  • "Solar done fairly easy!"

    Reviewed May 19, 2021

    We had a 25 panel installation done late last year via Invaleon. Since we live in a historic district, Invaleon was one of the few companies willing to work with us to determine a configuration that would work within our constraints. They were very receptive to our limitations as well as our needs, and helped in getting a very good price for the panels that we wanted. The installation was done on the promised date, and they helped in setting up our energy monitor as well. The owner even dropped by to ensure that the install was going smoothly. My only gripe is that being a small team, they do not always respond to emails quickly. But I've heard the same complaint from most solar companies, as most of them are small businesses with small teams and the pandemic has really thrown a wrench into their plans. Would recommend for anyone thinking of installing solar panels.

  • "Lots of options!"

    Reviewed May 10, 2021

    Very thorough on creating a system that would work best for us and had lots of panel options to choose from. Thank you Charlie for your help!

  • "Solar PV and the Pandemic"

    Reviewed Apr 27, 2021

    After using EnergySage to compare solar pv companies, Invaleon was chosen because they are a Tesla-certified installer and a Tesla Powerwall 2 was a key part of our system. After meeting with a representative who carefully explained the process, and after several visits by site reviewers, the turnkey contract was signed in July 2020, during the pandemic. Despite supply chain issues with both panels and the Powerwall, and the challenges of working safely in residential settings, the project was completed by the end of the year as promised. I have already recommended Invaleon to family and friends.
