    "Quality Installation and Great Customer Service"

    Reviewed Jul 07, 2022

    My solar system was installed by Invaleon Solar four years ago. After getting a few quotes from EnergySage, I decided to go with Invaleon as they did another project in my town. Looking back after four years, I feel I should provide a review since enough time has passed for my review to be credible. First, Charlie Roche of Invaleon came up with a great design taking into consideration of system capacity and layout. I signed the contract in June. It took a couple months to get permit and good weather for them to start installation. The installation was fast and finished in just two days, thanks to some prep work Invaleon did in advance. I wish it had taken shorter time from start to finish but a lot of things were out of Invaleon's control.

    Since my system was up running, there has been no issue, generating electricity consistently. This speaks for the quality of craftsmanship on Invaleon's part. They were also responsive in answering any questions I had during the installation.

    Two years ago, one of my neighbors across the street was considering solar and he also ended up choosing Invaleon. He is equally satisfied.

    Overall, I have nothing but good things to say about my experience with Invaleon.

    Before I get to the negative review of Invaleon Solar that I chose them to install the system on my house on the beginning of Nov 2021, I would like to thank Charlie and the solar panel installation guys, they were awesome and great.

    After obtaining different quotes on Energysage and elsewhere, I finally decided to go solar thinking it could save me some money in the long run and do some good to the environment. I chose Invaleon and signed contract with them to do the work on Nov 5th, 2021. After about 2-3 months since signing the contract, I finally got email from them saying we've got the permit. Then the solar installation guys came around Feb 2022 and completed the installation in 5 days, which is fast and great. When I thought I could finally run the long awaiting solar system on my house, oh not yet.

    It took them more than 2 weeks to get the city's inspector come and then took them forever to get the utility company to install the meter. You really had to follow up with them for what's going on and if not, they will never get back to you with an update, which is the most frustrating part. With the spring/summer on the way, I feel like missing a lot of the good sunshines and of course the solar electricities. The solar panels have been sitting on my roof since Feb and they're not doing anything as of right now and I don't know when they will be up and running.

    I have another friend who's waiting for me to get my solar system done and give him some feedback and referrals on whom to go with for his solar system. I was once impressed by Invaleon team and now I don't feel like giving him the referral.

    This review is solely related to the customer team, installation process and the project team. Nothing to do with the quality of the solar panels or the labor and parts of Invaleon. I will update once the system is up and running.

    - Update on 5/2;

    Carrie from Invaleon reached out to me and explained what was going on with the delay, after that I was finally able to turn on the system one week after our convosation. Thanks Carrie and the team and I can tell that Invaleon is really caring about their customers.

    I will update on the quality of the solar system after a few months from now.

    Right from the start, Charlie was easy to work with, never tried to oversell, and was very courteous. Communications were prompt, clear and accurate. The solar Install was very professional and went smoothly; the crew was great and in and out in no time - completely hassle-free.
    DJ and his crew did an amazing job on the electrical upgrade and went above and beyond in running the line out to the level 2 charger. And they’re nice guys to boot! They even went out of their way to conceal the conduit where they could!
    I wish every interaction with contractors went this smoothly...
