Shining Bright with Solar Optimum! ☀️ 10/10 Highly Recommend!

Long story short, my builder-installed solar system was just too small. Adding additional panels on top of my townhome was a big decision, and I'm thrilled I partnered with Solar Optimum! From the initial quote to the final activation with SDG&E, their team was professional, efficient, and incredibly helpful. Here's why I loved working with them: • Competitive Pricing: Their quote was competitive without sacrificing quality. We went with Panasonic panels and Enphase microinverters, the two bests in the industry! • Seamless Process: Every step, from surveying and design to installation and activation, was handled smoothly and efficiently. • Top-Notch Service: The team was knowledgeable, responsive, and always happy to answer my questions. They truly went above and beyond to ensure my satisfaction. • Speedy Activation: My system was activated with SDG&E much faster than anticipated, thanks to their proactive approach. • Zero Issues: The entire process was smooth and hassle-free. Overall, I can't recommend Solar Optimum enough! They made going solar a stress-free and positive experience. If you're considering solar in Southern California, look no further! They're the absolute best! P.S. Minus the cloudy weather in San Diego, I'm generating plenty of my own clean energy and finally saving money on my electric bill. Couldn't be happier! ⚡

Very Professional Installer

I wanted to squeeze into NEM2.0. And Solar Optimum helped me achieve that. The overall process took a little longer than I expected, also because I have an ADU that needed to be finished before the installation. The installation itself took one day, the guys were very professional. I can understand that they can be a little slow in responsiveness due to high volume of NEM2.0. Overall, highly recommend!

Best company!

Solar Optimum was terrific from start to finish. All the people we dealt with were super helpful starting with Kevin Tiang and everyone in all of the other departments. The permits and system installation went so much faster than I expected. The panels look fabulous and work great! I am very pleased that we went with Solar Optimum. After researching so many other companies I am confident we ended up with the best!

Positive experience

My sales representative, Eddie Rodriguez, as well as my local contact, Salko, both proved to be great resources and timely to respond. Positive experience the entire time. Can’t wait to be able to turn on the system.
