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.

The Sandia Solar Programs e-newsletter features highlights, key activities, events, and publications.

Focused on developing cost-effective, reliable photovoltaic energy systems and accelerating the integration of PV technology in the United States and globally.

Using mirrors to concentrate a large area of sunlight onto a small area where the concentrated light is converted to heat, which drives a generator.


Sandia Labs’ 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 Labs’ 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.

Concentrating Solar Power (CSP)

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.
