Payment options

Although Solar Optimum may not cover the entire United States, there still an outstanding solar company to opt-in for if you live within California. Here are the payment options that they offer their customers:

  • Finance – This allows you to own the system but pay in installments.
  • Purchase – Let’s you purchase the system outright, meaning you don’t owe the company any additional money.

What we look out for in a solar company is a simple customer transaction from the initial quote to the installation process. Let me tell you, Solar Optimum has done a superb job of this. This is how their installation timeline looks like:

  • Consultation – First, you’ll be required to opt-in for Solar Optimum’s free at-home consultation service. During this period, they’re assessing whether your property is suitable for solar power.
  • Conversation – Once they’ve evaluated your home and have agreed that your property is sustainable for solar energy, you can now ask questions about any queries you may have.

  • Design – During the payment process, you’ll be provided a quote based on your requirements, and here is where they finalize your design options.
  • Installation – Now your design has been approved, and you’ve gained the appropriate permits. Solar Optimum will then begin the installation process, which can take up to six or eight weeks, depending on the size of the project.

Solar Optimum sticks out from the top solar companies in the United States due to their warranty. This is because they offer a flat 25-year no-questions-asked warranty on panels and inverts, racking systems, roof, workmanship, product guarantee. Additionally, if you decide to move from the property, the new homeowners will be covered with a 25-year warranty transfer.

Battery storage

Solar energy is great but storing it for a rainy day to ensure you have a power supply no matter the situation is even better. When it comes to battery storage, Solar Optimum offers three types of systems. Within this selection, you’ll find home emphasize batteries, Tesla Powerwall’s (approved installer), and also larger storage batteries for businesses.

Each battery storage system is superb, is tailored to meet specific requirements, and can offer all types of customers a chance to store solar energy.
