The Good

  • High-Quality Equipment and Monitoring
  • Industry-Leading Warranties
  • Several Flexible Payment Options
  • Premium EPC Company
  • Certified Battery Installer for Tesla and Enphase
  • 16+ 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, QCells, 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 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 Master Elite Contractor and CertainTeed Elite Shingle Master for all residential roofing needs.

Industry-Leading 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.

Several Flexible Payment Options

Solar Optimum offers a variety of ways for customers to pay for their solar energy system, including upfront purchase, loan finance, and solar lease. 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 16 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.

16+ Years of Experience

Solar Optimum has over 16 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 indicate continued service, but it also speaks to extensive industry and operational experience.

Positive Client Reviews

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 Panasonic, REC, QCells, Enphase, Unirac, GAF, CertainTeed 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.
bestcompany guarantee

Best Company guarantees your satisfaction if you choose a company that has earned this distinction. If you're not satisfied after 30 days, simply let us know and we'll give you $200. Yes, it's really that simple.

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

Shining Bright with Solar Optimum! ☀️ 10/10 Highly Recommend! Long story short, my builder-installed solar system was just too small. Adding additional panels on top of my townhome was a big decision, and I'm thrilled I partnered with Solar Optimum! From the initial quote to the final activation with SDG&E, their team was professional, efficient, and incredibly helpful. Here's why I loved working with them: • Competitive Pricing: Their quote was competitive without sacrificing quality. We went with Panasonic panels and Enphase microinverters, the two bests in the industry! • Seamless Process: Every step, from surveying and design to installation and activation, was handled smoothly and efficiently. • Top-Notch Service: The team was knowledgeable, responsive, and always happy to answer my questions. They truly went above and beyond to ensure my satisfaction. • Speedy Activation: My system was activated with SDG&E much faster than anticipated, thanks to their proactive approach. • Zero Issues: The entire process was smooth and hassle-free. Overall, I can't recommend Solar Optimum enough! They made going solar a stress-free and positive experience. If you're considering solar in Southern California, look no further! They're the absolute best! P.S. Minus the cloudy weather in San Diego, I'm generating plenty of my own clean energy and finally saving money on my electric bill. Couldn't be happier! ⚡🌞

My husband and I are researching solar and battery storage as we live in an area of Southern California where the grid unfortunately goes down several times a year. After meeting with 4 companies, Solar Optimum stood out the most! Our energy consultant was very friendly, knowledgeable, and understood what we were looking for. He was amazing and we are excited to get the process started.

I reached out to Solar Optimum for my getting my house ready with solar support. My project was time sensitive as I wanted to get into CA's NEM2(NET metering 2 program). Solar Optimum prioritized my ask and provided - permits, applications, design, procurement and installation well within the deadline. Also the price they quoted was lower then other companies I reached out to.

On Monday, 12/4/2023 Solar Optimum completed the installation of our solar system that consisted of panels and batteries. We are extremely pleased with the experience from the beginning to the end. Our journey began with twelve vendors; we narrowed it down to three before ultimately choosing Solar Optimum. They were reasonable priced, and the process took only two months from the time the contract was signed to receiving permission to operate (PTO). Our Solar Consultant Mikkel M was very knowledgeable and walked us through the entire process. Davey W the account coordinator provided the best service. He was always available and when I left messages, he got back to me immediately and addressed our concerns. When we received the first draft of the layout, we had some questions and change requests which Gina S from the project team addressed and updated the design. Once the design was approved, Solar Optimum took care of all the behind-the-scenes tasks, e.g., permits, city approvals, utility interconnection, etc. The installation was then scheduled, and the equipment arrived first thing that morning as planned. The crew showed up, worked into the evening, and completed the entire installation all in one day! The crew worked efficiently and neat and cleaned up everything before they left. The inspection was then scheduled for Monday the following week arriving sometime between 8am and 5pm. The representative from Solar Optimum arrived at 7:30am. He powered on the system, tested, and performed all the configurations. By 10am the inspector arrived, and we passed! PTO followed the very next day, and the monitoring app was up and running. Additionally, Hannah O helped us tie up the loose ends (warranty info, invoicing, etc.) and made sure we were completely satisfied with the product. Thanks to the Solar Optimum team for going above and beyond expectations.

Solar optimum did a great job with my solar project- I got a lot of quotes and did tons of research prior to moving forward- I decided to go with solar optimum because of the demeanor and the pricing was by far the best by $8K while providing the most comprehensive material and service warranty. Sure the red tape and regulations imposed in California took some time- but solar optimum did everything necessary to secure NEM2.0 deal with the utility and the construction actually took no time at all 2 days- 1 for solar, second for upgrading my main panel. I got 32 panels and they have been really supplying home with nearly all of my needs. They also have Panasonic panels and the best inverters in the residential game (emphase). I love my system as now I am able to save some extra month to month. I am definitely looking to add batteries through them! My favorite thing about solar optimum is their friendliness and their service, it's not a money grab for them- they actually care about their customers.

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!

Solar Optimum stands out as an excellent company for solar panel installation. After thorough research, comparisons, and obtaining quotes from five different companies, Solar Optimum emerged as the top choice due to their competitive pricing. Juan A, the Energy Consultant, exhibited exceptional professionalism and provided valuable assistance throughout the process. He meticulously managed each step, from calculating the required number of solar panels based on electricity needs to designing the layout for optimal placement on the roof. Handling the city permit application and coordinating the installation team, the process was efficiently completed in just a few days, delivering both timeliness and quality in installation. Their post-installation services included coordination with SCE for inspection and system activation. Moreover, an added bonus was Paola C, the Interconnection Coordinator, who initiated the application for an Incentive Rebate worth close to $2,000 through the SCE-Self Generation Incentive Program. Overall, I am extremely pleased with Solar Optimum's services and would highly recommend them for anyone seeking solar panel installation.

