Solarthon is a solar installation block party and fundraiser, where volunteers come together to install solar for a community that needs it most. Solarthon brings together people from all walks of life - individual fundraisers, corporate sponsors, job trainees, community leaders and the homeowners themselves - to install solar electric systems for multiple low-income families in a single neighborhood.

A group of over 100 volunteers, corporate partners, community leaders, and job trainees celebrate at Solarthon.

Solarthon is our largest community installation event of the year!

Fun for Everyone

Participants get hands-on experience installing solar for local families, network with other solar enthusiasts and solar installation companies, and have fun while making a difference in their community. For corporate sponsors, the event is an opportunity to demonstrate their commitment to environmental and community sustainability.

The Benefits of Sponsorship

Sponsor a house for your employee volunteers or for a team of job trainees from one of our local partners. Sponsorship benefits can include prominent signage, logos on event marketing materials, speaking opportunities, media outreach and more - plus the benefits of participating in a fun and meaningful community event!
