Solar Optimum Equipment and Monitoring

Solar Optimum offers some of the best solar equipment currently available on the market. As an elite and premium partner, the company installs only tier 1 panels manufactured by QCells;inverters and battery storage produced by Enphase and Tesla Energy and mounting and racking from Unirac; and battery storage from Tesla.

Additionally, the company delivers integrated, cell-based monitoring that is more reliable than WiFi to go along with its solar energy systems, which allows customers to see how much their system is generating.

Solar Optimum is also a GAF President’s Club and Master Elite Contractor as well as a CertainTeed Elite Shingle Master for all residential roofing needs.

Solar Optimum Warranties

Solar Optimum provides customers with industry-leading warranties to cover different components of its solar energy systems. The company has a 25-year panel and inverter warranty, 25-year racking system warranty, 25-year roof warranty, 25-year workmanship warranty, and a 25-year performance guarantee.

Additionally, Solar Optimum allows homeowners to transfer all warranties. Usually, solar companies only provide warranty coverage to the original purchaser of the solar system. This means that if you sell your home, the new homeowner does not enjoy the solar system warranty coverage. With Solar Optimum, if the original owner sells the home with a Solar Optimum solar system installed, the warranty transfers to the new homeowners.

Solar Optimum Frequently Asked Questions

How does going solar with Solar Optimum work?

The first important step is setting up a consultation with one of our Energy Consultants. We are currently offering phone and video consultations. It's vital that we understand the customer's energy goals and current (and future) electricity needs in order for us to create a customized solar system and provide a quote.

How much does a solar energy system cost from Solar Optimum?

There is no one-size-fits-all answer for this because the cost of the system depends on many variables like electrical usage, energy goals, product selection, utility company, etc.

What solar panels does Solar Optimum use in its installations?

Solar Optimum only installs tier-one, industry-leading panels, inverters, racking, battery storage, and solar products from the best in the industry that have the best warranty. This includes American-Made Mission Solar, Enphase, Tesla Energy, Unirac, GAF, and CertainTeed to name a few.

How long will it take before the solar panels are installed?

In the best case scenario, a solar system can be installed and turned on in around 90 days. However, many variables are involved in getting the solar system installed and turned on. Delays in turning the system on may depend on the utility company. Some jurisdictions take longer than others.

Does Solar Optimum require a contract?

Yes.

Do the solar panels work when there is a power outage?

Solar panels do not work if there is a power outage. The solution for this is the home battery back-up that we offer from Tesla Powerwall. If there is a power outage, energy is pulled from the battery. Solar Optimum currently offers Tesla Powerwall and Enphase IQ battery options.

Outstanding Experience with Solar Optimum Solar Optimum exceeded my expectations from start to finish. Their team was professional, knowledgeable, and genuinely committed to helping me find the best solar solution for my needs. They took the time to explain every step of the process clearly, answered all my questions patiently, and never made me feel rushed or pressured. The installation was smooth, efficient, and well-organized. The crew arrived on time, worked cleanly, and treated my property with respect. Everything was completed exactly as promised, and the system looks great and performs flawlessly. What really sets Solar Optimum apart is their customer service. Communication was excellent throughout the entire process, and even after installation they remained responsive and helpful. It’s clear they take pride in their work and care about long-term customer satisfaction, not just making a sale. If you’re considering going solar, I highly recommend Solar Optimum. They deliver quality, transparency, and peace of mind—everything you want when making an important investment like this.

Despite an ongoing +4 month long complaint with Freedom Forever, they at last sent Derrick Corona and his college to reinstall our 14" twirly-bird roof vent taken down, on on a whim, by irresponsible subcontractors on 09/06/25. Freedom Forever dragged their feet for almost 4 months trying to get the original subcontractors to replace the whirly-bird vent, without success. Today, 01/10/26, Derrick's team got it done, with our high praises of 5 stars! Praises go to a few true supervisors who really cared, and escalated this project onto completion! To those supervisors, we give our heartfelt hank you, sincerely!! PS To a few unkind supervisors set up 2 appointments with the homeowner (on 12/29/25 and 01/10/26) to arrive between 7AM-8AM and in both cases, the workers didn't arrive until 1 PM and 10 AM respectively. That sort of treatment to this homeowner is: reprehensible, seemingly on purpose, and outright mean! This homeowner personally feels that some of Freedom Forever's supervisors inflicted "bad manners" and harmed the face and image of Freedom Forever!! To those supervisors, I add, shame on you! You've forever tarnished the image of Freedom Forever in this customer's eyes! I sign my name as a customer and homeowner, Carol Richards

Update: Solar Optimum has since satisfactorily resolved this issue and refunded my full deposit. I appreciate that they ultimately did the right thing and brought this matter to a fair resolution. ———————- I chose Solar Optimum because their initial proposal guaranteed that the solar system they designed would generate enough energy to power my home. I specifically asked if the system would produce the full 11 kilowatts they quoted, and I was told it was guaranteed. Based on that assurance, I paid a $1,000 deposit. After taking the deposit, Solar Optimum revised the design from 26 panels to only six because of roof space for panels. The new system would produce only a fraction of what was originally promised, which made the project financially unreasonable for me to continue. I requested a refund of my deposit, but instead of honoring the guarantee, Solar Optimum initially refused, then said they would only return half of my deposit. I have repeatedly reached out, and I still have not received any refund or any meaningful follow up. My experience has been frustrating and disappointing. I hope Solar Optimum does the right thing and resolves this, but until that happens, I cannot recommend them.
