The National Solar Tour is the largest grassroots solar, renewable energy, and sustainable living event in the nation. A collection of solar open houses and local solar tours around the country, the Tour occurs October 6 & 7 and the surrounding weekends. The Tour brings together solar supporters, home and business owners, and community members together to celebrate and help grow solar in their communities. Solar homes, businesses, non-profit organizations, municipal buildings, places of worship, schools, and community solar gardens are all invited to host open houses on the National Solar Tour.
