Jesse and his team did an excellent job on our new roof and solar package! Work was professional and completed on time and they’re pricing was excellent. I highly recommend Underline Energy Concept. -Ryan

We had our solar installed a few months ago by Underline. I did a lot of research prior to choosing them. They do not sub out the installation like most of the solar companies I spoke with. They had the best pricing out of all of the companies and they were honest. Not once did they try to sell me any additional services/options that I didn’t need. Jesse, David and the Underline Ener team did an amazing job. Oh and a special shout out to Dylan!!! Dylan was on site from start to finish! He cleaned up after himself and was on time every day. Thanks guys!

True professionals, from initial project consultation to project completion. On time and under budget. Unlike other contractors, Underline Energy Concepts steps above the usual noise, with their highly experienced, professional, and dedicated sales and installation specialists, as well as by a cheerful and professional office staff.
After several frustrating attempts to get a contractor to review my project proposal, I was contacted by Mr. Luis Mayoral, who inquired about the status of my efforts. Mr. Mayoral followed our phone interview with a personal visit to my residence. He inspected my project and provided recommendations for tailoring the work to my needs. Additionally, he provided more information which gave me a range of choices as to the best product for my budget.
Mr. Mayoral provided a structure of costs with attention to my status as a Senior Citizen...

Micheal, Jesse the whole team is 10/10. I needed some extra roof tiles a year later and they helped me out! Phenomenal service.

Michael from Underline Energy Concepts is the best. If I could rate him 5+stars I would. He provides outstanding customer service and support; he is professional in all aspects of his job and he excels in follow through and keeping me informed.

Underline is a good, professional Solar/roofing company that knows and functions in the industry well. They use modern tools to make the process easier and user friendly like drone images and computer models for pre-visualization. I was in the initial stages and setup with them for a long time because of the City of Colton but they explained everything that was going on and held our hand through the process. When it finally came time to do the roof and install the panels and it was done quickly and efficiently.
