Pratt Whitney Rocketdyne Testing

On November 24, 2012 the National Solar Thermal Test Facility (NSTTF) began testing of the Pratt Whitney Rocketdyne (PWR) solar receiver shroud.  Fifteen days of solar testing are scheduled for this testing.  The flux levels on the shroud range between 100 and 500 suns.  The work is sponsored by PWR in cooperation with the Department […]

Dish Test Facility

This area of the site allows industry partners to install full-scale solar dishes for long-term reliability testing and evaluation. There are currently ten SES dishes and six Infinia dishes at this location. The site also includes two SNL-developed solar dishes that are available for research. Solar dishes can be used for the high-temperature portions of […]

Regional Test Facility

Sandia (with DOE support) recently installed infrastructure on eight acres of the National Solar Thermal Test Facility (NSTTF) to support US industry in actual field test and validation of US-based PV modules and systems designs to accelerate bankability assessments. The initial phase has 1 MWe connectivity to the utility system. The second phase, an additional […]

Solar Tower

The tower is a 61 m (200 ft) high concrete structure with three test locations on the north side and the top of the tower. The tower can support testing for CSP experiments and large-scale, high-flux materials samples. The equipment in the tower includes a 100-ton capacity elevating module for lifting experiments to the top […]

Heliostat Field

The heliostat field has 218 individual heliostats. This capability directly supports the SunShot goals by providing flux levels of greater than 300 W/cm2 and total power in excess of 6 MWt. Each heliostat has two motors and two drives (one azimuth and one elevation), one 480 V power box, one electronics box, and one control box […]

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 […]

Solar Resource Assessment

Solar resource is one of the most important inputs to PV power plant yield and performance evaluations. It is also one of the most difficult quantities to measure and estimate accurately.

Sandia’s Solar Resource Assessment program researches and develops models and algorithms for estimating, predicting, and forecasting the solar resource. Current research efforts at Sandia include

understanding […]
