5 stars This was my third time using semper for solar installation. We had another kid and with all of us using more devices, we watched our bill creep back up there and wanted to bring it back down. Bob King was our salesperson. He was very knowledgeable and informative.. Bob presented solutions - added panels under rule 21 and a two batteries - that made sense and fit into our budget. Our crew arrived on time, were courteous, polite, went over everything they were going to do. They finished on time with a great looking install. With Semper, you get step by step heads up on everything that's happening, and when it's going to happen, though things usually happen faster than the estimated times. Working with the same people and the same company over the course of ten plus years feels really good. I would recommend semper to anyone who's looking into solar, or batteries or roofs. Five stars. read more

I had a great customer service experience with David Fontaine. He was extremely helpful in deciphering a lot of the electrical world jargon and helped me better understand how to read my electric company's bill for future reference. He was very patient, kind, and knowledgeable, and never once made me feel uncomfortable for not knowing much about the process. I truly appreciated the time he took to explain everything clearly. Excellent customer support! read more

I am very pleased with Cherice Hess - she been amazing - in follow up and arranging the replacement of the 4 panels under warranty after a long wait. She and her team also came up with idea to make the new panels - slightly larger work - by rearranging them together so they still look good. Thank you Cherice read more

I would like to express my appreciation to David Fontaine for his professionalism and dedication to ensuring I have all my questions answered. Also, helping setting up my system for optimal performance. His patience and passion are examples for customer care quality! Thank you, David! read more

We purchased system in September 2025. It now has not been working consistently for 3 weeks and it's only 8 months old. You call and you get an answering system. They don't come in person to fix the system and want to do everything remotely. Their customer service is horrible but their sales team is fantastic. Beware! Would not recommend and would never buy from them in the first place. read more

Gus, Julio, and Richard set the bar for what great service should look like. They showed up exactly on time, were incredibly thorough, and clearly take real pride in their work. Every question I had was answered clearly and patiently, which I really appreciated. This was hands-down one of the best service experiences I've had. Semper Solaris is lucky to have a team like this--highly recommend! read more

RUN. I see these ads out there that now they're offering plumbing - good god, RUN! I paid for a 50 year roof and I'll be surprised if it lasts 5. Jaxon Raab that liar in sales said they don't use subcontractors, that was a full out lie. Subs aren't even from the US. They literally PUT SHINGLES OVER A HUGE HOLE and tried to close the job as final. Thankfully the inspector made them redo the entire roof. Oh and I never got the battery I wanted. Thanks again Jaxon... not enough that my unit almost burned down my house from the arching in the panel.... My project was supposed to take weeks, it took a full year. I'm glad they lost money on my job. Serves them right. Enphase product is good, but find anyone else to install it. read more

The initial contact was outstanding. Staff friendly and quick response . From there is did not do so well. 1. The individual who was sent to give me the quote, Cody, was late with no call or text indicating that he was running late. I had to call. 2. Once here, I learned he had not done gutters or the type of corners I was having trouble with. I only hire people direct who have done the work themselves. 3. He tried to upsell me with other services. Running through a list. Tried to sell me solar, roof, air conditioning, house wind. I already had solar with a well known company that is very much still in existence. But he did not even recognize the name of Sunlux, assumed they were out of business. (Nope) 4. Never received the quote he promised, to be sent hours later. Seems their focus is really solar or air conditioning. Not gutters. Why even quote me then? I said it was an extremely small project with photos. I liked the initial appointment staff, was even ready to hire them in the spot if the quote was reasonable... but the lack of follow through and extreme high energy and loud voice of the estimator, ended that . I was expecting a person who would do the work themselves or who leads a team. I got someone who had no direct experience and needed a computer to give a quote. No thanks. Waste of time. read more

