We conduct research and development (R&D) in solar power, including photovoltaics and concentrating solar power, to strengthen the U.S. solar industry and improve the manufacturability, reliability, and cost competitiveness of solar energy technologies and systems.
Sandia’s solar photovoltaic (PV) work is focused on developing cost-effective, reliable photovoltaic energy systems and accelerating the integration of PV technology in the United States and globally. The lab’s PV department provides the technical lead for systems integration and balance-of-systems manufacturing technologies as well as technical support to the U.S. Department of Energy (DOE) in deployment and validation of PV systems for federal agencies, utilities, and other institutional users. Sandia assists industry and users by providing technical assistance, accurate performance measurements, component development and improvement, and system evaluation. A major thrust of the department is to evaluate and improve the performance, reliability, and cost effectiveness of systems and balance-of-systems components.
Sandia’s PV research staff work collaboratively with DOE’s Solar Energy Technologies Program, the U.S. photovoltaic industry, other government agencies and national laboratories, and international organizations to increase the worldwide use of PV power systems by reducing cost, improving reliability, increasing performance, removing barriers, and growing markets.
The solar photovoltaics (PV) industry has advanced significantly in recent years, yet the PV world of tomorrow has only been imagined. Sandia National Laboratories contributes to the advancement of PV technology through research in advanced PV technologies, such as III-V thin cells, and advanced small and thin c-Si.
Sandia National Laboratories supports SETP’s goals by defining and applying procedures for evaluating performance, supporting development of new and improvement of existing technologies, and providing skilled testing and evaluation of all PV components, including cells, modules, inverters, and Balance-of-Systems (BOS).
Sandia’s Market Transformation efforts exist at the intersection of technology, economics, and policy & regulations. We address market barriers and transactional costs of solar projects across the United States.
Concentrating Solar Power (CSP) uses mirrors to concentrate a large area of sunlight, onto a small area. Electrical power is produced when the concentrated light is converted to heat which drives a generator.
In virtually all applications CSP is large power, on the order of 100 MW or larger, that is used by utilities to generate electricity and distribute to consumers. In a CSP plant, solar energy is converted to heat and the heat is used in a conventional power cycle or other heat engine to produce mechanical power and drive a generator.
The Sunshine to Petrol (S2P) program seeks to create a sustainable liquid fuels solution that can replace petrolium-based fuels on a large scale. Work currently centers on the production of synthetic fuels from carbon dioxide using solar energy.
Sandia’s Sunshine to Petrol (S2P) team seeks to address the critical national and global issues of growing energy consumption amid increased vulnerability and price volatility of petroleum supplies and climate change risks. The transportation and industrial sectors in the United States are deeply dependent on petroleum, a dominant energy source for these sectors and a driver of greenhouse gas emissions. An alternative energy carrier coupled to a sustainable energy source that can be used within existing infrastructure, distribution, and traditional petroleum-based combustion systems is necessary to assure national security, enhance U.S. economic competitiveness, demonstrate leadership in mitigating the risks of climate change, and promote a smooth transition to an energy-secure and diversified transportation mix.
A research team that included Sandians Clifford Hansen and Joshua Stein (in Sandia’s Photovoltaic & Distributed Systems Integration Dept.) and Katherine Klise (in Sandia’s Geotechnology and Engineering Dept.) received a Best Paper Award for their […]
Sandia National Laboratories/Tigo Energy researchers recently submitted an application for a US patent related to research on arc-fault detection and circuit interruption in solar photovoltaic (PV) systems. Sandia’s patent-pending methods, filed as Identifying an Arc-Fault […]
The state of the art in PV system monitoring is relatively simplistic, relying either on comparisons of outputs between various parts of the system (e.g., inverters) or on an evaluation of a performance metric that normalizes […]
SolarReserve is testing engineering units at the National Solar Thermal Test Facility (NSTTF) operated by Sandia. The company says it decided to test its prototype heliostats at NSTTF because of Sandia’s, “knowledge and reputation in […]
