Solar Panels in Seattle

Explore solar energy production data from the University of Washington demonstration facility!

Coming soon: On-site solar radiometer data. The radiometer will measure the amount of sunlight hitting the solar panels throughout the day.

Solar production in the last five days:

The Power Plant building on the UW Seattle campus holds an installation of three types of solar panels: monocrystalline silicon, polycrystalline silicon and thin film cadmium telluride. Our monitors track how much power is produced by each panel every 15 minutes. What does the above graphic tell us?

Our data archive

You can see the entire year's worth of data at once for: 2012 and 2013. (Please note, these pages are graphic intensive and may take some time to load.)

A month at a time: 

2013: Jan | Feb | Mar | Apr | May | Jun | Jul | Aug | Sep |

2012: Jan | Feb | Mar | Apr | May | Jun | Jul | Aug | Sep | Oct | Nov | Dec

We encourage you to consider:

What causes the variations throughout the day? (Ex. clouds, temperature, etc.)

Why do the different types of solar panels respond differently at times?

How does the power output change with the seasons and over time?