Exceptional Customer Service and Integrity - Jesus and Terrance Went Above and Beyond I've worked with Semper Solaris for several years and continue to be impressed by their professionalism, honesty, and customer care. When a recent issue arose with my electrical panel, Jesus and Terrance handled it with transparency and integrity. They took the time to investigate, clarify the situation, and ensure I fully understood what had happened. Even though the problem turned out to be unrelated to the solar system, they still went above and beyond--personally fabricating and sending replacement solar decals for my new panel at no charge. This level of service is consistent with every experience I've had with Semper Solaris. In the past, they promptly reimbursed me for loss of solar production and replaced faulty equipment without hesitation. Their dedication, responsiveness, and commitment to doing the right thing make them a company I completely trust and highly recommend. read more

This company is the worst. They do not know how to install a roof or fix the roof they installed. We had our entire roof (pitched and flat) replaced by them in 2018. We have had the flat part of the ceiling leak EVERY YEAR since they fixed it. We call, they schedule us, someone comes weeks later and they say they "fixed" it but then next time it rains it leaks again. They blamed our vents so we were stupid enough to pay these people to remove the vents because we didn't want to void the warranty by having someone else do it and guess what? Now the roof leaks in DIFFERENT parts. Worse part is that now we're starting to see STAINS on the ceiling from WATER DAMAGE. The last guy said it doesn't affect the integrity of the roof but he found wet spots THROUGHOUT the ceiling 2 weeks AFTER the rain. I have a toddler in here and they want to claim that a ceiling that is still wet after 2 weeks of no rain is safe??? I just HOPE that there is no mold, mildew, it wood rot in between these layers of wet wood! My husband has been calling and they are giving him the run around about scheduling someone to come. I tried calling and when they did call back they called to say they had no updates on when someone could assess the roof further. I have written a review in the past about our issues with the install and the first leaks, it's lost in all the other complaints they have about leaking roofs. If you still are on the fence about using this company you can read all of those and save yourself the trouble we didn't. Avoid them! read more

I purchased solar panels and a back up bettery from this company for my home in Buena Park. They are quick to respond for sales, now that I need warranty service it has been a nightmare to get them to come out. Going on 4 months and still can't get them out. I received a call from Kristina and assured she will follow up, no surprise at all that they have yet to resolve my issue. I also received an email from a Raymond Torres, see attached screenshot. I've replied to that email several times with no response. I called customer service and they say that case number is closed. I truly hope they can better their service, as I originally chose them because they are veteran owned and operated. read more

Semper Solaris - Case number - Solar Installation Near Me - Santa Fe Springs, California

Gil from Semper Solaris introduced me to SCE SGIP program which saved a large chunk of $ on my home solar project. I'd meet with sales people from 3 different companies and they new nothing. Gil, on first meeting me accessed the situation and said I might qualify for the grant. Now I have 36 panels and 3 Tesla batteries running grid free and it only cost me 1/3. Semper Solaris installers were professional and kept me updated thru the installing process. I would highly recommend them. read more

We had a Solar Edge inverter that needed to be replaced. We placed a call to Semper Solaris to troubleshoot the problem. The following day they called and set up an appointment to have a technician connect virtually with our system. We received a call from Josh Demangelaere the service tech. Josh had already found the problem and ordered a new inverter from Solar Edge, the Inverter manufacturer, and had set up delivery and explained that Solar Edge would come and install it when it arrived. Thanks Josh! Great job. read more

Just went solar with Semper and they were the best! From start to finish they provided everything one could ask for, great products & an awesome experience. They're not the cheapest, but as with all things in life you get what you pay for, and quality is what they've got! Thank you Semper for making going solar a simple and easy process. My electric bill is no longer an issue and I'll never have to deal with power outages again! read more

I hired Semper Solaris to replace my roof, since they had previously done my solar. They also removed the insulation and reapplied new. There were numerous problems, things that were promised and then not delivered on. They left an open pipe, that went into my electrical box. I spent many calls and weeks, before someone came to look at it, then nothing. I finally went to the hardware store and bought a cap myself. Worst experience ever! 5 years later, I'm having my hvac company check why one room doesn't get enough air out of the duct. Upon inspection, there is a broken duct in my attic, heavy rodent infestation, that had gotten into the duct work and the plenum. So, I now have to have all the insulation removed again, replace all the ducts, which were only 16 years old, to discover that there are at least a dozen holes from the attic to the outside. Semper Solaris replaced the entire roof and did the insulation, why was I never informed about these holes and why did they not cover them. I have now spent more money fixing this mess, than the roofing job cost originally. Worst experience of my life. I would strongly recommend that no one ever use this company, especially Veteran. I would give no stars, but they require at least one, which is not deserved. Thanks for Nothing Semper Solaris. Bob read more

