I have not picked a solar company yet but the experience with Pey has been fantastic. I have learned a lot from him. I don't think you would go wrong with choosing this company. read more

Absolutely do not use this company! I signed a contract with Cosmic Solar & Roofing to install Solar Panels on a ADU we are building. I gave an initial deposit and was told the next step would be to pull permits. What actually happened next was they came onto my property and installed solar panels on the ADU without ever contacting me, making an appointment, or getting any kind of approval. They never spoke to me once -- they just showed up and did the entire installation without my knowledge. It wasn't until they contacted me demanding full payment that we realized they had installed the Solar Panels. ( again this is on an ADU so I never even knew someone was on the property working) They have now demanded full payment and have filed a mechanic's lien against my home even though the system is not operational and the permit has not been signed off. I made numerous calls and emails to Pey and the owner Bahram Shadzi and did not receive any response. This behavior is outrageous. I have now filed a complaint with the Contractors State License Board. Stay far away from Cosmic Solar & Roofing. read more

Cosmic Solar installed two FranklinWH aPower 2 backup batteries on my home. Their price was the best of the three installers I contacted. The entire process went smoothly and much faster than I had expected. The batteries were up and running in less than 8 weeks from the day I first requested a quote over the phone! The entire team at Cosmic were very friendly, professional, and in constant communications with me. The quality of the work was exceptional. The crew cleaned up the work area each day before leaving and was happy to answer my many questions I had regarding how the batteries operated. I highly recommend Cosmic. read more

This was my second installation performed by Cosmic Solar. Everything went well- quoting process and sequence of events was clearly explained in detail, as were payment milestones and expectations. Paperwork and permits were handled smoothly by their office and technical personnel. Roof work and installation were performed on schedule as promised and work was done neatly and the install site left clean and scrap free. Inspection by city engineering was handled professionally by Cosmic and Permission To Operate granted before end of year so I qualify for tax benefit of the install. Technician helped me setup the Tesla battery app on my phone with appropriate settings to maximize benefit or the solar/battery installation. I highly recommend Cosmic Solar for roofing and Solar installation- very professional team! read more

Cosmic did a great job putting solar on my house. I went with the enphase and REC system. They handled everything like getting the city approvals , design , & installation , they setup the enphase app as well. My system has been working flawless for three months now and I am happy with their service and would highly recommend them . read more

Cosmic installed our solar system back in 2014, and we have never had any problems with it. Over the years, our 30 yo roof began giving us problems, and we didn't want anyone else to remove our solar panels, so called on Pey and Cosmic to come out and take a look at it. He explained what they could do to fix and update it, gave us a quick turnaround on a quote, and we were sold. The team came out and removed the panels, did a lift and relay on the roofing, replaced the felt underlayment and rake and ridge tiles, and added O'Hagin vents. The roof looks like a new roof and we couldn't be happier. The Cosmic office kept us updated throughout the process. Big thanks to Pey for answering all our questions and keeping in touch with us, and Eddie and the roofing team and Hector and his solar team for being so courteous, cleaning up each day and doing such an excellent job. Thank you Cosmic! read more

Cosmic Solar not only did an excellent job installing our solar equipment, but they have provided exceptional customer service ever since (we installed in May 2024). This weekend, I discovered my storage battery was not charging properly (of course, these things always happen on the weekend, right?). Even though I knew the office was closed, I sent an email to the service manager, Khi, so he would see it first thing Monday morning. To my surprise, I received an email back that day saying he would have a technician out as soon as possible on Monday. At 8:05 a.m. on Monday, Cosmic Service Tech Javier was at my door. He quickly and efficiently diagnosed the issue and had my system working properly within minutes. Now that's what I call service! Mary L. read more

Cosmic Solar gave me a competitive quote for an Enphase-based solar installation. Honestly, I had some cheaper quotes from other places but one of them literally had their salesman quit who then recommended I go with someone else. I liked that Cosmic Solar were a local company with an experienced crew. They have been very responsive throughout the sales and installation process even though my HOA was totally dropped the ball and dragged out the process longer than was legally allowed. The installation went smoothly once scheduled and inspection was completed promptly as well. Even with the dwindling daylight hours of November I am getting enough power storage to eliminate power draw from the grid from 4-9PM, when SDG&E takes their pound of flesh from everyone with their ludicrous peak rates. read more

