    New Roof and Solar

    My experience with Semper Solaris was excellent. The Crew was very personable and willing to answer any questions I had throughout the project. Both Paul and Christian kept me informed of what was happening each step along the way. They both were very responsive whenever I reached out to them. My overall experience was a good one!!!

    Ridiculous how they treat their veterans!

    Do not sign up for solar with Semper Solaris they do not follow through with customer service for Veterans! We have been fighting with them since Sept when our monitoring system SunPower stopped working and according to sunpower our equipment is out of date but because Sunpower is filling bankruptcy Semper Solaris won't service us! And according to Edison our system hasn't been working for the last 3 months, because of that we now have a $900yr end bill! Smh!

    This proves they have done nothing and will blame solar edge

    I've installed two systems with Semper Solaris. The first system was amazing the second system sucks. They have definitely gotten worse over time. I've had nothing but problems with my system from panels not working to batteries constantly charging and now the inverter has gone out and it's been 6 months of back and worth. They will blame solar edge equipment to prolong their BS the will blame Edison for not having to use the extra electricity used. I've had 3 years of hell including this one where my electricity bill pay back has been $3,765, $1,987 and now we are up to $1,748 already this year a long with our payment of $560 a month. They still haven't fixed my system so I'm having to use another company today to fix it which is going to cost an additional $2,000. Don't use this company ever they are terrible and will not do what their commercial states. The use the vet card to get your business but then leave you hanging in the end and will blame other companies. They will post after I send this saying things like we are so sorry for your inconvenience. But in the end I have the email and text messages and I'm looking for the best lawyer possible. Please please don't use this company they have turned into a bunch of money hungry individuals.

    The new inverter and one on the powerwalls

    Came out and gave me quote for a Tesla powerwall $13,250 for one (not enough close to what I need for my power consumption ) I live in a fire zone however they never mentioned anything about the SGIP rebate that has hundreds of millions available for battery backup. This is such a failure I believe. I was able to get 3 Tesla powerwalls ($40,000) for free with the SGIP rebate and I added $20,00 of solar from another company. I'm not sure why Semper Solaris failed to mention this but they missed out on over $60,000

    SCE $26,400 rebate check

    We had two Tesla Power Walls installed from Semper Solaris and can't be any happier. This group is professional and delivered everything promised. Our system installation was $33k however with the help from Semper Solaris we received a $26,400 rebate from SCE after it was all said and done. I would love to work with this group again if we have opportunity. Thank you Steve

    Hi had great experience with the semper Solaris crew,very professional and down to earth very great people skills. They work together they were great never saw them standing do nothing always working Very impressed. I've been in the hospitality industry for over 30 years. They definitely had the wow mentality in there work. I will highly recommend there work. Crew names are Adam, ,David, Emanuel, Raul, Scott,

    Water damage from the roof from a leak.

    Maybe you will actually return our calls after you see this review. We have tried multiple times to reach someone about this issues we are having with our brand new roof that was installed by you. No one picks up the phone, no one returns emails, no one calls back when messages are left. I would hate to go the legal route but I will if I have to. Our roof and solar system are over a year old and now we are dealing with this, which will surely turn to mold and rot and no one will return calls.

    "Too good to be true."…read more Literally that was my thought throughout my recent experience with UniverCity. I'd been stalled for a year with Tesla and was giving up hope I could get my solar expansion project in before the tax credits expire. I reached out to a few local contractors, and these guys came under every other bid. In design, they managed to fit more south-facing panels with limited roof real estate, compared to two previous designs I received. Every other contractor said any new panels would be incompatible with my existing system, which was a problem since I wanted the full capacity for the batteries I was adding. UniverCity said no problem. It ended up taking them three times as long to get the two systems talking to each other and they had to try two new panels before they could get it to work. But they didn't change the contract on me. There were some hiccups at the end getting through inspection. But they were fair, received my feedback, and got me to the finish line. David, Frank, Aaron - thank you. Just a terrific experience all round.