Semper installed our solar and Tesla batteries about 3 years ago. One of the Tesla Powerwall failed and Josh D was able to contact Tesla who diagnosed the problem and a new Powerwall battery is on the way. I didn't have to do anything, the issue was addressed and taken care of. Now just waiting for the Tesla battery to be ready for Semper to install. read more

Excellent service. Very responsive and informative. I strongly recommend Semper Solaris. I initially tried other solar companies and was definitely disappointed. Semper Solaris is top notch. Ben Awe read more

Semper has great sales (for the business) but the rest of the process sucks. We had two Powerwalls installed and had a major issue where the installers burnt out the bus on my main panel. It took YEARS to get them to even acknowledge that it was an issue but proceeded to say the panel was like that prior to installation of the batteries. Fast forward a few years and my house almost burns down do to a smoldering main breaker that was overloaded by the subpanel that Semper installed. Again, no response from semper. Hell, I even reached out for a quote to install a new main panel. All I got was crickets! Fast forward again 6-months and there is a recall on the Powerwalls. So, I call Semper and they are friendly and quick to get the replacements. Now they text to schedule and say they will charge for the service call and labor! I contacted Tesla and they confirmed the recall is at no cost to the customer. Semper response...go find another company to do it, we don't make enough from Tesla (paraphrased). I will never do business with Semper again and will encourage others to look elsewhere. read more

had a ton of repeated issues and time waste with an expensive system that was not working. I was eventually escalated to Cherice Hess who was outstanding and quickly got things actioned and fixed requiring less of my time and ultimately getting everything working correctly. I am still not happy to have had to pay $750 for a service on a 60k system that required so many repeat visits and calls. But at least it is fixed and Cherice made things happen. read more

Cherice Hess was assigned our repair request. Since the outset she was attentive, courteous and professional. Our repair was done in an expeditious manner. My wife and I were both extremely pleased! read more

I have never written a review before but I had to. WORST customer service I have ever experienced and hoping to spare you. Installed a solar battery - from the day it was first installed to operating it took over 4 months. Upon inspection, the inspector literally said there is so much wrong, I don't know what to write. Semper refused for over a month to come out and check what they could fix. Eventually they did and got reinspected and failed again. Explanation...It is okay we messed up, that is why we have inspectors to tell us what to fix. There were wrong breakers installed, breaker box installed wrong, wiring done wrong, units in wrong location, too close to water source, no base that was required...and so many more. Once again was slow to be willing to come out and fix. Third time was more errors and had to do again and finally on 4th try got it. Flash forward - one solar battery died - I have now been over 3 months trying to get an answer when they will look and have had 15 calls and just get run around on warranty. Worst part is - they have a generic customer service who you leave a message with. They will call you back 1 time - about 2 days later. If you don't answer - you will have to start over as they won't call back and can't email them. The receptionist will tell you this is there number one complaint but the reps will tell you they have NEVER heard this... Anyways - no good deed goes unpunished as tried to support the military business but this has been a disaster... Ironically different company - Ecoforce did my solar panels and had a great experience but they didn't do batteries at that time. read more

My neighbors did hours of research and shared with us that Semper Solaris was the best around. Bob King came to our house to meet with us and was super helpful in explaining everything that needed to take place for us to get solar and stop paying the super high electricity fees each month. The install went great and we ended up needing a new roof as well which Semper also installed, and looks SO much better than before. The crews that came were really great. Polite, on-time, and helpful explaining through any questions we had, and above all, clean! They picked up and left things as good if not better than they found it. We have a big house, 3 stories, around 3,750 sf.. It's been a few years since our roof and solar were installed and our electricity bill averages around $150 per month instead of around triple that before, or even more during the summer. I highly recommend Bob King and the entire Semper team for excellent customer service and follow through. read more

