If you're even thinking about going solar in San Diego, stop scrolling and call Semper Solaris -- and specifically ask for Jonathan Kibler. What started as a "straightforward" solar install turned into a colossal, multi-agency obstacle course, and the only reason this project crossed the finish line is because of Jon's leadership and Semper's depth as a company. First challenge: SDG&E. We ran into delays with little to no communication, and it took real effort just to get clarity on what the issue even was. Once we finally got answers, we learned the real problem: our neighborhood already had too much solar. SDG&E claimed the existing transformer and service drop couldn't handle the additional load and initially wanted us to pay to replace both. For most homeowners, that would be the end of the project. Jon and the Semper team didn't accept that outcome. They pushed, escalated, coordinated, and ultimately overcame an issue that would have stopped many other installers cold. This wasn't just technical work -- it was advocacy. Second challenge: the City permitting process. The building department held our permits because our home was incorrectly flagged as a historical property (it isn't). Again, another moment where this could have easily stalled or fallen apart. Jon stayed on it, worked through the city's process, provided the necessary documentation, and kept everything moving while keeping us fully informed. Through all of this, Semper also: Helped structure financing so we weren't forced into bad decisions Coordinated a roof install alongside the solar project without missing a beat Hustled to work us into the schedule so we still had a shot at the federal tax credit Communicated clearly and consistently during what became a very stressful process What impressed me most is that Jon never treated this like "just another job." He owned it. He communicated. He stayed accountable. When this project ballooned from simple to insanely complex, he stayed steady and focused on the outcome. Solar is easy when nothing goes wrong. Semper Solaris proves their value when everything goes wrong -- and they still deliver. Five stars isn't enough. If you want a company that will stand with you when the system works against you, Semper Solaris -- and Jonathan Kibler -- are it. read more

Please don't use this company. I Called and explained my issue with backup battery system including my specific model and make. I was told that they could fix this specific model. After paying a $300 solar health checkup I was informed they can't fix the equipment I own and suggested replacing my equipment. Please do not tell customers you can fix their equipment if you can't. Now several weeks later going back and forth with different customer service personnel I was told they will not refund my $300.00 Terrible way to run a company, just use someone else. read more

Semper Solaris did a great job installing our Tesla battery. Made everything fit with our existing solar equipment. Matt Kazan was very helpful and checked on us every step of the way. read more

Semper Solaris - Battery panels along with 2 separate solar systems. - Solar Installation Near Me - El Cajon, California

Bought in 2015 now 11 yrs later (after initial 10 yr warranty runs out & 25yr extended warranty kicks in) we have more than struggled to get assistance. Not generating solar this electric bill is up. Took 3 wks & numerous unanswered calls to get some to check system. Now waiting another week with no return calls to find out when it will be fixed. 1 month & still not fixed and horrible customer service for returning calls let alone even answering the phones. read more

I worked with Phil Valverde to get Tesla Powerwall 3's added to my home. He made the process straight forward and ushered the project through all phases: planning, financing, installation and is still in touch should we need support. I'd recommend Phil and Semper to anyone interested in getting work done. read more

Janice Lee was the Service Project Coordinator for a warranty claim issue I had for our roof. Semper Solaris installed solar panels years ago and it was determined that there was a small leak from an area where the panels were screwed into. This is going to happen from time to time I'm guessing even if the install is perfect. My claim process was very smooth. Janice was very helpful and accommodating. I have all the confidence that if there are any issues with your install, Semper Solaris is good for it to make it right. Thank you Janice you are the best! read more

December 2025 Let the light shine down! Amazing experience working with Rhami Hasenin! He is SO on top of it and an all-around great guy. As soon as we met Rhami, we knew our search for the right solar provider was over. He always kept us abreast of the promotions and incentives available and helped us secure an outstanding deal on our system. On top of that, Rhami drastically minimized our costs when the state requested changes. He is very knowledgeable in the field and capable of educating customers at any experience level. I sincerely wouldn't consider getting solar from ANY other company than Semper Solaris due to how exceptional Rhami is. THE best! February 2026 This is an update to my previous A++++ review now that install is finished, inspection is passed, and we're operational. Couldn't ask for more! Vote for Rhami!!! read more

