Amazing Solar Installer!!!

I spent many months researching solar before finally committing to my install with OnSite. After having gotten quotes from almost a dozen different companies - from small local ones, to regional ones, to national ones - I can say that OnSite was the most knowledgeable, honest, and offered, hands-down, the most competitive prices. In an industry that abounds in shady sales tactics and pushy salesmen willing to tell you flat out lies to get you to sign with them, OnSite is a beacon of bright shining light in the darkness that is the Residential Solar Installation Industry. I came into this having done a ton of research on technical specs of panels and inverters, system design and optimization, building and fire codes, rebates and incentives, etc. Ryon - the company owner - and his team were able to take all that and work with me to fine tune my system design and dial it in perfectly. The whole process, from my initial phone discussions with them, to the site survey, to the install and to passing all inspections and getting permission to operate from the utility, was super smooth. Ryon kept me informed every step of the way and was always available and very helpful with any questions I had. Even after the system was up and running, when I had an issue with the Enlighten app, Ryon helped me sort it out quickly by calling the company. The install itself was very professionally done. Everyone in the crew was very respectful and did quality work and did it efficiently. You know the saying: Quality, speed or price - choose any two. Well it doesn't apply to OnSite. They somehow nailed all three parts of the Project Management Triangle. Can't say enough great things about this company. Would recommend them in a heartbeat to anyone interested in going solar.

Love our solar panels

Just wanted to drop a quick line to say thanks to Ryon and his guys for the awesome job they did installing our solar panels. Ryon was very professional and always willing to answer any crazy questions. He has a wonderful team and I have recommended him to many friends and family. Have I mentioned our ORU bill has been greatly reduced. Yay savings
