    "Reliable Solar Panels Installer"

    Reviewed Apr 03, 2017

    Alex-sun was the solar contractor we chose for our Solar Panel installation project. Both my wife and I have been extremely pleased with the quality of service we have received from Alex and his team. The work was performed on schedule and with a high degree of precision. All issues that entail such an endeavor were managed in a timely and professional manner. We have no hesitation in recommending that anyone considering either a residential or commercial solar energy project to definitely consider Alex-sun as their prospective contractor.

    Alex was phenomenal, accommodating and very flexible. He was very knowledgeable about regulations, rebates and loan programs and helped every step of the way with those.
    We wanted to go beyond just the PV Solar panels that Alex-Sun provided and installed, and include Solar Hot Water. Alex wanted to expand his repertoire and he encouraged and helped us with that installation as well. I was particularly impressed with that.
    Through all this, Alex's commitment to the environment came shining through!

  • "Great Experience!"

    Reviewed Dec 07, 2016

    Alex was great to work with, from start to finish! While he is a relatively new installer, he wasn't overly pushy in his sales pitch. He was always open and honest throughout the inspection, design, install, financing, and post work phases. His turnaround time - a little over a month from start to finish - was a difference maker in my decision to go with his company over other proposals and he stuck to that timeline. The install and inspection did not hinder my normal routine much at all, either. I've had several questions after install and Alex still remains in contact.

    I highly recommend Alex for your solar needs!

  • "Solar Panels to save energy"

    Reviewed Dec 06, 2016

    Alex DeFreitas did a superb job of figuring out what electrical energy would be generated, obtained all the required permits, helped with the financing process and installed a solid and neat looking 35-panel aray on our roof.

    I am his structural engineer for reviewing roof framing and designing modifications as might be needed to safely support the panels. Alex is great to work with and knowledgeable about solar panels, installing them and understanding the complexities of the electrical work done by his subcontractor.
