In 2009, after meticulously building and installing our own solar home systems we purchased ~600 very robust pre made solar kits. Our ATC made kits lasted 7 years before needing new batteries but many of the kits we ordered in 2010 are still working! We tested over 30 samples to get to the kits we now use.

We started teaching solar in 2009. Over time we started to have woman only classes which attracted a lot more women to our STEM intensive program. This class is from 2012 in Santa Cruz la Laguna at the CECAP trade school. The teacher is Carlos Alverez, a gifted electronics teacher.

Our new dehydrators will be delivered to an organic farming coop on Saturday. The coop has experience working with our past dehydrators and they have their own special recipes for things like granola bars.
