Outstanding Project Management and Communication

I had a great experience working with Cosmo Solaris on my solar installation. From initial design through final permission to operate, the process was well organized and professionally managed. John served as my project manager and was excellent throughout the project. He was very responsive, kept me informed at every step, and made sure I understood what was happening and what was coming next. When I had questions or wanted to discuss details, the team was flexible and willing to work with me rather than pushing a one-size-fits-all approach. I also had a firm timeline I needed to meet, and Cosmo Solaris exceeded expectations by completing the project about a month earlier than planned, including installation, inspections, and utility approvals. Overall, communication, execution, and follow-through were strong, and the system is now up and running as expected. I would absolutely recommend Cosmo Solaris to anyone considering solar, especially if you value clear communication and reliable project management.

Working through some issues

Update: Cosmo agreed to honor the contract we signed. I will update this once Everything is resolved. Cosmo reneged on the contract we signed within 1 year and is ignoring the Better Business Bureau and the Maryland Attorney General's Office. In 2024, Cosmo Solaris installed a PV system on our house. The contract we signed stipulated that I could receive a bonus for each successful referral I sent to Cosmo or, for three referrals, I could instead receive a free battery backup system. After sending more than six referrals to Cosmo told me that the offer only applied for a limited time and I missed the window. When I brought the issue up again, Cosmo said it only applied if they made a certain profit margin on those systems and their profit margins on my referrals were not sufficient for a battery backup. I reviewed the contract carefully. It has no expiration or stipulation about profit margins for the referral bonus. Cosmo then tried to shut me up by sending me an unauthorized deposit to my account that was half of the prior referral bonuses. Cosmo is offering excuses for not fulfilling their end of the contract. They are in material breach of contract.

Hard to believe this is a functioning business

As the title says I find it hard to believe this is a functioning business. They contracted everything out to third parties and those installers were amazing. However, Cosmo Solaris made mistakes that anyone with a little bit of experience would never have made. They hire people with the title of "Project Manager." The way the Project Manager communicated made it clear they had no experience in electricity or roofing in any way. They could not explain how they would complete the line side tap, and attempted to design the system so it backfed through a 200 amp breaker at my meter base. I communicated several times that I had installed a triple barrel lug below the meter and the lines would need to be cut at the street to safely complete the line side tap. They instead wanted to just open one of my 200 amp breakers on my 400 amp service and complete the tap through the 200 amp breaker. I wound up scheduling a disconnect and making the connection myself. They then "redrew" the prints for AEP showing the exact same backfeeding and I had to draw the prints for them. They then wanted to get paid in full before everything was approved by AEP. They said it would take 3 weeks for the new prints to be approved and they didn't want to wait that long. They were also 3 months late in installing the system and were frequently very late in responding to all forms of communication. They also could not keep an appointment if their lives depended on it and would not call to tell you they couldn't make it. They'd just let you wait all day. I fully expect them to go out of business in the near future.

Great Customer Service--- AND they helped me get a New Roof...!

We just got our solar panel installation completed in December, and we are very pleased with the entire process. Cosmo Solaris offered a competitive system price--- AND they answered ALL 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. Jeff was my project manager, and he kept me informed throughout the project. 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. I am now able to monitor my solar panel’s energy output via a phone app. I am now waiting to see the selected solar panels perform-- and I’m looking forward to the long summer days, where my panels should be earning me major solar energy credits…!

Exceptional warranty coverage

The backup coverage they offered was very compelling along with extremely competitive pricing, but unfortunately, we couldn't proceed due to our plans to sell the house in the next 3 to 4 years. Happy to recommend them to the new owners if they decide on solar!

Helpful and Knowledgeable

I had a great experience communicating with Zayn. Although I decided to hold off on my solar installation for now due to some tax credit reasons, I really appreciated how professional and transparent he was. He explained everything in detail and never pressured me into making a decision. I’ll definitely consider moving forward with them in the future!
