TESTIMONIAL

Steve, St Regis Falls, NY says:

Eric exceeded my expectations by guiding me to the correct mounting brackets. He went out of his way by even going and measuring the parts in question to make sure they fit my non standard mount rails. The only way this could have been a better transaction is if Eric came over and helped with the install. Thanks!

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!
