SPI Solar

SPI Solar, Trimark, and NREL are partnering to optimize the thermal and optical performance of parabolic trough receivers—critical components of concentrating solar power (CSP) plants.

Receivers in CSP plants take a lot of abuse, from dramatic temperature changes to numerous mechanical stresses. Finding ways to make the receivers more resilient and optimize their performance under these conditions can lead to big improvements in the overall efficiency of CSP plants.
