Teambuilding solar workdays

Give your team a fun and educational experience installing solar for a local family. We offer custom sponsorship packages for companies wishing to sponsor workdays in multiple locations or multiple homes at one time.

Executive team builds

Executive wordays are a great way to improve communication and cooperation among your company's top leaders while putting your corporate values into action. These workdays are highly customizable for busy schedules!


Solarthon is GRID Alternatives' signature fundraising event and solar block party where hundreds of sponsors, volunteers and job trainees come together to install solar for multiple families in a single event. Solarthon sponsors can sponsor a home for their employee volunteers or partners, or provide general event sponsorship.
