System only producing 60% of guaranteed production and no response from them

Cosmo Solaris installed an 8 kW rooftop solar array on my townhouse in MD in 2025. Installation went smoothly. However, after one year of operation, I reviewed my system's production and it only produced 60% of the guaranteed production. So I contacted them to find out how they planned to rectify it, as the contract states they would either add more solar panels or write a check for the lost production. I emailed over and over and over and rarely got any responses. After over two months of emailing, they offered me a payment for the lost production, however the $/kWh rate they used was about half of what I pay. I showed them the correct math, and after over a month there has still been no response to that. Their guarantee is worth no more than the paper it's printed on. I do not recommend Cosmo Solaris.

No customer service!!!

Their customer service and warranty both are Jokes!!! I would have give them negative rating if I could. They installed 19 solar panels in Jnauary 2025. Three solar panels stopped producing electricty in July 2026. 7 more solar panels stopped producing any electricty in August 2026. You can never contact them over phone. I have sent numerous email and messages to them to diagnose the problem and repair. Till date they only shipped 3 replacement microinverts and nothing else. No technician to diagnose and repair the problem. They offered warranty through "Align Solar Protection" company. However, that solar protection company also didn't do anything so far except replying some emails. As a result my solar system is producing only 45% electricity and there is no end in sight for our misery

Avoid

Update time Picked them based on promising a additional warranty. They took from March to Dec 2025 to finish installing. They never completed the secondary warranty. So now its gone. They have cut off all communication on all platforms. My panels dont work well 3 of 21 does. They went off line back in June 2026. Nobody came out nobody reached out nobody returned any emails or calls. Avoid this company

Total Incompetence

This has been one of the most frustrating experiences I’ve had. The team has no project management capabilities and no continuity for delivery. The project has been ongoing with no updates on timing and no customer services.

Abandon Job - Costing Me Thousands to Fix

Job started well enough with panels installed, but then came the electrical connection and commissioning. It took two months and several tries for their electrician to get the system functioning. There were several appointments made that their electrician just didn't show for without any notice to me. Over the next several months - January to June - they managed to fail three separate inspections from my county. Ultimately they stopped showing up, stopped communicating, and I'm left with several thousands of dollars of work to correct the pathetically noncompliant electrical work. Check with your state's home improvement licensing agency for their status. In Maryland I'm told that they may have multiple active complaints.