I have used Semper Solaris for roofing and solar. I am a big fan. Now I used them for HVAC. Great again. The technician, Alberto Rodriguez, is a winner. Alberto is very knowledgeable and personable. He was very thorough in his Inspections and testing. He explained his findings in detail and clearly. And his recommendations balanced proper function of equipment with cost effectiveness. Alberto is my go to for HVAC. Highly recommend Semper Solaris and Alberto. read more

We are still in the process of finalizing our solar system, but at this point just awaiting SDG&E to approve turning it online. Paul was very helpful throughout the process, explaining what our options were, and finding the system that was right for us. He was very up front, and did not try and up-sell us on any portion of the system. He took personal care to see how things have been progressing throughout the process. If you are looking into solar with Semper Solaris, ask for Paul! read more

Very competitive pricing and excellent service when I had issues with the inverter several years after installation.

The gentleman who came to our home was polite, on time and very friendly. Not only that, he did a very personal updating of my SDGE site which had to be updated. It was complex and he did a great job of getting the meter, and me, up to date. read more

I'm really grateful I ended up working with Mark at Semper Solaris- he made the entire process easy to understand and stress-free. From the start, Mark was super down-to-earth, patient, and never pushy. He took the time to explain everything in a way that made sense, and he walked me through each step like a true partner in the process. You can tell he genuinely cares about helping people make the right decisions, not just closing a deal. His response time is incredible -- emails, calls, texts, you name it, he's right there with clear answers and helpful guidance. I never once felt lost or in the dark about anything. Mark's professionalism mixed with his friendly personality makes him one of those rare reps you actually look forward to working with. If Semper Solaris leadership happens to read this: Mark is a huge asset to your team. He's the reason customers like me feel confident, informed, and well taken care of. Bottom line: ask for Mark. You won't regret it. read more

We highly recommend Semper Solaris for both solar installation and roof replacement. Our sales representative, David Bell, was an absolute joy to work with. He was professional, easy-going, and never once pushy. He gave us all the information we needed and then the time to discuss things privately, which we really appreciated. When it came time for the actual work, Semper Solaris delivered exactly what they promised. The crews arrived on time, communicated clearly throughout the process, and finished within the estimated timeline. Truly, at times it felt like they were ahead of schedule. From start to finish--David Bell's guidance, the project leads for both the roof and solar, and the smooth final paperwork--our experience was exceptional. We feel confident recommending Semper Solaris to anyone considering solar or roofing projects. read more

We used Semper Solaris to install an HVAC system, whole house, fan, solar panels, and a Tesla power wall. Phil Valverde was our contact person and did an amazing job. He walked us through every step of installation and was always available to answer our questions. Phil made sure that the workers were on time and we were happy with every step as they were completed. We would definitely recommend Phil and Semper Solaris to anyone interested in new Solar and HVAC systems. Thank you again Phil for the five star service! read more

New install for solar panels and a battery. Was installed within a day and a several weeks early from what was expected. From the research I did the price was comparable to other providers in the area and matched other quotes. We had Phil as our rep and we never felt pressured during our interactions to sign with him over other providers and we got timely updates from him during the project. read more

My sales associate was Mark Ivory for my window replacement. He was awesome. He scheduled the quote visit within 24 hours. Answered all me questions right off the bat and then when I had follow up questions, he got back with me almost immediately. No delays. No waiting for days for a response. He called back within 10 minutes. That rarely happens with service industries in my experience. Everything went smooth as silk. Additionally, the follow up appointments for installation went very smooth as well. No delays. Everything was done in a timely fashion. Very happy with the customer service to date. Zero issues. read more

