    DRASTIC negative Susten representative experience. Their agent "Leo" ( broken language) stated that he would be at my residence, scheduled NOT by me,
    to finalize a SIGNED contract quote with additional "adjustments". I emphatically stated I made no such request for home visit. I will NOT pursue solar by this experience and energysage as a recommended consumer resource. I will be referring this experience to Consumer Protection and attorney general of CT.

    Ms. Gail Fahey,

    We don't even do in-person sales visits these COVID days... everything (except site-survey and the installation itself) is performed online. You either misundertood me or lied in your review.

    My name is "Leo"... I'm the CEO of the company that I founded 8 years ago and am proud to have always service my clients and employees with respect.

    I'm a Biochemical Engineer with specializations in Project Management, Project Finance, Green Building, Renewable Energy, Carbon Emission Reductions and Sustainability, being trained and certified in USA, Germany and Brazil.

    I'm not an "agent" or "phone quote representative" as your prejudice has led you to think I was and which probably triggered your offensive behaviour against me.

    I founded and run this company to provide services to people who respect each other, those who believe in hard-work, the American Dream, and that building a more sustainable society is possible and necessary.

    I don’t service xenophobic people who negatively treat others based on language accent, physical appearance or birth nationality.

    I knew (in my gut) that you would give me a bad review, but I do not regret and will not apologize to have (respectfully) hanged up on you.

    I'm human.

    Best Regards,

    Leandro Pena-Salvatico (Leo)

    Reviewed Aug 17, 2020

    I purchased a system from Susten, it was installed, I think we were a bit delayed due to Covid. After a month the inverters failed, but they were replaced under warranty. He arrived timely to perform the warranty work which was appreciated.
    The install was performed in a neat and professional manner, and the system is producing above spec at this time.
    They made an effort to accommodate my needs here and modified the system to to meet my preferences.
    Great job, Thanks

    Thanks for your negative feedback as it helps us get better. We are glad we successfully completed your project installation exactly as initially designed-contracted, even under the COVID-19 circunstances, which was far from ideal. The State of CT as well as MD, DC, NJ and NY imposed work restrictions that complicated everyone's businesses and lives.

    We’d always wondered how to help out with the environment and change our carbon footprint. A representative from Susten Energy went to our area and we started talking about the possibilities of working with our local utility company, and the grants were available. They handled things with our local township for the zoning stuff and our electric company. The process and installation was smooth and easy.

    "When other companies won't touch your roof..."

    Reviewed Nov 13, 2016

    I've been researching going solar for 2 years. After contacting the 6 highest rated solar companies that I found on an independent website that rates the top 100 companies in the nation in a variety of fields, I still had no panels for my townhouse.

    Four of the companies disqualified me right over the phone while talking to me, due to the size and shape of my roof. One, Blue Raven Solar, at least sent 2 reps over to my house. They never went up to my roof, never took any measurements, never even looked at my circuit breaker box in the basement. The only thing one of them did was take a picture of the large tree in my neighbors back yard, that was a potential sunlight blocker, and tell me what a great and wonderful company they were, and that they'd get back to me. But they never did, not even after I emailed them again right after their visit to my house. They did not even show the professionalism to respond to my email.

    Solar city on the other hand did send a real engineer. He looked at my electrical system. He went up on my roof and took measurements and sunlight shade readings. They tried to make a system that would produce 50% of my electric needs. But a few days later they pulled out too, when they couldn't put the minimal 8 panels on my roof, due to NY state laws that require 2 ft of clear roof space along the parameter of your roof for fire fighters. They I cannot say anything against. They simply weren't equipped to outfit a home like mine, but they really did try and kept me informed throughout the whole process.

    Then came Leandro Salvatico from SustenCorp. He custom designed a system for my impossible to fit roof that would hold FOURTEEN yes fourteen solar panels. It was innovative and is hardly noticeable when you stand in front of my house. It was a marvelous creation by Leandro.

    My electric bills which average around $135 a month, dropped the last 3 months to - $15, $18, and $38. His engineer David Lam who did the entire installation, saw through all the bugs that cropped up. And there were several, but he never stopped till he fixed each one, and I got the great production I'm getting now.

    If you have a small or oddly shaped roof, save yourself a lot of time and headaches I had to go through and have SustenCorp come over and custom design a system that will work where other companies won't even try.