    I do not normally leave negative reviews, but after nearly 10 years, I feel it is important to…read moreshare my experience. Before posting this review, I made every reasonable effort to resolve these issues directly with the company. I sent a formal letter over a year and a half ago outlining my concerns and requesting assistance, but I never received a response. More recently, I sent another detailed email, giving the company 14 days to respond with a plan to address these longstanding issues. That deadline has now passed, and once again, I received no response. This company installed my solar system in 2016. At the time of purchase, I was given expectations regarding the amount of energy the system would produce and the savings it would provide. Unfortunately, those expectations have never been met. In nearly ten years, my system has never produced the level of solar energy that was represented when I made this investment. As a result, I have spent thousands of dollars out of pocket on Southern California Edison bills that I reasonably expected my solar system would significantly reduce. Instead of receiving the savings I was promised, I have continued paying far more for electricity than I ever anticipated. What has been most disappointing is the lack of follow-through. The company has been aware of issues with my system for years, yet they remain unresolved. Despite numerous phone calls and emails over the years, I have received little to no communication, no meaningful updates, and no proactive effort to correct the ongoing problems. There were also issues from the very beginning. When my system was installed in 2016, I was never provided with the monitoring equipment that was supposed to come with it, nor was I informed that there was a monitoring app available. Without those tools, I had no way of monitoring my system's production or knowing that it was consistently underperforming. After years of phone calls and emails to the corporate office, I finally got someone to come out in 2023 to install the monitoring equipment that should have been installed from the beginning. It was only then that I learned there was an app that allowed me to monitor my system. During that same visit, the technician determined that my microinverters needed to be replaced. The replacement microinverters were shipped to my home, and the technician returned to pick them up for installation. However, the work was never completed. The technician left with the new equipment and never returned to finish the job. Despite additional attempts to follow up, I was once again left without answers or a resolution. I understand that mistakes happen and that every company occasionally encounters challenges. However, this is no longer a matter of a simple mistake or a temporary inconvenience. This has been an unresolved issue for nearly a decade. My goal has never been to leave a negative review. My goal has always been to have the solar system I paid for perform as it was represented and to have the company stand behind its product and installation. Unfortunately, after almost ten years, thousands of dollars in unexpected utility costs, years of unanswered phone calls and emails, an incomplete repair, and two formal written requests that went unanswered, I have been left with no meaningful communication and no resolution. I sincerely hope this review encourages the company to finally contact me, complete the repairs that should have been completed years ago, thoroughly evaluate my system, determine why it has consistently failed to meet the promised production, and stand behind the product they sold me. If the company reaches out with a genuine commitment to resolving these issues, I will gladly update this review to reflect that experience. I would much rather write about a company that ultimately made things right than one that chose not to.

    We had our solar panels installed by SolarMax and our overall experience has been very positive…read more  From first contact to ongoing customer support, SolarMax has exceeded our expectations. We were fortunate to have Ruben G. as our Account Manager.  Ruben was professional, pleasant and knowledgeable -- carefully listening to my questions and concerns and also sharing knowledge so I could better understand the phases of installation. Throughout the entire process - from design to permits, documentation to electrical requirements, we communicated with the various SolarMax team members to make sure we understood what the next steps would be. Every team member was courteous and competent, all of them did their part to complete our solar panel and battery project. We are happy with the service and expertise SolarMax has provided us and would recommend them to friends who are considering solar energy.  To Ruben - our renewed thanks!  We appreciate you for your work. To the entire SolarMax team - thank you for making this happen!

Will update when I hear back. Would not recommend SolarMax at this point until they improve their customer service. Look into other companies and their service reviews since you will most likely have to contact them multiple times with questions about the system/billing. They were very prompt and quick with reaching out and getting back to us when they were trying to sell us solar. However, now that we have been customers for years and our sales rep left, it takes multiple calls to even get through to customer service and then multiple follow up calls after since they have to email other departments to get an answer and do not call back. It seems like they are short staffed and for a big company like this should invest in more staff for customer service. That way they can provide the same experience we received in the beginning. It's been almost a month after I initially contacted them and my question still has not been answered. Seems like there is only one customer service rep and she definitely needs help.

