Recent Reviews

(Based on 31 reviews)

Reviews frequently mention clear communication, patient explanations of the solar process, and guidance on incentives and utility billing. Several customers note timely installation timelines and smooth coordination from paperwork through activation. Feedback also highlights ongoing check-ins and assistance with optimizing production. A small number of comments mention unwanted messages to the wrong number as a frustration.

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?

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.
