Excellent service. Gave me lots of different options and allowed me to decide what is best for me. Never high pressure. After it was installed they kept me updated on Edison. Now my bill is less than $5 a month. It cut my energy bill in half.
We elected to install a system on PowerChoice through Apple Valley Choice Energy… Excellent experience from contract to PTO! System works as promised and my wife and I are so pleased with our ability to reduce our utility bill while improving our resiliency and ability to help our community out when our batteries are used as a virtual power plant…did I mention we lowered our electricity bill and have the bonus of receiving payment for participating in the virtual power plant program! Win-win! Thank you Option One!

Lower bill + added resiliency + virtual power plant participation is a strong “win-win” equation. Thank you for choosing Option One Solar and for sharing that your experience from contract to PTO was excellent — we’re glad the system is working as promised for you and your wife.
A family member recommended Option One Solar after having a big job done by them and being completely satisfied. When I saw their work, I was impressed, and after doing my own research, I felt good about their reputation. I wanted to work with a local company and avoid the door-to-door sales approach, and I’m glad I chose them. They installed my solar panels and a Tesla Powerwall, and the whole process was fast and efficient. They were easy to reach, did an awesome job, and I couldn’t be happier!

Great experience with Option One Solar. They did quality work, completed everything on time, and the pricing was fair. The entire process went smoothly, and I would definitely recommend them to anyone looking for solar.

Thank you for the 5-star review. Fair pricing, on-time work, and a smooth process are exactly what we aim for — straightforward solar without the pressure. We appreciate your recommendation and are glad you had a great experience with Option One Solar.
After installing the batteries they covered on how to use the Tesla app. We really appreciate that.

Thank you for sharing your experience! We’re so glad to hear your system design has been meeting your annual energy needs and that you’ve been happy with the service from Option One Solar. We appreciate your trust and your 5-star review.
Option One Solar - I highly recommend them from design to install home to batteries to follow up and Emp Protection. They were excellent and they are excellent and anytime anything comes up. They follow through and take care of any concerns I have had. I don’t do reviews very often, but Option one Solar is one of my favorite companies to work with. Excellent products and service all working great three years later and still Solar is covering my electrical use.
I recommend them without hesitation.

We’re thrilled to hear your system is still performing well and covering your electrical use, and that our team has continued to follow through whenever you’ve needed us.

Option one Solar was a pleasure to work with. Trever did an amazing job installing a new inverter and panel. Natasha was quick at quoting the job and making contact seamless. I would highly recommend this company. Satisfied customer.

Thank you so much, Lisa! We really appreciate the kind words and are glad we were able to get your inverter replaced, your panel installed, and your system fully up and running again. It was a pleasure working with you, and we’re happy to hear that Trever and Natasha made the process smooth. Thank you again for trusting Option One Solar!
I recently had a 31-panel solar system installed along with two EcoFlow battery backup units and a main service panel upgrade. The entire process was smooth from start to finish. The team was professional, knowledgeable, and kept me informed throughout the project.
One thing I really appreciated was that they handled everything, including the electrical work, permitting, installation, and final inspections. The installation looks great, and the battery backup system gives me peace of mind knowing I have power during outages.
Before solar, my electric bill was regularly over $600 per month. Since the installation, my bill has essentially dropped to zero. The batteries have also been a game changer. When the power goes out in my neighborhood, I honestly don't even notice because the backup system takes over seamlessly.
The system has performed exactly as expected, and I couldn't be happier with the results. If you're considering solar, battery storage, or electrical upgrades, I highly recommend Option One Solar. Great company, quality workmanship, and excellent customer service.
