Solarthon is GRID Alternatives flagship event and fundraiser showcasing GRID's mission and work in action. At 2016 Solarthon, these three days of fun in the sun brought together hundreds of GRID supporters, job trainees, and clients to install a community solar garden to benefit low-income and energy burdened families in Fort Collins.
