Work in progress

Cosmo Solaris installed my solar in August of 2025. I have had a myriad of issues, but I can say that they have been responding and our working with me to get them resolved. I will update this review even more positively if they follow through and fix these issues

Production Shortfall

Used Cosmo in November of 2024. One year later i have a 25 Percent shortfall from contract. 15 phone calls and multiple e-mails and text and crickets......... I was assured that it would be taken care of........ But its been 4 months so. You can draw your own conclusion.

We hate to leave a bad review but...

We never leave negative reviews, but it is difficult to describe the headaches we have suffered as a result of using Cosmo Solaris. This review is only highlighting some of our difficulties. First, they created delay by refusing our assistance in getting our permit approved; it was then followed by their inability to properly install our inverter and battery; we then had to deal with the fact that the permit that took forever had not been properly applied for, so we had to wait significantly longer while they filed for the necessary permit. Next, we had their failure of workmanship that caused a failed inspection; after we finally passed inspection, we then had their claim that our system was operating in September, which proved to be wrong and it wasn’t operating at all until November 1, 2025. We then had their refusal to deal with EG4 (the maker of our inverter and battery) to make our system barely operational, requiring us to spend hours with the very helpful but spread thin EG4 between waiting to talk to someone and then talking to someone. Currently, despite their assurances that they would correct the problem if we made our last payment, Cosmo has been ignoring us for months to correct a subpar installation that is averaging less than 10 kWh even though we paid for and they guaranteed a system that averaged 42.7 kWh per day. We are not blindsiding Cosmo with our concerns; we have all of our texts and emails where we have asked for them to honor their responsibilities, yet they continue to be unresponsive.

Hooked the battery up wrong so it never kicks in!

Initially I was very happy with Cosmo Solaris. They do a great job of organizing everything and getting all the approvals from the County and the local utility. They use very high quality materials sourced from Canada and they generally adhered to the schedule they proposed. In addition, the guys who came out to install the panels were really polite and professional. However, after they left I realized my well pump wasn't hooked up and I had no water for a few days until they came back and fixed it. Then, later when I lost power the battery never came online. They eventually put me in touch with someone from Enphase, the equipment supplier, who determined they had hooked the battery up wrong and it would never kick in and provide power. Plus, several of the microinverters kept going offline and right now the entire controller system has been offline for more than a month. I've emailed Cosmo Solaris several times and they keep saying they're getting me scheduled -- but weeks go by and nothing happens. So, I can't say I'd recommend them.

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.
