Solar Optimum Solar Power Services

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.

Cost of System Installation from Solar Optimum

To receive a quote from Solar Optimum, customers must provide their address and most recent utility bill. Using this information, Solar Optimum can create a preliminary proposal that’s shared with you during your at-home consultation.

With regards to the installation, the crew [was] respectful and efficient and didn’t leave a trace behind. We are extremely satisfied.“ — Angel H.
