"Stephanie was very professional the times we spoke. She is very pleasant and knowledgeable. She wasn’t pushy and actually listened to and answered any questions that I asked. I was very interested in going solar. My wife said no. She doesn’t want panels on the roof or anywhere in the yard. Sorry"

"It was pleasure to work with the All Energy Solar team for the design, installation and post installation support of my home solar power system. Every aspect of my relationship with AES was professional, supportive and actually fun. Working with Justin Growel on initial design was smooth and informative. My project manager, Carlo Maloni, provided excellent support before, during and after installation to ensure that the whole process went smoothly, including all necessary permits and inspections with local government and our power utility. I can't say enough about the excellent installation crew who were total professionals as well as friendly and answered any questions that I had during the installation process that only took a few days. I will definitely recommend All Energy Solar to other home owners looking to install a home solar system!!"
