The SRML supplies high-quality, reliable information on the Northwest’s solar resources for the purpose of planning, designing, deploying, and operating its solar energy systems. In collaboration with business and government, the goal of the lab is to help the region leverage its solar energy potential.

SRML network features:

• Monitors solar radiation at 30 sites in the Northwest.
• Monitors and evaluates the performance of more than ten photovoltaic systems.
• Creates and maintains an extensive solar radiation database for the Northwest.
• Develops and evaluates tools to facilitate the deployment of solar energy systems.
• Calibrates solar irradiance sensors.
• Evaluates outdoor performance of PV cells and modules.
