The Good

  • High-Quality Equipment and Monitoring
  • Exceptional Warranties
  • Several Flexible Payment Options
  • Premium EPC Company
  • Certified Battery Installer for Tesla and Enphase
  • 15+ Years of Experience
  • Positive Client Reviews

High-Quality 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 Panasonic, Solar4America and REC Solar; inverters and battery storage produced by Enphase; mounting and racking from Unirac; and battery storage from Tesla.

Additionally, the company delivers integrated, cell-based monitoring that's 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 Master Elite Contractor and CertainTeed Elite Shingle Master for all residential roofing needs.

Exceptional Warranties

Solar Optimum provides customers with unmatched warranties to cover different components of their solar energy system. 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 production guarantee. 

Additionally, Solar Optimum allows homeowners to transfer any and all of its warranties. Usually, solar companies only give the warranty to the original purchaser of the solar system. Meaning, if you sell your home, the new homeowner does not enjoy the solar system warranty coverage. Solar Optimum changes that. If the original owner sells the home with a Solar Optimum solar system installed, the warranty transfers to the new homeowners.

Several Flexible Payment Options

Solar Optimum offers a variety of ways for customers to pay for their solar energy system, including outright purchase, and loan. With so many options available, customers have the ability to select a payment method that fits well with their needs and budget.

Premium EPC Company

Solar Optimum is a Premium EPC company, which means they will handle everything from A to Z: engineering, procurement, and construction. This is a good indication that customers will receive a high-quality installation with Solar Optimum.

In fact, from its fleet of thousands of solar system installations over the last 15 years, Solar Optimum routinely engineers and produces systems that yield an average of 108 percent more productivity than is guaranteed by component manufacturers.

Certified Battery Installer for Tesla and Enphase

Solar Optimum offers the Tesla Powerwall 2.0 and the Enphase IQ Home battery. They are among a select group of nationwide solar energy providers chosen to be a Tesla Certified Battery Installer and Enphase Platinum installer.

15+ Years of Experience

Solar Optimum has over 15 years of solar, battery, and roofing experience. An energy provider's longevity is one of the most important qualities for clients. If clients are in need of any other services, maintenance requests, or warranty promises, the company must be in business. Not only does the company’s time in business promise further service, but also the company is well experienced. Solar Optimum has impressive industry and operational experience. 

Positive Client Reviews

The majority of Solar Optimum's reviews on BestCompany show that consumers are happy with the company and its services. Customers praise the company for its professionalism, overall customer service, and its quality solar systems. Many consumers chose Solar Optimum for the multiple 25-year warranties and are thrilled to have such extensive coverage.

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. For convenience during the COVID-19 pandemic 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 Panasonic, REC, Enphase, Unirac, GAF and Tesla Energy 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.

Rob Motal Pleasanton, CA

Solar Optimum made purchasing a solar system an absolute pleasure. First their salesman was patient, courteous and very knowledgeable. Price was better than offered by others. They offered panels (Panasonic) as good as any other and which has a factory in the US. We needed it installed before the end of year to get the favorable tax credit and they were the only company who were sure they could. There installers were skilled and efficient. We discussed options on location of the electrical boxes and where the lines would be run. They worked into the late hours on the final day to finish the job before the expected rains the following day. There were minor issues which they promptly corrected. Our system is up and running smoothly. This contrasts strongly with some of our friends' experiences who also had solar installed during the same time. One installer failed to secure permits which resulted in delayed startup and savings. Another had issues with installation on a tile roof and had some aesthetically displeasing features. And their systems cost more and produced less.

Adding Solar panels was completely foreign to me. The team at Solar Optimum was fantastic. They communicated every step of the way and were extremely easy to get a hold of if I had questions. There was virtually no work on my part other than getting HOA approve and signing a few documents. Solar Optimum managed every other aspect of the project and communication with the city and SCE. They are fast too, I’m already generating my own power. AND to top it off their quote and financing was HALF their competition. I’d highly recommend and already have to friends and family.

Solar was very pleasant to work with; the technician took the time to explain how everything worked while the installation was being done. Solar Optimum had to do things in steps because they had to wait on PGE for approval, but once things were approved, it took no time to get the solar up and running. I had a little issue with the installation, and Solar fixed it the following week. I am happy to recommend Solar Optimum to anyone that needs Solar.

