Degradation Signature Characterization
The data from the characterization of parts before and after stress testing will be analyzed for useful fingerprints that indicate degradation and remaining lifetime. One approach is to apply the characterization results to simulations to look for corresponding changes in behavioral parameters of the inverters. Figure 1 describes one potential behavioral parameter, voltage […]

Goal 1: Degradation Study of Components and Subsystems

Thermal Management Subsystem
Thermal management of inverter systems and internal components is critical for ensuring lasting performance reliability. Research is currently being carried out to more accurately characterize inverter components and system topologies of varying scales. This work includes:

Thermal/fluid phenomena of internal inverter components, and their impact on electrical performance and reliability.

Finite Element Analysis (FEA)/Computational Fluid […]

Areva Solar and Sandia Labs Join Forces for CLFR Molten-Salt Storage

Areva Solar is collaborating with Sandia National Laboratories on a new concentrated solar power (CSP) installation with thermal energy storage. The CSP storage project combines Areva’s modular Compact Linear Fresnel Reflector (CLFR) solar design with Sandia Labs’ proven molten-salt storage system. This will be the first CSP integration with Sandia Labs’ Molten-Salt Test Loop System […]

Power Towers for Utilities

Desirable Features of Power Towers for Utilities
Because of their practical energy storage, solar power towers have two features that are particularly desirable for utilities: flexible capacity factors and a high degree of dispatchability.
Power towers can be designed with annual capacity factors up to 60 percent, and as high as 80 percent in summer when the […]

NASA’s Solar Tower Test of the 1-Meter Aeroshell

This test is part of a series in support of NASA’s In-Space Propulsion Technologies (ISPT) program. An aeroshell allows a spacecraft to use friction from a planet’s or moon’s atmosphere as a braking force—allowing the probe to carry less fuel (for braking rockets) and permitting that now-available space and mass to be used for mission-relevant […]
