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, LG Solar,, 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.

Researched solar companies for 1 year before deciding to go with Solar Optimum installation in the summer of 2018. Salesman (also an electrician) was knowledgeable as he was able to answer all of our questions. No issues with install and no leaks in the roof to date. All panels working. Company responds promptly to questions. Recommend Solar Optimum.

I had solar panels installed on my roof a few years ago. They were great, fast and efficient. The staff is very nice, competent and friendly. Now however, they are super slow for my 2d installation on my daughter's house. May be too much demand or Covid??? The liaison person at the customers'desk, Britnnay S is very nice and helpful

If there was a way to rate this company with zero stars I would, as it is I can’t and feel that the one star is too generous for the experience. I will say that the solar panels are installed and operational but the experience to get to this point was the worst I have have had when hiring a contractor. The company uses inexperienced employees probably due to the wages they pay and I felt that the little I knowledge I have with solar was much greater than the people I was dealing with. And each step seemed to have a another new person to interact with. I started at the beginning of Nov and was up and running at the end of July. I will say that the COVID shutdowns with the city added to the time frame but the panels were installed before hand and the additional charge for the panel not going back to the original location that I contested kept holding up the work. They could not explain to me why they wanted more money for this even though the drawing that accompanied the quote showed it to the right of the original location. It was taking to long to hear back from them each time and I finally paid in protest to move the project along. Other than when they wanted money the communications were non existent. I always had to call to see when someone was coming to the house to work. After l made the final payment, I was told that a manager or the owner was going to call me, never heard from anyone. I guess they got their money and that was it. Just a bad experience

We had Solar Optimum install our panels last year, and we've been really satisfied with what we got. We used energysage to search for a provider, and the quote we got from Solar Optimum was one of the best values for the quality of work that we got. The were a little difficult to get a hold of during the months that we waited for the installers to come, but once the date arrived, they did a fast and professional job. A year into our installation so far and we have no complaints.

I became a Solar Optimum customer in November 2019. I had interviewed two other solar companies and found the Solar Optimum plan exceptional and what I was looking for. The plan and the implementation was perfect for my energy needs. My bills for electricity went to zero from an average of $325 and with the storage battery i was selling power to the grid. The service from day one was the best as I said. Everyone one I had reason to deal with has been attentive and responsive to my request. The whole experience was flawless.

We completed our solar install with solar optimum during our house renovation and were very happy with the service. Before contacting Solar Optimum, I contacted a different installer who felt like the install would be too difficult. Solar optimum had no problems at all. They were completely professional and helped walk me through the entire process. Would highly recommend.

Prior to engaging Solar Optimum, I did comprehensive research on solar installers and systems. I contacted 6 solar companies based on reviews of customers and their ratings by industry observers. Based on many factors, including but not necessarily limited to competitive pricing, ease of communicating with staff, product offered, willingness to accommodate special needs, contact with past customers and, particularly important to me as I was about to embark on a major investment in a large system, the assurance that the salesperson would continue to be my main contact person throughout the process from contract negotiation to issuance of the final PTO (permission to operate the system by the utility agency ) after installation of the complete system, it was a "no brainer" that Solar Optimum clearly was the right choice. But the person who made it extra special and was the determinative factor in my final decision to go with Solar Optimum was Joe H. I am an inquisitive perfectionist, so my inquiries can be a little overbearing at times. But Joe patiently addressed each of my inquiries politely and comprehensively, offering his honest opinion even when many salespersons would be less than candid on some of my questions/issues. At the outset, Joe assured me he would remain as my primary contact person throughout the process and address any issues that I might encounter with faithful attention to my best interests. He did just that throughout the entire process -- he is a rare breed of salesperson. Furthermore, based on my contacts with other Solar Optimum staff during the process I felt they were very professional and especially attentive to maintaining good customer relations. Thank you Solar Optimum! I strongly recommend Solar Optimum and salespersons like Joe H.

Solar Optimum and their entire team was as close to perfect as a company can get. The entire process was so unbelievably easy - they took care of everything! Permits, applications, rebates, financing, installation, using the best #1 solar panels/inverters/batteries in the industry right now and with an unbeatable warranty (I had two other estimates done before going with this company - Solar Optimum just couldn't be beat on price, service and warranty). Best of all, they were ALL so genuinely nice, professional, PATIENT, responsive, helpful and attentive to our specific needs (admittedly, I am a tough client). One of our neighbors went with a highly rated national company and had endless complaints - couldn't get the service and help he needed, ever. Another one of our neighbors tried going directly through Tesla for solar, etc. and Tesla rejected their job because their roof made it too difficult to install panels. So I referred them to Solar Optimum and they are on their way to having their solar installed! Thank you Solar Optimum!!!

