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 [...]

SunShot

Key Activities Sandia’s research in solar photovoltaics (PV) and concentrating solar power (CSP) helps advance the mission of the U.S. Department of Energy's SunShot Initiative to decrease total cost of solar energy systems by 75% by 2020 and make solar energy cost-competitive with other forms of electricity generation without subsidies. Sandia researchers address [...]

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 [...]

CSP Software & Tools

DELSOL DELSOL is a performance and design code that includes optical and economic analyses. An analytical Hermite polynomial expansion/convolution-of-moments method is used to predict flux images from the heliostats in a computationally efficient manner (typically much faster than either MIRVAL or HELIOS). The code accounts for variations in insolation, cosine forshortening, shadowing and blocking, and [...]

PV Value®

The PV Value® tool is now being developed and maintained by Energy Sense Finance, LLC, with funding provided by the DOE SunShot Small Business Innovative Research program. The tool is still free, though improved with a design to support multiple web browsers and mobile devices, including tablets and smartphones. The spreadsheet version of PV Value® [...]

Concentrating Solar Power (CSP)

The Concentrating Solar Power (CSP) program conducts research to reduce costs and identify opportunities for improvement of CSP technologies, advance understanding of CSP system behavior, increase efficiency and capacity for baseload CSP applications, and reduce risk for CSP technologies and increased levels of concentrating solar power in the transmission grid. The program also [...]

Central Receiver Test Facility

Operated by Sandia National Laboratories for the U.S. Department of Energy (DOE), the Central Receiver Test Facility (CRTF) is a major location for developing technology to produce electricity from the heat of the sun's energy. This technology is expected to be commercially competitive with other energy sources. The primary goal of the CRTF is to [...]

R&D Activities

The first step in a concentrating solar power system is to “collect” and focus the sunlight using a large array of mirrors, or collectors. Different configurations of mirrors can be used depending on the type of CSP technology being employed. CSP system technologies include dish, parabolic trough, linear Fresnel, and central receiver (power tower) systems. [...]
