In late October, after a delay beyond my control, I obtained 3 bids for a solar system in an attempt to meet the Dec 31 tax credit deadline. I'm an engineer with professional registration in 11 states, and have led many major projects around the world; I did not really believe it could be done.Sierra, the lead contact with CosmoSolaris, provided the most complete bid with high-quality equipment at a reasonable cost. Sierra was very pleasant to work with, and extremely prompt in replying to my requests and possible options. She was very knowledgeable and cognizant of the need for an efficient time schedule. She scheduled the site inspector for the next day, a Saturday. After a couple of discussions regarding less than optimum roof angles and winter tree shading with Martin, the lead designer and Project Manager, the revised model design was completed. I agreed with Sierra on the Final Agreement (she gave, and kept her word on a key final term that I was concerned with), and the install race was on.Cosmo submitted the final designs and obtained County permit approval extremely quickly (from experience, I know that is not always easy), and scheduled installation. I quickly replaced the marginal roof section, and their team installed the entire system on one mid December day, dodging snow and freezing temperatures elsewhere in the East. I can just imagine the challenges the Cosmo teams had with numerous system installs in progress simultaneously, all with the same deadline, the two major holidays, and the lousy polar vortex weather occurring across the country.The final County electrical inspection took literally one minute, since the high-quality install was evident, and the County's "Final Passed" document and the verification from Martin were both in my inbox in less than a half hour. The deadline was easily met! A couple days later (not the anticipated month), the utility granted approval to activate the system. I threw the switch on the morning of Dec 31! It has been interesting and exciting watching the blue graph of the Enphase app showing power generation, even on cloudy days!I don't know all the players on the Cosmo team, but the behind the scenes organization and efficiency was obvious, as the County, Utility, Enphase software, PJM, GATS, accounting, and tax form paperwork and approvals seem to just appear in my inbox - almost completely filled out with minimal for me to do. There are only a couple remaining minor tasks to complete.I am very happy to have become my own little home power plant, with top-of-the-line panels and microinverters, all designed and installed in record time. CosmoSolaris was up for the challenge and met the tax deadline. Thank you all !
We just got our solar panel installation completed, and we are very pleased with the entire process. Cosmo Solaris offered a competitive system price--- AND they answered ALL of my 100’s of questions BEFORE I signed on with them…!Sierra was my main point of contact, and she professionally shepherded us through the process from start to finish. She was great to work with and very knowledgeable. And I appreciated how she gave me the opportunity to earn referral bonuses...! Also, I needed a new roof, and they found me a high-quality, experienced roofing group that did a great job and at a very reasonable price. After installation, I am now able to monitor my solar panel’s energy output via a phone app--- And I’m looking for to the long summer days, where my panels will be earning me major solar energy credits…!
I have had a terrible experience with Cosmo Solaris. I signed my contract with them in July 2025. As of today's date, of Dec 11 2025, I still do not have a solar system that is fully functional. The installers showed up and installed system but did not have a critical component that left the system only able to charge the battery. It seems the site meter was not configured. Without a site meter, system will not operate fully. I am highly disappointed. It took Cosmo Solar over 3 months to get the permitting approved and another 2 months to get materials and install date on the calendar. Throughout the process Cosmo Solaris customer's service has been horrible. I could not get anybody to answer or return phone calls or text for my project status. So here I sit with a system not functioning properly and Cosmo Solaris will not provide me any updates as to when they will come back to install missing components, final inspection or commissioning of the system. It has been a terrible customer service experience. I see no end in sight.
We recently used Solaris to install our solar panels. Installation went fine they took care of the design, paperwork, approvals, visits on a timely fashion. I was impressed by their communication. Great shout out to Sierra and Alex to take care of the project for us. I am excited to wait and see the performance. Great work so far.
Great guarantees with this professional outfit. Our system was installed, up, running and interconnected in a timely manner. We appreciated that they incentivize themselves to stay on schedule with the “we will start paying your electric bill if you’re not done in 10 weeks” promise. Top quality components were utilized and it all looks very tidy and professional. Their time of arrival estimates for deliveries and installation dates were pretty far off, but they did show up on the days they scheduled and the end result was a quality installation done in a timely fashion. Mike and his team were readily available to answer any and all questions so we knew exactly what to expect.
