This company might be great at solar panels, but they clearly struggle with respecting people’s requests. How many times do I need to tell them they have the wrong number before they actually stop messaging me?

Customer Reviews
Bibiana Velasquez
Samantha is a great solar advisor and highly recommend. She explained every single step, and answered every question and continuously check on us to make sure everything is running smoothly. Just a peace of mind to have control over energy cost now and future... now I only pay the utility company at times around $14 and get credits from energy unused. This is definitively one of the best decisions ever made.
