Amicus Solar Cooperative was founded in the fall of 2011. A small group of friendly solar installation companies decided it was time to form a national organization where independent businesses could support each other by sharing best practices and pooling their buying power. Amicus is a purchasing cooperative that is jointly owned and democratically managed by our member companies. We are 31 members, with 43 office locations in 22 states. Member companies are passing their enhanced purchasing power along to customers by offering best solar pricing on high-quality solar electric system installations. Third Sun Solar is a founding member.
