Bay Solar is one of the most professional solar companies I have ever dealt with. From the start they plan your solar journey. Listing your solar goals and requirements. Showing you what your potential saving per month will be once their system is installed. Their installation is neat and professional. Once your system is up and running they continually monitor it to make sure it performance and maximum to give you the benefit. In the unlikely event you have any issues their after sales service is phenomenal. Quick to react an quick to sort out any issues. I am extremely happy with their installation and service and will continue to use them for the planned upgrades in the future.
