“We were paying thousands of dollars per year on a design tool that was way slower and less accurate.  Now all of our team use OpenSolar for designs, proposals and managing our installs, for FREE - it's also really cool that we can brand the whole experience for our customers."

‘’Time kills deals and processing finance applications manually is brutal on sales momentum. Since embedding our preferred finance products directly into our OpenSolar proposals, we've probably shaved 30 minutes off of every financed project and our sales reps and customers love how easy it is to apply and sign right there on the spot.’’
