Solar Planet Group

About the Company

Solar Planet was founded in Dubuque, Iowa by Lisa Mueller, Tim Mueller and David Mueller. They realized that with both endlessly rising fuel prices and growing pressure to find an environmentally friendly means of obtaining clean electricity, the natural cure is for everybody to generate their own power! Most people either think solar power is beyond their reach because of its price or they lack the expertise to get a system installed. Solar Planet is here to make going green easy!

Lisa Mueller


With over a decade of experience in managing convenience stores across Dubuque, Lisa has consistently demonstrated the highest qualities of reliability, compassion, and the necessity of precision management. When a major convenience store chain acquired her stores in 2007, Lisa played an important role in the successful integration into the chain's empire of 70 locations.

Tim Mueller


Life's pursuits and business performance have confirmed Tim's talent and capability to direct a renewable solar energy organization and impact electrical power worldwide. He recognized early in life an aptitude for mechanical and electrical projects. From his college days of 1980 through 1986, he has worked key technical positions for several companies. From a technical service representative of ATM's with Dubuque Bank & Trust, to the head of the technical maintenance department at Embassy Covenant Property Management of New Orleans.

In 1986, Tim launched Tri-State Telephone Supply, whose mission is: To install telecommunication equipment and computer backbone network systems. For 23 years he grew his territory to cover a 100 mile radius of Dubuque, Iowa. Relationships expanded his business model to include over 750 commercial accounts and thousands of residential customers. During this time, Tim has always wanted to do something bigger than himself that would make a difference to the world.

Recently, Tim has taken a profound interest in solar energy, and has since pursued his North American Board of Certified Energy Practitioner (NABCEP) certification.