Recently had 2 Tesla batteries installed to compliment existing solar system. The Tesla system design and installation was superb. Very clean and efficient. The technicians were very capable and polite. Everyone at Solar Optimum was cordial and accommodating. Just be aware that the timeline on projects as this is long because of all the various parties involved — approvals, licensing, commissioning, etc. Solar Optimum does all it can to expedite, but it takes time! In summary, I am very happy that I selected Solar Optimum to do my installation. They know how to navigate the bureaucracies involved and communicate progress. Jim W

I did a lot of research before I decided to select Solar Optimum, I would say that they were not the cheapest but they have a competitive price. I decided to go with this company because of the 5 star rating reviews and being awarded by Panasonic as installer of the year. I was not disappointed and they fulfilled their promise in installing my solar in less than the time frame they gave me, thank you William and Francisco. Their Installers were very professional and they even help me to replaced a bad breakers, thank you Raffi. Their customer service were awesome and always there to answers any questions, calls and emails. I am now enjoying the benefits of solar power, I will give an update if the promised output KW is attained in the future. Thank you Solar Optimum and I will be recommending you to all my friends.

Solar Optimum has been a 5 Star Experience in all categories from start to finish. What I'd like to write about specifically though is to recognize Solar Optimum's level of Customer Service and "Service After the Sale," so to speak. I DID have a couple of minor issues after activation, but Solar Optimum fixed everything in Lightning Speed. I literally called once in the late afternoon, and had someone at my door who resolved everything early the next morning. Nothing less than Stellar! Solar is a major and worthy investment, and every step of the way, I couldn't ask for a better experience. Everyone I've ever dealt with at Solar Optimum has been A+ and I'm VERY happy with our system. I don't know how they could be Better.

Quoting was fast and I liked that there was no pressure to sign a contract. They weren't the lowest-cost option but we had just put in a new roof and the roof penetration warranty was the best I found. The installation was very quick - we didn't have to be on-site for it. We had existing electrical issues with our wiring and electrical panel and Solar Optimum fixed them in-house at cost (a lot of solar installers don't do additional electrical work) and made sure our inspection passed. They also submitted all paperwork and were present for the inspections - made the whole process really easy and effortless on our end!

Really impressed with the professionalism, overall customer service, and quality of my new solar system. I went with solar optimum mostly because of their great warranties. They are 25-Years all across the board (Panels, Inverter, Racking, Roof, Workmanship, and Performance Guarantee) I was referred by my brother in law so seeing how attentive they are with his system now two years later makes me feel confident in their service.

Peter van der Pas

To be fair, Solar Optimum had just recently started doing business in Northern California in Summer 2019 when I contracted with them for a home rooftop solar installation. At the time they had very good reviews from customers in Southern California but none in the Bay Area. After my initial review here on Best Company, Alexander R, Operations and Maintenance Manager, contacted me to reassure me that Solar Optimum is responsive to my concerns and is there for after installation support, and indeed they have come out a couple of times in the last year to address fairly minor issues with the final install. It is this commitment to after-sale service that motivated me to update my review. My original review follows... Solar Optimum was unable to complete the job in the promised timeframe due to numerous errors and avoidable delays. Initial plans did not include all panels specified in the contract. This caused a delay in submitting plans to the city for permits while they were being corrected. The wrong panels were delivered to the job site. Again I as the customer was the one who had to check their work. Subcontractors ordered a main electrical panel for underground utilities whereas this is a home built in 1940 and all utilities are on a pole. This caused additional weeks delay. Solar Optimum scheduled building inspection for a day they were not ready and were not present on site when the inspector arrived, causing further delay. The final installation was completed in a good workman like manner and passed inspection by the city. I only wish the process was smoother and that there would have been no delays.

Alex dos Santos

Great company overall, had some issues with sales communication and post-install service. However, their management corrected any issues once alerted. I understand that residential solar is of less importance than commercial installation and maintenance--and I'm happy to queue up behind the squeaky wheels--however, the company has poor at responding to emails. In my business, I respond to all customers--big and small--quickly, even just to say that email was received and that a follow up would ensue. Other than communication issues, I would still recommend Solar Optimum with that caveat, and would ask them to improve by simply acknowledging emails even if just to say that a requests may take time to get to.

If you want to get solar in California, this is the place. I talked to so many companies and this place beat them all by far in customer service, warranties, pricing, financing options, and energy production from their panels. I've had them for a week and the solar panels are generating far more energy than they had projected AND they've offered to install something I asked for at no extra cost...just to be nice! Couldn't recommend them more highly.

