POWERFULLY GREEN owners Rebecca Lundberg and Dan Williams are both NABCEP Certified Professional Solar Installers, and NABCEP Certified in PV Technical Sales. NABCEP (North American Board of Certified Energy Practicioners) is the highest level of certification available in the solar industry.

Rebecca Lundberg is also a licensed Minnesota Residential Building Contractor, and International Ground Source Heat Pump certified. Dan Williams has over 18 years of experience in the construction industry. We are active in our local community, giving lots of free presentations, serving as volunteers on the Board of Directors for the Minnesota Renewable Energy Society and Minnesota Solar Energy Industries Association, and working with the Minnesota Pollution Control Agency on the award-winning Eco Experience exhibit at the Minnesota State Fair.

When you call POWERFULLY GREEN you won’t get a high-pressure sales pitch. In fact, you won’t ever meet a sales person -- what you’ll find is that we’re enthusiastic about what we do, and we’re educators. We take the time to answer your questions, give you system options, show you local examples of our work, and offer local references. Our solar site assessment provides you with a guaranteed maximum price; we don’t like being up-charged because the first bid wasn’t all-inclusive, so we won’t ever do that to you.

You will find that a POWERFULLY GREEN solar energy installation means that the same knowledgeable owners that helped you decide on your solar energy system are also the people doing the work on your property. Every member of our installation crew is clean, professional, and courteous. We work carefully to make sure that each attachment point has multiple levels of leak protection, and that each solar module is installed to manufacturer’s specifications to insure a long, productive life. Helping you become energy independent is a celebration, and we take pride in what we do.

POWERFULLY GREEN has been installing solar in Minnesota and Wisconsin since 2007. Our home-office is powered by the sun, and we’d love to show it to you in person! We currently have five different solar energy systems: three examples of photovoltaic systems, a solar domestic hot water system, and a solar day-light. We also have a plug-in electric vehicle that charges with our solar power. Please visit the 'Our Sustainability' page to learn more about our home-office. The future is now! Contact us and let us help you with your next solar project.
