I recently worked with HCI Solar for a home solar installation and couldn't be happier. Anthony was always quick to respond and explained everything clearly. They got our permits in weeks and installed the system in just one day. The quality of the work was excellent.

What sets HCI Solar apart is their great customer service. Anthony kept us informed and addressed all our questions. Since the installation, our energy bills have dropped significantly. I highly recommend HCI Solar for their excellent products and service.

We had a great experience working with Anthony on optimizing the amount of both solar panels for daily use and batteries in case of a blackout. He was very responsive to our follow-up questions via text, and we were able to call him when needed.
HCI Solar provided turn-key service, so they assisted with permits and plans. We saved so much time and hassle since they dealt with the city on our behalf. For solar and battery, it took 2 days to complete and the installation team was on-time in the morning. Overall, we are happy with HCI Solar’s great customer service and installation.

Anthony, Jose and the team at HCI solar was amazing, Anthony was extremely knowledgeable and was very detailed to help us get the best system for our needs. They did everything from helping get permits to the full installation. The crew installed everything in 1 day and left our home even cleaner than before they came. I loved that even after the sale he checked up on us to make sure everything was still good a few days later. It shows they really care We are so happy we will have them do our vacation home next!

I had such a great experience with HCI Solar. From the very beginning, their team made everything super easy. They took the time to walk me through all the solar options, patiently answered my million questions, and genuinely wanted to help me find the best fit.

The installation process was smooth — they arrived when they said they would, got everything set up quickly, and didn’t leave a mess behind. The panels look great, and I can already see a big drop in my electricity bills. They even showed me how to track my energy usage, which is pretty cool.

If you’re thinking about going solar, I highly recommend HCI Solar. They made the whole process easy, and I felt like I was in good hands from start to finish. Great team, awesome service — couldn’t be happier!