Highly recommended! Our system was running in less than 30 days from our first meeting! I called five companies for quotes and I was most impressed with Semper Solaris's initial contact team. They answered my call and followed through immediately. It only got better from there. Paul, our sales rep, came to our home and took the time to really understand what we wanted. He was able to thoroughly explain the system he recommended and show how it was the best fit for us. We received another quote, but it didn't feel like the right set up for our needs. Also, that company had a lot of negative reviews regarding delayed installations, etc. Paul's quote was about the same price, but seemed more fined tuned to using our existing system. The overall positive reviews for Semper Solaris helped make our decision to go with them. Paul helped us move through the steps between contracting and installation at lightning speed. We were motivated to get the system up quickly to take advantage of longer summer days and have the extra solar power for using AC. They came out quickly to do the initial inspection required to complete the project workorder, then gave me all the support documentation for HOA approval. After I returned the HOA approval, they handled city permits very efficiently. Throughout this time they sent emails updating me on each step of the process. Both teams who came to the house were courteous and focused on getting the job done to my satisfaction. They took the time to explain things to me and met our requests for how to place the equipment and run the conduits from the roof. Mark, our rep during the installation phase, kept in contact and answered questions. Overall, this is a fast and efficient team with great customer service. read more

So far the installation went well, waiting on the final parts to actually start using the solar system. Paul Rampoldi has been a great coordinator that has been willing to help at any time. read more

I would like to recommend Jonathan Kibler, salesperson, from Semper Solaris, if you are thinking about re-roofing your house. We were interested in the highest fire-resistant roof. Jonathan came to our home, examined our roof, and sat with us for a long time to review all our options. He had materials to show us, and was knowledgeable about the benefits and price points of every option. We came to an amiable agreement without any pressure from him. During the phase preceding the actual roofing work, Jonathan responded to all our preparation questions quickly or directed us immediately to the person who would handle it. The job is almost finished now and the Semper Solaris team, as a whole, is way better than the contractor we hired 20 years ago to do our roof. P.S. They also did our solar panels and battery wall, with which we are well pleased. read more

I had solar installed by this company a number of years ago. They had the Sun Power panels I was looking for so I decided to use them not knowing about their work ethics. A bit over priced and when they were working on my tile roof they broke a number of tiles which is to be expected. I figured they would replace them but all they tried to do is glue them together and it looked like a mosaic tile feature. I called them on it and they came back and replaced them with my spare tile I had in the yard for my own repairs down the line not even asking if they could use they. I figured they would bring their own supplies not scavenge from my supply. Also I noticed they didn't seal the roof jack properly where the electrical conduit came through also. It's like I had to continuously check their work and instruct them on how to do it properly. The most recent complaint is I have a broken panel that needs replacing and I called and emailed them about trying to figure what model panels I had and to buy a new one. And they don't even respond and get back with me. Just be careful. I guess they only respond if you're spending thousands. read more

During my research for an upgrade of my existing solar panel system without batteries. I took serval estimates from three local companies here in Southern California. Two of the three companies spoke my language Zero Export which would allow me to retain my Net Energy Metering One (NEM 1) status with SDG&E. Jonathan Kibler with Semper Solaris came in and not only assisted me with remaining on NEM 1, additionally he informed me that Semper Solaris was offering a Thirty percent discount off installations this year. That's a BIG Plus during these economic uncertainties. That 30% allowed for reduction in not only my monthly payments but also the interest cost over the life of the loan in the tune of thousands of dollars. The installation is complete we are currently waiting for city and utilities inspection. Further reviews to follow. Thank you Semper Solaris and especially thanks to Jonathan Kibler. read more

