OneGrid - Recommended

We received 5 quotes through EnergySage, and we chose OneGrid primarily because they were the only company that actually read our project spec and took our HOA constraints into account. We are very pleased with the outcome of the project. Everything moved quickly, we were kept informed throughout the process, and the installation team was professional, polite and fun to work with. Recommended!

The search is over: OneGrid Energy is the solar company you want on your side

⚠️ Long review, but absolutely worth reading if you’re considering solar. ⚠️ OneGrid Energy isn’t just another solar company, they are in a league of their own. From the moment they stepped on my property, everything moved at lightning speed. Site visit, design, approvals, it all happened in what felt like overnight. One week later, my system was already being installed. That kind of precision and efficiency is almost unheard of in this industry. But speed is only part of the story. The real magic of OneGrid is their culture. This company feels like family. They treat you as a partner, not a number. You can walk up to their founder and have a genuine, down-to-earth conversation, no sales pitch, no ego, just authenticity. Every single staff member I met radiated passion for what they do. I watched their crews working tirelessly in 90-degree heat, still smiling, still proud of the work they were delivering. That doesn’t happen by accident, that’s a culture built from the top and lived by everyone at OneGrid. My installation turned out beautiful. One of the co-founders, Dexter, personally took the time to understand my vision. He didn’t push what was easiest for the company, he worked with me to create exactly what I wanted. I had gathered multiple quotes, held conversations with four other companies, and even had an additional site visit. No one else came close to the care, detail, and trust I felt with OneGrid. They aren’t just installing solar, they’re bringing your vision to life and making you feel like you’re part of something bigger: the OneGrid family. Even when I asked additional questions or requested a small adjustment to my systems finish once installed you are programmed as a consumer to assume you are going to be ghosted or get a negative response... not at OneGrid! When you spend money on a project of this scale, you want to walk away feeling you made the right choice. With OneGrid, I didn’t just feel “good” about my decision—I felt great. Their communication was flawless, their staff was professional and upbeat, and the results speak for themselves. OneGrid, please don’t ever lose what makes you special. Your honesty, your energy, your people, and your commitment are rare in today’s world. That’s why I wrote this review. ⭐ Five stars, without hesitation. If you’re considering solar, stop searching. OneGrid Energy is the company you’ve been looking for. ⭐

Satisfied Customer

Service was great and job was done with great pride and not rushed.

Seamless Experience!

Dexter was honest and transparent about what would work best for our home – not salesy like other solar companies. The OneGrid installation team and office staff are total pros. Each stage of the process was clearly explained, and they delivered on time with no surprises. I would recommend OneGrid to anyone looking to move to solar.

Solar Done Right

Just a fantastic experience. Looks amazing. Talk of my neighborhood. People do not even know I have solar panels on my roof.

Just a short note to provide positive commentary on the overall experience from the first introduction to the quotation process with extensive Q&A's on the costs and installation, which in the end exceeded my expectations and would not hesistate the referral and endorsement for solar investments with One Grid Integration.
