Great Experience with Solar Optimum!

I am so happy to have chosen Solar Optimum to work with to go green. Solar Optimum was so easy to work with. Thanks to EnergySage, I was able to find the very BEST prices with Solar Optimum. It was the easiest way to shop for solar.

Top tier communication!

The rep who guided me through the process always responded to my questions quickly. Overall solar optimum was a pleasure to work with and they moved through each step quickly. I would hire them again for future solar projects and I recommend to anyone considering.

Excellent Service Throughout Solar System Installation Process

Professional team that provided excellent service throughout the solar system installation process, including a sense of urgency to meet the CA NEM 2.0 deadline. A special thank you to Will P for his assistance and guidance throughout the process.

Very Happy

Very happy with the service I received here. Kevin Taing was my consultant and he was thorough, took time to explain answers to my questions, walked me through the process and had plans drawn up within a day. He also helped me with an aggregator permit because I have an ADU. From initial contact in late Jan/early Feb to installation and full operation, the timeline was 2 months. The contractor was timely, professional, and installed on time. The only thing I wish had been done better was taking the time to call and walk me through how the App works, how to trouble shoot my system etc. They send you an email, but it would have been nice to learn on site since they were already here. All in all, 5 stars. I contracted Feb and I am fully solar as of March 26th!

Great Service and product

It's common to hear horror customer service stories when it comes to solar sales. Luckily, my sales consultant was Argeesht and he was very responsive. There were points in the project where the communication extended past just the sales consultant. In times where I was stuck waiting for a response, Argeesht helped push it through. As for the installation, it went fine. The installers completed their installation in a day and it passed inspection without a hitch. I've gone through the rainy season and have not seen a leak. I'm a happy customer.

Fantastic Customer Service

Solar Optimum provided the best in class installation experience. Tesla was about 2K cheaper than Solar, but I opted to go with Solar purely because of the customer service that they provide. I was not disappointed. The hand over from Initial Inquiry to Sales to installation and post installation was seamless. They managed to even get all possible rebates that I am eligible for. Overall I strongly recommend this company to others