We recently moved into a new home and were referred to Semper Solaris by my father-in-law and brother-in-law who both had great experiences with them. Upon reaching out on a Friday, Mark quickly texted back, and made himself available within the next fifteen minutes to hop on the phone and talk about adding solar to the roof. After answering all of my questions, Mark further made himself available to come by the house the next day, despite it being a Saturday. On Saturday, Mark came by the house and sat with my wife and me for about an hour and explained all of our options and his recommendations, as well as the reasoning and the pros and considerations for each of them. Before leaving, Mark put together and sent me quotes for each of the options discussed and offered to reconnect to answer any questions that we might have. For both options, Mark recommended what made sense for our circumstances (for both today and looking at the horizon), instead of trying to sell more than we wanted or needed. Later that day, Mark sent a nice follow-up thank you text message and offered again to answer any questions. I had a few and asked if I could call him with them, and didn't even have to, as he quickly called me instead. During that call, Mark was able to answer all of my questions, and promised to quickly turn around updated quotes. Shortly after, updated versions of both quotes were in my inbox ready for our final review and signature. We signed later that night and are super excited for our system to be scheduled and installed. Thanks again to Mark for being so great to work with! read more

It all started with the sales representative, Sandy Peisner, not only showing up on time; but showing up to listen first and not trying to full court press me from jump. I was looking to add a battery system to my existing solar system. Sandy narrowed down the exact needs of our house and he came up with the best game plan. We went over all the details of my electric bill and came up with a perfect set up. Semper was on top of keeping me updated with every next step...from the financing, to the install schedule. Just had the battery installed the other day. Even the installers were just as professional and ready to work as the sales rep. Seems like this is a common denominator for this company. I've kept all their information in my contacts so I can refer them to anybody who's interested. read more

They installed solar on our neighbor's property and needed to break up some of our concrete driveway to get to the access point under our property. THERE IS STILLA GIANT HOLE IN OUR CONCRETE OVER THREE MONTHS LATER. They have not fixed it. It's extremely unsafe. read more

Unfortunately, this has been a very frustrating experience. Our solar system has not been producing since April, likely due to a panel or equipment malfunction. I first contacted the company about this on November 20 and have made multiple follow-up calls since then requesting service. Despite months of outreach, no representative or technician has come out to inspect or repair the system, and there has been no meaningful resolution. We are continuing to pay for a system that is not working. I would strongly caution anyone considering this company to ask detailed questions about post-installation support and service responsiveness, as that has been extremely disappointing in our case. read more

Semper Solaris has been a lot of help. From the very start , customer service is top notch. 5 years later and still there when I needed them, without hesitation! Thank you ! read more

This company has very poor customer service! I had my solar installed by them but it stopped working so I called to get someone come and check to fix it but you can't even get a schedule from them. Every time you call it's answered by customer service and the only response you get is they'll contact the department so I can get a schedule and should wait for a call or email that will schedule me but it's been more than a week and there's no email ever sent to get a schedule. Mind you this is just getting a schedule for repair, you never get one even if you call and follow up. Their answer is always wait for an email to get a schedule which they never do and in the meantime I'm here waiting for nothing. It's terrible customer service! Don't do business with this solar company or you'll end up in frustration and headaches like me. read more

Semper Solaris has exceeded my expectations, installing my solar and Tesla battery with impressive speed, and outstanding customer service. Paul Rampoldi was my rep, and has offered in step advice and consult throughout the process. Highly recommend. read more

Genevieve J. was great and listened to our needs. We did have a quote from another provider. They both were comparable in price, but Semper Solaris sold us with their knowledge and straightforward service and pricing. Once the date of installation happened, we are close the third week with a city inspection scheduled next week. read more

I called there phone and took my information for 3 times also email them, I have problem with the solar system they install it I just finish calling them for same problems the phone will disconnected because they pick up the call to sell new system read more

I referred my neighbor to Rob for installing solar and they were beyond pleased with his communication and flexibility. He answered all their questions up front and couldn't be happier with the service! read more

