What Services Does Solar Optimum Provide?

Solar Optimum helps customers reach their solar energy goals through residential and commercial solar installation and solar battery storage solutions.

Solar Panel Installation

Solar Optimum manages residential installations from start to finish, beginning with an at-home consultation.

• Consultation—Solar Optimum provides a free at-home consultation, confirming your home’s ability to support a solar system. Factors like household electrical demand and the size and shape of your roof affect your home’s compatibility with a system.
• Conversation—After evaluating your home, Solar Optimum’s local experts will answer any questions you have regarding solar panels and your specific installation plan.
• Financing—Solar Optimum will walk you through their financing options and teach you about available solar incentives.
• Design—Based on your home’s infrastructure and energy consumption, Solar Optimum designs a solar energy system to fit your needs.
• Installation—Once Solar Optimum completes the necessary paperwork, their installation specialists will install your personalized solar panel system. For most projects, the entire process takes six to eight weeks.

Solar Optimum’s commercial counterpart follows a process similar to residential installation, with the company designing, building, and managing the entire project. While a residential solar system is installed on a customer’s roof, Solar Optimum provides its commercial customers with different installation methods like ground-mount solar and carport solar.

Solar Battery Installation

If your solar panels generate more electricity than your home requires, installing a solar battery allows you to store the excess power for future use at night or during a power outage. For residential customers, Solar Optimum offers the Tesla Powerwall solar battery, which holds up to 13.5 kilowatt-hours (kWh) and comes with a 10-year warranty. The amount you will spend on a Powerwall depends on your location and how many you need, but one typically costs around $12,000.

What Do Customers Say About Solar Optimum?

Solar Optimum is accredited by the BBB and holds an A+ rating from the company. Here’s a sample of Solar Optimum customer reviews:

“We contacted Solar Optimum for quote after having already talked to several other installers and Solar Optimum is clearly a step above the rest. It was a no-brainer for us to sign with them for our solar system. We had a 6kW Panasonic system installed on our home to save money because we are a family of five and we use a lot of electricity. After we had our system installed, we actually noticed a huge difference almost right away.“ — Dimitry S.

“Overall great company to deal with. Very prompt with scheduling and great job on installation. Best part is, when you call, you actually get to talk to a person! It seems like the company is smaller in regard to other competitors, but is nice because requests and questions do not get lost in the abyss!“ — Rory T.

“I have made numerous attempts to get this company to do what they said they would do. I’ve been lied to, calls not returned. They have a referral program that they refuse to honor. Very poor customer service, I’m sorry I used this company. Would never recommend them.” — Marquita R.

“Please do not go with Solar Optimum. They gave me a low bid on Solar Power on our roof. My wife and I decided we were going to go with them. I told him 100 times that I have a clay roof. He constantly assured me that was included in the bid. Before finalizing, Ryan calls me and says their contractor needs to go out there and what they need to inspect and it will be an additional amount for each tile that needs to be replaced. What a bait and switch. Send us a low ball bid and then changes it later. Avoid at all costs. There are so many other reputable solar companies out there.“ — Ronald B.
