What partners value most.
★★★★★
“I work for RevoluSun Idaho and we use GreatSun for our new build designs on our software. He is very quick and accurate and always accommodating to modifications and requests as the builds evolve. We would recommend his services to any other solar or energy contractor!

★★★★★
“Very knowledgeable and offered proactive responses – he suggested solutions that we had not thought of previously and acted as a strategic partner as opposed to a vendor. We’re looking forward to continuing our relationship with GreatSun Consulting”

“GreatSun handles modeling all new construction designs in Aurora for our team and does an excellent design in an extremely timely fashion! Not only is he exceptionally capable at reviewing new construction plan sets and modeling them with accuracy, but he is also amazing at being resourceful and finding solutions when builders send plan sets with missing information. On top of all of that, John is a solar industry guru with expertise in CRMs, marketing, solar sales and design, working with new construction, Tesla Solar Roof and more. I would highly recommend him to any business.”
