I'm working on a project to see what kind of solar experiments we can add to our curriculum. I'll be looking at different combinations of loads and supplies on my workbench. To make sensible comparisons between different device configurations, I need some baseline figures on available light in different environments. Here ia a bit of raw data that will be essential in comparing the behavior of different devices under different lighting conditions.
Light intensity measurements made with with a Sekonik Studio Deruxe II meter (Thanks, Anna). Outdoor measurements made noon, February 19, 2010 at Chicago, IL, 41.88 deg North. (Ed Bennett, email@example.com)
