Greenlink services the greater Rockford area, northern Illinois, and southern Wisconsin. We offer individually tailored net zero solutions with our highly qualified solar installation experts and through local partnerships with electrical contractors and roofing professionals.
Greenlink will even provide you a solar estimate for your home or business at no charge.
If you are comfortable in your home and just want to add solar to save money and increase your energy independence, Greenlink can help with that.
Alternatively, if you have additional concerns about the efficiency or comfortability of your home, our experience as a whole-home building efficiency organization makes us uniquely suited to provide balanced and cost-effective recommendations that will make the biggest impact on your concerns. These recommendations stem from our no-obligation energy audit of your home, which provides solutions based on science, rather than guess-work.
Greenlink's pitch is simple: we will give you honest and practical answers, with the highest quality outcome for your concerns as our benchmark, and we will do it with a friendly and humble approach that we would want for our own families.