I researched among 3 solar installers and Solar Optimium was one of them. Their prices weren't the cheapest, but I believe in you get what you pay for, especially for a project of this caliber of my home. I felt their service and product selection are the best in the industry. From the initial appointment to obtaining Permission to Operate from my utility company took about 4 weeks. Everything was on point and the actual installation finished in 2 days for 20 panels x 330 watts/panel. I also opted to have the Level 2 outlet installed for EV vehicle so I can include this in the 26% Federal Tax Credit. I would definitely recommend them to family and friends!

From the moment we reached out to Solar Optimum (based on good reviews), we were very pleased. We were able to schedule an appointment for them to come and go over things with us very quickly. Everything proceeded efficiently and we were clear about what the process would entail. There was absolutely no cheesy, hard-selling, annoying sales tactics that we experienced with other companies. The pricing was also so much better than the other gross companies we had talked to. There is a lot of scamming out there with solar companies, so we were very happy to have found one that was as reliable and professional as Solar Optimum has been. Every step of the process was handled professionally and with great customer service. They walked us through everything in detail. We felt we could trust them 100% and that's huge. They told us we couldn't put in as many panels as we wanted because of shade issues - which was not the case with other companies. We needed to make some adjustments to our roofing and they helped us find an amazing roofing company that handled their work perfectly. We have been very pleased with the reports that are sent every month, and the app that is available to monitor production. Overall, we are really happy we went with this amazing company.

After shopping and comparing solar system with other competing solar companies, Solar Optimum was our best choice. We have no regrets getting the solar system from Solar Optimum. The customer services were great.The sales Rep was very good, and answered questions patiently. He explained to us how the solar works what to expect and actions to take if we encounter any problem. Also, we were concerned about possible leakage or damage to the roof after the solar panel installation. But no leakage so far even after the rains. I will surely recommend Solar Optimum to my friends.

Solar Optimum has been outstanding! Before Solar Optimum, my electric bill ran from $300-$600 per month. Since Solar Optimum, my highest electric bill was one time $30.00, but since that one time, it has never exceeded $15.00 per month, and I have 2 large refrigerators and air conditioning units for upstairs and downstairs in my home. I am very pleased with Solar Optimum. I highly recommend using them.

Our experience with Solar Optimum has been great! After buying my dream home which is a small farm, my husband went in search of solar. After installing a new roof, we had 3 companies come out. All 3 were pushy, expensive, not flexible, wanted to force us to lease and only had Chinese made panels. We found Solar Optimum through a friend. They came out and gave us multiple options of product and service! In one day an entire system for a 1/2 acre was installed and running. We own everything, NO payments or lease! Panels have 50yr warranty, Canadian made of vinyl. The system connects through the internet but we are upgrading that to cell tower connection for more reliability. Now I want to add more panels and back up generator. Solar Optimum is here, qualified, and knowledgeable to make all that I need a reality. I would never recommend another Solar company, this one is the real deal!!!

It’s been about six months since we had solar panels installed by Solar Optimum. We have been very happy with the system. No longer do we need to worry about an expensive electricity bill, while allowing our AC to be on as the intense heat waves rage on. If you’re considering going solar, I strongly recommend calling Solar Optimum. Their pricing was the most competitive, and their sales specialists were friendly, professional, and very knowledgeable, providing detailed answers to all the questions I had about the benefits and money-saving. The installation took only two days, and the warranty is for 25 years! We really like the simple App that continuously monitors the energy production.

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.

I researched many solar companies before finding Solar Optimum, beginning with the sales rep to installation and post installation. This company goes over and beyond expectations always very friendly and professional. They care about their customers, before, during and after installation. I would recommend this company to family and friends..

Last year Solar Optimum installed our solar system and we are extremely happy! Our sales person Ivan and the installers were very professional and we couldn't be happier. Highly recommend Solar Optimum.

The representatives that we came in contact with starting with the very first phone call I made to the company for information on their system, the Administrative staff, the Technicians, the Electrician, Project Manager, and Accounting. Everyone was courteous, professional, knowledgeable, friendly, and executed customer service. We are pleased with The service this company provided from start to finish and I received my first month billing from SCE in the amount of $9.59. Good job SolarOptimum and keep up the good work. Sincerely a Satisfied Customer.

I have been a customer with Solar Optimum for almost 5 years now. They did a great job installing my solar panels and have provided excellent customer service whenever I need to follow up with them.

I had my solar system installed by solar optimum about 4 years ago. They were very efficient, the installation was seamless and the system is still working great without any problems ever. I highly recommend this company