These guys are awesome. Good pricing, out to the house quick, and fixed our issue. We used them for a solar inspection when we bought our house and for maintenance when our system (not from cosmic) stopped working. Cheap fix and very honest. Took time to explain everything. We worked with Khi and Javier who were both great. Highly recommend their services. read more

We have just completed a project including a new roof, 27 solar panels and two battery packs. The Cosmic Team could not have done a better job. From design, engineering, permitting, rebate application, to the actual field work, each of the Cosmic employees we interfaced with were knowledgeable, friendly and informative. We highly recommend Cosmic for your roof or solar installation project. read more

Great service and product . Easy to deal with . Very trustworthy staff and install was done in 2 days

We had our Ground mount solar panels & dual batteries installed back in December through Cosmic Solar. From conception to completion the whole team was great to work with. Like any responsible homeowner we did our due diligence and looked at other vendors & getting quotes. We chose cosmic for their knowledge of city ordinances & regulations, and the fact that they have done ground mounted solar. Every other vendor told us things needed to be changed or, something needs to be moved, but not them. Because this team works so effectively with the city that was not the case and sure enough everything is permitted and passed both local and SDG&E inspections. The installation team was great & respectful to our property. They did not begin to dig or make any cuts without our approval. We were involved from the first whole being dug to them turning the system on. I highly recommend Cosmic Solar for your solar project, you will not be disappointed. Kudos to you all! read more

Cosmic Solar was awesome start to finish. Everything flowed well, and the price was competitive!

Khi at Cosmic Solar is outstanding! Every time I needed service, he was very responsive and professional. Best service all around.

Cosmic Solar just finished our solar project. First of all, they were very professional, provided great communication, and were very easy to work with. The initial amount they quoted is exactly what we paid for the job, no surprise additional charges. We have a steep cement tile roof in certain areas and they easily handled the installation without damaging one tile. We highly recommend Cosmic for your solar project needs! read more

We were very happy with the service that we got from Cosmic Solar and Roofing. From appt, to quote, to getting our system up and running was much faster then what I am seeing from other companies. It took less then two months to complete it all. We had several quotes, and they had the best price for less panels that had higher capacity then others that wanted to put up more panels. 3 months in with Solar and we are happy. Easy people to work with, panels were up in one day. read more

Cosmic installed a 20 panel system with Tesla battery. It was done in conjunction with a new roof installed by a different company. All the people I dealt with at Comsic were outstanding. The sales rep (Ken) was knowledgeable and stayed with the project from beginning to end. They coordinated with the roofing contractor to install the standoffs after the underlayment and before the new shingles were installed. Then they came came back and ran the cable in the attic after the insullation guys removed the existing fill and before they blew the new stuff in. And they promptly finished the job of installing the panels and getting everything hooked up. The crews communicated well and were very courteous. Everyone involved was working for Cosmic - no subs as fare as I know. Overall it was just a very nice experience! read more

Cosmic Solar represents the best in class when it comes to solar sales, installation and technical support. I would echo what prior positive reviews have said about the company. From Ken in sales, to Ashley and Arlene in the office to Pey at the helm this company delivered on everything promised. Cosmic Solar streamlined the entire process and took great care in communicating with us and keeping us posted every step of the way. My wife and I were relaxed and confident during the installation process and we could not be more satisfied with the final result. We highly recommend Cosmic Solar for your solar energy needs. read more

Cosmic Solar is a great Small Business Family Solar Company and very dependable This is our second Solar install we have done with them. The 1st was at our Business in Spring Valley this was a 19kw system Then this 2nd one was with the new Tesla powerwall 3 Battery system with built-in inverters There techs were great installing the system never had any issues The back end was great taking care of all the permits and paperwork Always on time and kept us informed with the process And for sure any upgrades or future Solar or Batteries we my need Cosmic Solar will be our Company of choice Over the years we have told many our friends and our families about this company If there was a 10 Star we would give this Company a 15 Star read more

