces smaller amounts of electricity than other CSP technologies—typically in the range of 3 to 25 kilowatts—but is beneficial for modular use. The two major parts of the system are the solar concentrator and the power conversion unit.

How does a solar dish direct steam power generation system work?

A solar dish direct steam power generation system was established based on gradient TES, which included a dual sensible heat tank using molten salt (60 % NaNO 3 -40 % KNO 3), latent heat storage using KNO 3 as PCM, and an intermediate tank for molten salt flow regulation.

Which solar dish system is best for high-temperature applications?

The high concentration often corresponding to high radiation flux and temperature, which means high energy conversion efficiency and a wide range of application scenarios. Therefore, solar dish systems (SDSs) with the highest concentration are one of the few choices in many high-temperature application fields.

How does a solar dish work?

The resulting beam of concentrated sunlight is reflected onto a thermal receiver that collects the solar heat. The dish is mounted on a structure that tracks the sun continuously throughout the day to reflect the highest percentage of sunlight possible onto the thermal receiver.