Semper Solaris - This is how they look 5 years after the install, after washing them today. - Solar Installation Near Me - Santa Fe Springs, California

I paid Semper Solaris to put in an air conditioner in my house. Years later when I had someone out to fix something, the technician was a certified HERS rater( they come and make sure everything is installed correctly and up to code). This technician told me that my unit was missing a "return air plenum" He explained it is in the manual and is supposed to have one. Well Semper Solaris is avoiding my calls so I guess I'm off to small claims court. I am very disappointed with their customer service which is slow and lacking. Funny how when they want to sell you something they are right on it but when there is a problem... crickets. They have lost my further business. I DONT RECOMMEND ! read more

I had a great experience with the technical support team person Angie Corsaro.She has excellent knowledge and insight experience of the Solar System and I am sure Semper Solaris is proud to have Angie on board with them. Good luck Angie You're an asset to Semper Solaris with your in depth knowledge of the Solar System read more

Angie was such a pleasure to talk to and shared her expertise in regards to our solar panels, batteries and general knowledge of our system. I'm so glad I had the opportunity to learn about our solar panels and how to maximize their efficiency and I'm excited to reap the benefits of the changes that were made. Angie you were amazing and I look forward to contacting you in the future if I have any further questions or concerns. Best of luck. Regards Gail R. read more

Title: I'm a Veteran -- Semper Solaris Should Be Ashamed I chose Semper Solaris in part because they promote themselves as a veteran-owned company, and as a veteran myself, that actually meant something to me. Unfortunately, this company has completely failed to live up to the values they claim to represent. I had a solar system installed about two years ago, and everything worked fine until recently, when the main breaker inside the Tesla box started tripping. Since then, I've called three times. I spoke with Agarfield and Leah, and each time I was promised a call back by the end of the day. It's now been days -- and still no response. Zero follow-up. No technician. Nothing. There's no escalation path, no accountability, and frankly, it seems like they're avoiding me entirely because this is warranty work -- not a new sale. It's incredibly disappointing that a company that wraps itself in the flag and talks about "honor" and "integrity" can't even return a basic customer service call. If this is how they treat a fellow veteran, imagine how they treat everyone else. I expected better. I trusted Semper Solaris -- and now I deeply regret ever doing business with them. read more

Came out for a gutter estimate and just tried to upsale me on solar panels, A/C, roofing, etc. Then their estimate was twice as much as any other. read more

I made a warranty claim on one of my panels which was operating below par level. It was easy to report the problem but difficult to get a response from the company. It's been 6 weeks without a reply or some sort of action from this company. They claim the customer service is beyond comparable when trying to sell their product. But yet here I am waiting to get this unit replaced with disappointment. I would never recommend this company to anyone. This company is what's wrong with this country. Unreliable. UPDATE: 3/11/2024 I finally got a response directly from Cherish Hess and totally hit it out of the park. She was able to get immediate action from her staff to resolve the issue. I'm really pleased with the outcome after her involvement. read more

Semper Solaris - Back up batteries, control box, new fuse boxes, and 22 solar panels all installed in ONE day. IMPRESSIVE WORK - Solar Installation Near Me - Santa Fe Springs, California

This review is for the exceptional consultation with Alex Darr. We had a lot of questions about getting additional solar and a Powerwall battery. Alex was thorough and very responsive to emails. After talking to multiple solar companies, I enjoyed how Alex was not trying to give me the "salesman pitch" but just sticking with the facts and anticipating issues that would arise by tilting panels on a flat roof. I do a lot of research before moving forward with a project and Alex definitely addressed the concerns and regulatory limits for these projects that I would have eventually asked. I'm moving forward with Semper and hope the quality is consistent throughout the rest of the project. read more

The service is missing. Semper Solaris will do everything to get the sale , however, if you want this company to honor its commitment to deliver quality service for warranty, they will not provide. Don't waste your time calling them for any new product service or warranty service read more

I can't state how EXTREMELY satisfied I am with my battery install! I was so happy with my actual solar install prior that I called them again.

Thank you Terrance and Andres for being professional, explaining everything and staying to get the job done! 5 stars!! read more
