This semester in the yard, we are putting up panels on roofs, and other groups are working on setting up isolated systems on trainer carts. We seem to do a lot of standing there scratching our heads and looking at schematics. Then we get it done. Power from the sun. No coal exhaust.

My team on the roof rules. Lot's of good balance to everyone's different strengths.
