Thinking about adding solar? Talk to three of the exhibitors at the April 22 Wooster Scarlet, Gray and Green Fair: Ashland’s Hyperion Energy Solutions, which offers solar power consultation and management; Sugarcreek’s Paradise Energy Solutions, which installs solar in homes and businesses; and Cleveland’s Carbon Vision, which has designed, installed and managed solar systems at such places as Hiram College and the College of Wooster. Solar power, of course, is renewable and helps cut greenhouse gas emissions. Also of note: Carbon Vision’s solar project manager is giving the fair’s keynote talk.
