EnergySage vets solar installation companies and offers a few recommendations for consumers which gave me peace of mind, especially since EnergySage is a subsidiary of the Dept of Energy. It is also a great educational tool to help buyers navigate through the purchasing process. Ultimately, we chose Apollo Energy. We are in the beginning stage but Apollo has been excellent at explaining the process, educating us on the quality of the solar panels and have been great at communicating, offering weekly updates and always inviting us to contact them with questions.
