Cosmo Solaris Reviews

This is my 2nd negative posting for Cosmos Solaris. It now March of 2026. I had system installed in December 2025. My system is still not fully functioning as per the agreement I paid for. Additionally, I cannot get Cosmos Solaris to schedule troubleshooting /repairs, and I cannot get them to schedule a final inspection with the county. The customer service has been completely unsatisfactory with no communication and constant ghosting. Horrible experience and I still do not have any commitment from Cosmos Solaris to get system operating per our contracted agreement or a final inspection scheduled to clear permit with the county. Absolutely terrible!

We are extremely satisfied with our solar installation from Cosmo Solaris. From the very beginning, their team provided great guidance and helped us choose the perfect solar system for our home. The installation process was smooth and their accuracy was impressive. We highly recommend them!
