SUNation back office support is excellent. They kept me updated on every step of the process. On installation day, the mechanics were very professional. Very neat. No unnecessary roof penetrations. The system works flawlessly.

From start to finish the process went smoothly. The system that was sold to me not only met, but exceeded my expectations. My PSEG bill is a thing of the past and the system looks great on my house.

They offer many options for inverters and panels to fit my needs. They kept me included in the design process as well as supporting documents for estimated production. Installation was smooth and took about 6 hours for 17 panels. Very easy to get in touch with the office staff to ask questions and the permit process closed out easily.

I researched multiple Solar companies for nearly a month before settling on SUNation. I chose SUNation because their sales representant, John, went above and beyond to answer all our questions (he came to my house on three separate occasions). Even after contracts were signed John was extremely attentive and continued to answer my questions as we moved throughout the process. In addition to John the guys that came out for the field assessment, the women in the office, and the guys that installed the system were AMAZING. Everyone was so kind, patient, and helpful from start to finish. They communicate with you throughout the whole process. I highly recommend SUNation.

I have been using Sunation since 2009. Our original solar system, which was installed by another company, had design flaws in the battery back up system. Sunation helped us fix those flaws. When we remodeled our home, we needed to remove our existing system. The only company we called was Sunation to remove and then replace our system with an updated system was Sunation. The experience and professionalism of Sunation mechanics are outstanding. I would not use any other Solar Co in the Nassau/Suffolk NY area.

Seal of Approval

What is the screening process that Service Professionals go through in order to become members of the HomeAdvisor network?

  1. Verify Trade License
    HomeAdvisor checks to see if the business carries the appropriate state-level license.
  2. Verify Insurance
    As a part of our screening process, we encourage professionals to carry general liability insurance. We require coverage for hundreds of services.
  3. Verification of State Business Filings
    For business types that require a Secretary of State filing, we confirm that the business is in good standing in the state in which it is located.
  4. Criminal Records Search
    HomeAdvisor uses 3rd party data sources to conduct a criminal search for any relevant criminal activity associated with the owner/principal of the business.
  5. Sex Offender Search
    We confirm that the owner/principal is not listed on the official state Sex Offender web site in the state in which the owner/principal of the company is located.
  6. Bankruptcy Search
    We use 3rd party data sources to check the history of the principal/owner of the business for bankruptcy filings by or against them.
  7. Legal Search for Civil Judgments
    We use 3rd party data sources to check the principal/owner of the business for state level civil legal judgments entered against them.
  8. Liens Search
    We use 3rd party data sources to check the principal/owner of the business for liens placed against them.
  9. Identity Verification (SSN)
    HomeAdvisor verifies the social security number(s) of the owner/principal for identity check purposes. This check applies primarily to smaller business entities.
  10. Identity Verification (Reverse Phone Lookup)
    We conduct a reverse business phone lookup to identify records matching the phone number information provided by the business.

NOTE: Member service professional information confirmed as described above may change or expire over time; while HomeAdvisor attempts to maintain accurate and up-to-date information, and confirms changes when notified, we cannot guarantee that profile and screening information is accurate.