I am very happy that I have started my solar project with Solar Optimum and with a very competent team. I was delighted with project management from start to the end. Very efficient and well organized within short period of time. My project included 12 REC410AA Pure-R with Enphase microinverter and an Enphase 10T battery with backup option with a competitive price. Solar Optimum surveyed the house roof with drone for best location in respect to sun and shadings, and they filed for the available solar rebates. I felt I was in good hands.

Mike from LV NV Henderson, NV

After negotiating with 4 companies this year I finally went with the Solar Optimum team due to the expertise, quality of equipment and price which seemed to be the best of the companies I dealt with. Installation was just completed 7/3/23. The team took care of all interactions with city and NVenergy, except i coordinated with my HOA, which was very helpful through the whole process, permits and inspections. There was a minor issue initially with 4 panel connections which the local team, led by Zhora, immediately responded by taking care of the problem. Had another issue when my internet connection was lost and didn't reconnect to the Enphase module which reports system status. This was resolved by Zhora working with the Optimum customer service home team and now everything is working smoothly. I wanted to thank the local team, led by Zhora, for quality installation, responsiveness to take care of these hiccups, communication and overall exceptional customer service from everyone I've dealt with at Solar Optimum. Very impressed with the process from start to finish and even more importantly how responsive the teams have been to ensure system is continuing to perform and certainly one of the best customer service companies I dealt with in a long time. Thank you all!!

We selected Solar Optimum after a failed contract with another installer. We are extremely glad that we did. Solar Optimum's customer service has been exceptional. They returned all of our calls promptly, kept their commitments, and kept us informed. Their installation team went above and beyond. As an example, our local utility was delayed by 4.5 hours for the power turn on after the meter and panel upgrade. Solar's Optimum's team member Robert and Andrew stayed on site to ensure that we would have power. Since we live in the California desert, getting the power back on was critical. Solar Optimum also did an outstanding job of managing the process with our HOA, utility, and county permitting authorities. We highly recommend Solar Optimum. They are first class.

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.

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.

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.

I installed my solar from Solar Optimum on September 2022. My overall experience is positive although there were some hiccups during main panel upgrade and city inspection. I also wanted to beat NEM 3.0 deadline. I finally got my PTO on January 2023 and I can use solar now. Thank you SO for this. Some suggestions to SO: 1. Customers might want monitoring in their system. Maybe SO can install a slightly big panel so that they can enjoy production and monitoring. 2. Improve email communication also. There were delay in email and I had to call main office several times.

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 was professional, from start to finish. I had my initial consultation with William. He was able to walk my project through every step and provide me with five star customer service. I am now saving hundreds of dollars on my electric bill. I would highly recommend Solar Optimum to any family or friends looking to go solar.

Very fast and clean installation (a couple of hours), no power shut down during installation as I was concerned. After that the system works well, the control panel and App are easy to use. Customer service is great, called them twice for some small questions and every time was satisfied.

Solar optimum has been very responsive and customer service has been great. They were very efficient with their proposals and install. When we had an issue with turning on the micro inverters, they made it a priority to get the system up and running

Great price on system. Excellent follow up from start of process all the way after installation. Installers were very good and made sure to check in with me throughout the install to make sure I was given options on instal methods. They really surpassed my expectations all around.

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’m writing this one Year plus from installation Andy we’re still extremely happy. The app works very well and there have been no glitches. Below is what I wrote last July, and I still think the same. Professionalism, follow-through and meticulous attention to details

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.

I am very happy with my Solar Optimum project on 6/10/2023 in Pacifica/Daly City, CA. I had previously signed on with another company in order to make the NEM2.0 deadline. However, I was taken aback by the amateur, unprofessionalism, and speed salesman tactics from this company. Fortunately, I was able to walk away and sign up with Juan A at Solar Optimum. Immediately I received professional emails and notifications. They quickly put my applications together and design (8.8kw + Tesla Powerwall 2). The actual installation was not till later (2 months); however, I was fine by that since I still got NEM2.0 approved. When installation came, I was thoroughly impressed with the crew (Kien T). They were quick, efficient, kind, and courteous. They even painted the conduit and walls. No tattooed prison freaks. I was able to leave them unattended. All in all, I will seek out Solar Optimum for future projects (if I get another house) and I will refer them to my family and friends! Thanks, Solar Optimum. Now time to make PG&E pay ME.

My house needed extensive renovations, which took place in 2019-20. My general contractor brought in a subcontractor to install solar panels, but I could not afford a Powerwall at that time. When I finally could, I called the installer, but his company was unable to procure one. That's when I found Solar Optimum. They were easy to work with, and the cost was close to what my original installer had bid. They took care of everything, including inspection by my small city's infamously picky inspectors. The man who installed the Powerwall was not only meticulous, but willing to explain everything to me during the installation process. Everyone I spoke with by phone during the process was helpful and answered all my questions as they arose. My only job was writing checks and using the labels Solar Optimum provided to FedEx them. I highly recommend this company.

I started this solar project at mid-Jan 2023, and tried to beat the Apr’s California NEM 2.0 deadline. The whole process is very quick and smooth. Solar optimum provides very very competitive price comparing to other big name solar companies. Since everyone tries to install solar before NEM2.0 cutoff time, I have to keep close contact to Solar Optimum to make sure I didn’t miss any documents or waste any time. All the people I talked to are very knowledgeable, professional. They guide me step by step to complete whole process including some design change and financial question. I will highly recommend Solar Optimum to others.