Working with John Kibler on our solar contract was an excellent experience. He took the time to walk us through every detail of the agreement and made sure all of our questions were answered clearly. His professionalism, patience, and knowledge gave us confidence in moving forward. I also liked how he's able to text us for communication as I like to refer back to my questions and his answers. John explained the options thoroughly without pressure, and he was quick to respond whenever we needed clarification. We were able to ask him to "dumb" it down for us. We truly appreciate his honesty and expertise--highly recommend him if you're considering solar! read more

A year after my solar installation, I noticed some water leaks in my ceiling and reached out to Semper Solaris. They responded right away and sent someone to take care of it. Brian was amazing--he spent an entire day carefully inspecting every part of my roof, fixing everything, and even running a thorough water test to make sure no leaks remained. I felt very confident in the quality of his work. Janice, the coordinator, has also been outstanding. She has consistently followed up with me after the inspection to check if the area was staying dry and free from moisture. That kind of ongoing care really impressed me. Finally, Austin came out to restore the inside of my home. He closed up the holes, repaired the peeled paint, and remade my ceiling so it looks just like it did originally. Overall, I'm extremely happy with the service I received. Semper Solaris really stood behind their work and made sure everything was taken care of properly. I highly recommend them for anyone considering solar. read more

Sandy has been a HUGH help in coordinating my roofing and Solar removal and reinstallation. Sandy is responsive to all my needs and questions immediately! He is easy to work with and has a pleasant personality. I am a 77 yr old female that has never taken on a massive project like this. I highly recommend Sandy as the best coordinator! Thank you Sandy! Sylvia read more

We wanted to add a solar battery to our current system and knew that Semper Solaris was our go to! We were connected with Mark Ivory and it was easy and quick! We encountered some challenges (on our end) and Mark was incredibly patient with us and communicated all along the way! He has been outstanding to work with! I highly recommend Semper Solaris and especially Mark Ivory. read more

Angie was our customer service representative. She was incredible, very professional, extremely knowledgeable and easy and fun to work with. She took us through how to change our power walk back up setting for more storage, but more importantly, walked us through how to analyze our current rate plan with SDGE, which we did and saw that we had a better option for savings and earning back money....music to our ears. It was the best experience I think we've ever had with a CSR. She's a keeper and valuable asset for the company read more

Semper Solaris replaced my roof along with removing and re-installing my solar panels. The solar system I have was installed by Semper Solaris several years ago. Overall I am very satisified with the project with one exception which I will point out at the end **. This was why I selected 4 stars instead of 5. The entire crew was very professional, on time and very efficient. They kept the area around the house clean along with removing all debris before they departed. The roof also looks great. I would like to point out several key folks for this project and highlight the great work of the entire crew. Mark Ivory the consultant for both my original solar install and this roofing project. He answered all my questions and assisted with changing the drip edge color which was a minor contract modification. Christian the project manager. He kept me up to date and helped to resolve a couple minor issues such as paint touch up. He also assisted with arranging the painting of the drip edge. He is a veteran and it was great to work with him as a veteran myself. He speaks Spanish which was helpful. An all around great person. Tony Q who removed the solar panels. He is an awesome "one man" crew. He was very efficient at removing the solar panels by himself. Impressive how hard this man works. Edgar who led a 2 person team re-installing the solar panels. Very professional and efficient. He also assisted with readjusting my security cameras as they probably got bumped during the installation of the new roof. **The one issue I have not resolved is an area where rain water comes off the roof and runs down the side of the house on the wall. My stucco is new and white in color. I am afraid this area will become stained once it starts raining. I did bring this up before, during and after the project was completed and an attempt was made to resolve. I performed a test with my garden hose and could still see water running on the wall (see pic). I was really hoping this would get resolved.** A couple minor notes that did NOT affect my score: Limited drip edge colors. This is more of an issue with suppliers than Semper Solaris. I ended up having mine painted at an additional cost. Glad I did because it looks much better when the drip edge matches the color scheme of the house. Semper Solaris does send me a lot of emails (too many) :) read more
