What our Pros have to say
Casey Coffman | Laibach Solar| California, USA
“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."
