I was at first confused about what Energy Sage was. Once I realized it was kind of like a broker, matching customers with providers, I expected it to be an automated, mechanical formula, and I was skeptical of getting much value from it. Energy Sage far exceeded my admittedly low expectations. They were personal, getting on the phone with me frequently and showing interest in my individual project. They were professional, responding quickly with deep knowledge of the business. Most importantly, they were highly effective. The vetting they do before admitting a company to their listing is thorough and valuable. They way they line up companies for direct side-by-side comparisons is fantastic. The guidance they provide through a confusing process is invaluable. The only negative, if you can call it that, is that they are better suited for customers who have already decided they are definitely going solar. The vetting process they do with customers might not be worth it, if you're really on the fence still. But, if you've decided you want solar, START with Energy Sage. It's like having a professional consultant for free.
