This paper presents a model for PV education that brings together photovoltaics engineers with 6th-12th-grade students and teachers to test agrivoltaics applications using citizen science. A summer research experience program engaged high school students in building a novel agrivoltaics school garden monitoring system, facilitated by PV engineering researchers and education scholars. The high schoolers are mentoring middle grade students as they design and install school gardens and collect data on garden conditions with and without solar panels covering crops. Ideas for multi-generational collaboration are explored.