OMG - Cosmic Solar is the Real Deal! So much so that if there were a way I could award 7-stars on this review, I would award it. That is because from the first phone call and meeting with Ken Davami to the point of installation (with CJ & Hector) and final details (with Javier), the entire team that makes up the Cosmic Solar family.....performed FLAWLESSLY. In early April my wife and I watched in horror a news report which announced that SDG&E would be increasing rates by a crazy amount in 2024 and again in 2025. At this point we had already seen our rates increase from an average $180.00 per month to over $400.00. This news report also announced that effective April 15th, 2023 net metering 2.0 would expire and net metering 3.0 would begin. In a panicked state the following morning I began researching, calling and scheduling interviews with various solar companies. After interviewing the 4th solar company and based on the great reviews I read, I called Cosmic Solar and scheduled an interview with Ken Davami who works as their Senior Solar Energy Consultant. During Ken's presentation, My wife and I could sense that Cosmic Solar was a "super star" company that was superior to all the other solar companies we interviewed. Within the span of 45 minutes Ken delivered a professional, no pressure and no-nonsense presentation that helped us go from knowing very little about the complex world of solar energy, to knowing everything we needed to know in our quest of making a well-informed decision. After signing the contract with Cosmic Solar, I called and spoke to Ashley Alvarado (their Administrative Solar Specialist) more times than I care to admit with countless questions at each step of the way. During each call, Ashley who seemingly knows everything about the solar process....happily and patiently answered every question I had regarding my paperwork that had to be submitted to my HOA, questions I had about paperwork that had to submitted to SDG&E, as well as, many other questions. At a certain point I also spoke to Pey Shadzi who works as the Cosmic Solar Operations manager and solar panel design specialist. He helped refine the panel design and layout to fully maximize solar production based on how the sun hit our home over the course the day. On the day of installation, I was introduced to Hector and CJ who are two Cosmic Solar installers. Over the course of two days, both Hector and CJ showed up 5 minutes early and professionally and efficiently worked through two hot days to install the solar panels within the timeframe that had been predicted. Along the way, both communicated exceptionally well with what the plan was for each day and where they were in the installation process. And as if there were not enough.....just yesterday, Cosmic Solar sent out their master technician (a gentleman named Javier Ortega) to perform the final electrical details. In addition to connecting all the wires between SDG&E meters, RMA & the Enphase inverter, Javier stayed two additional hours to be on-hand for the final inspection conducted by the city/county inspector that day. Wow!!!!! At this point, I think it is important to note, that during the period of April, 2023 through July (like me) most San Diego homeowners realized that with electricity rates set to increase and with net-metering 2.0 set to expire....NOW was the time to act and act fast. So, at the time we selected Cosmic Solar, consumer demand for solar energy had already sky-rocketed to a point where solar companies were under tremendous stress and immense pressure. After serving 30 years in the Marine Corps during stressful and challenging times, I have learned the best measure organizational excellence is by how well teams, players and companies operate under stress and extreme pressure. Without being overly dramatic, I can honestly say that based on how well, smooth and efficient Cosmic Solar operated under the intense pressure created by overwhelming demand, they have proven to be among the elite level solar companies in all of California. It is a company that promises what it will do.....and does what it promises. From the first phone call to the final inspection, what impressed us most was the extraordinary pride, passion and genuine joy displayed by each and every member of this family-owned company. In a day and age when companies place more emphasis on numbers and production, it is refreshing to find an awesome company that values superior customer service & prides itself more on building personal relationships than maximizing profit margins. As such, my wife and I feel supremely blessed to have called, interviewed & hired Cosmic Solar. Now, if we can only convince our San Diego Padres to spend their next spring training watching Cosmic Solar in action maybe they could learn a thing or two about the power of teamwork & go win a championship read more

I hope that this is my last update to my review of Cosmic Solar. I am upgrading them to 2 stars. It appears that they have FINALLY fixed our system. I might have given them 3 stars if Pey had not lied about me calling their office to curse at the staff. I cursed a blue streak at whoever called ME in the evening. I think it was Pey himself, and I had repeatedly told him not to call, as I wanted all communications documented. It appears that Pey is throwing his vendor under the bus. Remember, this is HIS vendor. And when he is giving you a sales pitch, will tell you that they are the best that there is. But if 10 visits over 3 months to diagnose and replace faulty micro inverters seems reasonable, go ahead and use Cosmic Solar with their SunPower equipment. read more

Went with a local recommended company and have not been disappointed. Larry my sales rep has went above and beyond to make all go well. He Knows the biz, which is helpful because i do not! Knowing that Cosmic services my area, they assured me that it is a win/win situation to make me satisficed. They have done that. From my initial meetings with Larry onto the install crew. They were all professional. My system looks great, very clean and painless install, and a smooth transition into switching from SDGE to solar. Only regret I have so far is that I should have went with them sooner. If you go with Cosmic ask for Larry, he will take care of you! read more