The design process didn't go the best. They had to make three site visit to confirm the roof layout. After two site visits they sent me a layout. I pointed out that roof vents from the bathroom where in the way. They had to make a the third visit and re-design the layout. The installation process went well and smooth though and the system produces as designed. The permitting process went well too. Communication during design was 50/50. They responded to calls but not emails very well.

Solar Optimum itself was great, but the installers they hired were a nightmare. It was a fight to get the system installed within months of when it was originally promised. They failed multiple inspections with the City and I ended up calling the permitting office directly to sort out the issues that were preventing the project from being approved & it was clear the installers were being dishonest with what they were telling me in person was holding the project up. The only reason the system was completed before the end of the year (and I was able to collect the full tax credit) was because of the legwork I personally had to put in with the city. I felt like I was required to do far more than a typical homeowner ever should have been just to get things installed correctly and in a reasonable timeframe.

I had Solar Optimum put 26 panels on my roof and install a Tesla battery. The Panasonic panels were higher quality than those offered by a competitor. My electric bill has gone down to around $10/mo vs $400-600/mo last summer. The install went smoothly. I had a problem with a trench being left open at the end of the job that I filled in myself. The company refunded half of the bill for the trench which seemed fair. The solar system has been working fine and I have had no issues with the product at all. I would recommend this company.

From beginning to end it was a seamless installation. I also so appreciate the after installation checking that everysting is functionung the way it should. During power outages that was so re-assuring. This is a caring and good company!

A great company to work with. The installation went so smoothly and now that the system is up and running, they have been extremely helpful in answering any and all questions I may have. Installing solar was a stressful process for me because of so many unknowns, but so far, I could not be happier with my decision to use them.

My solar installation went very smoothly. First I was little upset why they are taking so long, but I was wrong. It really takes long time as so many steps are involved in it the installaion. Just to install the panels takes only 1 to 2 days, but lot of things go behind the scenes that I didn't know.

I met with 3 or 4 other solar companies in the years before meeting with Solar Optimum. The previous companies's representatives all lied to me or tried to distort the benefits. Solar Optimum told me the truth. The system was installed properly, works as specified and my property was treated respectively. What more can anyone ask for?

They got job done, but outside of promised time frame, with no acknowledgement for the miss. I was pushing things to move faster (to be expected from a customer), and sales rep emailed someone internally that I am 'tired of hearing,' (read: that I am not capable of understanding what they have explained before). He inadvertently sent me that email (smart move).

They designed a system for our needs and workers to our home to set it all up. They installed it and had the city inspectors check their work and all passed with flying colors. They answered any questions we had and even came out two times to make sure all things were going right. They flipped the switch and it all work like it should.

Like best: Once HOA approved, everything went smooth. High quality material, experienced crew who took care of property. Broken tiles, which is not avoidable, got directly replaced. Could be better: HOA changes were not communicated to crew, could stop crew in time. Not happy: Consumption meter coils not installed. Didn't tell me during installation. The braker panel was modified, could be installed during this. Unhappy they just wrote there was no space. I can't verify this statement. Overall the system rocks...went from $205 to $9.60 (PGE taxes etc.) and $143 credit for later (True metering). SolarOptimum designed very well the PV. Thanks for overall 5Star service. (Hope you can fix my consumption meter) ;) I got them referred from a friend and he is also super happy. Same professional result.

The salesman was very professional and answered all of my questions. I agreed to go with Solar Optimum because they were about $2k less than the competitor. I had to sign a separate contract for the battery and when I added the amounts together, I realized that the total amount was $2k more than the total quoted me. I went back to the salesman who told me there was nothing they could do. As I had already signed the preliminary contract and completed the preliminary site survey, I decided to proceed. I am less than 3 months in and the gateway, system controller, microinverters and battery quit communicating with the Enphase app for a week. The second time I called, I was told I needed to reset the gateway wifi connection. I did that and even though the gateway is successfully reconnected to the wifi, the system controller, microinverters and battery were not. A live view of the system showed that the battery was not discharging. A tech came out, but couldn't fix the issue. I got a call the next day from Solar Optimum saying that a software update not pushing through was a know issue and they were able to correct it remotely. The system is now working and I hope there will not be any more glitches or issues.

The Panasonic panels work great, and the Enphase system is especially good, providing a web site with all the information you could want on how the system is performing. My only issue was with the installation, which is not done by Solar Optimum employees, but by contractors. Better quality control is needed.

The whole process was smooth. I did run into a hiccup where despite calling out location of panels on new roof. Somehow SolarOptimum tried to place some panels on old roof and upsell re-roof. I had to call in a few times to get it sorted
