CUSTOMER STORY

A Green Dream in Action

Roland Goulette has been planning for his renewable energy system since the 1980s. In an effort to save energy, Roland started recycling and purchased florescent light bulbs. This passion for green led him to where he is now. He owns a 24-panel PV and solar hot-water system. Roland and his family are a perfect example of hard work and planning paying off!