Had a great experience with Cosmic Solar from start to finish. We had a battery installed on our existing solar system and the whole project was very positive experience. When we get more panels installed in a few years, we will definitely use Cosmic Solar again! read more

It was such a pleasure to work with Cosmic Solar from start to finish. They were honest, upfront, and very professional. We bought a home that had solar panels installed years ago by a company that went out of business. We knew the panels weren't performing like they should so we reached out to Cosmic Solar to help us with the issue. They were immediately on it and helped solve our issue in no time at all. I highly recommend this company and would gladly work with them again! read more

We were referred to Cosmic Solar from a close friend in the neighborhood. Compared with other pitches and quotes we'd received up to that point (over 15 companies in total), Larry stood out from everyone else. His calm, knowledgeable, and deliberate approach caught our attention and it quickly became obvious that all our other options were just average. We lost count of the number of times Larry came to our home to ensure we had a great experience and everything we needed. The jobs themselves weren't easy, by any means. We purchased both pool solar and PV (photovoltaic) solar from Cosmic, and suddenly my wife and I were faced with some difficult logistical decisions. Where do these two massive objects go? Our roof wasn't an option, and there were trees everywhere on the property. Ultimately, over 200 feet of significant trench had to be dug for the PV solar, numerous trees had to be removed for both solar arrays to fit, and the driveway had to be excavated for the electrical conduit to reach our main power panel. However intimidating the process might potentially have been, Larry and his colleague Pey managed the overall process as well as our concerns or issues with ease and class. If you have the opportunity to book this company, you must. I can't imagine how we could have had a better experience despite the challenge our installations presented. Fast forward to today and we're generating an incredible amount of solar energy. Thank you, Cosmic!! read more

After one of the wood boards started to curl, Ron fit a visit to fix the issue, despite having a busy schedule. Ron fixed the issue and did not rush the job. He made sure the job was done right. If management from Cosmic Solar is reading this, please do everything you can to keep this reliable, hardworking gentleman with your company! I've had a lot of work done on my house, and have had a lot of issues. With Ron, I had zero issues, which was such a relief! He knows his craft and he's very professional. read more

Cosmic performed very well. Cosmic was the only company I interviewed that provided their own crews to perform ALL photovoltaic (electricity), pool (water) solar removal, installation and complete roofing services. The other 4 contractors I interviewed planed to sub-contract all or part of the solar system/s removal and installation or vice versa with the roofing. Cosmic was priced competitively (actually about $1K more) with the other contractors I interviewed, but because they were a 'one-stop' shop, I felt as though I was more in control over the end product and them living up to any warranties. And since I watched the entire process, learning along the way from working crews taking time to teach me what they were working on, I felt I now had sufficient knowledge about roofing and solar installations/removals to make better decisions in the future (hopefully 30-50 years). Also, if you are not prepared, roofing is a very noisy process from inside the home. 8-9 hours of constant hammering or banging each day. I am retired and had to find projects on the outside of my house to keep me busy, and I think now one of my dogs is just a little weirder. The crews that worked on/at my house were mostly very good, respectable and caring individuals. The crews were there (different solar and roofing crews) for about three long weeks during some rainy periods. At the end of each day they would spend their last hour or so cleaning up the roofing job debris surrounding my house. I have a pool that the roof extends closely to in one corner. A couple of the days I had to clean my pool from debris that made its way into the water. I was told by the foreman that the crew supervisors were instructed to cover up the pool, but then it happened a second time. I was not happy, but the foreman made reparations relating to that matter. Also, I have dogs that mostly kept the workers confined to the roof. The workers even compensated for my littler ankle-biter sneaking under one of the gates (pic). As well, the crews needed to be reminded by myself of keeping the gates closed. Overall the crew did a good job at maintaining a clean worksite, but I continue to find nails (pic) periodically in my equipment lot next to the house where I house RVs and utility trailers. I understand there is going to be some nails that may get missed with the magnetic brooms used daily, but continue to find one or two, especially after the first big rain where they washed from the gutters. The crews also had on occasion left a drink can/cup or other construction debris on the roof or in the yard that would be caught by the wind and taken into the lower areas of my property. I also noticed a few (3) cigarette butts scattered by where the crews parked in the mornings. The work crews began each day around 8am and were gone by 4:30pm. They would take coordinated breaks times that could often be anticipated . . . or, just wait until the hammering stops. I'm collectively giving them 4-stars because of some of their oversights along the way and I don't want future customers to believe they are perfect. I do think they are a pretty good and solid company. I would recommend them to anyone who asks; and comparing Cosmic to other roofing teams and other roofing projects I have since seen (yes, now you look at everyone's roof), I can understand the price I paid and the time it took. I had a pretty large and complex roof. Thanks Cosmic. Sorry, the pictures are just random shots during the process, and others were from leaks that had subsequently been handled. Dicks read more