Natasha was professional and very clear with communication from the start. She set proper expectations on communication with Tesla would take a week or two. The day she received the go ahead from Tesla she called and scheduled the install asap 4 days out. Later the same day they had a cancellation and were able to get everything scheduled the next day. Anthony and Jeremiah arrived at the beginning of the arrival window! They were professional, great with communication, and ready to work. I had several questions and they were prepared for all of them and super helpful. The battery removal and install took less than an hour. Naturally Tesla's update took twice as long. LOL. Still total time was under 3 hours. I have managed 100s of installers and worked in Solar, this was a fantastic expierence! Because the Tesla 3 has more storage than the 2 I asked about adding some of my Breakers to the back-up and they had options for us to do that. Obviously we Highly Recommend This Team!

The installers were awesome and got me going quickly. So regarding the communication issues I had with the company, things happen, people get busy and sometimes delays do occur. I'm just glad we were able to get everything resolved. Pricing, I did get a couple of additional quotes and Option One blew them out of the water. Could it be those other companies assumed I needed the parts and labor? Maybe, but I was very clear that I had the parts already. Bottom line it never hurts getting quotes and going from there. Service, so I got all the paperwork done yesterday early afternoon and was scheduled today (5/1) at 8am. I do realize there needs to be a buffer between appointment time and actual arrival time, I usually just assume an hour after the appointment time. But the techs were here at almost exactly 8am. As I have very limited knowledge on solar panels, the fact none of them fell off my roof (panels or techs) and nothing blew up, then it's safe to say they did a fantastic job. In the end my system is fixed and I'm happy. Also if I ever need work done on my system again I'm calling these guys up.

    Absolutely First-Rate from Start to Finish When the fires…read morehit Southern California and we lost power for two weeks, something changed for me. I remember standing outside one night listening to my neighbor's generator roar to life again. It sounded like a chainsaw tearing through the quiet. Across the street, friends with solar and batteries had their lights on. Their kids were inside watching TV. Life looked normal. Meanwhile, I was packing up my family to leave our home. Rising electricity rates, AI data centers consuming massive amounts of power, and talk of double digit rate increases made going solar the right thing to do. I researched heavily. Built a spreadsheet. Interviewed over a dozen companies. Got bids through Energy Sage, cold called installers, and asked around for referrals. I wasn't looking for a sales pitch. I was looking for people I could trust with my home and my family's security. Infinity Solar felt different from the start. I didn't have to deal with brokers or middlemen to jack up prices. They are family owned, in business over 25 years, BBB A+ rated, and 5 stars on Yelp. Tim, the owner is a C10 licensed contractor, sets the tone for the entire company. His pride and commitment to doing things right shows up in every person on his team. Sara, our project manager, kept everything organized with clear, proactive communication. Blake handled the maze of permitting. If you've dealt with solar permitting in California you know what a mess it is. State, county, city, and fire department all with their own rules. Blake stayed on top of all of it so I didn't have to. Joel made sure the job site ran smoothly. The crew deserves real recognition: electricians Adrian, Ivan, Salvador, and Christian; roof lead Arni; installers Jose, Gabriel, Kieren, Israel, Erik, and Robert; and Deyvis helping with inspection. They showed up on time, worked hard, kept everything clean, and answered my endless questions without ever making me feel like I was in the way. Construction always has bumps. Permits get revised, inspectors want changes. What mattered was how Infinity handled it. Calmly, professionally, and without disappearing. Tim must be a good boss and take care of his people because this is a crew of highly skilled workers who take real pride in what they do. The day the system went live felt like a turning point. Our first outage was December 23rd while setting up for a Christmas party. Power was out over eight hours. The lights never flickered. I only knew because the app alerted me. Tim included a Solar Insure 30 year warranty covering panels, microinverters, wiring, and roof penetrations, including labor. It's backed by an A+ Superior rated third party insurer and is transferable if I sell my home. An installer's warranty is useless if they go out of business, so this gives real peace of mind. Because I verify everything, I called Solar Insure, Enphase, FranklinWH, and REC directly to confirm Infinity is a Premium or Platinum installer with each. They are. I'll break even in 8 years at current rates, sooner when rates keep climbing, and you know they will. But more than savings, it's peace of mind. When the grid goes down, our house doesn't. Infinity Solar gave our family back a sense of stability. I'm grateful we chose them.