Larry was our first contact with Cosmic Solar and we really appreciated all the information he provided for us and his patience in answering our questions. It was never high pressure and he even helped us months after installation in getting us information we needed for a rebate and fixing our EV charger. The whole process with Cosmic was easy and quick. I highly recommend Larry and the Cosmic team. read more

After months of research on solar companies in our area we went with Cosmic Solar because of their reputable reviews and we're very happy with the final installation. Jose Duran, Senior Energy Consultant, was the first person we talked to and he represents the company well because of his honesty, knowledge, professionalism, and friendliness. We were also impressed with all the office personnel (Ashley, Arlene and Mary) keeping us informed every step of our project, as well as the staff, (as our project advanced) Pey, Hector, Gilbert, Tom, Johnny, Ben and Javier were knowledgeable, clean, professional, polite, and hard working. If you want a great, honest experience and great solar, I strongly recommend using Cosmic Solar! read more

I've done business with Cosmic Solar twice - they are a first class outfit and if I ever need solar again I'll call them. They have excellent customer service - I can't emphasize this enough! Everyone I dealt with - salesperson, office worker, installers - was knowledgeable, polite, and efficient. I always have the feeling that the business is well run and the employees are treated well. They are honest (when I first called, years ago, they told me I wasn't using enough electricity to need solar), cheerful, and responsive. read more

Amazing services and great communication from Cosmic Solar, from start to finish. It is difficult to trust online reviews and contractors to ensure they will follow through with proposals and deliver quality services and products. From the very beginning, we reached out to Pey and he sent us a bunch of information and was very transparent. Cheers to Pey, Mary, and their team for a great experience! We were able to finish up everything in 7 business days: 1) 1.5 days for solar installation 2) Final Inspection 3) Wait for SDG&E to issue permission to operate 4) Then SDG&E reviewed and configured our meter remotely (with Smart Meter) 5) Pey from Cosmic Solar came back to our house to turn on solar on! Highly recommend this company! read more

We were planning to get solar installed for a while. Finally, we went for it and made the April deadline before the net metering rules changed. Although, we would have done the installation regardless. A big shout-out goes to Cosmic Solar and Roofing for providing us with stellar service. Pey Shadzi is an incredible wealth of knowledge and knows everything solar. Pey provided us with the best solar options based on our needs and usage. He is honest, personable, and genuine. The entire team kept us informed every step of the way and paid attention to all details. The team at Cosmic Solar made our installation a seamless process. Cosmic Solar and Roofing is a reputable company. Our solar is up and running, and I am thrilled to be doing our part for the environment. Several solar installation companies broached us, and some companies were pushy. That was not the case with Cosmic. Hands down, I recommend Cosmic Solar and Roofing for all your solar and roofing needs. This company goes the extra mile, and the whole process was a positive experience. It's clear that customer service is this company's priority. Thank you to the team, Pey, Mary, Ashley, Hector, and Witchy! read more

My roof leaked during the recent rain, causing water to drip from the kitchen ceiling and down the wall. My roofer came out twice; I have a ten-year warranty against leaks. He couldn't find the hole and said it must be under the solar panels. I called Cosmic Solar, and Jonny came out, took off one panel, and found the hole. He said it was probably caused when someone punched through with a drill accidentally. (I had recently had my water repiped through the attic.) Jonny fixed the leak at NO CHARGE. All my experiences with Cosmic Solar have been great, including my electricity savings! This is a great company! read more

We had solar panels installed and roof papering. The project from beginning to end was flawless. Larry Schmidt came to house and presented the cost and options, then they dealt with getting the permits, having the roof work completed by Davelos Roofing, and finally installing the panels (2 days only) and getting connected to SDGE. With two days of getting city inspection we had the PTO and getting power via the sun. No issues. read more
